Ultra-Low Freezers feature a unique insulated inner door design with four separate storage compartments to minimize frost buildup inside the chamber. These inner doors are also designed for independent access of storage space for maximum protection of stored samples. Each door is sealed for minimum loss of cold temperature during a door opening.
ULT Freezers have a microprocessor-controlled system which is designed for controllable range of -40° to -86°C with 1°C increments. The high-performance VIP insulated panels minimize cabinet heat gain and improve temperature stability. The specialized control system gives a well-balanced operation of cascade refrigeration system. The multiple built-in system protection features include user-settable protection code for controls, user settable delay to start, voltage compensation system, and protection against extreme high voltages. Malfunction alarms include high & low temperature, power outage, sensor errors, high & low voltage, clean-filter, and extremely high ambient..
