The low thermal mass and rapid heat-up characteristics of lightweight, 1.1mm thick silicone rubber mat surface heaters makes them ideal for enclosure anti-condensation and de-misting duties
The low thermal mass and rapid, controllable heat-up characteristics of the lightweight, 1.1mm thick silicone rubber mat surface heaters makes them ideal for anti-condensation and de-misting duties within instrumentation and comms enclosures.
Specialised production techniques enable fine resistance wires or etched foil circuits to be precisely positioned over areas of virtually any shape or size to provide accurate and intimate heating without the risk of local overtemperature.
The heater elements are laminated between two sheets of silicone rubber, up to a maximum of 920mm by 2 metres, that is reinforced with glass textile to give high mechanical strength combined with flexibility.
Holes and cutouts to accommodate existing components or obstructions can be provided without disturbing the even distribution of heat.
As an aid to positioning and assembly, the mats can be supplied with self-adhesive backing.
Otherwise, the surface heaters can be fixed into place by clamping, strapping or lacing, for which eyelets can be provided if necessary.
The maximum continuous temperature for a Hawco surface heater mat is in the region of 180? C, allowing a generous safety margin for short-term overtemperature excursions as high as 230? C.
Supply voltage can be 230 or 115Vac 50hz or 12Vdc and the mats can be supplied with an in-built temperature limiter or sensor for connection to a temperature controller.
Hawco is able to meet one-off or custom-designed orders and to provide volume supply of standard designs held against scheduled delivery with guaranteed minimum lead times.
