◆Box built-in shelf: stainless steel SUS #304 square punching steel plate shelf 1 piece and 4 sets of rails (adjust the spacing)；

Test Chamber Refrigeration system

◆ Refrigeration system: using French Taikang compressors, European and American high-efficiency power-saving ultra-low temperature refrigeration systems (air-cooled heat dissipation method);

◆ Cold and heat exchange system: Ultra-high efficiency SWEP refrigerant cold and heat exchange design (environmental protection refrigerant R404A);

◆ Heating load adjustment: Automatically adjust the refrigerant flow rate to effectively take away the heat emitted by the heating load;

◆ Condenser: Fin type motor with heat dissipation;

◆ Evaporator: fin type multi-stage automatic load capacity adjustment;

◆ Other accessories: desiccant, refrigerant flow window, repair valve;

◆ Expansion system: capacity control refrigeration system.

Test Chamber Control System

◆ Control system: programmable color screen touch screen temperature controller

◆ Chinese and English liquid crystal display LCD touch panel, screen dialogue type input data, temperature and humidity can be programmed at the same time, back light 17-segment adjustable, curve display, set value/display value curve. Various alarms can be displayed separately. When a fault occurs, the fault can be displayed on the screen to eliminate the fault and eliminate the mis-operation. Multiple groups of PID control functions, precise monitoring functions, and displayed on the screen in the form of data.
