The products are widely used in aerospace, electronics, automotive, metal, information, and instrumentation industries for simulated environmental testing of materials, components, electrical products and equipment.

Features
*High-T blast bypass flue, 3-level speed controllable recycling freezer, meeting the criterion of Europe & America product standard.

*Super sized (150mm×50mm) LCD equipped, intelligent programming controller based on fuzzy PID controlling technique, 30 programs pre-set, It could work for 99 cycles, with time, temperature and humidity. Video and audio alarms are installed.

* ABB Pt100 resistance temperature sensor imported from German, EBM cooling freezer imported from German, international branded sealed refrigerant, PU casters are equipped under the bottom could be turned and locked as needed.

*The handle of the outer door is locked by a 90o rotary lock with 4-point touch which shows German & Americas style and used for compulsory seal. Such a design prevents any vibration from throwing down the little bottles kept in the box when the door is closed., Observation window of the door is equipped with anti-condensation and a waterproof light equipped outside of the inner box top. Turn on the lights can be all-round observation inside the situation. Stainless steel (S.S) clapboards are supplied for users to adjust themselves. An observation hole corked withφ40mm silicon plug is installed on one side of the box, which makes the monitoring more efficient.

* Quenching gas recycling system ensures the uniformity of temperature and humidity. Various functions are prepared, such as leakage protection, over-temperature alarm and protection, low-water alarm, appointed startup and shutdown, clock memory, live line indicating, interruption memory, power supply recovery, etc.

*Numerically controlled machine and the combined technology of laser cutting and modulus are employed in sheet metal processing. The outer box is made of cold-rolled steel in high quality, and the tank is made of No. 304 S.S plate. The outer   box is powder sprayed and the bottom of the box is weld with rectangular steel, so that the strength of the whole chamber has reached the international level of similar products. 3-layered heat insulation is applied in the chamber, which is made of dense PU or superfine glass wool heat preservation material and reaches the production standard in the world.

* Safety protection device
Refrigeration system: overheating, overcurrent, overpressure of the compressor, overheating of the condenser fan protection devices.
Chamber: with adjustable over-temperature test space temperature fuse, air-conditioning limited over-temperature, fan motor overheating protection device
Other: fit the power with a phase sequence and phase loss protection, leakage protection, overload and short circuit protection devices.
Note: due to temperature and humidity requirements of different users, product appearance, configuration and structure may have difference.
