OptiClimate is what you fit when you have stopped trying to solve heat with extraction. These are purpose-built grow room air conditioning units that heat, cool, dehumidify and filter in one machine - which means a sealed room where you control temperature and humidity independently of the outside world, and where CO2 enrichment finally makes sense.
- Pro 3 water-cooled: The flagship unit - heat is rejected to water rather than air, so nothing hot or smelly leaves the building. See all full climate control.
- Pro 3 Split: The split-system version for installations where an outdoor condenser is practical.
- Revomax II: A more compact climate unit for smaller sealed rooms.
- Water coolers: Matched water coolers for the water-cooled Pro 3 range.
- Air distribution: Plenum boxes and air distribution tubes to spread conditioned air evenly across a canopy rather than blasting one corner.
- Sensors and control: Temperature probes, humidistat with light cell, remote controller cables and replacement Pro 3 remote controls.
- Consumables and mounting: Replacement carbon filters in packs of three, flange replacements and insulating anti-vibration feet.
Why choose OptiClimate?
Full environmental control. A sealed OptiClimate room decouples your climate from the weather, eliminates the odour and noise of high-volume extraction, and makes CO2 enrichment viable. For year-round consistency, nothing else in the range comes close.
OptiClimate FAQs
Water-cooled or split?
Water-cooled keeps everything inside and rejects heat to a water loop - discreet and quiet, but you need somewhere for the heat to go. Split needs an external condenser but is simpler to install where that is possible.
Do I still need extraction with an OptiClimate?
A sealed room does not need continuous extraction, but you will still want carbon filtration on any air that does leave, and the unit itself takes replaceable carbon filters.
Can I run CO2 with it?
Yes - that is largely the point. A sealed, climate-controlled room is the only environment where CO2 enrichment is not simply vented straight out.
