Well-tested construction
The Geovent MultiBox is a third generation ventilation control unit, based on the latest micro processor technology.
Five options in one box
The Geovent MultiBox can be used for pressure measuring, control, regulation and surveillance (with built-in alarm) of systems for process ventilation in the pressure area 10-9990 Pa. Furthermore, the MultiBox can be used as a power supply for the quick-turning motor damper, HMO-24.
Easy to use
The MultiBox is particularly useful for dynamic pressure regulation of systems with regulation dampers and/or fan with integrated frequency inverter. The required pressure or flow (pressure difference) is coded as a fixed point, and subsequently, the built-in regulator will adjust the damper or the frequency inverter. The alarm is activated, if the regulation does not keep the pressure/flow within the fixed alarm parameters.
- Speed regulation of fan with frequency inverter through an analog 0-10VDC signal.
- Control of 24V motor damper - On/off control of 24V motor damper.
- 18W 24VDC power supply for motor damper, etc.
- Monitoring of pressure / flow with acoustic and visual alarm.
- Pressure measurement with 4-digit display, which visually shows the present pressure in Pascal.
- Built-in pressure transducer 10 - 9990 PA.
- Input for light sensitive switch - Can activate fan or damper, when the welding process starts.
- Input for inductive sensor - can activate fan or damper, when the welding machine, grinder or lathe, etc., is turned on.
- 230V connection
