Products & Services
Selective catalytic reduction (SCR) systems inject ammonia into boiler flue gas and pass it through a catalyst bed where the nitrogen oxide gas (NOx) and ammonia react to form nitrogen and water vapor.
SCR power supplies use silicon controlled rectifier (SCR) topology to provide well-regulated voltage and current output.
Thyristor surge suppressors are semiconductor chips used to protect circuits and devices from over-voltage and over-current.
Wire mesh and cloth consists of metal wires woven or knitted into a grid or screen pattern with openings determined by the mesh size or linear density of wires (wire per inch).
Air hose is used in pneumatic systems and controls, or as supply lines for pneumatic devices and tools.
