Our products include valves, controllers, space sensors, monitors, fume hood controls and network integration products. Our valve controller products include Celeris®, Theris® and Traccel®. Celeris® valve mounted controller valve body has its own controller that is configured on the job site to perform specific valve level and room level control, as well as report information it knows about itself and the functions it is performing to the BMS. Designed for high-performance lab applications, each valve controller monitors a flow feedback potentiometer and provides actuation control for repositioning the valve for air flow control. Our pressure Monitor II (APM2) measures and indicates true pressure differential between two rooms or spaces in a building for the purpose of ensuring integrity of ventilation & airflow, presenting room status & measured values on a large LCD touch-screen display.
