iCM500

Fume Cupboard Controller

Product description

Variable microcontroller system for controlling and monitoring the exhaust air volume flow or the face velocity of fume cupboards as a function of the vertical and horizontal sash position.

The integrated function monitoring according to DIN EN 14175-6 provides maximum safety for the laboratory staff. An optical and acoustic alarm on the display of the iCM500 are triggered if the value falls below the respective setpoint value for exhaust air. The standard model is suitable for all types of fume cupboards and extractor systems. The standard model is delivered ex-factory with an airflow sensor.

Functional description

The fume cupboard controller iCM500 constantly compares the actual values determined by the sensors used and controls the preset nominal value quickly and precisely.

The advanced extract air demand request immediately calculates the demand for extract air and provides this directly as a setpoint for the central extract air system. This decisively improves the control time of the room air control system (e.g. VAV supply air volume controller by SCHNEIDER Elektronik).

Advantages of the variable fume cupboard control depending on the sash opening height

The breakout protection from toxic substances of the fume cupboard in combination with minimum air consumption is guaranteed at each sash position. The sturdiness of the fume cupboard operation in terms of air ventilation is achieved by suitable parameter setting of the constant face velocity and can be adapted to any fume cupboard designs.

The device iCM500 checks the three sensors for plausibility and the correlation between the actual values of the differential pressure sensor, airflow sensor and sash position sensor. This constitutes a substantial improvement of the safety for the entire control system and for the user. Measuring errors and deviations are detected immediately and signaled by an alarm.
