상품 소개

The cleanroom recirculation air unit draws room return air through a washable prefilter, passes it across an optional chilled-water coil and drives it through a HEPA or ULPA final filter. Fan, coil, condensate tray and controls are contained in a serviceable vertical cabinet, reducing the duct length required for a local clean zone. Temperature sensors can modulate the coil valve independently of EC fan speed so thermal load and cleanliness airflow are addressed separately. Supply may discharge through a front diffuser or connect to a short ceiling plenum serving adjacent work areas.

주요 기능

A return grille and prefilter capture coarse loading before it reaches the cooling coil and final filter.

The optional chilled-water coil removes local sensible heat without sending all recirculated air back to a remote AHU.

Separate EC fan and valve control allows airflow volume and temperature response to be tuned independently.

A sloped stainless condensate tray provides a defined drainage path beneath the cooling section.

고객 제품 관심사

High recirculation rates and concentrated equipment heat can overload distant ductwork even when the central make-up air system is correctly sized.

Long return-air paths consume fan energy and leave temperature gradients between process bays.The local RCU recycles room air close to the load and shortens the high-volume airflow path.

Process heat rises while the required clean-air volume remains constant.Independent chilled-water valve modulation adjusts cooling without unnecessarily changing the filtration airflow.

Condensation below a cooling coil creates a hygiene and leakage risk inside the cleanroom envelope.A sloped stainless tray and trapped drain connection collect condensate within the service compartment.

Dust on the coil increases resistance and makes wet-surface cleaning difficult.An accessible upstream prefilter intercepts coarse particles before the coil face.
