The whole system is a closed liquid circulation system with the expansion of container,expansion of the container and the liquid circulation is adiabatic, and did not participate in liquid circulation, only mechanical connection, regardless of the temperature of liquid circulation is a high temperature or low temperature expansion of the medium container of low at 60 degrees.
Throughout the liquid circulation system is sealed, low temperature did not absorb water vapor, high temperature did not produce the oil miss. The entire circulatory system is not used in machinery and electronic valves.
1.Wide working temperature range with cooling and heating function, temperature range:-30~180 degree.
2.With 2pcs of LED display controller, can show the setting temperature& actual value, and alarm value for over-temperature.
3.Efficient fast, simple topping up liquid.
4.Ensure fast cooling at high temperature and can achieve 180~-25 degree temperature control continuously.
5.The cycle system is closed, there is no oil mist and water vapor, to assure the lab safety and heat transfer fluid lifetime.
6.Use copeland brand compressor, circulation pump, stable performance and reliable quality.
7.Self-diagnosis function; freezer overload protection; high pressure switch, overload relay, thermal protection device, liquid low level protection, high temperature protection and temperature fault protection.
8.control heat conducting medium temperature, Use the same kind of heat conducting in the whole heating-cooling cycle.
9.High-lift design and meet the long-distance transportation of heat conducting medium.
10.With environment friendly refrigerant R404A.
