The air conditioning heat exchanger [SK Water Coil] is an air conditioning heat exchanger installed inside air conditioning units that generates warm or cool air using water (cold or hot water) as the heat source. Since the air conditioning unit maintains airtightness, the air conditioning heat exchanger is a non-airtight type that only requires a fixed case. Depending on the region, it is also possible to switch to the [SK Brine Coil], which uses antifreeze as the heat source. Generally, copper pipes are used, but if high pressure, high-temperature water, or corrosion resistance is a priority, stainless steel can be used. When updating the heat exchanger in an existing air conditioning unit, even if changing to equivalent products or materials, you can verify the thermal load through capacity calculations if you provide the design conditions. For heat exchangers in air conditioning units and when updating existing products, please consult "Boundary River Industry for Heat Exchangers."

It is capable of producing cold air below zero degrees Celsius and is used as a heat exchanger for cooling devices aimed at dehumidification, drying, and the refrigeration and freezing preservation of food. Additionally, in cold regions where temperatures drop below freezing, the heat exchange tubes of the heat exchanger may burst and leak due to freezing. The cooling heat exchanger "SK Brine Coil" uses brine (antifreeze), which prevents freezing. *Please refer to the notes below.* *Note 1: The shape is the same as the heat exchangers for generating warm and cold air, the "SK Water Coil" for warm air and the "Heat Medium Oil Coil." Note 2: Choose a brine (antifreeze) that does not freeze at the minimum temperature and manage its concentration. Note 3: Using below the manufacturer's specified minimum concentration may lead to the growth of moss and a decrease in the heat exchanger's performance, so please be cautious. Note 4: Some antifreezes can corrode the heat exchange tubes. Please be careful when using them.* For more details, please contact us or download the catalog.
