ARES Cool 14 Cu. Ft. Explosion-Proof (Hazardous Location) Laboratory Freezer ARS-HC-EFP-14

Description

ARS-HC-EFP-14 – Product Highlights

• Class 1, Division II Groups A, B, C & D rated — engineered for classified rooms where flammable vapors, gases, or dust may be present in the surrounding atmosphere, meeting NFPA 70 and OSHA hazardous-location guidelines.
• ATEX and non-sparking components throughout — eliminates internal and external ignition sources, including a vapor-proof compressor enclosure and absence of interior lighting that could otherwise act as an ignition point.
• Hardwired conduit installation — ships without a power cord per Class 1, Division II convention; final connection at the install site is hardwired in conduit to 115V, 60 Hz facility power to meet local electrical codes.
• Microprocessor temperature controller with digital display — delivers tighter setpoint control, faster recovery, and more accurate verification than the mechanical thermostats common to legacy explosion-proof equipment.
• Adjustable −15°C to −25°C range — suitable for solvent storage, volatile-reagent freezing, intermediate chemistry samples, and similar applications across the hazardous materials freezers and refrigerators use case.
• R290 natural hydrocarbon refrigerant — low global warming potential refrigerant with strong thermodynamic performance, paired with EPA-compliant high-density urethane foam insulation for stable interior temperatures.
• State switching remote alarm contacts plus audible and visual high/low alarms — integrates with facility BMS and centralized monitoring infrastructure for after-hours and unattended operation.
• Six fixed interior shelves and keyed door lock — supports organized sample storage, restricted access for controlled or sensitive materials, and a rear wall probe port for external calibration and continuous monitoring devices.
• ETL and C-ETL listed to UL 471, ENERGY STAR Certified — independent agency listing for the hazardous-location application plus verified energy performance, useful for sustainability reporting and facility-level utility planning.
• Two-year parts and labor warranty — ARES Cool is ARES Scientific’s proprietary cold storage line, distributed exclusively by ARES Scientific with full warranty support and U.S.-based customer service, and listed within the broader ARES Scientific cold storage refrigeration portfolio for facilities outfitting both classified and unclassified rooms.

Frequently Asked Questions – ARS-HC-EFP-14

What is a Class 1, Division II freezer and how does it differ from a standard laboratory freezer?

A Class 1, Division II freezer such as the ARS-HC-EFP-14 is engineered for rooms classified under NFPA 70 as locations where flammable vapors, gases, or volatile chemistries may be present in the surrounding atmosphere under abnormal conditions. Standard laboratory freezers are not rated for these atmospheres and can act as ignition sources through interior lighting, defrost heaters, or control electronics. The EFP-14 eliminates those ignition sources through ATEX and non-sparking components, sealed vapor-proof enclosures, and conduit-only electrical termination.

What is the difference between an explosion-proof freezer and a flammable storage freezer?

The distinction is room classification, not stored contents. An explosion-proof unit like the EFP-14 is rated for classified rooms where the atmosphere outside the cabinet may itself be hazardous. A flammable storage freezer is rated for ordinary, unclassified laboratory rooms and protects against ignition of flammables stored inside the cabinet. Using the wrong tier — flammable storage in a classified room, or explosion-proof in a non-classified room — is a code-compliance error in both directions.

Why does the ARS-HC-EFP-14 ship without a power cord?

Class 1, Division II equipment must be hardwired in conduit per NFPA 70 to prevent the cord-and-plug interface from acting as an ignition source in a classified atmosphere. The EFP-14 is configured for hardwired termination at the install site to 115 V, 60 Hz facility power. Final connection should be performed by a qualified electrician familiar with local hazardous-location codes; cord-and-plug installation is not an acceptable shortcut for this product class.

What applications and industries typically deploy explosion-proof laboratory freezers?

Typical deployments include solvent dispensing and storage rooms in academic and industrial chemistry programs, cannabis extraction and post-processing suites, pharmaceutical pilot plants and process development labs, forensic toxicology facilities, petrochemical and refining R&D, and analytical testing facilities outfitted through ARES Scientific’s broader hazardous materials freezers and refrigerators portfolio. Selection should be driven by the room’s electrical classification on file, not by the contents being stored.

Is the ARS-HC-EFP-14 NFPA and OSHA compliant?

The EFP-14 is ETL and C-ETL listed and certified to the UL 471 standard, is ENERGY STAR Certified, and meets NFPA and OSHA guidelines for Hazardous Location, Class 1, Division II, Groups A, B, C and D. Compliance is product-level; final installation compliance depends on the facility’s classified-area drawings, the electrician’s conduit and termination practice, and local AHJ inspection.

Does the unit include interior lighting?

No. Interior lighting is intentionally omitted because incandescent or LED fixtures inside a Class 1, Division II cabinet would constitute a potential ignition source unless they are themselves explosion-proof rated, which adds cost, failure modes, and maintenance burden. The microprocessor controller is mounted externally and the interior is kept free of spark-producing components.
