Heat recovery ventilation systems have been used to control humidity in printing plants and ensure good indoor air quality.

• Humidity Control. Humidity levels that are too high can create problems with paper stocks and the drying time of inks, which can reduce productivity. Heat recovery systems can remove additional moisture from the air and reduce the size and operating cost of the dehumidification equipment. Optional humidification can be added to take care of overly dry winter conditions.
• Indoor Air Quality. Heat recovery ventilators can be used to provide the proper levels of ventilation without paying a large penalty in energy costs. Some units also can help reduce summer cooling costs. Good indoor air quality is an important component of a healthy, productive work environment.
