Windis Zero – Hydronic Heat Recovery

Windis Zero is a patented control system designed for hydronic heat recovery in air handling unit coils. Windis Zero ensures optimal liquid circulation, maximizing energy savings and enhancing heat recovery efficiency. Windis Zero can be installed either in new or existing air handling units, regardless of the unit's brand. The system works seamlessly in all applications with hydronic heat recovery, providing a versatile and flexible solution for improving energy efficiency.​


​


Windis Zero for multiple exhaust air coil heat recovery


Windis Zero is also suitable for managing heat recovery systems with multiple exhaust air coils. In multi-coil applications, the standard delivery includes 2-way control valves, which individually measure the fluid flow from each exhaust air coil.

Low Operating Costs

The efficiency of heat recovery remains consistently high even during extremely cold conditions. Performance does not deteriorate, keeping supplemental heating needs minimal.

Quick Installation and Commissioning

Factory-assembled and tested solution reduces installation time and effort on-site.

Versatile Solution

Windis Zero can be installed regardless of the air handling unit brand. An ideal solution especially for retrofit projects.
