Applications
Anywhere people gather or crops grow, carbon dioxide builds up and has to be managed. It is the same plug-and-play unit throughout — an industrial NDIR sensor reading 400–5,000 ppm and a relay that switches your existing fan or CO2 source — tuned to each space by the thresholds you set on the front panel.
Meeting rooms cross 2,500 ppm within 90 minutes. VentPlus keeps staff alert and productive.
Read moreThe most densely occupied room in any building. A full class passes 1,500 ppm within the hour.
Read moreExercising members produce six to eight times the CO2 of someone at a desk.
Read moreCrowded halls routinely cross 3,000 ppm; VentPlus drives fresh air in automatically.
Read moreContinuous measurement, automatic ventilation, and a logged record you can show an auditor.
Read moreA closed bedroom climbs past 2,000 ppm overnight — VentPlus helps you wake up fresh.
Read moreNo windows means the fan is the entire air supply. VentPlus decides when it runs.
Read moreFull houses build CO2 fast. The same unit and thresholds as a banquet hall.
Read moreHold the 400–2,500 ppm enrichment band, with one socket for the CO2 source and one for the fan.
Read moreHigh CO2 for spawn run, low for fruiting. Holding the fruiting band is where cap quality is won.
Read moreSealed rooms deplete below ambient within an hour of lights-on. Enrich, then vent at night.
Read morePrecise CO2 control for stacked, sealed indoor growing. Same controller as a grow room.
Read moreSealed rooms accumulate CO2 from produce, dry ice and R744 refrigerant. Alarm and ventilate before anyone enters.
Read moreBrooding trades ventilation for heat. Run minimum ventilation on the CO2 number instead of a timer.
Read moreFermentation is a continuous CO2 source in an enclosed space. Covered by the cold-storage configuration.
Read moreReliable CO2 control for enclosed barracks and underground command posts. Contact us for requirements.

Every application above uses the same VentPlus Main Unit (model HO-202) except greenhouses, which use the two-socket GH-202 configuration so a CO2 source and a ventilation fan can be driven independently. What differs between a classroom and a mushroom room is not the hardware — it is the Fan ON level, the Fan OFF level and the alarm level, all of which you set with four keys on the front panel and can change at any time.
If your space is not listed, tell us the room volume, how many people or how much crop is in it, and what fan or ventilation you already have. We will tell you what to set — or tell you honestly if VentPlus is the wrong device for it.
Room dimensions, occupancy or crop, and whatever ventilation you already have. We will recommend the model, the number of units and the thresholds to start from.
