Pentagon thermostats enclosure heaters Electrical Limited was established in 1973 by engineers who already had many years experience in the manufacture of power resistors. That wealth of knowledge has been maintained and expanded to the present day to be recognised as one of the U.K.'s foremost panel heaters power resistors manufacturers of Power Resistors. This website describes our extensive range of resistors, but Pentagon are also well known in the panel building industry for their range of heaters for preventing condensation in switch and control gear cubicles. anti-condensation heaters power resistors Manufacturers and suppliers of power resistors, anti-condensation heaters and thermostats. Our open wire-wound, vitreous enamelled and heavy-duty protected resistors can be supplied to precise customer specifications. Typical uses dynamic braking braking resistors include dynamic braking, starting resistors, discharge resistors and loading resistors. Our anti-condensation heaters are designed for use in switch and control gear cubicles to keep condensation at bay. Pentagon supplies a range braking resistors dynamic braking of thermostats for use with anti- condensation heaters. The range offers exceptionally rapid response, close operating differential and extreme sensitivity. Wire-Wound Vitreous Enamelled Resistors (Prefix PE) Pentagon vitreous enamelled resistors power resistors anti-condensation heaters are available in a range from 20 watts to 500 watts. The nickel-chrome winding is completely protected by several coats of vitreous enamel, which have been fired to produce a high reliability resistor, capable of withstanding adverse enclosure heaters panel heaters conditions. Resistors are supplied with tinned terminal tags suitable for screws, solder or on some sizes for 'Faston' terminals. Terminals bands are spot welded in position on the heat resistant ceramic former, and the winding in turn spot welded vitreous resistors braking resistors to the terminal before the enamelling process. The terminal bands are therefore an integral part of the resistor, protected by the vitreous coating.Pentagon Anti-Condensation heaters have been designed for use in switch and control gear thermostats dynamic braking cubicles, where a low wattage heater is required to prevent condensation. They comprise of a Pentagon vitreous enamelled resistor mounted in a sheet steel case and having a removable perforated sheet steel cover. There is a cable entry grommet at each end panel heaters anti-condensation heaters and 4BA terminal screws are provided on the resistor. These successors to the 'Europa' range have been recently redeveloped to give an attractive modern design which incorporates proven bi-metal technology. Pentagon Open Wire-Wound resistors anti-condensation heaters panel heaters are close wound with oxidised resistance wire and each resistor is fitted with an adjustable tapping clip as standard. The nickel-silver end bands and tapping clips are suitable for soldered connections, screw terminals or on some size dynamic braking thermostats 'Faston' connectors. Extra tappings can be provided on request. Mainly used for dynamic braking or where a pulse rated resistor is required. Heavy Duty Power Resistor Enclosures Pentagon high quality heavy duty power resistor enclosures(IP20) are manufactured braking resistors enclosure heaters from zinc plated steel and have a powder coated finish. Dimensions and power ratings for assembled resistors appear in the technical data page. Typical uses include dynamic braking, motor starting and load power resistors vitreous resistors banks.
