Direct Fired Make-Up Air & Indirect Fired Make-Up Air

A wide range of industrial and commercial facilities require the use of make-up air units often due to environmental needs or building envelope needs. These units often are filtration and heat only systems that move larger quantities of air. There are many solutions and options available when looking at make-up air units including energy recovery systems, dehumidification, integrated cooling, and customized solutions to meet the exact need of the project. These units are designed to improve indoor air quality and building health.
