Why Heat and Energy Recovery?

By recovering heat, the demand for energy decreases. Saved energy reduces cost and the consumption of coal, natural gas, and other fossil fuels, which eventually leads to carbon dioxide reduction.

Return on Investment

An important part of the heat loss of a building is caused by ventilation. A constant air change is required to introduce fresh air to maintain a comfortable and healthy indoor climate. The heat loss can be reduced when the heat from the exhaust air is transferred to the supply air.

Whereas the savings in commercial and residential ventilation applications might be easier to grasp, industrial ventilation applications also offer many ways to profit from otherwise wasted heat.

Consequently, a heat exchanger is almost always a beneficial investment – regardless of whether the exchanger is a rotary or a plate heat exchanger. All our models save sufficient energy to provide short amortization periods and valuable savings.

Carbon Dioxide Reduction

The combustion of fossil fuel contributes to the increasing amount of CO2 in the atmosphere. Higher concentrations of CO2 in the atmosphere adds to the greenhouse effect and increases the average temperature on earth.

The higher average temperature on earth will eventually melt the polar ice caps, increase the ocean level and cause climate change, etc.

Heatex contribution to the reduction of CO2 by cross flow and rotary heat exchangers totals:

  • Approx. 7.000.000 tons CO2 / year

This is equivalent to the pollution from 2.500.000 Cars!
