Введение продукции

The fresh-air dehumidification unit treats the ventilation and replacement air that creates the largest seasonal latent load in many cleanrooms. A prefilter and cooling coil remove heat and bulk moisture, the desiccant section lowers the dew point, and recovered condenser or reactivation heat tempers the leaving air. Weather-resistant louvers, drainable coil sections and pressure-capable fans allow the unit to supply dry make-up air without burdening the recirculation AHU.

Основные характеристики

A full outdoor-air intake path isolates ventilation moisture before it reaches the cleanroom recirculation system.

Mechanical cooling handles high-temperature bulk condensation while the desiccant stage addresses the remaining vapor load.

Recovered refrigeration heat can temper overcooled air and reduce separate reheat energy.

Low-leakage dampers and variable-speed supply control maintain the scheduled make-up airflow as filters load.

Обеспокоенность клиентов продуктами

Untreated outdoor air can overwhelm the sensible and latent capacity of a cleanroom recirculation unit, especially during humid weather.

Summer ventilation air drives room humidity above the process limit despite adequate recirculation cooling.The dedicated unit removes outdoor latent load before the make-up air joins the cleanroom supply stream.

Deep cooling alone produces air that is dry enough but too cold for direct delivery.Recovered condenser heat or a controlled heating coil resets the dry air to the required supply temperature.

A dirty intake filter reduces make-up airflow and weakens cleanroom positive pressure.Differential-pressure monitoring and variable-speed fan control preserve scheduled airflow and signal filter service.

Rain and wind-driven moisture enter through an exposed outside-air opening.A weather louver, drainable intake plenum and sloped stainless drain pan separate liquid water before the treatment sections.
