OptiClimate "water-cooled climate system without outdoor unit"



The water-cooled OptiClimate cools the air using water as a cooling medium and warms it up using ceramic heating elements. The OptiClimate has a water inlet and outlet. The inlet is connected to the water supply. The cold water is used to cool the air, causing the water temperature to rise from 35°C to 50°C. This hot water is then channelled via the water outlet or recycled. This is ideal for cooling objects near water sources such as canal houses, houseboats, yachts, swimming pools or greenhouses. The water-cooled OptiClimate is also perfect for historic buildings where no external unit may be installed. If your house has a swimming pool, you can use a water-cooled OptiClimate to cool your house and heat up the pool.
