Ultra Low Temperature Freezer Rooms Budzar Industries Ultra Low Temperature Freezers are designed to store and protect critical samples. The Budzar Industries Ultra Low Temperature Freezers address cold storage concerns by reliably storing material at temperatures ‹30º.   Each Budzar Industries Ultra Low Temperature Freezer is constructed for temperature stability within 1ºC gradient.  Multiple fans provide precise air circulation ensuring temperature stability.    A PLC Temperature Control Systems with PID cability provides temperature accuracy within 1º C and is essential in preventing under/over temperature swings. The system also features finger-safe terminal blocks, large on-board non-volatile memory, Real Time Clock capabilites for data monitoring and adjustments.   Multiple temperature sensors distributed throught the Ultra Low Temperature Freezer constantly monitor the temperature.  A temperature probe is strapped to the evaporator coil continually monitors the evaporator temperature.   Due to inherent moisture accumulation on the coil surface, a defrost cycle is required - either hot gas or electric defrost.  This defrost cycle is initated when the temperature difference between teh coil and room sensor reaches the critical set point.  The defrost cycle design includes: A door limit switch which turns off the cooling unit whenever the door or doors are opened Defrost heaters around door seals and drip pan Drain pipe and heat trace Critical Temperature Alarm Features of the Ultra Low Temperature Freezer include: Temperature Stability throughout the room PLC Temperature Control System with PID Capability Multiple Temperature Sensors 100% Redundancy Hot Gas or Electric Defrost Cycles   Download Product Sheet (PDF) Request a Quote
