Product Details

FEATURES:

1. Wide working temperature range with cooling and heating function, temperature range: -45~250℃.
2. With 2pcs of LED display controller, can show the setting temperature & actual value, and alarm value for overtemperature.
3. Efficient fast, simple topping up liquid.
4. Ensure fast cooling at high temperature and can achieve 250℃~-55℃ temperature control continuously.
5. 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.
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. Use the same kind of heat conducting in the whole heating-cooling cycle when control heat conducting medium temperature.
9. High-lift design and meet the long-distance transportation of heat conducting medium.
