ODCS ‐ Over Draft Control System

The Over Draft Control System (ODCS) maintains a constant pressure in the exhaust common manifold or required pressure (negative or positive) at the individual connector. Designed with EC-Flow Technology™, the ODCS takes advantage of US Draft Co. bi- directional pressure transducer and proprietary PID technology to rapidly respond to varying manifold or individual system pressure on Category I, II, III & IV as well as building heating appliance systems. Utilizing the Opposed Blade Damper (OBD), a VIC series control and pressure transducer, the system interlocks with fossil fuel fired heating appliances to maintain the required outlet pressure of the manufacturer. The ODCS meets all requirements for the National & International Fuel Gas Codes and the Uniform & International Mechanical Codes.

Application
Gas vents serving Cat I, II, III & IV appliance Pressure rated chimneys & L Vents
Construction
16 gauge 316L stainless steel housing and blades 1/2” 316L stainless steel bearings

EC-Flow Technology™

EC-Flow is a proprietary algorithm developed by US Draft Co in an effort to improve upon the current PID technology used for controlling vent pressures. EC-Flow utilizes predictive algorithms to achieve set-point faster during transient operation, and maintain smooth operation during steady state operation. EC-Flow is designed to operate electronically commutated motors, VFD’s and damper actuators.
