Heat tracing systems for piping, tanks and vessels contribute greatly toward problem-free operating cycles in the chemical and petrochemical industries, in refrigeration plants and in mechanical engineering. The conventional applications are protection against frost and maintaining or raising the temperature of piping, vessels and valves for media such as water, oils, fats and greases, waxes and a variety of chemicals. With many media, trace heating reduces their viscosity and makes them easier to pump. Other media crystallize or condense if the piping or vessels are not maintained at the appropriate temperature or are not heated up to that temperature.
Our task begins with engineering: we allocate a number of heating circuits to the process systems, calculate the heating capacity, and select the devices and components necessary for the installation.
We use tracing cables with FEP insulation, or mineral insulation with a stainless steel outer sheath, both having a constant resistance per unit length. In addition, self-limiting tracing cables with various ratings are also available. Their heat output decreases with rising temperature.
The required temperature control can be achieved with explosionproof capillary tube thermostats (controller and high temperature switch), but also with resistance temperature detectors. Both the conventional electromechanical and the electronic versions of the high temperature switches undergo the functional test required for the explosionproof heaters.
If required, the installation on site can be carried out by our staff. Our expertise in explosion protection and the associated thermal tests guarantee a fully functional system conforming to the standards and regulations.
