If you are afraid that the airconditioning heating will be making a lot of noise, we can assure you that the OptiClimate is the most quiet system available. We like to emphasize that our airconditioning heating consumes as little power as possible and we have a dual room function option as an option, with which you cool two rooms with only one OptiClimate. The fan of the PRO3 can be placed in two different positions (not the Inverter). Of course, the heating function is important with the use of an airconditioning heating, but also the humidity in the space is of importance, because it involves your health. Moisture is everywhere in the air and it can have a negative effect. It can cause unpleasant odors but also mold, rot or rust, elements one does not want in the house or in a company, as it can lead to allergens and dust mites. OptiClimate’s airconditioning heating takes care of the humidity and it cleans the air by filtering using a built-in dust and carbon filter. Even under the most extreme circumstances our climate control systems delivers an ideal living and working environment throughout the year.
