About the product
KGW-type heaters are designed to heat water in boilers, and KGO heaters are designed to heat light and medium oil. For both types of heating sets, the heaters are fixed in a steel mounting plate, and the electrical connection cover is a metal box.
The individual tubular heating elements are adapted to 400V voltage and they are connected in a triangle. The heaters can operate at a tank pressure not higher than 0.4 MPa.

How to place an order for heaters and heating elements
We would like to point out that each heater project should be treated individually, so before you decide to place an order we recommend to consult with our sales engineers by sending a quotation request via e-mail. In order to provide you a price quote as quickly as possible, we will need a set of the following information:
- a photo or technical drawing of heating element
- heater type
- application of the heater (the device in which it will be used or the medium in which it will operate)
- expected operating temperature
- power [W] or resistance [Ω]
- voltage
- dimensions
- mounting method (head/threaded sleeve, flange, etc.)
- type of electrical connector or power cable
- for cables, please specify minimum length
- quatity
Please do not hesitate to contact us in advance if you have any doubts or questions.
