How does water-cooling work?
Oreon has developed a water cooling technology that can be used in almost any greenhouse or indoor facility in collaboration with renowned installers.
The water-cooling system usually consists of 2 water circuits separated by a heat exchanger. The first circuit provides a constant flow of water between the heat exchanger and the fixtures. Cool water is pumped to the lamps, where the water extracts the excess heat from the lamps. The hot water flows back to the heat exchanger, where it is cooled by the second circuit (separated from the first).
The water from the second circuit can come from a basin, but can also be actively cooled by a dry-air cooler, an HVAC or a silo. There are various options and together with the installer it is determined which solution best suits the specific business operations of the grower.

Reusing the extracted heat from the fixtures lamps by the water cooling technique is an extremely sustainable solution: by reusing the heat, a grower can make optimal use of the energy consumption of the LED fixtures and at the same time saves on cooling costs, resulting in maximum energy savings.
