Full airtight system, extended thermal conductivity liquid life, very wide temperature range, no need to change liquid media.
Ultra-high temperature cooling technology can be cooled directly from 300 degrees of high temperature.
The principle and the function has many advantages to using staff: because only expansion of cavity in the body heat conduction medium contact with oxygen in the air (and expansion tank temperature at room temperature to 60 degrees), can achieve lower heat conduction medium absorbed by oxidation and the risk of air moisture.
No heat conduction medium evaporates at high temperature, and it can be achieved -80 ~ 190 degrees, -70 ~ 220 degrees, -88 ~ 170 degrees, -55 ~ 250 degrees, -30 ~ 300 degree continuous temperature control without pressurization.

Adopt full closed pipe design, adopt high efficiency plate heat exchanger, reducing the demand for heat conduction liquid, improve the heat utilization rate of the system, reach the rapid lifting temperature.Thermal conductive medium in a closed system, with a container, expand the heat-conducting medium not participate in circulation in the container, whether high or low temperatures, expansion tank temperature to room temperature to 60 degrees, can reduce the heat conduction medium in running the risk of absorbing the moisture and volatile.

Lab water chillers, as the name implies, are mainly used in colleges and universities, scientific research and laboratories. Specially for the cooling of small laboratory equipment such as spectrometer, mass spectrometer, viscometer, rotation, fermentation device, a rotary evaporation apparatus, etc. to make them work under the suitable working temperature.

Could them only be used in this way? In fact, the lab water chillers are also called small chillers. It can also be used for cooling with small instruments or small power equipment. For example:

1. Vacuum pump and medical equipment: molecular pump, diffusion pump, cooling blanket, X-ray machine, nuclear magnetic resonance, accelerator;

2. Industrial equipment and other: laser equipment, vacuum coating equipment, biological pharmacy, mold, machine tool, vacuum furnace, welding machine, reaction kettle.

3. Matched small vacuum pumps, such as molecular pumps, oil and gas recovery pumps, small roots pumps, rotary disc pumps, slide valve pumps, etc. It has the advantages of convenient connection, simple operation, stable temperature, and saving water and electricity, providing a stable temperature environment for the vacuum equipment, and providing the operating efficiency of the equipment.
