Holroyd Pre-Formed Silicone Heater Mats

Silicone Rubber Enclosure Heaters

Built for use within sensitive electrical equipment, enclosure heaters maintain a constant temperature to offset severe cold or damp environments. This offers protection against frost damage, condensation and the risk of corrosion.
  • 120V or 240V models in standard sizes 
  • Bespoke options available
  • Choice of 25, 50, 100 and 200 watt versions
  • Maintains an ambient temperature between 11°C and 55°C 



Enclosure heaters can suitable for a wide variety of electronic and electrical systems, including medical production in cold temperature laboratories and essential outdoor equipment, such as CCTV cameras.  

OPEN DATASHEET

Available as Standard and Bespoke Options

Range of standard sizes between 127mm and 254mm in length

  • Standard lead lengths measure 1000mm
  • Optional integral or remote 15°C air temperature sensing thermostats
  • Bespoke designs in small quantities available on request
  • Heaters available with UL / CSA component recognition
  • Supplied pre-attached to mounting plate for easy installation

Advantages of Silicone Rubber Enclosure Heaters
Cold Resistance
Manufactured using etched foil technology for precise, even heating, enclosure heaters work to regulate temperatures and warm the air inside electrical devices.
Easy Installation
Thanks to a combination between long cables and their small size, enclosure heaters are easy to install within electrical systems.
Hard Wearing
Silicone rubber heater mats are resistant to photodegeneration, weathering, fungus, bacteria, acetone, alcohol, formic acid, break fluid, acetic acid, greases, hydrochloric acid, sulphuric acid, waxes, and plasticisers.
Corrosion Protection
Protecting against the risk of corrosion by maintaining optimal internal conditions. Regular maintenance allows for the early discovery of rust and scaling.

Wide Range of Applications

Due to their design and easy implementation, enclosure heaters are present across a vast range of industries.
