Make Up Air Heating

Make-up air systems play a pivotal role in maintaining optimal indoor conditions, ensuring that buildings are comfortable but also safe and efficient. As buildings utilize heating, ventilation, and air conditioning (HVAC) systems to maintain desired temperatures, these processes can sometimes lead to an imbalance in indoor air pressure. Make-up air systems are designed to compensate for this by introducing fresh outside air into the building. This fresh air influx helps regulate temperature by either cooling or heating the space as needed. Additionally, by balancing humidity levels, make-up air prevents condensation and mold growth, which can have adverse health effects and damage building structures. Perhaps most importantly, introducing fresh air helps dilute indoor pollutants, ensuring that occupants breathe cleaner air and thus enhancing the overall air quality inside the building. In essence, make-up air is a guardian of comfort, health, and structural integrity by effectively managing temperature, humidity, and air quality.

  • Our makeup air system delivers forced mechanical ventilation to the project site, allowing treated air to circulate throughout it.
  • Our system raises the surface temperature of curing construction materials to speed up and optimize the curing process while still protecting quality
  • Manage site humidity by providing treated air; we can control site humidity with pressurization to speed up cure periods and limit the risk of mould.


  • Variable controller technology adjusts to the ambient temperature to provide consistent heat to the project while reducing fuel use.
  • Designed for reliability: We design for continual uptime since heating equipment must be ready to function in any scenario, from freezing weather to other challenging conditions.
  • Stainless Burner Head: Our modulating burner head allows you complete control. However, let's face it: the ambient temperature changes frequently, and the system must be prepared to respond.
