Electric flat tubular point heaters for railways
Our electric flat tubular point heaters type RKW have been used for all types of rail profile and points by German and other railway companies for many years.
When the cold season sets in with snow, ice, ice rain, and high temperature fluctuations, railway points can fail due to the accumulation of ice and snow between the point blade and the stock rail.
To avoid this kind of disruption, a flat tubular point heater is placed between the point blade and the stock rail, in special cases also at the blade, to keep the space between the blade and the stock rail free of ice and snow by heat conduction and heat radiation.
We supply flat 13 x 5.5 mm tubular heaters of different lengths ex stock for all point radii. They are made of high-quality corrosion-resistant chromium-nickel steel.
We also supply tram point heaters of salt-resistant chromium-nickel steel, material index 1.4876 (Incoloy 800) in different lengths, capacities and voltages.
Heating rods for stock rails and point blades of standard points
Our ex stock range comprises all single-connection flat tubular heaters type RKW, complete with connecting sleeve specified in the table below. These heating rods comply with protection class IP 65 and are used for normal rail points with profiles S49, S54, and UIC 60. The design with encapsulated cable is compatible with the design with connecting sleeve.
Heating rods for high-speed rail points
Rail points of type ERL, profile UIC 60 (Butzbach type) are used on high-speed railway lines. This type requires only one connecting end for each sleeper unit and so the bent shape illustrated below is obtained. The new shape of the heating rods ensures intensive heating of the lubricant-free sliders.
Lock heaters serve to keep locks and linkage free of snow andice. The lock heater consists of two heatconducting plates, to each of which a heater is clamped and which are placed in the sleeper unit below the locks to be heated. The position of the connections can be changed by turning one or both plates by 180°. If heaters of 2x 250W are used, intensive heating of the lock is ensured, if heaters of 2x 450W are installed, the whole lock unit is heated uniformly. The two plates (with plate thickness of 3mm) are electrically and mechanically connected with each other and are placed in the lock unit. We supply the heating elements in (standard) encapsulated or disconnectable design.
The cable length of the encapsulated version is eight meters. These lock heaters are supplied as complete units with corrosion protected heat-conducting plates, heaters and fastening elements.
Heating rods and accessories for resilient moving frogs
The wing rails and block unit of movable frogs are heated. The heating rods are located at the rail neck, in type ERL points, the rail foot is also heated.
Heating rods for tram point heaters
For the heating of tram point heaters are also used flat tubular heating elements. Due to the higher operating voltage an increased high voltage resistance is provided. The cross section can therefore be selected flat oval 6 mm x 12 mm. Because of the increased corrosion risk through de-icing salt we use with a higher resistant stainless steel.
