Introducción del producto

This RCU adds documented make-up and exhaust connections to a 1000 m³/h nominal local recirculation path. Up to 500 m³/h of make-up air can be introduced while an H14 filter protects the supply, and Modbus RTU provides control-system communication. The model is intended for positive-pressure rooms that need both local circulation and a measured fresh-air path.

Características clave

Dedicated fresh-air path

The make-up connection introduces controlled outside supply without replacing the local recirculation loop.

Pressure-balance support

Make-up and exhaust connections allow the room airflow balance to be coordinated around a pressure target.

Digital integration

Modbus RTU supports connection to a supervisory cleanroom control system.

Applications

Recommended for positive-pressure pharmaceutical and precision-production rooms that need local filtered recirculation plus controlled fresh air. Exhaust and leakage must be included in the final mass balance.

Solutions for Your Application

Local recirculation alone cannot maintain room pressure or ventilation air.Use the make-up connection to add up to 500 m³/h while retaining the 1000 m³/h recirculation duty.

Independent fan controls can drift apart.Integrate the unit through Modbus RTU and commission recirculation, make-up and exhaust as one airflow balance.

Opciones disponibles

Define make-up and exhaust connection sizes, H14 seal, Modbus addressing and access arrangement. Final flows should be set from the room pressure cascade.
