Rectifiers Dealers in Kolkata

TRUs impress DC Currents in to the Carbon-steel/steel structure to be protected in opposite direction to the galvanic corrosion currents & protects the structure from corrosion. To obtain the optimum level of protection under varying conditions, it is necessary to vary the impressed current continuously so as to maintain a constant level of protective potential at the structure. This continuous monitoring and control can be achieved by providing an automatic control for the cathodic protection system.

Components of Electrostatic Plant for coated abrasives manufactured in our works, These relays are mainly used in control of machine tools, chemical plants, cranes, and other industrial applications. Also industrial electronic controls, such as, thyristor converters, industrial inverters, high voltage variable frequency power supplies, etc. are some items worth mention.

Starting with the supply of diodes for traction application, Hirect now caters to wide range of rectifiers for rolling stock application. High power electric locomotive, AC Electrical Multiple Units are powered by Hirect̢۪s on-board or under slung rectifiers. Hirect rectifiers are also installed on board Diesel locomotives and Diesel-Electric Multiple Units. Rectifiers for special purpose like OHE cars, Mobile Maintenance Units, Accidents Relief vans etc. are also catered. On-board Installation and Under-carriage slung version of rectifier sets are manufactured by highly trained work force and specially created infrastructure for a high degree of reliability in critical traction application.

WELDMAN series of Thyristorised Welding Rectifiers are fully electronically regulated transformer rectifier unit having constant current characteristic, suitable for manual metal arc welding and as a power source for TIG welding and Gouging.The machines have been designed to ensure good quality of welding even by a beginner. The use of technically best suited raw materials along with innovative design makes them very reliable and suited for continuous heavy duty operation. The unit is housed in a sturdy sheet metal casing, suitably ventilated, having four wheel, two of which are swiveling and are complete with a handle for easy movement. The machine is provided with lifting hooks for transportation by crane.Other optional accessories like remote control and power factor correction capacitor can also be provide at extra cost.
