HNS - Pool Dehumidification Air Handling Units
The HNS series is a purpose-engineered pool dehumidification air handling unit designed to maintain indoor swimming pool environments at the 40–64% relative humidity range required by VDI 2089/1 — preventing condensation, corrosion, fungal growth, and structural damage caused by the high evaporation rates of indoor pool water surfaces. Built with a modular, double-skinned 50mm rockwool panel construction, scroll compressors, R407C refrigerant, and heat-pipe heat recovery coils, the HNS series delivers powerful dehumidification with maximum energy efficiency.
- We guarantee EU-standard quality.
- Count on rapid, reliable global delivery.
- Backed by 24 years of expertise.
Areas of Use
The HNS series is the definitive air conditioning and dehumidification solution for indoor swimming pool environments, where uncontrolled humidity causes progressive structural damage, corrosion, mold growth, and occupant discomfort. Its specialized design addresses the unique challenges of pool hall environments that no standard AHU can adequately handle. Deploy these specialized pool dehumidification units confidently in:
- Indoor swimming pools in hotels, resorts, and leisure facilities
- Public and municipal swimming pool halls and aquatic centers
- Residential and private indoor pool environments
- Sports academies, fitness centers, and health clubs with indoor pools
- Spa facilities, hydrotherapy centers, and therapeutic pool environments
Key Features & Specifications
Purpose-Built Pool Dehumidification Design: The HNS series is specifically engineered to control the high humidity levels generated by indoor swimming pools — maintaining the 40–64% relative humidity range required by VDI 2089/1 to prevent condensation on windows and walls, corrosion of building components, fungal growth, and swimmer discomfort.
High-Efficiency Scroll Compressors: All HNS units use scroll-type compressors — the most reliable and efficient compressor technology available for dehumidification applications. All electrical components are fully protected against high temperature and overcurrent for maximum operational safety and longevity.
Heat-Pipe Type Heat Recovery Coil: Each unit is equipped with a heat-pipe heat recovery coil that captures and re-uses the energy extracted during dehumidification to pre-heat the fresh air supply — significantly increasing system energy efficiency and reducing operating costs compared to conventional dehumidification systems.
Modular Double-Skin Panel Construction: The HNS is manufactured as a modular unit with 50mm thick double-skin rockwool insulated panels and an electrostatic oven-painted aluminum profile frame — providing excellent thermal and acoustic insulation, structural rigidity, and long-term corrosion resistance in the persistently humid pool hall environment.
G4 Filters in Suction & Blowing Lines: Cassette-type G4 filters are installed in both the suction and blowing air lines, protecting internal components from airborne contaminants and chlorine particles common in pool hall environments — with easy cassette removal for maintenance without tools.
R407C Refrigerant System: The dehumidification circuit uses R407C refrigerant — a proven, widely serviceable refrigerant with well-established supply chains and low environmental impact — ensuring the system remains fully supportable throughout its operational lifetime.
Flexible Transport & On-Site Assembly: The modular three-cell structure can be shipped fully assembled, partially assembled cell-by-cell, or fully disassembled and assembled on-site — providing maximum flexibility for access-constrained buildings and difficult installation locations.
