German Engineered Stulz Make Up Air Units (MAU) For Most Efficient Indoor Air Quality Management

Large enclosed spaces with high human traffic, such as airports, data centers, commercial buildings, factories etc. need good ventilation for healthy indoor air quality, comfortable temperatures and air pressurization.

Make-Up Air Units (MAUs), as seen in this product video, provide an optimum supply of treated fresh air to large spaces that replaces contaminated air or air lost through exhausts and leakages.

MAUs first filter out pollutants from incoming fresh air from outside, suitably heat or cool it and then releases the make-up air into the room to maintain IAQ, temperature and pressure.

Stulz’s intelligently controlled MAUs improve the energy efficiency of standard HVAC systems by up to 60% as it's monitored and controlled by integrated automation with hardly any human intervention required. MAUs are customized to site requirements to deliver the highest efficiency and reliability.
