Performance Plus / Dual Shield / AULT530DC

Protect irreplaceable samples.
Plan the space around them.

Build your ultra-low storage around a 530-liter cabinet with two independently operating compressors, insulated inner doors and temperature records at the touchscreen. The Accucold AULT530DC gives research teams a considered alternative to a larger full-capacity freezer.

Select a setpoint from −86°C to −40°C. Accucold states that, if one compressor fails, the remaining compressor can maintain −80°C while service is arranged. Pair that protection with a documented alarm response and a suitable backup-storage plan.

Is this the right freezer?

Choose the storage environment before the cabinet.

Start with the material’s required storage conditions, your inventory plan and the facility’s operating procedures.

Research materials requiring ULT storage

For laboratories organizing biological samples, reagents and other research materials that require temperatures within the published range. Match each material’s storage instructions to the selected setpoint; the freezer is not a universal suitability guarantee.

Redundancy matters to your operation

The Dual Shield arrangement is useful when a single compressor failure must not immediately leave the cabinet without cooling. It does not provide compressor operation during a mains power outage or replace an emergency response plan.

A smaller upright fits the inventory plan

Choose the 530 L configuration when its capacity supports the expected workload. Compare it with the larger 779 L AULT780DC before buying room for inventory you do not expect to hold.

Your facility can support the installation

Plan a dedicated grounded supply, ventilation, a suitable floor and heavy-equipment receiving. Choose another storage format when the required temperature, access route or working environment does not fit.

Layers of protection

Limit exposure. Keep conditions in view.

  • Two insulated inner doors: access one part of the storage area without exposing the entire chamber directly to room air.
  • VIP vacuum insulation: supports the cabinet’s thermal envelope alongside the stainless steel interior.
  • Lockable access: mechanical and electronic locking support controlled use. Optional biometric or card-access hardware should be specified separately rather than assumed included.
  • Alarms and remote contacts: make local warnings part of a broader facility response. An external alarm system is separate equipment.

The manufacturer’s compressor-failure statement is specifically a −80°C condition. Do not treat it as an unconditional −86°C promise or a guarantee against loss of stored materials.

Know what arrives

A freezer cabinet, not a fully racked sample library.

Included with the base freezer

The AULT530DC cabinet includes three adjustable shelves, two insulated inner doors, the 10-inch touchscreen, USB interface, probe-access ports, remote alarm contacts, four casters and two leveling legs. The manufacturer supplies NEMA 5-15P and NEMA 6-15P connection options.

Specify and order separately

Storage racks and boxes, external alarm or monitoring equipment and any factory-installed monitoring/access upgrades require separate confirmation. A USB drive, sample containers, padlock or props shown in manufacturer photographs are not established as included items.

Use the delivered packing list and the user manual to check accessories before startup. Cabinet capacity and an optional rack layout are different ordering decisions.

Organize the inventory

Choose one box-height layout, then confirm rack fit.

Accucold publishes two alternative full storage layouts for this model. The figures are not additive, and neither layout means racks or boxes are supplied with the base cabinet.

Manufacturer storage illustration with optional racks and boxes installed. Racks and boxes are separately ordered; this is not the base scope of delivery.
Manufacturer storage illustration with optional racks and boxes installed. Racks and boxes are separately ordered; this is not the base scope of delivery.

Two-inch box layout

Up to 400 two-inch boxes using a full configuration of 16 racks, per the model-specific specification sheet.

Three-inch box layout

Up to 240 three-inch boxes using a full configuration of 16 racks. This is the alternative taller-box layout, not an additional capacity.

Confirm the actual box footprint, rack part numbers, shelf positions and retrieval workflow before ordering accessories. Keep the temperature sensor and required airflow clear, and plan how staff will identify and retrieve samples efficiently.

A rack quantity is a quantity of racks per freezer. It is not a quantity of freezers and does not make unpriced accessories part of the equipment price.

