Caltronic Controls (India) Pvt Limited Andheri East, Mumbai, Maharashtra

Rapper Piston (Slug / Plunger) made of M.S Bright Bar with a SS button, press-fitted to its bottom face. Product is shipped with coating of anti-rust oil. Usually weighs 20lbs/9kgs.

Rapper Insulator Rod (FRP Shaft) is a critical component that transfers rapper piston impact onto discharge electrodes to dislodge dust particles & isolates the rapper from high voltage frame. Each insulator is built from the finest grade Epoxy Resin Bonded Glass Fibre (ERBGF) yarn under strictly controlled manufacturing process.   Details : Electrical isolation : 120KV (max) Thermal insulation : Up to 200degC (~400degF) continuous Impact strength : 25feet-lbs (avg)  

Used during ESP maintenance. One end of the Portable Grounding Stick is clamped to Earth plate and other end is tapped on ESP high voltage frame to discharge residual charge. Sticks are offered in light weight insulating material (PP/FRP/Wood) with 3mtr copper braided wire & Aluminium hook.

We are a trusted name, actively engaged in manufacturing, exporting & supplying of Insulator & Hopper Heaters. Owing to their wide industrial usage, we make them available in various shapes & power wattage. Our heaters are noted for their high-grade, excellent operational fluency and low maintenance requirements. Interested buyers can acquire them at moderate prices, from us. More about Insulator & Hopper HeaterHeating element is sheathed in SS304 tube having MGO as insulating material. Nickel plated FINS can be provided for better heat dissipation. Powder coated terminal box with compression gland comes standard with heater unit. Thermostat is offered separately. Power rating : Up to 20W per inch Operating voltage : 230V / 415V

Another variety that we bring to our prestigious patrons is Hopper Heating Pad. Made from the finest grade raw material and advanced production techniques, our Hopper Heating Pads feature long service life and optimum quality. We are reckoned as prominent Manufacturer, Exporter & Supplier of Hopper Heating Pads in the global market. Apart from this, we keep all the requisite amenities to address safe and swift deliveries. More about Hopper Heating PadThis electrical heating pad consists of wire heating elements insulated with two braids of glass-fibre yarn and impregnated with Class-H varnish. The element is spread over closely woven glass cloth carrier at a uniform pitch and sandwiched between two layers of glass-fibre cloth. Eyelets are provided for riveting/fixing these pads onto the hopper. These pads are suitable for both ESP & Bag Filter application. Thermostat is offered separately. Safe temp  :  300degC (max)

High Voltage Support Insulator support and electrically isolate discharge electrodes from ESP casing and collecting plates. Our support insulators are designed for high compressive strength to support the loads imposed by the high voltage electrodes and associated high voltage frames.Details : Alumina Content : 45% (avg) Operating Temp : 400degC continuous Axial Strength : 5MT compressive load Wall Thickness : 30mm (avg)

External Grounding Switch (Disconnecting switch) are used in conjunction with T/R sets and are operated to bring ESP internal potential to zero during maintenance shut down. Our Grounding Switches are fabricated of 1/8" MS sheet & then electrostatically painted with Epoxy-Polyester powder coating using latest technique.

Caltronic has built & put in operation over 1,00,000 rapper units worldwide till date. Reliability of our rapper is well established by an on-going record of trouble free operation in various applications. Their consistent satisfactory performance and long service life is assured by the use of best quality raw materials and strictly controlled / monitored manufacturing process. Our rappers are built to withstand extreme weather conditions.   Electromagnetic Rapper Coil (MIGI / ESI / EMIGI) are wound from Class-F super enamelled, electrolytic grade copper wire. The external body is welded to achieve moisture sealed housing & then electrostatically painted with Epoxy-Polyester powder coating using latest technique. Each unit is thoroughly checked for insulation, coil resistance & piston lift test using well calibrated instruments & test jigs. Over time the word “Rapper” has become synonymous with “Caltronic” in India.

Boot Seal is a crucial component in the rapping system that prevents moisture, rain water & cold air from entering penthouse; it is recommended to inspect it periodically & immediately replace cracked units for effective ESP operation. High quality rubber granules are used to make our boot seal. As per temp requirement & ambient conditions we make offer choices of Hypalon, E.P.D.M, Silicone, & Viton. We can customize our product with OEM name & logo embossed on it. Stainless steel clamps are offered separately.
