Cooling Heating Circulator is the laboratory equipment with heating and refrigeration functions, this instrument uses a number of proprietary technology, high precision of temperature control, mainly used for biological, chemical and other fields (such as rotary evaporator, reactor, fermentation tank, calorimeter and other equipment); this instrument is highly automated and can be set according to the demand automatic heating or cooling apparatus; the accurate temperature control, heating and refrigeration functions in general, can meet the various needs of biochemical experiment.
Advantages of Refrigeration and Heating Circulators
- Wide working temperature range with cooling and heating function.
- With 2pcs of LED display controller, can show the setting temp.&actual value, and alarm value for over temperature.
- Ensure fast cooling at high temperature and can achieve temperature control continuously.
- The cycle system is closed, there is no oil mist and water vapor happened, so as to assure the lab safety and heat transfer fluid lifetime.
- Use Copeland brand compressor, circulation pump, stable performance and reliable quality.
- Self-diagnosis function; freezer overload protection; high pressures witch, overload relay, thermal protection device, liquid low level protection, high temperature protection and temp fault protection.
- Use the same kind of heat conducting in the whole heating-cooling cycle when control heat conducting medium temperature.