Optional rack configuration

Two-inch box storage

Plan up to 400 two-inch boxes using the manufacturer’s full configuration of 16 racks. Racks and boxes are separately quoted and are not included in the freezer price.

Exact rack part numbers, box fit and pricing require confirmation.

Optional rack configuration

Three-inch box storage

Plan up to 240 three-inch boxes using the alternative full configuration of 16 racks. Racks and boxes are separately quoted and are not included in the freezer price.

Exact rack part numbers, box fit and pricing require confirmation.

Monitoring and response

Make the record useful when someone needs to act.

The 10-inch touchscreen provides access to temperature curves, stored records, alarm history and user activity. The USB interface supports data export, while probe access and remote contacts allow a monitoring plan to extend beyond the cabinet.

  • Assign responsibility: name who checks readings, reviews alarms and responds outside normal working hours.
  • Separate functions: the alarm/control backup battery does not power the refrigeration compressors.
  • Plan escalation: specify any separate monitoring equipment against the required temperature range and your facility’s procedures.

For another monitoring approach, see the related PharmaWatch monitoring family. Select the exact kit, probes and service scope separately; this link does not make a kit included or establish universal compatibility.

Site and delivery planning

Measure the route. Prepare the room. Confirm the supply.

Plan receiving doors, corridors, corners, elevators, unpacking and final placement before selecting delivery services. Use the official technical drawings and delivered installation instructions for final site approval.

Receiving and floor support

The published unit weight is 608 lb; the model-specific sheet lists 735 lb shipping weight. Confirm unloading and inside-placement arrangements. The supporting floor must accommodate the fully loaded operating installation, not just the empty cabinet.

Ventilation and environment

The manual calls for at least 30 cm at the back and both sides, with vents unobstructed. It specifies indoor operation at 16–32°C ambient. A narrow enclosed installation is not an acceptable substitute for ventilation.

Electrical preparation

The model supports 115V or 220V connection and includes the two specified plug types. Use the suitable single grounded supply connection and confirm the delivered rating label with your facility’s electrician. The two plugs do not represent independent backup power.

Make the freight quote specific.

Provide the full shipping address, receiving dock or liftgate requirement, access restrictions and any inside-placement request. Stairs, elevators and white-glove services should be discussed explicitly rather than assumed to be part of standard delivery.

Confirm the final cabinet and packed dimensions from current technical documents before committing to a route. Keep door-opening space separate from the ventilation allowance and the packed shipping envelope.

From arrival to routine operation

Allow for settling, stabilization and deliberate loading.

1 · Position and prepare

Move and level the cabinet using suitable equipment. The user manual requires it to stand for more than 24 hours after placement before power-on. Follow the manufacturer’s instructions for the delivered unit and check the installation before connecting it.

2 · Stabilize before loading

Complete the initial no-load checks described in the manual. Introduce materials in controlled batches, avoid bulk-loading warm items and limit door opening during pull-down. Do not confuse an empty-cabinet performance figure with a validated loaded process.

3 · Keep the storage plan working

Record checks and alarm actions, maintain airflow and arrange suitable alternative storage for maintenance. Follow the specified filter-cleaning and defrost procedure; manual defrost requires a planned transfer of contents.

Care belongs in the equipment plan.

Use insulated gloves and appropriate handling procedures for ultra-cold surfaces. Keep door seals dry and ventilation clear. Before defrosting, move materials to suitable storage and follow the manual; do not use sharp tools or unapproved heating methods. Refrigeration repairs and flammable-refrigerant work belong with authorized, qualified service personnel.

Answers before you order

AULT530DC buyer questions

Does Dual Shield keep the freezer at −86°C if a compressor fails?

No. Accucold’s stated failure condition is that the remaining independently operating compressor can maintain −80°C when one compressor fails. That is different from the normal adjustable −86°C to −40°C range. It is not a mains-outage backup or a guarantee against sample loss.

