This MDP 200 sensor was designed for variable air volume (VAV) damper control as well as HVAC applications, such as room pressure monitoring, fume hood controls, furnace press switches, heat recovery systems, burner control, fan control, and filter monitoring.
The Carel HEOS Sistema is a high-efficiency solution for refrigerated cases. It features remote cases fitted with variable-speed BLDC compressors cooled by a water loop. Each case can adapt its operating pressure to the load conditions in real time, allowing the compressor to operate in the most energy-advantageous conditions.
ComStar International is introducing two new refrigerants. RS-44B (R-453A) is a low-global warming potential (GWP), energy-saving HFC refrigerant that replaces R-22 in a/c and refrigeration applications without an oil or component change.
