The viscosity of oil such as hydraulic or lubricating oil changes with the temperature. It is thicker when it is cold, which, in the long run, can lead to fast wear and tear of machines and systems, e.g. in the case of lubricating oil supply systems. This is when electric oil preheaters are deployed. They quickly and precisely keep the oil at or heat it to a certain minimum temperature and thus at a viscosity level preventing machine damages. Depending on the individual characteristics of the oil, the preheater delivers a clearly defined heat.

The quality of the system decisively depends on specifying the matching surface load for the respective oil and its flow velocity, since an excessive film temperature will cause the oil to crack at the heater. Stalls should be part of the design and construction.

Our solution for oil tanks consists of a cartridge heater the pipe of which is screwed in or flanged to the container. The heat source is provided by a ceramic heating element which can be replaced without draining the oil.

However, solutions ensuring long-term stability have also been developed with usual screw-in type heaters or flanged heaters, also as continuous flow heater based on tubular heating elements.

We have been successfully engaged in electric heat technology for more than 25 years and have internationally developed and manufactured reference solutions for the chemical, mechanical and plant engineering industry. We specify and manufacture our products according to international standards (DGRL 97/23/EC, AD2000, EN 13455, ASME) and, if required, with approval by TÜV/GL/DNV etc
