DX Coils
What is DX Coils ?
At Katariyaa Coils, we are one of the leading manufacturers, suppliers, and exporters of high-quality DX Coils. DX Coils are also called Direct Expansion Coils, highly efficient heat exchangers in a wide range of HVAC systems. These nozzles have been designed to cool the air or any other mediums with rapidity and efficiency by allowing the refrigerant to expand directly inside the coil, thus absorbing heat from them.
