Duratech DURAPRO-12 R32 Heat Exchanger

This genuine Duratech heat exchanger is a replacement component for DURAPRO-12 heat pump units running R32 refrigerant. The heat exchanger is where the transfer of thermal energy to your pool water actually takes place, making it one of the most critical parts of the system.

How the Heat Exchanger Works

Within a heat pump, the heat exchanger serves as the point where hot refrigerant gas releases its thermal energy into the pool water circuit. The refrigerant flows through one set of channels while pool water passes through another, with the heat moving from the warmer refrigerant to the cooler water. The two fluids never mix, ensuring your pool water remains uncontaminated while efficiently absorbing the captured heat.

Why Heat Exchangers Fail

Over time, heat exchangers can develop problems due to the demanding environment they operate in. Corrosion from chemically treated pool water, scale buildup from hard water, physical damage, or manufacturing defects can all lead to reduced efficiency or outright failure. Symptoms include the heat pump running but not heating the water effectively, visible leaks around the unit, or refrigerant pressure faults if internal damage has occurred.

R32 Compatibility

This heat exchanger is specifically designed for DURAPRO-12 units using R32 refrigerant. Components in R32 systems are optimised for the characteristics of this refrigerant, so matching parts correctly is essential for safe and efficient operation.

Professional Installation Recommended

Replacing a heat exchanger involves working with the refrigerant circuit and pool water connections. A qualified engineer with appropriate F-Gas certification should carry out the work to ensure the system is safely evacuated, the new exchanger correctly installed, and the unit recharged and tested.
