Electrical flange type immersion heaters The series of electrical Flange Type FHK-L provides a solution for the heating of liquids / molten salts or similar applications in process tanks or underground tanks. It can also be tank filling levels with very low heat, since only the lower horizontal portion is heated. The flange heater consists of a number of heating elements, which are built into the process flange. The electrical wiring is done in a robust electrical terminal box.

Immersion heater with cores The range of core immersion heaters type FHK-P offers a heating solution for liquid media where a low heat density is required. The special element / sheath arrangement allows the element cores to be withdrawn for inspection without system drain down. The standard heater consists of a number of core elements fitted into a process flange. A robust terminal box protects the electrical connections. The number of elements fitted depends upon the media to be heated and the kilowatt rating required. Dependent on application, the heater can be provided with temperature control by contactor or thyristor.

Electrical flange type immersion heaters The range of immersion heaters type FHK offers an economic heating solution for process tanks, pressure vessels and similar plant. The standard heater consists of a number of rod elements TIG welded into a process flange. A robust terminal box protects the electrical connections. The number of elements fitted depends upon the media to be heated and the kilowatt rating required. Dependent on application, the heater can be provided with temperature control by contactor or thyristor.

Electric duct heater Electrical duct heater type “LEH-R” are intended for the heating of gaseous media. The main applications are the heating of air in ventilation - / air conditioning or heat-recovery installations. Wide use areas are applications of the process - / environment-technology i.e. at the catalytic afterburning of exhaust fumes or drying ovens or in the plastic - / textile or paper industry. Through a variable construction concept, diverse use possibilities emerge. The application of highly compacted electrical heating elements with high purity compacted magnesium oxide powder sheathed metal tube and the direct heat transfer at the medium to be heated leads to an efficient realization of the electric energy to thermal energy. Special materials of acid constant rustproof steel stand for the heating of aggressive media by disposal. Alternatively, the heaters can be delivered also in the materials INCOLOY, INCONEL, HASTELLOY and MONEL. The duct heaters essentially consist of the following main-components: Duct with adapters to flanges DIN EN 1092 Rod heating elements Temperature Sensors (Thermostat / Thermocouple / RTD) Electrical terminal box

OKS 1105 prevents the formation of electrically conductive layers and minimises the risk of flashovers and dielectric losses. The insulators and switchgear covered with the paste thus maintain a good insulation resistance. Sealing lubrication for electrical or electronic equipment such as relays, plug-in connections, cable lugs and lamp sockets Protection of insulators and switchgear in humid atmospheres, for example of junction boxes, screw terminals, overload cutouts at high-voltage pylons, connecting cables and terminal connections Lubricant for plastic screw connections and other moving parts of metal, ceramic, plastic Advantages and benefits Excellent water repellent properties Excellent surface wetting Good adhesion on glass, porcelain and plastics Stable consistency across a wide temperature range Very good resistance to chemical and weather-based influences (e.g. ozone, UV radiation) Neutral with regard to many materials

Combustible Gas Detection - upgrade to upper class! Monitoring the environment for explosive gases most of the time you would be looking for hydrocarbons. It is a characteristic of hydrocarbons that they have a number of C - H bonds. These bonds absorb infrared light at a wavelength of 3,4 mm ( unsaturated hydrocarbons absorb at 3,3 mm ). This effect can be used to reliably detect these substances The most important advantage is that they are resistant against catalyst poisons and high concentrations. They can even be used in oxygen free atmosphere. Another important advantage of this technology is that a failure cannot go unnoticed. If an important component such as the lamp or the detector fails, the system will recognise this as 100 % absorption (an alarm situation). Most infrared gas detectors are designed as so - called NDIR (Non Dispersive Infra Red) double- beam detectors. This means, the light beam is divided in two portions with different wavelengthes. One is the measuring beam that will be absorbed by gas, the other is a reference beam at a wavelength that will not be absorbed by gas. This beam compensates for intensity variations of the lamp, dirt and corrosion. As the optics are mostly self maintained, an eventual inspection only checks if there is gas access to the sensor. Therefore much longer maintenance intervals compared to the catalytic sensor can be justified. As a rule of thumb, twice as long is OK. For plants which already have installed a combustible gas detection system, there is now a chance for a very cost- effective upgrade: The Statox 501 LC IR or LC MR! It consists of an EEx e (enhanced safety) terminal box and a sensor with integrated electronics. This sensor operates at the same supply voltage as a catalytic sensor. Its output signal is also identical to the signal of a catalytic sensor! This new innovative technical approach keeps the price in the same ballpark as catalytic sensors! All advantages of an infrared gas detector are now available for nearly the same price as a catalytic sensor and existing gas detection systems can now be upgraded without replacing the existing hardware. Of course the miniaturised chip inside the sensor cannot provide the same powerful electronics and software package as a high- end instrument, but however the new Compur Statox 501 IR LC features the most important advantages of an infrared system. So the next time maintenance is due with your gas detection system, check with Compur Monitors. The investment for an upgrade might pay back within one maintenance interval.
