Maxi-Flo heat exchangers are specially designed for heating pool water or water in hot tubs. They are most commonly used with gas or other boilers, or solar collectors. We recommend installing a suitable automatic control from Vagner for reliable and convenient operation. Maxi-Flo and Hi-Flow heat exchangers transfer heat from the source to the medium where it is utilized. They are made of high-quality AISI 316 stainless steel, 100% tested for tightness, and have a special construction with flow limitation to ensure efficient heat transfer. They are designed to minimize pressure in the heating system and are compact in size, requiring minimal installation space. They come with stainless steel brackets and can be supplemented with special screws for connecting the secondary circuit ("thermal bridge"). Maxi-Flo: Max. pressure: primary circuit 10 bar, secondary circuit 10 bar.
