4.2 Cu. Ft. White Diamond Series Built-In Solid Door Auto Defrost Undercounter Freezer

Product Number: PF051WWW/0A

NLS Natural Refrigerant Labelul  

The White Diamond Series Built-in Undercounter Freezers feature a microprocessor temperature controller and display, which allows for precise temperature control, verification and recovery versus mechanical style thermostats. Critical samples and supplies are security backed with an extensive package of audible and visual alarms.

**The Undercounter Built-In models are designed with a “front-breathing” ventilation system, eliminating the need for clearance around the top and sides of the unit; enabling the user to incorporate these units into cabinets and other applications where space is limited.

Nor-Lake Scientific is Going Green!  We are an industry leader in providing a variety of Refrigerators and Freezers that are built with Hydrocarbon Refrigerants, R290 or R600a.

Environmentally friendly, natural hydrocarbon (HC) refrigerants (not containing hydrofluorocarbons) vastly reduce global-warming potential (GWP) while meeting new EPA/SNAP mandates and UL, ASHRAE compliance guidelines.
