The OptiClimate Water Cooler Compact Ultra Light is the closed-loop cooling solution designed specifically for RevomaxII and Pro series OptiClimate systems. Instead of consuming continuous mains water, this cooler recirculates the hot water leaving the unit, cools it down and returns it to the system ready for use. The result: near-zero water consumption, more stable performance and a system capable of operating outdoors even at temperatures above 40°C.
Its compact and ultra-lightweight design makes it ideal for space-constrained installations. The vertical model can be wall, ceiling or floor mounted, adapting to any room configuration. It is possible to connect one or multiple RevomaxII units to a single cooler, provided the cooler capacity exceeds the total thermal load of the system.
How it works
Hot water from the RevomaxII flows to the outdoor cooler via PE piping. The cooler's fans dissipate the heat to the outside, returning water at the optimum temperature to the indoor unit. The system requires a circulation pump (not included) and can incorporate automatic fan speed control via the OptiClimate Smart Box.
▸ Closed-loop circuit: minimal water consumption.
▸ Compatible with water or water/glycol mix (recommended in cold climates).
▸ Operable at outdoor temperatures above 40°C.
▸ One cooler can serve multiple OptiClimate units simultaneously.
▸ Optional pump and fan control via Smart Box.
▸ Vertical installation: wall, ceiling or floor mounting.
▸ Ultra-compact and lightweight — the most manageable unit in the OptiClimate range.
▸ Standard V 1/4" hydraulic connections for quick installation with PE piping.
▸ Engineered and designed in Holland.
