Temperature rasing and falling 3 degree PID Control Digital Constant Temperature

Product Specification

PID Control Digital Constant Temperature and Humidity Test Chamber

Technical Parameters of desktop temperature &humidity chamber:

1.Feature with environmental test chamber:

1. Graceful appearance, circularly shaped body, surface treated with mist strips, and plane handle with no reaction. Easy to operate, safe and reliable.
2. Rectangular double-glassed watching window for the observation of the test production during the testing process.The window is equipped with sweat-proof electrical heating device that can prevent water steam from condensing into droplets, and with high brightness PL fluorescent bulbs to provide light inside the box.
3. Double-layer-insulated airtight doors, able to insulate the internal temperature effectively.
4. Water supply system that is externally connectable, convenient for refilling water into the humidifying pot and automatically recyclable.
5. The French Tecumseh brand is used for the circulation system of the compressor, capable of removing the lubricant between the condensation pipes and capillaries. The environment-protecting coolant is used for the whole series (R232,R404)
6. Imported LCD display screen is used for the control unit, capable of displaying the measured value as well as the set value and time.
7. The control unit has the functions of multiples segment program editing, and of quick or slope control of temperature and humidity.
8. Inserted mobile pulley, convenient for movement a relocation, with strong positioning screws.

2.Refrigeration/Dehumidification Systems

2-1 Refrigeration Accessories:

2-1-1 Compressor:

Vortex cascade type mechanical refrigerating system
Good refrigeration scale, low noise, low energy consumption, high efficiency.
Two compressors are used for the machine to ensure Long-term & stable operation

2-1-2 Refrigeration Evaporator:

Finned evaporators are used for increasing heat exchange efficiency by 30%.
This evaporator has the advantages of beautiful look, compact shape, and fast cooling effect.
 

2-1-3 Oil Separator & Refrigeration Oil: Enough high-quality refrigeration oil is most important for
Refrigeration compressor, which will directly affects its service life. If the refrigeration oil runs into
refrigeration system, especially into heat exchangers, the performance will greatly reduces. So oil
separator with best performance is provided for this machine, with stable viscosity.
 

2-1-4 High Efficiency Condensing Evaporator: The world advanced brazed plate heat exchanger is used for
high heat transfer intensity, also this exchanger is not easy to scale
 

2-2 Cooling Mode: Mechanical cooled /air cooled
 

2-3 Main Refrigeration Accessories: Solenoid valve, manual valve, filters, expansion valve, pressure
Controller, vibration absorber tube, diminisher, electronic expansion valve are all world famous brand.
 

2-4 Refrigerants: R22, R23 or R404A, which is totally environmental friendly.
