Machine features

*-At temperatures above 20 degrees, only one 375W compressor is used in conjunction with a 1KW heating tube for incremental heating, saving energy and water; If single-stage refrigeration is used, the compressor is 1.5 horsepower, which is 1125W, and works with a 2.2KW heating tube. It has a large cooling capacity and strong dehumidification function, so it consumes only 750W of electricity and does not save water. When dual compressors are started, it is only 750W.

*The sink is made of special materials with low thermal conductivity and no water droplets on the surface (if metal materials are used, water droplets may form on the surface, which can easily wet the sample and affect the testing effect). It is also equipped with a flow guide device. If the internal pressure or water level of the sink is too high, it will flow into the humidification bucket through the flow guide hole.

*Easily achieve a low temperature of -50 degrees and a maximum temperature of -55 degrees. When single-stage refrigeration reaches -37 degrees, it is difficult to further reduce to -40 degrees due to the characteristics of R404A refrigerant, which can only be achieved through temperature compensation. Third party inspection of -40 degrees may reveal an error of 2 to 3 degrees.

*The machine is exquisite, with a large internal space and small external dimensions, with a width of only about 60CM. The single door laboratory can be easily accessed.

*There is a pressure relief hole attached to the top.
