Advantages Of Wire Wound

Using evenly spaced resistance wires laminated between sheets of silicone, Wire Wound Silicone Heating Elements are ideal for prototyping or problem solving applications. Manufactured to customer specifications these heaters can be made to suit almost any application. High flexibility can be obtained using tough, robust silicone materials that are finding ever-increasing applications in industries. Having manufactured Wire Wound Heaters since 1972, Holroyd have all the necessary experience required to design elements which are suitable for even the most arduous environments.

Advantages of Flexible Silicone Rubber Heaters

Silicone rubber is ideally suited for the production of flexible heater mats with it’s low thermal mass, superb electrical insulation properties and robust construction. It allows high power densities and offers fast response to temperature control. With silicone’s wide temperature tolerance of –60°C to 230°C as well as being thin and lightweight it has distinct advantages over other forms of heating. Where direct, precise and intimate heating is required silicone heaters are the ideal solution.

Applications

Wire Wound Silicone Flexible Heaters are generally suited to low volume applications or applications which require a flexible yet robust heating element. Holroyd’s heaters are used in countless applications but Wire Wound Flexible Heaters have been regularly used for the following purposes; industrial catering, anti condensation, environmental control, composite repair of aircraft, GRP pipe curing and snow melting to name just a few. If your not sure if a Wire Wound Flexible Heater would suit your requirements then please contact one of our technical support team who would be only too happy to advise you.

Etch Foil Heaters

Advantages Of Etch Foil Heaters

Computer designed, chemically etched foil tracks are laminated between thin sheets of silicone to give precise, even heating. Suitable for both low and high volume production, Etched Foil Heaters have rapid heat up properties with precise temperature control. Suited to applications where high power densities are required, Etched Foil Heaters offer a more precise form of heating than their Wire Wound counterparts owing to wider heated tracks. Having manufactured Etched Foil Heaters for decades, Holroyd are experts in designing specific track layouts and meeting the most precise of customer demands.

Service, Design & Delivery

Providing a full design, prototype and production service, Holroyd can manufacture virtually any shape or size heater. Our Etched Foil Heaters offer customers a prototype design and OEM manufacture solution with delivery schedules suited to requirement. With average lead times of 2-4 weeks for full production (dependent on quantity) and urgent delivery of 10 days on prototype foil designs, Holroyd ensure a top quality, high-speed service from start to finish.

Kapton Heaters

Advantages of Kapton Heaters

A thin, flexible and semitransparent material, Kapton Polymide is ideally suited for the production of heater elements. With its fast and efficient heat transfer, low thermal mass and excellent resistance to chemicals, weather and radiation it allows for high power densities and offers fast response to temperature control. Where low profile, intimate heating is required Kapton Heaters are the ideal solution.

Similarly to the Etched Foil Silicone Heaters, Kapton is constructed from computer designed, chemically etched foil tracks which are laminated between ultra-thin sheets of Polymide to give precise, even heating. Suitable for both low and high volume production, Kapton Insulated Etched Foil Heaters have rapid heat up properties and allow for precise thermal control. For applications where high power densities are required, Kapton Heaters offer a more intimate form of heating than their silicone counterparts owing to their low thermal mass and thin and lightweight construction. Having manufactured Kapton Heaters for decades, Holroyd are experts in designing specific track layouts and meeting the most precise of customer demands.

Applications

Etched Foil Kapton Heaters are suited to both high and low volume applications, applications which require a rapid heat-up times or where even surface heating is required.

Pre-formed/ Assemblies

Advantages
Holroyd silicone heaters are suitable for applications where precise and intimate heating is required. Being thin and lightweight, silicone heater mats have a low thermal mass and hence have rapid heat up characteristics and fast response to temperature control. Silicone’s wide operating temperature range of -60 to +230°C and superb electrical properties give it a distinct advantage over other forms of heating. In applications where a heater mat is required to fit small diameter pipe-work a more precise fit can be obtained by using the pre-formed option. Holroyd can form and vulcanise silicone heaters to fit full or partial circumference of any pipe diameter. These heaters can be supplied with separate straps for fixing or can be permanently installed using room temperature vulcanising silicone adhesive or self adhesive systems. Holroyd can provide a factory fitting service for assembly of silicone heaters to customer components using vulcanisation or self adhesive methods. We have many years experience of fitting to complicated pipe-work, plates, tanks and many other forms.
