At Carlton Thermal Systems we can help you to solve critical heating problems with RICA manufactured microtubular heating elements for applications that require compact dimensions. These elements are designed to guarantee high performance in terms of durability, power density, working temperature and electrical insulation.
Microtubular Heating Elements
 "Microtubular Heating Elements")
Microtubular heaters comprise resistive wire insulated with compressed magnesium oxide and a stainless steel protective sheath.
According to customers’ needs they can be manufactured straight or spiral, with or without thermocouples.
The elements are available in circular, square or rectangular section and several dimensions, lengths and powers. The power and thermocouple cables are protected by metal braid or fibreglass-silicone sheaths.
