PTC Air Heaters
Extremely versatile, our PTC heaters can be used in various applications across multiple industries; to meet these diverse needs, we offer two types of designs: honeycomb and fin. Our fin PTC air heaters have several advantages. They’re designed for optimal safety, and, because they self-regulate, there’s no risk of overheating — which means they also offer superior conductivity, efficiency, and longevity. Our fin PTC air heaters are offered in various designs; low air resistance and high-heating efficiency models are available, and single or double insulation can be used. Pelonis honeycomb PTC heating discs, meanwhile, are made from an advanced ceramic material with over 1,200 holes to enable safe, energy-efficient heat transfer in small spaces. Honeycomb holder assemblies are available in three-, four-, or five-disc configurations, and custom orders are also available.

Ultra-Thin Flexible Heaters
Thanks to their unique physical and electrical properties, our ultra-thin flexible heaters offer superior performance and more effective heat transfer than other options on the market. With thin construction and a low-mass design, these ultra-thin heaters are well-suited for applications with limited space. Featuring built-in nanotechnology that provides greater flexibility, these heaters also transfer heat more efficiently and evenly than foil-imprinted heaters — resulting in faster heat-up and warm-up times.

Pelonis Ultra-Thin Flex Heaters

Immersion Heaters
Offering high thermal conductivity, our ultra-high-temperature ceramic immersion heaters allow for better efficiency than other metallic and nonmetallic heating elements. Self-regulating and eco-friendly, Pelonis immersion heaters are built for optimal user safety. They also have excellent insulation properties, and can be used in both water and air.
