Features:

High-texture appearance, the surface handled through the matte stripes, easy to operate, safe and reliable.
View window with anti-sweat heater device that prevents water vapor condensation, and high-brightness PL light.
Double-insulated airtight container, which can effectively isolate the internal temperature of leakage.
With an external water supply system can be easy to supply water and automatically reuse.
Compressor circulatory system from French "Tecumseh", more effective removal of oil between the condenser and the capillary and use environmentally refrigerants (R23, R404, R507).
Controller imported LCD display screen can be displayed measuring values and setting the value and time.
Controller with multi-segment program edited, temperature and humidity can be controlled quickly (OUICK) or slope (SLOP).
Built-in mobile pulley easy to move and has a strong positioning screw fixed position.
