The ST series condensing coil exerts its maximum heat exchanging performance as it is designed to ensure that the air flow and coolant from the coolant spray system can be spread evenly across the coil. The condensing coil is subjected to 2 rounds of pressure tests after a hot dip galvanizing treatment. Each part of the coil is supported by frames such as angles and channels, and all the parts of the coil is hot dip galvanized to ensure strong durability. The ST series high efficiency condensing coil is hot dip galvanized after assembling special custom-made carbon steel pipes for pressure service, which ensures outstanding corrosion resistance and high efficiency thermal conductivity. This product is certified through strict quality and performance tests performed by the refrigeration and air conditioning team at the Korea Institute of Industrial Technology and Korean Agency for Technology and Standards).
