Floor Type Large Volume Temperature Humidity Cyclic Environmental Test Chamber Energy Saving
Scope of application:
This equipment is suitable for various types of electrical and
electronic products and other product, components and parts and
materials to high and low temperature constant and gradual change,
humidity and heat test Environmental simulation reliability test;
Other uses May cause injury to personnel and damage to machinery
and equipment.
Cooling systems of Climate Test Chamber: single-stage and
cascade (two stage) systems:
Single-stage compressor refrigeration system, supports temperatures
as low as-37°C (-35°F) and conforms to both commercial and military
standards for low-temperature tests.
For temperatures below -37°C, a cascade refrigeration system should
be used, and can generally support temperatures as low as -73°C
(-100°F). The low temperatures obtained with cascade systems occur
when two separate, closed refrigerant circuits run concurrently,
but each uses dedicated refrigerant and its own compressor.
The way that mechanical refrigeration systems are designed is
critical. Check to see that it is a self-contained system. Choosing
a unit that is a hermetically or semi-hermetically sealed unit will
make operation and maintenance an easier process.
Test limit:
1. Inflammable,explode, effumability test and storage of material
samples
2. Corrosive material sample test and storage biological sample
test or storage.
3. Strong electromagnetic emission source specimen test and
storage.
