Inappropriate air distribution, poor temperature and humidity control and negative pressurization in the pressroom were adversely impacting printing operations. The HVAC system upgrade eliminated these problems.

• Two 40,000 cfm hospital grade custom air handling units (AHUs)
• Recirculation of 60,000 cfm from dust collection system
• Project paid for itself in nine months with energy savings
• Converted six air handlers, with flow of over 650,000 cfm to variable volume
• Conversion of temperature, pressurization controls to DDC
