The DanX XD & HP compact units are energy and cost-efficient solutions that combine dehumidification, temperature control, fresh air supply and ventilation in hotel pools, wellness centres and private pools with focus on low energy consumption.

DanX XD:
With double cross-flow heat exchanger.

DanX HP:
With double cross-flow heat exchanger and heat pump.

All components of the DanX units ensure high capacity and a long service life. The system allows up to 100 % outdoor air supply. Double cross flow heat exchangers deliver up to 95 % heat recovery combined with low-energy EC fan motors. High-efficiency compressors ensure the lowest possible operating costs.

DanX 2 HP
DanX HP Daytime: Partial recirculation with heating, 2-stage heat recovery and dehumidification with outside air and heat pump (HP model). To minimise pressure loss, only some of the humid air is conducted through the heat exchanger for evaporation. If dehumidification is insufficient, the proportion of dry outside air is increased automatically.

Installation costs are kept to an absolute minimum. The ultra-compact units are delivered fully assembled, with built-in after heating coil and control system. Convenient top or side connections ensure easy access to ducts.

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.
