for swimming pool air management.


The DanX units are superior solutions for controlling the relative humidity and fresh air supply in swimming pool halls.

A one or two stage heat recovery system and a specially-made control system provide energy-efficient and cost-effective control of the swimming pool hall environment.

The DanX units are designed to endure the aggressive environment encountered in swimming pool halls. A robust, optionally powder-coated, framework and a cross flow heat exchanger of anodized and epoxy-coated aluminium protect the DanX unit against corrosion.

The long service life of the DanX units results in long term economic gains and contributes to a low total cost of ownership.

The DanX units are available in different sizes and with a double heat exchanger, a heat pump and cross flow heat exchanger, a heat exchanger and reversible heat pump, a cross flow heat exchanger or a heat pump.

All DanX systems are supplied with a control package, which takes demand management to a new level. Based on years of experience and on-going development, the control strategy has been optimized specifically for Dantherm swimming pool units. Read more about the user friendly DanX Control System.
