Immersion heaters

Solution for heating of fluids such as water and oil

DESCRIPTION

Immersion heaters represent reliable and cost effective solution for direct heating of liquids such as water, oil, etc. Complete heating surface must be immersed in heating fluid.
Tubular heating elements are U-shaped and soldered, brazed or welded on threaded or flat flanges or nipples. Wide spectrum of flanges as well as materials for flanges and heaters enables us to meet almost every costumer's requirement. We produce heaters with protective caps, thermostats and thermal fuses and thermostat protective tube. As an alternative, there are also immersion heaters made of ceramic elements for indirect heating.
We have a wide range of elements on stock so we could deliver products in short period of time. We also offer customized immersion heaters as desired.
