First, an overview of water-cooled ultra-low temperature chillers

The water-cooled ultra-low temperature chiller combines the characteristics of many other refrigeration and heating temperature control equipment, adopts semi-hermetic screw compressor, supplemented by high-efficiency heat exchanger, adopts PLC microcomputer controller and color touch screen, so that the equipment has a compact appearance and a layout. Reasonable, easy to use and maintain. The user only needs to connect the pipeline of the chilled water system, the pipeline of the cooling water system and the required power supply, and it can be put into operation.

Application of water-cooled ultra-low temperature chiller: industrial and mining enterprises such as textile, chemical industry, petroleum, etc. provide process chilled water. This product has mature manufacturing technology and stable and reliable operation.

Second, accessories of water-cooled ultra-low temperature chiller

The circulating pump of the water-cooled ultra-low temperature chiller is suitable for the overshoot reaction of rapid exothermic and heat absorption in a short time, and the magnetic drive non-leakage pump with high temperature and low temperature resistance reduces the risk of leakage. At the same time, it has a series of advantages such as low noise, large flow, long lift, large flow rate, and low calorific value.

The compressors of water-cooled ultra-low temperature chillers mainly use brand compressors to improve product quality and ensure after-sales service. Through the single-machine self-cascading refrigeration process, the compressor can work well regardless of high temperature or low temperature.

The water-cooled ultra-low temperature chiller adopts the brand electronic expansion valve to accurately control the number of steps of the stepper motor, so as to accurately control the opening of the electronic expansion valve, so as to achieve the purpose of accurately controlling the refrigerant evaporation of the compressor.

Some equipments are equipped with pressure gauges, according to which the status of the compressor can be judged. When the water-cooled ultra-low temperature chiller is actually used, the pressure value is different according to the different ambient temperature. If the pressure gauge indicates less than 0.7Mpa during standby, it means that there may be refrigerant leakage in the system. Please check the leakage point in time to ensure the normal operation of the equipment.

When selecting thermal insulation materials, the temperature range of the equipment should be considered first, and flame retardant materials must be selected. The suitable temperature range of the thermal insulation material should include the temperature range of the equipment, with a margin greater than 30°C. If the user ignores this problem, it may cause a fire. The thermal insulation material package should be sufficient, otherwise it will cause the possibility that the equipment control will not achieve the expected effect.
