HITC series — variable frequency oil chiller

TOBEL self-developed oil chiller utilizes forced air-conditioning cooling to control the oil temperature of mechanical equipment at constant temperature(such as hydraulic oil and lubricating oil).

Low temperature and low pressure liquid refrigerant exchanges heat with the oil in the evaporator, and evaporates into low temperature and low pressure gas. The temperature of refrigerant remains unchanged during the evaporation process.Then gas refrigerant is compressed by the compressor and compressed into high temperature and high pressure gas. When gas refrigerant enters the condenser, it exchanges heat with the indoor air. The refrigerant releases heat and comes into high temperature and high pressure liquid, and goes into the expansion valve.Throttling is a rapid cooling process, the refrigerant returns to low temperature and low pressure liquid. This cycle is continuous, so the oil can be continuously cooled.

product details

Characteristics

Efficient and energy-saving : saving 30% electricity compared to fixed frequency units
Accurate temperature control : The temperature of the chilled water is controlled within plus or minus 0.1 degrees , meeting the requirements of high - precision temperature control .
Rapid cooling : Compared to fixed frequency units , the cooling time is increased by 50%
Extend the lifespan of the compressor: the variable frequency host operates mostly under low - speed load , which has less wear on the compressor.
Low starting current : the starting current is small and has little interference with the power grid
