Fresh air in, moisture out. DRY X dries pool spaces through ventilation—not refrigerant recirculation. Its X-flow heat exchanger crosses airstreams to reclaim heat efficiently, delivering clean, comfortable air with lower running costs than compressor units. Humidity under control while keeping the heat. Works for any pool size—new builds or retrofits in existing/older pools—with resistance to aggressive environments: chlorine, salt, UV and electrolysis pools are a perfect match.
DRY X is Microwell’s fresh-air dehumidification platform for swimming pools. Instead of cooling and reheating the same indoor air with a compressor, DRY X brings in 100% outdoor air and exhausts humid indoor air. In the X-flow heat exchanger, the two airstreams cross and transfer heat—so supply air is tempered, humidity is exported outside, and indoor air quality improves.
X-Flow is a new heat-exchange core where supply and extract cross in an “X.” Energy from the warm exhaust is transferred to the incoming fresh air while humidity is carried out of the building. No refrigerant, no compressor—just intelligent ventilation.
DUCT DRY X 1600 ECO, a plant-room solution for larger pool halls delivering fresh-air dehumidification with X-flow heat recovery and low OPEX; DUCT DRY X 1600 PRO, the same quiet precision upgraded for aggressive environments with an epoxy-protected aluminium exchanger (ideal for chlorine, salt, UV, electrolysis); and DRY X 1200 Pro — COMPACT, a room-mounted model for fast retrofits and boutique spaces, combining low noise with PRO corrosion protection. Final specifications will be revealed at launch—reserve the Project Pack or get notified first.
Outdoor air enters the unit and passes through the X-flow heat exchanger while humid air from the pool hall is extracted and driven through the exchanger in the opposite direction. As the two airstreams cross, heat transfers from the exhaust to the incoming supply, tempering the fresh air before it enters the space, and the moisture is carried away to the outside with the exhaust stream. In warm seasons a built-in bypass routes air around the exchanger for free-cooling and rapid venting when conditions allow, while an optional recirculation path can be engaged to speed up space reheat after setbacks. In practice, dehumidification scales with the absolute humidity difference multiplied by airflow, so your selected design flow determines the achievable litres-per-day at the target temperature and relative humidity.
Scope. This guidance helps you design with DRY X in projects following ASHRAE natatorium best practice and VDI 2089 (Indoor swimming pools — ventilation & dehumidification). Use alongside national/local codes, fire regulations, and architectural envelope requirements.
