Cooling system
1.The refrigerating system equips France Tecumseh, and uses environmentally friendly refrigerant (R404a). Adopting binary low temperature circuit system design, it is convenient to use different compressors for work in different temperature regions.
2.Temperature and humidity control using P.I.D + S.S.R system coordinated control with the same channel. It has the function of automatic calculation, which can immediately modify the temperature and humidity change conditions to make the temperature and humidity control more accurate and stable.
3.High-precision controllers of temperature and humidity. The relative temperature and humidity performance is accurately set and displayed with a resolution of 0.1℃.
Temperature and Humidification System
1.Temperature system using Nickel-chromium alloy high-speed heating electric wire;
2.High temperature system is completely independent;
3.The humidity system using stainless steel tube built-in nickel-chromium alloy high-speed heating electric wire and high-temperature magnesium oxide powder, which has fast response and long life;
4.The temperature and humidification system is completely independent, and humidity has automatic water supplement device.
Chamber Design Features
1. High performance and quiet operation (68 dBA)
2. Space-saving designed for flush installation to wall
3. Full thermal break around doorframe
4. One 50mm diameter cable port o left, with flexible silicone plug
5. Accurate wet/dry-bulb humidity measurement system for easy maintain
