Rite Engineering, a CNC shop in Franksville, WI, had some problems. Their existing ventilation system only brought in unconditioned make-up air. This resulted in a number of negative effects, such as an overheated shop floor on hot days which forced them to shut down, employee discomfort and overall poor IAQ.

See how Modine’s Atherion dedicated outdoor air system helped improve the conditions at Rite Engineering.
