Chemical Medium Temperature Control Chiller
APPLICATIONS
This CHILLER can directly introduce chemical media and accurately control the temperature, as a preheating and precooling temperature control for the medium before the chemical reaction; chemical media such as hydrofluoric acid, sulfuric acid, ammonia, nitric acid, ozone water, hydrochloric acid, sodium hydroxide, etc., need to confirm whether the concentration and temperature are met.

WORKING PRINCIPLE

Ultra high temperature cooling technology can directly cool from a high temperature of 300℃[because only the heat transfer medium in the expansion chamber contacts with oxygen in the air (and the temperature of the expansion tank is between normal temperature and 60℃), which can reduce the risk of heat transfer medium being oxidized and absorbing water in the air. At high temperature, no heat conducting medium evaporates, and continuous temperature control of – 80℃ ~ 190℃, – 70℃ ~ 220℃, – 88℃ ~ 170℃, – 55℃ ~ 250℃ and – 30℃ ~ 300℃ can be realized without pressurization.
Color Screen Control

1. Displays all the kind of process control temperatures.
2. Shows the liquid level of the heat conducting medium in the expansion vessel.
3. Shows indication for refrigeration system working.
4. Shows indication for heater working.
5. Shows indication for circulation pump working.
6. Displays the temp. control ( materials temp. control pattern, heat conducting medium temp. control ).
7. The temp. upper limit, lower limit control can be set.
8. The temp. difference between jacket & reactor material can be set.
9. Shows the alarm to add the liquid when it is empty.
10. The refrigeration compressor can be set to operate manuallyor automatically.
