Job Description:
A VariTrac III and Tracker 10 will be installed at B&R Specialty Metals. The VariTrac CCP is
applied to the office area HVAC system. This HVAC system consists of Voyager CV unit
supplying 3 separately controlled zones. VariTrac is applied as a changeover bypass system and
uses a bypass damper assembly to monitor and control supply air static pressure and
temperature. VariTrac devices required for this job include the following:
VariTrac CCP
VariTrac UCMs (3)
Zone sensors (3)
Communicating Bypass Damper assembly
Tracker is used to control the warehouse area and brazing workshop. Tracker controls scheduling
