AL-KO HYDRO-OPT® – System for optimal heat and cold recovery
Save energy and reduce operating costs. AL-KO HYDRO-OPT is available in the HYDRO-OPT S and HYDRO-OPT M versions. Hydraulic stations of the AL-KO HYDRO-OPT series are energetically necessary when supply and exhaust air are spatially separated in ventilation systems. They recover heat from the exhaust air and transfer it to the supply air via heat exchangers. AL-KO HYDRO-OPT M is designed for connection to 1 supply air and up to 3 exhaust air units.

Description
Why heat recovery? In central ventilation systems, heat recovery is one of the most important adjusting screws for improving energy efficiency. Closed-circuit systems (CCS) consist of one or more finned heat exchangers in the supply and extract air, connected via a hydraulic circuit. AL-KO optimizes the interaction of all KVS components. The AL-KO portfolio contains finely tuned systems with high-performance heat exchangers for the various corrosion protection classes. The highest efficiency requirements can be realized with hydraulic stations of the AL-KO HYDRO-OPT series. They are available in different performance and comfort levels.
