The White Diamond Series Built–In Under counter Freezers feature a microprocessor temperature controller and display, which allows for precise temperature control, verification and recovery versus mechanical style thermostats. An interior fan driven, forced-draft air circulation system provides excellent temperature uniformity and recovery after door openings (Refrigerators only). Critical samples and supplies are security backed with an extensive package of audible and visual alarms. The Under counter 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.
