Category Explosion-Proof Refrigerators & Freezers
Manufacturer Marvel Scientific
Country of manufacture the United States of America

The Marvel Scientific MS24RFSHRW (formerly 6ERF) is a 6.1 cubic foot Hazardous Location Refrigerator/Freezer that is appropriate for noncritical temperature storage applications. Hazardous Location products are often referred to by the industry term “Explosion Proof”. The MS24RFSHRW uses a “U” shaped plate-type evaporator installed across the top of the interior, which is isolated from the remainder of the interior space by a spring-closing interior door and thermal divider, to create a small amount of dedicated freezer space. The remainder of the interior is refrigerator storage space.

The MS24RFSHRW features a static condenser and requires additional ventilation clearance when installed under a bench. Construction features include a specially designed compressor, overload, relay and thermostat system with all electrical components enclosed to prevent accidental ignition of flammable vapors present in the ambient environment surrounding the refrigerator/freezer. The MS24RFSHRW is supplied with a two-wire pigtail for hardwire connection to an appropriately rated conduit box. When installed under lab benches or within casework the 6ERF requires additional ventilation clearance of 1″ from top and sides of the cabinet and 1.5″ from the back to insure proper static condenser ventilation.

The MS24RFSHRW complies with the following specifications and standards:

  • Listed by Underwriters Laboratories for Class 1, Division 1 and 2, Group C and D applications
  • Wiring complies with National Electrical Code, Article 501-4 for Class 1, Division 1 and 2
  • Complies with ANSI/UL 1203 Standard, NFPA 70 and NFPA 99


  • Specially designed compressor with all electrical components fully enclosed, to prevent an electrical spark from accidentally igniting any flammable vapors present in the ambient environment surrounding the refrigerator/freezer
  • Static condenser mounted to the back of the cabinet, free of electric condenser fan motor to eliminate sources of accidental ignition of flammable vapors
  • Adjustable mechanical thermostat, fully enclosed to prevent ignition of flammable vapors
  • Manual defrost protects refrigerator/freezer contents from automatic defrost freeze and thaw cycles and dehydration
  • 2 adjustable and removable interior wire shelves
  • 3 interior door shelves
  • “Box Style” door
  • Discrete top edge mounted door handle
  • 4 leveling legs for easy height adjustment
  • 2 wire pig-tail for hardwire connection
  • Durable white powder coat paint finish standard

    NOTE: Marvel Scientific refrigerators and freezers are manufactured at the time the order is placed and then put through rigorous testing to ensure quality before they are released. A lead time of approximately 2-3 weeks should be expected
