Cooling Coils Replacement for Dry Cooler

Stainless Steel Tube (304 / 316L) Replacement Coils

Full SS tube + coated aluminum fin

For corrosive media: brine, chemical wastewater, palm oil plant process fluid, seafood processing glycol

Dry coolers widely used for industrial fluid cooling: glycol, process water, refrigerant, engine jacket water, solar thermal, chiller free cooling, data center CDU, and HVAC systems. Replacement coils are direct-fit spare cores to swap damaged, fouled, corroded original assemblies without replacing the entire dry cooler unit.

Core Function of Dry Cooler Coil

Process hot liquid flows inside seamless metal tubes; axial fans push ambient air across external fin surfaces. Heat transfers from the fluid to outdoor air, lowering fluid temperature before recirculation.

If coil fails: high fluid supply temperature, system overheat, pump overloading, sharp energy rise, forced production downtime.

Step-by-Step Replacement Installation Procedure

Drain all process fluid from the dry cooler loop, isolate unit with shut-off valves.

Disconnect fluid inlet/outlet flanges or threaded connections; remove fan assembly if blocking coil extraction.

Unbolt old coil frame, lift and remove damaged coil core.

Clean dry cooler internal frame, fan guards, drain residual sludge and scale.

Place new replacement coil into original mounting position, align flanges perfectly.

Braze or flange connect fluid pipelines, perform nitrogen pressure hold leak test (1.5× working pressure).

Reinstall fans, restore fluid piping, refill system with clean process fluid.

Start circulation pump and fans, test running data: monitor fluid inlet/outlet temperature, check for air flow dead zones and abnormal pressure drop.
