Heat exchanger for swimming pool Behncke QWT 100-140, 20 m³/h, 140.00 kW

Behncke QWT 100-140 Pool Heat Exchanger, 20 m³/h, 140.00 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 a smooth tube, limescale formation on the primary side is impossible, provided regular maintenance is carried out.

When using the counter-flow principle during heat exchange, hot and cold water flow side-by-side without coming into contact. This is achieved by specially manufactured smooth-tube coils, which can handle constant and therefore virtually lossless 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 internal 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 designed for fresh water. For saltwater pools or electrolysis systems, a titanium version will be required to prevent corrosion.

How is temperature controlled?
For automatic heating control, an electronic thermostat with an external temperature sensor is required. The sensor is installed at the heat exchanger inlet to switch off the circulation pump when the set pool temperature is reached.
