Features of Cooling 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.
• High-lift design and meet the long-distance transportation of heat conducting medium.
