Thermal shock chambers can test material structure by detecting chemical changes or physical damage caused by thermal expansion and contraction in the shortest time through continuous environment at very high temperature and very low temperature.

Two Zone Thermal Shock Test Chamber Testing principle mainly through controlling the portable basket (test samples District) to quickly move between cryogenic tank and high temperature tank to achieve rapid thermal shock test.  The whole testing process test samples along with mobile gondola to move together.

High low temperature(Three Zone)Thermal shock chamber is consist of High temperature test area(Pre-heating area), Low temperature test area(Pre-cooling)area and test area(RT), adopt independent wind path switching mode to transfer hot and cold air to test area make sure the high low temperature swift, the test sample shall not move during the test.

Whether it is a three-zone or two-zone chamber, the interior of the chamber is constantly experiencing rapid collisions and cycles of high and low temperatures, which will undoubtedly cause great damage to the machine itself.  If it is not well maintained and maintained, it will affect the machine’s longevity and normal use.  Relying on years of experience in the production of environmental test chambers, Sanwood Technology collects and organizes maintenance tips on the maintenance of Thermal shock chamber.

1. Clean the condenser regularly every three months: For air cooling type, the condenser should be regularly overhauled, and the condenser should be decontaminated to ensure its good ventilation and heat transfer performance;  For water-cooled cooling type , it should be ensured its influent pressure, influent temperature within the specified range.  It must also ensure the corresponding flow rate, and regularly clean and scale the condenser to obtain its continuous heat transfer performance.

2. Thermal shock chamber for a long time to do low temperature, as a cycle, should set the temperature of 110 degrees, small open box door for two hours defrosting treatment.  And after each test, the temperature should be set near the ambient temperature, work for about 30 minutes, then cut off the power supply, and clean the inner wall of the studio.

3. Thermal shock chamber should be cleaned regularly: because the cleanliness grade of the sample is different, under the action of forced wind circulation, the evaporator will condense a lot of small particles such as dust, which should be cleaned regularly.

4. Low temperature test box circulating air blade, condenser fan cleaning and balance: similar to the cleaning evaporator, because the working environment of the test box is different, the circulating air blade, condenser fan will condense dust and other small particle objects, should be cleaned regularly.

5.  If you need to move the thermal shock box, please operate under the guidance of the company's technicians to avoid damage to the equipment.  If the customer moves by himself, an electrician must confirm that the circuit is correct before starting.  Otherwise, the equipment related components will be burned out.

6. If the thermal shock chamber has been used for a long time, and it should be regularly energized for at least 1 hour every half month, and the operation of related parts of the equipment should be tested
