REV pool heat exchangers achieve very high heat exchange coefficient thanks to the 3-pass tube bundle.
The HEXONIC REV pool heat exchanger is designed mainly for swimming pool installations, where the main design priority is improved heat exchange performance. This is achieved through a unique 3-pass tube bundle design, which enables better utilization of source thermal power and improves overall heat exchange conditions.
Additionally, thanks to the short path of pool water through the exchanger, flow speed remains high. Corrugated tubes increase flow turbulence, which further intensifies heat transfer and helps reduce sediment accumulation. REV heat exchangers are available in two material versions - stainless steel and titanium - and work very well with heat pumps, solar panels, and standard heat sources such as gas-fired boilers.
Key Features
- Unique 3-pass tube bundle: The 3-pass design allows better utilization of source thermal power and helps achieve very high heat exchange coefficient.
- Improved heat transfer: Corrugated tubes create turbulent flow, which intensifies heat exchange.
- High pool-water flow speed: The short path of the heated medium through the exchanger keeps flow speed high.
- Stainless steel version for treated water: The stainless steel make is appropriate for pools with treated water.
- Resistance to aggressive pool chemicals: The exchanger is resistant to aggressive substances in pool water, such as fluorine and chlorine.
- Titanium option available: The REV TI version is offered for applications requiring salt-water resistance.
- Low flow pressure drop on shell side: The live page lists low pressure drop on the pool-water side as a key feature.
- Excellent compatibility with renewable and standard heat sources: REV is described as perfect for operating with heat pumps and solar panels, as well as gas-fired boilers.

How does the REV exchanger work
The heating medium passes three times through the tubes, which significantly improves heat exchange conditions, as hot medium remains longer in the exchanger. The corrugated tubes cause turbulent flow, which intensifies heat exchange and reduces sediment formation.

Frequently Asked Questions
The HEXONIC REV heat exchanger is intended mainly for swimming pool installations. It is designed to improve heat exchange conditions in pool-heating systems by using a 3-pass tube bundle and corrugated tubes.
The main advantage is the unique 3-pass tube bundle, which allows better utilization of source thermal power and helps achieve a very high heat exchange coefficient. The short pool-water path also keeps flow speed high, further improving performance.
The standard REV is available in stainless steel and is appropriate for treated pool water. For salt-water resistance, HEXONIC offers the REV TI version in titanium.
The REV works very well with heat pumps, solar panels, and standard heat sources such as gas-fired boilers.
