Welcome to our Technical Area featuring technical specs and FAQs regarding our bespoke heating elements. If you can't find what you are looking for listed below or have any other questions, please don't hesitate to contact us on +44(0) 1799 523177
Each order will be priced independently based on the quantity, complexity of the products and current production volumes.
Low volume orders can be processed in as little as 1-2 days, larger volumes will be reviewed independently.
You are paying for any additional working hours and resources to prioritise the processing, additional costs incurred for expediting material or components and re-planning of the current production schedule.
We have reviewed our supply chain and purchased additional stock to ensure there is minimal impact on the lead times of deliveries.
We will continue to be supported by DHL courier whom will prepare the export documentation as a result of the supply of a commercial invoice with each shipment.
We will be shipping under EXW or DAP depending on the delivery location.
Cost is dependent on several variables, including size and specification. For prototype work, set up charges are minimal. The lead time on small quantities is normally 10-14 days including the design stage.
Wire Wound elements are manufactured using a resistance wire that is looped around pins. It is ideally suited for small quantities, larger sizes and low-cost sampling. Not only can it be used in adhesive static applications, but also where repeated flexing is required.
Etch Foil uses a chemically etched track much like a printed circuit board suited to high power densities and medium to large quantities – they are used mainly in static applications and where even heat distribution is critical.
Comprising of a wire or etched resistor laminated between sheets of silicone rubber compound, these heaters are ideally suited for the heating of surfaces in a multitude of applications.
As standard, silicone heaters are manufactured to IP64, however we can manufacture to IP65. We are currently working on achieving ratings as high as IP67.
Heaters can be supplied with thermal limiting devices hard wired directly to the heater. Temperature sensors such as thermocouples, PT100’s and thermistors can be fitted to the heater mat for connection to external process controllers. Holroyd Components can also offer a range of controllers.
We have ISO 9001:2015 approval which is audited by the British Standards Institution (BSI)
All our products meet all the relevant European directives and are CE marked accordingly. VDE approval as well as UL/CSA recognised products are available upon request.
We can provide detailed power calculations and offer advice for individual applications. Heat up times will depend on many variables such as ambient temp, mass & specific heat value of the product and whether thermal insulation is utilised, for example. For more detailed specification, take a look at the technical data sheets or get in touch to discuss our range.
Practically any shape, size or profile is available along with holes, cut-outs and slots within our maximum range. We can advise no matter what your requirements.
The temperature of a mat can range dependant on the material used and many other variables. Silicone can be suitable from -60°C to +250°C and Kapton -40°C to +200°C.
For static applications, a self-adhesive backing is a simple, quick method of installation. Where removal is requested, hooks, eyelets and springs, Velcro and magnetic bindings are available. We can offer many configurations suited to your specifications.
The heaters are a pure resistor and therefore can be designed to suit any supply voltage, AC or DC, single or three phase.
