Application characteristics:
A circulation device capable of providing a heat source or a cold source. It has a wide range of work and can be used in pharmaceutical, chemical, biological and other industries to provide heat and cold sources for reactors and tanks.
● wide temperature control range: - 20 ℃ ~ 200 ℃.
● precooling system, refrigeration system and heating system can be used in combination.
● rapid heating or cooling.
● large cooling rate, which can be forced to cool quickly.
● totally closed circulation system, heat conducting fluid is not easy to volatilize and oxidize at high temperature; It is not easy to be affected by environmental conditions at low temperature and can prolong the service life of the heat transfer fluid.
● fully brazed plate heat exchanger is adopted for refrigeration heat exchanger, which occupies small space and has high heat exchange efficiency.
● liquid level display function to monitor liquid level in real time to avoid lack of heat carrying fluid.
● over temperature protection, leakage protection, overcurrent protection and other protection functions to fully ensure the safety of users and equipment.
● according to the user's requirements, air cooling and water cooling can be provided.
● divided into 3 systems: refrigeration system, heating system, pre cooling system, the three systems can be used continuously or separately.
● rapid heating and cooling to continuously raise and fall temperatures.
● wide temperature control range, no need to change conductive medium throughout, less conductive medium consumed.
● fully closed circulatory system, thermally conductive fluid is not volatile and oxidized at high temperature, and moisture in air is not easily inhaled at low temperature, which can extend the lifespan of thermally conductive fluid.
● high temperature cooling, refrigeration function, in which direct cooling may be obtained from elevated temperatures (e.g., direct cooling may be obtained from 200 ℃).
● the refrigeration heat exchanger uses a fully brazing plate heat exchanger, which occupies little space and has high heat exchange efficiency.
● the level display function to monitor the level at any time, avoiding fluid deficit.
● multiple protective functions such as high temperature cut-off, acute stop, time delay, electric leakage, over current and over heating, which sufficiently guarantee the safety of use.
● condensation, pre cooling for air cooling, conserve water resources.
Explosion-proof electrical: additional $400.
110V voltage requires an additional $200.
Application:
● temperature control of double-layer and three-layer reactors in chemical, pharmaceutical and biological fields.
● temperature control in material testing.
● temperature control of distillation system.
● temperature change simulation control during the process.
● thermostatic control system.
● temperature control of semiconductor equipment.
● temperature control of thermal test platform.

Precautions for DOVMXtech-GDX series closed refrigeration heating cycle device:
To ensure the cooling efficiency of the system, in addition to ensuring that the ambient air around the instrument is clean, any dust on the condenser surface must be regularly inspected and cleaned. Please follow the following steps:
① Confirm that the power connector of the equipment has been unplugged.
② Remove the two screws on the lower side of the air intake ventilation net cover of the equipment, then pull the net cover down slightly, and then remove it.
③ Use soft brush or other similar tools to check and clean the dust on the surface of the net cover and condenser.
◆ do not touch the condenser fins with your hands to avoid scratching your hands!
④ After cleaning, install the ventilation net cover and tighten the screws.
We're sorry if we didn't respond in time.
Each equipment will undergo many strict inspections before delivery and transportation to ensure that it is intact. All electrical parts are warranted for one year (except for vacuum pumps and glassware). We have provided double copies for easily damaged items.
