Fully insulated stainless steel solid doors maximize thermal stability and exclude ambient light — appropriate for storage of photosensitive biologics, controlled substances, and high-value pharmaceutical inventory.
• Hydrocarbon R290 natural refrigerant with low GWP: Environmentally responsible R290 hydrocarbon refrigerant delivers high thermodynamic efficiency, eliminates HFC global warming potential, and meets EPA SNAP refrigerant rules and ASHRAE compliance guidelines.
• Three adjustable shelves for flexible interior organization: Adjustable wire shelving supports a range of freezer storage container types — including standard 2-inch and 3-inch cryo boxes, microcentrifuge racks, primer and reagent storage, antibody aliquot boxes, and tissue specimen trays.
• 3/4″ probe access port for external temperature monitoring: A pre-installed 3/4-inch probe access port supports integration with continuous data loggers and building management system probes without breaking the cabinet seal — supporting 21 CFR Part 11, ISBER biorepository documentation, and audit-ready electronic temperature records.
• Keyed door lock and high-density urethane foam insulation: Cylinder keyed door lock provides chain-of-custody control for controlled-substance, biospecimen, and high-value sample storage; foamed-in-place high-density urethane insulation maintains setpoint stability and reduces compressor duty cycle across research laboratory deployments.
• Safety-shielded interior monitoring and swivel casters: Sample-simulated temperature monitoring with RS-485 (MODBUS) digital communication supports integration with central environmental monitoring networks; mobility-ready caster mounting simplifies placement, leveling, and floor cleaning across laboratory and pharmacy environments.
• Two (2) years parts and labor warranty with five (5) year compressor parts warranty: Plus Series extended two-year parts and labor coverage plus a five-year compressor parts warranty supports total cost of ownership planning for high-utilization institutional and pharmaceutical deployments.
• ETL Listed; NEMA 5-15 power cord conforms to UL 471 requirements: ETL listing and power cord conformance to UL 471 commercial refrigerator/freezer standards confirm safety and performance, supporting institutional procurement requirements and capital equipment review processes.

Frequently Asked Questions – ARES Cool 23 Cu. Ft. Plus Series Stainless Steel Auto Defrost Laboratory Freezer (-30°C Operation)

What is the ARS-HC-SSP-23FA3 laboratory freezer used for?

The ARS-HC-SSP-23FA3 is a 23 cu. ft. ARES Cool Plus Series stainless steel auto-defrost laboratory freezer with a -27°C to -35°C operating range. Typical applications include enzyme and reagent storage, competent cell preservation, primer storage, antibody aliquot storage, intermediate-temperature biospecimen archival, and pharmaceutical inventory storage across research laboratories, clinical diagnostic labs, hospital pharmacies, and pharmaceutical manufacturing facilities. The stainless steel cabinet construction supports cGMP-regulated and cleanroom-adjacent environments.

What is the difference between the ARS-HC-SSP-23FA3 (−30°C operation) and the standard ARS-HC-SSP-23FA?

The two freezers share the same 23 cu. ft. stainless steel cabinet, three adjustable shelves, microprocessor temperature controller, auto-defrost design, R290 refrigerant, and ETL listing. The functional difference is the operating temperature range: the standard SSP-23FA operates from −15°C to −25°C for general-purpose laboratory freezing, while the SSP-23FA3 extends to −27°C to −35°C for workflows requiring deeper freezing — antibody long-term storage, primer and competent cell preservation, and intermediate biospecimen archival between standard −20°C and ultra-low −80°C storage. Both share identical exterior dimensions (27″ × 36″ × 83.25″), weight, and electrical requirements.

What are the electrical and installation requirements for the ARS-HC-SSP-23FA3?

The ARS-HC-SSP-23FA3 operates on standard North American power at 115VAC / 60 Hz / 1PH and draws 8 amps through a NEMA 5-15 plug conforming to UL 471 requirements. Exterior dimensions are 27″ wide × 36″ deep × 83.25″ tall, with a total open depth of 59.25″ when the door is fully swung. The unit ships with swivel casters for placement, leveling, and relocation. Operating environment must be indoor only, +18°C to +26°C (+65°F to +78°F), at less than 70% relative humidity. Specify adequate top and rear clearance for compressor ventilation during installation.

Is the ARS-HC-SSP-23FA3 compliant with laboratory accreditation and pharmaceutical manufacturing requirements?

The ARS-HC-SSP-23FA3 is ETL listed and the NEMA 5-15 power cord conforms to UL 471 — the safety standard for commercial refrigerators and freezers. The 3/4-inch probe access port and remote alarm contacts support continuous temperature monitoring required by ISBER biorepository best practices, CAP and CLIA laboratory accreditation, and 21 CFR Part 11 electronic record requirements. RS-485 (MODBUS) digital communication enables integration with facility environmental monitoring networks. Stainless steel cabinet construction supports cleaning validation in cGMP and pharmaceutical manufacturing environments. Buyers pursuing specific USP general chapter or institutional pharmacy compliance should confirm validation documentation requirements directly with ARES Scientific.

How does the ARS-HC-SSP-23FA3 compare to other ARES Cool laboratory freezers and cold storage options?

The ARS-HC-SSP-23FA3 sits within ARES Scientific’s ARES Cool cold storage line — the proprietary refrigerator and freezer family distributed exclusively by ARES. The full ARES Cool stainless steel laboratory freezer range includes 23 cu. ft. and 49 cu. ft. capacities, with the 23 cu. ft. cabinet available in both standard −20°C and extended −30°C operating configurations. For applications requiring sub-zero storage beyond the freezer category, evaluate the ultra-low temperature freezer range supporting −80°C and below. For paired refrigerated and frozen storage in a single footprint, refrigerator/freezer combination units are also available within the broader cold storage portfolio.

Why does the ARS-HC-SSP-23FA3 use R290 refrigerant, and what is the GWP?

The unit uses hydrocarbon R290 natural refrigerant — a propane-based refrigerant with a global warming potential (GWP) of approximately 3, compared to legacy HFC refrigerants such as R134a (GWP 1430) and R404A (GWP 3922). R290 delivers high thermodynamic efficiency, which directly improves freezer pull-down time, temperature uniformity, and compressor duty cycle. It also supports EPA SNAP-approved laboratory and medical freezer applications and aligns with institutional sustainability commitments and ASHRAE compliance guidelines. The hermetic compressor is sealed and serviced as a unit by qualified refrigeration technicians.
