	WIRE WOUND FLEXIBLE HEATING ELEMENTS
		Wire wound silicone rubber heaters are Holroyd Components Ltd core product. Available from one off to large batch quantity with almost no limit to design variations to satisfy customer specification. A high quality product at competitive prices coupled with fast delivery times all backed up by a full design and technical service to meet our customers’ stringent requirements. All Holroyd heater mats are manufactured to conform to the EEC Low Voltage and EMC Directives and are CE marked accordingly.
	Silicone rubber because of its high temperature tolerance and superb electrical insulating properties is well suited to the production of heater mats. Holroyd heater mats are produced by laminating the evenly spaced resistance wires between two sheets of silicone rubber, reinforced with a glass textile to give improved mechanical strength. These surface heaters are suitable for applications where precise heating is required. Fine resistance wires accurately and precisely positioned over areas of almost any shape or size. The close even spacing of the wires ensure a uniform heat distribution over the entire working area. The maximum continuous operating temperature for a silicone rubber heater mat is 200°C, allowing for a generous safety margin for short term over-temperature excursions as high as 230°C. Being thin and light weight, silicone rubber heater mats have a low thermal mass and therefore have rapid heat up characteristics and a fast response to temperature control. Heater mats can be manufactured in almost any size and shape to suit the application, including holes and cut outs without disturbing the even distribution of heat. Also available is a range of in-built temperature limiters or temperature sensors to suit customer’s instrumentation. Holroyd surface heaters can be supplied with an acrylic self-adhesive backing to allow for easy positioning and assembly. A separate silicone adhesive system is available if required. These heaters can also be manufactured with eyelets, straps, hooks or Velcro as further options for fixing. As for heaters which are not for static applications we can supply a more rugged silicone material to allow for repeated handling which will give a longer life.
