Don't settle for the standard. At MJC, we build our patented products and solutions to specifically match your facility's needs. Giving you the most efficient and best performing HVAC solution.
Air Turnover Units are the ideal solution for heating and cooling large open spaces. This unit is designed to intake air from the floor level and discharge conditioned air at the top section of the unit, keeping even temperatures throughout your facility.
Our air turnover unit eliminates stratification, lowers maintenance and energy costs, and provides complete temperature control.
1. Elimination of RTUs
2. Less Structural Support on Roof
3. Units maintained at floor level
4. Limited Unit static = Lower Fan BHP
5. Even Temperatures in Space for valuable product.
