Введение продукции

The dry room air handling unit removes water vapor beyond the practical range of cooling coils by passing process air through a continuously regenerated desiccant rotor. A pre-cooling stage reduces incoming moisture load, the rotor performs deep drying, and post-cooling controls supply temperature. A separate heated regeneration airstream removes captured moisture from the rotor and discharges it outdoors. Recirculating most of the dry-room air limits the outdoor moisture load, while sealed casing and low-leakage dampers protect the achieved dew point.

Основные характеристики

A desiccant rotor removes vapor at dew points where condensation-based cooling becomes inefficient.

Separated process and regeneration air paths prevent wet regeneration exhaust from mixing with dry supply air.

Pre-cooling and sensible post-cooling reduce rotor load and set the final supply temperature.

High dry-air recirculation minimizes the quantity of humid outdoor air that requires deep treatment.

Обеспокоенность клиентов продуктами

Ultra-low humidity is easily lost through casing leakage, door infiltration, wet regeneration carryover and moisture released by process materials.

A chilled-water coil cannot reach the required dry-room dew point.The desiccant rotor adsorbs remaining vapor after the air is precooled.

Regeneration exhaust leaks into the dry process airstream.Sealed rotor sectors, pressure control and purge arrangements limit cross-stream carryover.

Opening personnel or material doors causes slow humidity recovery.Sufficient recirculation airflow and controlled dry-air make-up remove the infiltration moisture load.

Reactivation heat dominates system energy use.Purge optimization, heat recovery and the appropriate steam, gas, electric or heat-pump source reduce regeneration demand.
