*The test requirements that need to reach below -40 degrees will
use a cascade double compression refrigeration system. When the
test is above -20 degrees, only one compressor will be started to
work with a smaller power heating tube for inching heating, which
saves electricity and water; ( If single-stage refrigeration is
used, the compressor will be equipped with high-power full-process
refrigeration, and the refrigeration capacity is also large, and a
higher-performance heating tube is required to balance, so it
consumes electricity and water.
*The sink is made of special materials with low thermal
conductivity and no water droplets on the surface (such as metal
materials will form water droplets on the surface, which will
easily wet the sample and affect the test results), and is equipped
with a diversion device. If the sink appears When the internal
pressure is too high or the water level is too high, it will flow
into the humidification barrel through the diversion hole.
*The cascade dual-compression refrigeration system can easily meet
the test requirements of low temperature -40 degrees and below.
When the single-stage refrigeration reaches -38 degrees, it will be
difficult to drop to -40 degrees. This is due to the
characteristics of R404A refrigerant. It can only be achieved by
temperature compensation.
*The machine is exquisite, the internal space is large, the
external dimension is small, the width is only about 78cm, and the
single-door laboratory can be easily entered.
*There is a pressure relief hole on the top.
