Multi-function alarm system and safety function, use plate heat exchanger, tube type heater to increase heating and cooling rate.
7-inch and 10-inch color TFT touch screen graphics display, use magnetic drive pump, no re-seal leakage problem.
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.
Impact and Solution of Excess Exhaust Temperature of Industrial Chiller Units
Industrial water chiller compressor exhaust temperature determines whether the equipment can stably and efficiently run. The common problem of compressor is excess exhaust temperature. Once the situation appears, it is easy to make industrial chiller high pressure and high temperature, overload, reduced working efficiency and poor industrial water chiller compressor refrigerating capacity. It can also lead to other problems. So how to reduce the exhaust temperature of industrial water chillers and cool the compressor, we are the experts to develop water chiller refrigeration system 320/420 w / 430 w experts, so today we will recommend a few solutions for you:
Increase cooling water flow and heat ventilation of water tank and water tower.
Air-cooled water tank of industrial cold water machine and cooling water in industrial cooling towers are to cool the condenser and transfer heat which can take away the heat generated by the compressor work. If you can guarantee the cooling water flow rate and air cooling industry cold water machine water tanks, water chiller water tower cooling ventilation ability, you will keep cooling water temperature to within the limits defined, so as to maximize the cool the compressor.
Reduce the exhaust temperature of the refrigeration compressor directly.
You can start from decreasing compression ratio and the load of the compressor. Lower compression ratio will make compressor low efficient, but it can solve the problem of excess exhaust temperature of compressor.
