As we start to see temperatures fall, we also start closing doors and windows in our buildings. Now is when people start to think about indoor air quality, how to solve it and not lose all the heat. Employees deserve to work in a healthy environment and employers can provide this without losing all their heat.
A typical solution is often to install wall fans to take out the contaminated air. This is simple and inexpensive, but not quite a full solution. This will remove the inside air, but unless you replace that air, you will increase negative air pressure in the building, pulling all the heat out, creating cold drafts and potentially creating dangerous situations like doors slamming shut, sucking pilot lights out, or even freezing pipes!
So how can we replace the outgoing air without having to heat that fresh air you from low outside temperatures? Heat recovering air exchangers work great for this situation.
Commercial Air exchangers work by bringing cold fresh air into the building throught a set of tubes and running the warm dirty air around the outside of the tubes on its way out of the building. This pre-heats the cool fresh air, warming it within 5-10 degrees F of the inside ceiling temperature.
This system is incredibly simple and efficient, recovering heat and delivering the fresh air to where the workers are working and breathing.
Typical applications for air exchangers are welding and fabrication shops, machining shops, automotive shops, diesel repair shops, small engine repair shops. The system is also the best solution for high humidty applications like truck wash bays. Often these buildings are metal and have spray foam insulation making them air tight. If you don’t get the moisture out, the walls will rust. If you don’t replace that air, the negative air pressure issues will be significant.
