The MS24FASHRW (formerly the 4EAF) is a 4.5 cubic foot Hazardous Location Freezer that is appropriate for non-critical temperature storage applications. Hazardous Location products are often referred to by the industry term “Explosion Proof”. It uses a “G” shaped plate-type evaporator installed across the top of the interior. Its large surface area efficiently absorbs heat to cool the well-insulated interior which is all dedicated freezer space.
The MS24FASHRW 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 freezer. The MS24FASHRW 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 MS24FASHRW requires additional ventilation clearance of 1″ from top and sides of the cabinet and 1 1/2″ from the back to insure proper static condenser ventilation.
The MS24FASHRW 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 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 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 freezer contents from automatic defrost freeze and thaw cycles and dehydration