Are the storage racks and sample boxes included?

No. The base scope includes three adjustable shelves and two insulated inner doors. The published 400 two-inch-box or 240 three-inch-box layouts use optional racks. Confirm exact rack and box part numbers, footprint and quantities separately.

How many racks does the AULT530DC full layout use?

The model-specific sheet lists 16 racks for either published box-height layout: up to 400 two-inch boxes OR 240 three-inch boxes. These are alternative layouts, not a combined storage count. Confirm your exact container and rack configuration before ordering.

Can this model connect to either 115V or 220V?

Yes. Accucold specifies dual-voltage operation and supplies NEMA 5-15P and NEMA 6-15P connection options. Use the appropriate single grounded supply connection and the delivered rating label. Do not treat the two plugs as simultaneous independent power or backup circuits.

Does the backup battery run the compressors during a power outage?

No. The manual describes battery support for alarm/control functions, not compressor refrigeration. Your facility should have an outage-response and alternative-storage plan appropriate to the stored materials.

What should we check before arranging delivery?

Confirm the complete delivery route, packed dimensions, unloading capability, final floor support, ventilation, working clearance and electrical supply. The empty unit is 608 lb and the specification sheet lists 735 lb shipping weight. Discuss liftgate, inside placement and other services before the shipment is arranged.

Can we export temperature records or connect separate monitoring?

The cabinet provides a touchscreen and USB data-export interface, remote alarm contacts and probe access. Select any separate monitoring system, probes and service agreement for the required temperature range. The presence of records or a connection does not by itself validate a regulatory or facility-specific monitoring program.

Can we load samples immediately after delivery?

No. Follow the manual’s settling, no-load startup, stabilization and staged-loading instructions before placing materials inside. Its arrival procedure calls for more than 24 hours standing after placement before power-on. Do not rely on an empty-cabinet pull-down figure as permission to load warm materials immediately.

How does manual defrost affect the workflow?

Plan a suitable transfer location for stored materials and schedule maintenance using the manufacturer’s procedure. Disconnect and defrost as instructed, protect ultra-cold surfaces appropriately and let the freezer return to the required setpoint before reloading. Do not use sharp tools or unapproved methods.

Who handles order returns and manufacturer warranty service?

Start ordinary order-return requests with Blue Tiger Scientific and obtain written authorization before shipping anything. Accucold/FSI handles manufacturer warranty coverage and service directly. The model manual lists a five-year limited appliance warranty and 12-year compressor replacement coverage; compressor replacement labor is excluded, and written terms, territory and other exclusions apply.

    Blue Tiger Scientific is a reseller, not the manufacturer. We manage your purchase and order-return requests. Accucold, a division of Felix Storch, Inc. (FSI), handles manufacturer warranty coverage, service and repairs directly.

    Ordering and delivery

    Availability, dispatch timing and freight depend on the selected equipment, configuration and destination. Delivery dates shown on this page are estimates, not guarantees. Supplier processing, lead time and carrier transit can affect arrival. Contact Blue Tiger before ordering if you have a firm deadline or specific receiving requirements.

    For the base equipment, standard dock or liftgate delivery charges to the 48 contiguous United States and Washington, DC are calculated at checkout. Select dock delivery only if a suitable receiving dock and unloading capability are available. Alaska, Hawaii, US territories and international destinations require a quote. Measure the complete access route and prepare the installation site using the manufacturer’s instructions.

    Standard delivery does not include inside placement, stairs or white-glove services. If additional services are needed, Blue Tiger Scientific will review access, elevators, delivery level and placement requirements and provide a separate quote for your approval before any additional service charge is billed.

    Inspect your delivery

    Inspect the shipment when it arrives. Keep the original cartons, packing materials and delivery paperwork. Report damage, shortages or an incorrect item to Blue Tiger immediately at info@bluetigerscientific.com, with photographs of the item, packaging, shipping label and delivery receipt.

