Paints, coatings and cleaning solvents give off a mix of vapours that are harmful to breathe and flammable in quantity. A VOC detector reports the total as one figure, switches the ventilation locally and keeps the record over cellular. Where one solvent dominates, a cell for that compound is the better choice.
Most solvent vapours are heavier than air and collect at floor level and in pits.
The sum of the vapours matters for ventilation, even when no single compound stands out.
Where vapour can reach a flammable mix, a combustible gas detector in %LEL belongs beside the VOC reading.
| Target gas | VOC |
|---|---|
| Selectable ranges | 0-10 / 50 / 100 / 500 / 1000 ppm |
| Mounting height | Depends on the gas or vapour expected |
| Where the detectors go | Low near storage racks and dispensing points; in spray booths and at their exhaust; along coating and printing lines |
| Outputs | Two alarm relays, 4-20 mA and RS485 Modbus RTU, all at once |
| Reporting | RS485 into a Genesis controller, then over cellular to alerts and a record |
The detector relays switch the fan, close the valve or sound the beacon locally, with no network involved.
The same reading goes over cellular to the people on the alert list, wherever they are, with acknowledgement recorded.
Concentration, time and duration are kept on a record that exports to Excel, for the incident review and the next inspection.
VOC when the vapour is a mixture and ventilation is the goal. A specific cell, such as xylene or styrene, when one solvent dominates and its own limit applies.
Which gases, how many points, where they sit and what they report into. We come back with the cells, the ranges and the positions.
