Custom Designed Heat Recovery System - Duct Work

A company in the metal casting industry had a need to recover heat rejected from a high temperature cast spinning process.

We designed and engineered a system that included an air to air heat exchanger that transferred the energy from the exhaust flue gas stream to a fresh air make-up unit or diverting flow based on indoor room temperature.

The custom control system activates dampers to automatically modulate the exhaust air through each season to maintain set point from 100% outside air for ventilation during the summer to 100% recirculation if needed to satisfy winter loads.

Operating 24/7 provided a significant natural gas savings.
