Marvel Scientific 24" Undercounter Hazardous Location Refrigerator

Overview

The Marvel Scientific MS24RASHRW (formerly 6EAR) is a 6.1 cubic foot Hazardous Location Refrigerator that is appropriate for non-critical temperature storage applications. Hazardous Location products are often referred to by the industry term “Explosion Proof”. The MS24RASHRW uses a “U” shaped, plate-type evaporator installed vertically across the top of the side and rear walls of the interior. Its large surface area efficiently absorbs heat to cool the well-insulated interior which is all refrigerator space.

The MS24RASHRW 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. The MS24RASHRW 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 MS24RASHRW 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 MS24RASHRW 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

Features:

• 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
• 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
• Auto cycle defrost eliminates the need to manually defrost the refrigerator
• 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
• Built-in door lock available for secure storage

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
