Our designers and Technicians take pride in living up to the motto.
A Mark of Quality: three types of Coils
Direct Expansion (DX) Coil
Direct Expansion (DX) coils effectively cool the area by absorbing heat from the air directly using refrigerant. We have designed our DX coils to operate at high pressures (up to 600 PSI) and with low energy consumption using common refrigerants like R22, R134a, and R407C.
Chilled Water Coil
These coils cool air in HVAC systems by moving chilled water via pipes. Our coils are constructed from sturdy materials like copper and aluminum to effectively withstand high pressures, and they include counter-flow heat exchange for optimal heat transmission.
Hot Water Coil
Hot water coils heat air by passing it over hot water pipes. Our hot water coils, which are composed of corrosion-resistant materials like copper and stainless steel, can tolerate high temperatures and provide dependable and economical heating.

FAQ's
Heat exchangers transfer thermal energy between two fluids, usually air and water or refrigerant, without mixing them. They are used for both heating and cooling purposes in air handling units and fan coil systems.
DX cooling coils (direct expansion) use a refrigerant that absorbs heat directly from the air passing over the coil. This method ensures faster and more efficient cooling compared to other systems.
A chilled water coil uses cold water from a central chiller plant. On the other hand, a DX cooling coil uses refrigerant for direct cooling. Chilled water systems are common in large buildings, whereas DX systems are used in smaller or isolated zones.
