Heat exchanger for swimming pool Behncke QWT 100-209, 25 m³/h, 209.00 kW

Behncke QWT 100-209 Pool Heat Exchanger, 25 m³/h, 209.00 kW

The Behncke heat exchanger is a high-temperature heat exchanger with a stainless steel outer shell and a welded stainless steel coil. Thanks to the use of smooth tubing, lime scale formation on the primary side is impossible, provided regular maintenance is carried out.

Using the counter-current principle during heat exchange, hot and cold water flow side-by-side without direct contact. This is achieved through specially manufactured smooth-tube coils, which can handle constant and thus virtually loss-free operating pressure. The result is maximum energy efficiency of the heat exchanger.

Frequently Asked Questions

What material is the device made of?
The casing and inner coil are made of high-quality stainless steel. The outer part is additionally protected with a special electrolytic coating and heat-resistant paint.

Is the heat exchanger suitable for saltwater pools?
The standard stainless steel version is primarily intended for fresh water. For saltwater pools or electrolysis systems, a titanium version would be needed to avoid corrosion.

How is temperature controlled?
For automatic heating control, an electronic thermostat with an external temperature sensor needs to be connected. The sensor is installed at the inlet to the heat exchanger to shut off the circulation pump once the set pool temperature is reached.