    For freight arranged by FSI or delivered on FSI trucks, FSI instructs recipients to refuse visibly damaged units and have the driver record and acknowledge the damage on the delivery paperwork. On a multi-unit shipment, refuse the damaged units rather than the undamaged remainder. Concealed damage must be reported within five days after delivery acceptance; contact Blue Tiger immediately so the manufacturer’s reporting deadline can be met.

    For customer-nominated, collect or third-party-carrier shipments, claims must be pursued with that carrier. Do not assume FSI will accept a freight-damage return. Contact Blue Tiger for the order information and instructions before arranging any return shipment.

    Order returns must start with Blue Tiger

    All order-return requests must be initiated through Blue Tiger Scientific at info@bluetigerscientific.com. Accucold/FSI does not provide an automatic buyer’s-remorse return right. Eligibility and written authorization must be confirmed before anything is shipped.

    • Contact Blue Tiger within 14 days of delivery to request review, subject to the product-specific manufacturer restrictions. FSI does not accept an eligible factory-sealed return after 30 days from its original shipment date, so request review promptly enough for an authorized return to meet that deadline.
    • Include your Blue Tiger order number, exact manufacturer part number, serial number if applicable, quantity, contact details and reason for the request. Provide the photographs required for the manufacturer’s review.
    • Wait for written return authorization and the designated return address. Do not send an order return to Blue Tiger’s business address or directly to FSI without these instructions.
    • For an eligible non-defective stock return, FSI requires the original unopened carton and an undamaged appliance in new condition. Opened packages are not accepted under that return route.
    • FSI applies a 25% restocking charge per eligible returned item and may charge a higher percentage on larger orders. Your authorization will state the applicable charges. Original outbound freight, including embedded freight on a shipment, reduces the return credit.
    • The customer is responsible for approved non-defective return freight and insurance. Use the authorized carrier and instructions supplied for this heavy equipment. Damage, incorrect-item and defect reports are reviewed separately from an unwanted-product request.

    Customized and factory-upgraded equipment

    FSI excludes made-to-order models with customizations from ordinary returns. Its listed exclusions include factory-installed thermometers, alarms, data loggers and digital-thermostat upgrades, as well as specified lock, door and cabinet customizations. Do not assume a factory-upgraded configuration is returnable. Confirm the exact model’s eligibility before ordering.

    Manufacturer warranty and service go directly to Accucold

    The AULT530DC user manual lists a five-year limited warranty for the appliance and a 12-year compressor warranty. Extended compressor replacement coverage does not include replacement labor. Coverage, exclusions and eligible service locations are governed by the model’s written manufacturer warranty.

    Contact Accucold/FSI directly for warranty coverage questions, claims, service assignment and repair authorization: service@accucold.com or 718-893-3900. Technical questions can be directed to techsupport@accucold.com. Have your model, serial number, proof of purchase, delivery location and a description of the problem ready.

    Blue Tiger Scientific does not administer manufacturer warranty claims, authorize warranty repairs or provide warranty service. Do not commission an independent repair or send equipment for service until FSI provides authorization and instructions. Service not assigned or authorized by FSI may not be covered.

    Manufacturer coverage depends on proper installation, operation and maintenance. The written warranty includes exclusions for matters such as misuse, improper installation, unauthorized modifications and consequential losses, including product spoilage. Equipment warranty coverage is not a guarantee of stored-material value or reimbursement.

    International destinations and service areas

    International customers should request a quote to confirm the equipment configuration, destination eligibility and shipping arrangements. Confirm responsibility for any import duties, taxes and brokerage in the quote. International returns are not permitted under Blue Tiger Scientific’s published return policy.

    The model manuals describe warranty coverage within the 48 contiguous United States and selected areas of Alaska, Hawaii and Canada. Contact Accucold/FSI directly before purchase to confirm warranty availability and service arrangements for your exact delivery location. Do not assume worldwide on-site service is included.
