AHU Cooling Coils for Replacement of Existing Old Cooling Coils

For running commercial and industrial HVAC systems, worn‑out AHU cooling coils often cause many practical onsite issues. Long‑time operation may bring coil corrosion, fin damage, tube leakage, reduced heat exchange performance, higher energy consumption and unstable supply air temperature inside air handling units. Instead of changing the whole AHU cabinet, replacing old cooling coils is a cost‑effective solution for most retrofit projects.

We supply custom‑built AHU cooling coils as direct replacement for existing old cooling coils from different original brands. Our replacement cooling coils cover chilled water cooling coils and DX evaporator coils for various air handling units. According to customer’s original drawings, field‑measured dimensions, tube layout, fin density and connection positions, we manufacture matching replacement coils to fit into your current AHU cabinet without large‑scale modification to your ventilation system.

These AHU replacement cooling coils adopt copper tubes with hydrophilic aluminium fins as standard configuration. Anti‑corrosion options such as epoxy coated fins or stainless steel tubes are available for coastal, high‑humidity, dust‑heavy or chemical‑exposed working conditions. Each cooling coil goes through pressure and leak test before shipment to avoid water or refrigerant leakage after site installation.

This replacement cooling coil solution fits for factory AHU, commercial building air handling units, hospital ventilation systems, warehouse HVAC and other retrofit jobs. Customers only need to provide old coil photos, key dimension data or original technical sheets, our team will confirm coil parameters and produce drop‑in AHU cooling coils for your site swap‑out work.
