About the product
Refrigeration heaters are a sealed type of tubular heater designed for condensate evaporation and defrosting. Vulcanisation is made on the connection between the heater and the power cable using rubber or silicone. Vulcanised heaters are primarily used in refrigeration for defrosting evaporator fins and also at drip trays for condensate evaporation.
The tubular heating elements manufactured by us comply with the requirements of the PN-EN 603351 standard. We provide a CE declaration of conformity at the customer's request.
Bayonet heaters
Single-powered refrigeration heaters that come in a straight condition (so-called ‘I’ type), i.e. they do not have bent sections, are also referred to as bayonet heaters. With these heaters, the power cable comes out of only one end of the heater - an airtight rubber or silicone head.

Manufacturing limitations
* The maximum heater power we can offer depends mainly on the surface load present on the heater sheath, which is expressed in W/cm². The allowed surface load depends on the medium in which the heater will operate (e.g. water, oil, glycol, air) and the material from which the sheath is made. Our engineers will be able to adjust the best and safest power for the lifetime of the heater on the basis of the information received from you.
** The maximum length of the heating element in the straight state (before any bending) depends on its diameter and sheath material - we will not in every case be able to offer the maximum heater length given in the above table due to technological limitations.
*** Non-standard diameters are made to order which usually means a longer time to wait for a quote and a longer lead time. In the case of certain types of sheath material, there may be additional limitations.
In the case of bent heaters, the minimum internal bending radius is determined individually and depends on the sheath material and the degree of softening of the sheath in the production process. We would also like to remind you that, as a small-series manufacturer, so we are able to manufacture even individual heaters.
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.
