Opticlimate Revomax II - All-in-One Grow Room Air Conditioning Unit
Best for: Serious and commercial growers who need precise, steady-state temperature and humidity control in a room that's currently at the mercy of the weather outside.
Our thoughts
This isn't an impulse buy - it's proper commercial-grade climate control kit, and the price reflects that. What you're paying for is genuine steady-state precision (temperature held within about 0.2°C of your setpoint) rather than the on/off swings you get from a standard AC unit. If your grow room's climate is genuinely holding you back, this is the kind of investment that pays for itself in consistency.
The Opticlimate Revomax II is an all-in-one climate control unit that handles heating, cooling, dehumidifying, air circulation and filtration from a single box - no separate outdoor condenser unit required, which Opticlimate markets as a world-first for this type of steady-state system. It uses Infinity DC inverter technology to modulate its cooling output down to as little as 20-30% of full capacity, compared with roughly 60% on most standard AC units, which means it can hold a stable climate even when your room's heat load fluctuates rather than cycling on and off.
This listing is the entry point into the Revomax II range, rated at 6000W cooling capacity - Opticlimate also sells larger 10000W, 15000W, 21000W and 30000W versions of the same unit for bigger rooms. It can be set up with either traditional water-cooled inlets connected to your water supply, or air-cooled via a separate split unit, and comes with built-in carbon and dust filtration plus a full suite of safety features including temperature protection, a water leak safeguard, fireproof housing and an SMS alarm system.
How it compares
The Revomax II sits at the top end of the grow room climate control market, aimed at growers who've outgrown standard portable or split AC units.
- Standard portable or mini-split AC units typically only modulate down to around 60% capacity, so they cycle on and off more and give less stable climate control than the Revomax II's 20-30% minimum.
- AC Infinity's climate control range is aimed more at smaller tent-scale setups with app-based monitoring, rather than the commercial-scale, all-in-one steady-state cooling the Revomax II is built for.
- Because it combines heating, cooling, dehumidifying and filtering in one unit, it replaces several separate pieces of kit (AC, dehumidifier, heater) that you'd otherwise need to buy and run independently.
It costs a lot more than a standard AC unit up front, but you're buying commercial-grade precision and an all-in-one footprint rather than stacking separate units together.
Usage guidance
The Revomax II is a purchase-to-order, professionally installed unit rather than a plug-and-play tent accessory.
Installation
Choose either a water-cooled setup (connected to your water supply, using 2-4 litres per minute when running) or an air-cooled setup with a separate split unit, depending on what's practical for your site.
Remote control
Pair it with the Revomax Smart Remote Controller to monitor and adjust the unit from anywhere via a secure internet connection.
Sizing
Match the unit's rated capacity to your room's total heat load (lighting, equipment and ambient heat gain) - if in doubt, speak to us before ordering, since this is a purchase-to-order item delivered on a pallet.

Who this is for
- Commercial or large-scale home growers who need genuinely stable climate control, not just cooling
- Growers running heavy LED or HID lighting loads that a standard AC unit can't keep on top of
- Anyone who wants heating, cooling, dehumidifying and filtering handled by one unit instead of several
- Growers who value remote monitoring and want to check on their room's climate from anywhere
Not a fit for small tent grows - this is built for dedicated grow rooms where climate stability directly affects yield and consistency.
Our take
This is a big investment, and it should be treated as one - it's aimed squarely at growers for whom climate instability is genuinely costing them yield or consistency, not casual hobbyists. The steady-state precision and all-in-one functionality are real, verified features, not marketing fluff.
Proper kit at a price that makes sense once you weigh it against buying separate AC, dehumidification and heating equipment and still not getting this level of control.
