Coil Heaters / coiled heating elements WRP
Mickenhager spiral tube cartridges in various dimensions and cross-sections offer a high electrical heat output in a small installation space and are mainly used for heating spray nozzles and hot runner manifolds as well as welding rulers and sealing rollers.
A particular advantage lies in their variety of geometric shapes (diverse geometries), as they can be manufactured in almost any geometric shape in addition to the stretched and coiled versions.
