OptiClimate Pro 3 Grow Room Air Conditioner – Water-Cooled

Cool, Heat, Dehumidify and Filter From One Unit

The OptiClimate Pro 3 Series water-cooled air conditioner cools, heats, dehumidifies, filters and circulates air in one system. Because it works with water rather than coolant gases there is no outdoor unit, so the space stays fully enclosed and installation needs no refrigeration engineer. Ceramic heaters deal with low temperatures, the water circuit with high ones. Each model's water use and electrical supply are in the table below.

What’s Included

• 1 x OptiClimate Pro 3 Internal Unit
• 1 x Controller Unit
• 1 x Temperature Probe
• 1 x Humidistat / Light Sensor
• Top-of-room mounting: 1 x flange, 4 x insulating anti-vibration feet
• Remote or low-level mounting: 1 x plenum box, 2 x flanges (intake and outlet)

Key Benefits

• Five functions in one unit – cooling, heating, dehumidification, filtration, circulation
• No outdoor unit required, so the grow space stays fully enclosed
• Much lower energy consumption than a traditional air conditioner
• Pre-heat and slow cool-down eases plants into day and night cycles
• Auto-shutdown on leakage, with alarm system connection
• Generates useable water for your reservoir

Temperature Swings and Overnight Humidity Spikes

A room that bakes under the lights and drops sharply at lights-off never gives stable VPD, and you get excessive stretch, poor nutrient uptake and airy flowers. Overnight humidity is the other half, sitting high in the canopy where airflow is weakest. Holding both in a set band keeps transpiration on track.

How to Use

• Mount at the top of the grow area with the flange and feet, or away from it with the plenum box and two flanges
• Connect the cooling water in and out, from mains water or a closed-loop water cooler
• Site the probe and humidistat/light sensor at canopy height
• Set separate day and night targets to follow the lighting cycle
• Route the warm water outlet to a drain, or recirculate it through an OptiClimate water cooler
