HRHC Series Refrigeration Heating Chiller, Circulator Heater, -10°C~-80°C to +200°C, 30~50L

HRHC Series Refrigeration Heating Chiller, Circulator Heater

HRHC Series high and low temperature Refrigeration Heating Chiller, Circulator Heater is also called the high and low temperature circulation pump. The heating and cooling integrated machine is a high and low temperature circulation integrated machine, which is specially used for the temperature rise and fall of the reactor.

The heat-conducting medium of the entire circulation system is a fully-closed cycle. The circulation system has a liquid expansion container. The expansion container and the liquid circulation are independent systems. The expansion container does not participate in the liquid circulation, but is mechanically connected. Even in the case of high temperature operation, the heat conducting medium in the expansion vessel will not be higher than 50 degrees.

The entire liquid cycle is a closed system. There is no absorption of water vapor at low temperatures and no oil mist at high temperatures, which increases the service life of the heat transfer oil. The same equipment and the same heat transfer medium can achieve continuous temperature control from -95 degrees to 350 degrees. The range of cooling capacity is 1KW ~ 100KW.

HRHC normal series                                                         HRHC explosion-proof series (EX)

Features

1. Equipped with a heating and cooling integrated container, the heat exchange area is large, the rate of heating and cooling is fast, and the demand for heat transfer oil is relatively small.
2. It can achieve continuous temperature rise and fall, using compressor technology running under high temperature and high pressure, the compressor refrigeration can be directly turned on from 350 degrees, which greatly provides the cooling rate, saving test time and energy.
3. The entire cycle is closed. There is no volatilization of oil mist at high temperatures, and the heat transfer oil is not easy to be oxidized and browned. At low temperatures, it is difficult to absorb water vapor in the air. The service life of the heat transfer oil is extended.
4. This equipment has self-diagnostic function, freezer overload protection, high-pressure pressure switch, overload relay, thermal protection high-temperature protection device of high temperature heating cycle system and other safety guarantee functions, fully guaranteeing the safety of use;
5. Temperature adaptive control, adaptive control system in the control process (such as chemical reaction process), continuously adjust the PID parameters to give the process the best control temperature and response time, this process is through effective multi-directional The measurement of temperature, temperature change and the rate of temperature change are achieved.
6. It has the function of correcting the external and internal circulation temperature probe PT100.
7. Using CFC and HCFE-free refrigerants.
8. Accurately control the speed of chemical reactions.
9. Liquid circulation pipeline, the heating pipe is made of high quality industrial grade seamless 304 stainless steel with a thickness of 3.0mm, which is not a decorative pipe.
10. Refrigeration system adopts American Copeland compressor, French Tecumseh, high temperature resistant circulating pump, stable performance and reliable quality.
11. This unit uses solid-state relays without sparks and noise. Long life, safe and reliable!
12. It can display temperature set value and actual value at the same time, and over temperature alarm value.
13. The filling liquid is efficient and fast, and the filling is simple.
14. Ensure rapid temperature reduction under high temperature conditions; continuous temperature control from 350 degrees to -95 degrees can be achieved to save test production time.
15. liquid circulation pipeline, heating pipe using high-quality industrial grade seamless 304 stainless steel with a thickness of 3.0mm, is not an ordinary decorative pipe.
16. High-lift design to meet long-distance transportation of heat-conducting media.
17. The circulating connection is connected by 304 stainless steel wire hose!
