The Helios Fans KWL HBX 250 WW R HygroBox is a high-efficiency humidification unit designed for active air treatment in apartments and shared indoor spaces. Built for installation or retrofit into ventilation and air-conditioning systems, it uses natural evaporation to maintain a stable indoor humidity level between 40% and 60% relative humidity.
The integrated warm water heating coil preheats incoming air to optimize evaporation performance. Air is humidified as it passes over a rotating aluminium blade evaporator, which sits inside a stainless steel water tray. The system draws water directly from the drinking water supply and maintains a consistent fill level through automatic regulation.
An advanced electronic control unit ensures safe and efficient operation, with real-time monitoring and control via a TFT touchscreen or building automation systems through Modbus. Hygiene is ensured through continuous UV‑C disinfection and automatic water replacement, while an integrated reverse osmosis unit prevents limescale buildup.
Constructed from white powder-coated galvanized steel, the unit is durable and compact, with right-hand air supply configuration. The KWL HBX 250 WW R is a robust solution for consistent and hygienic humidity control in modern air handling systems
