Cold Water Chiller

A: Why are the compressors and evaporators of industrial water chillers wrapped with thick insulation cotton? During the manufacturing process, workers install insulation cotton on the compressor, evaporator, and piping of packaged water chillers. This is a very important step, as it effectively reduces cooling loss and prevents condensation.

A: When Kansa industrial chillers maintain a water temperature above 7°C, is it sometimes necessary to add antifreeze?
Firstly, when the unit is used in northern regions, the ambient temperature may remain below zero for extended periods. If the chiller is shut down, the water system and heat exchanger may freeze and damage.
Secondly, automotive antifreeze not only has a low freezing point but also prevents rust and corrosion. This greatly ensures efficient heat exchange and stable operation of the unit.
Finally, antifreeze prevents scale buildup. Scale buildup on water system components and heat exchangers reduces heat exchange efficiency, affecting the unit's cooling performance. Automotive antifreeze is made from distilled water and contains anti-scaling additives to prevent scale formation.

A: The answer is 60°C. The highest ambient temperature for a standard Kansa industrial chiller unit is 45°C, while our high-temperature unit can operate normally in an environment of 60°C. This is because our high-temperature unit uses a special compressor, a special refrigerant, and Kansa Refrigeration's PID liquid injection compressor balancing technology, allowing our unit to function normally at such high temperatures.
