Fan Coils are designed to deliver conditioned air to the room space through the use of heated and chilled water circulated through a single or dual coil system. As filtered air is blown across finned, hydronic coils, heat is efficiently transferred between the water and air.

With over sixty years of engineering excellence, the Zehnder Rittling team members are experts in heat transfer, sheet metal design and control systems. We use that knowledge to maximize the effectiveness of our fan coil designs, and as a direct result, our Fan Coils lead the industry with the most advanced features available.
