Implementing the Hartman TRAV technology product in new or retrofit applications is very straightforward. Each Supply and return air fan must be operated with variable frequency drives, and configured for a variable flow distribution network in which the loads are served by VAV terminal units. An effective network capable DDC system must connect all VAV boxes and the central fan(s) together as a single system. With this configuration, you are ready to implement TRAV control and watch the energy bills go down and comfort compliments rise!
