Rail Switchpoint Heating Solutions
SwitchPoint Heating Has been working for a ultimate way to heat rail and switch points for more than 30 years, using feedback from our customers adapting their knowledge and desires for improvement at our products. Our goal has been combining functionality with easy handling, installation, bringing down power consumption and at the same time increasing function as well as safety.
Our solution for switch point heating uses a technique where all rails are heated with low power elements instead of heating two rails with high power to get a heat transfer by radiation from support rail to moving rail. To us this seems like throwing away expensive electric power.
By keeping rail at a temperature just above 0°C during season when snow and ice can hazard security in railway traffic installed power can be kept low, temperature regulation is combined with a snow sensor overriding temperature control at precipitation in combination with temperature below +3°C
Our system brings possibility to heat all rails with a minimum of connection points. It´s possible to double or triple power output at sensitive areas locally with multiple elements connecting to end of stock rail element with a quick junction
Flexible Rail Heating Elements
Self-limiting Elements (max 130W/m) Are easy to transport and handle delivered as a coil with only a few kilos weight. Elements length can be adjusted on site with simple tools. Easy to install with supplied details.
The self limiting function in the element prevents element from burn out.
Elements are delivered as customised ready-to-use units or cut-to-length units. Elements are installed at rail with stainless steel channels and spring steelclips with various size for different rail types.
Elements can be installed side by side to double powerat a part or all or switchpoint to ensure good function at location with harsh weather conditions. In extreme locations elements can be installed at the inside of support rail to extend power as a complement.
Minimising interference during installation and maintenance
All connections are made by “Quick connect plugs” IP68. This system minimises “time in track with” “plug-in” and “turn to lock” function.
8-Core connection cable brings possibility to monitor all elements separately, detailed alarm signal brings easy maintenance.
One failing element does not affect function of remaining system.
Smart Control Panels
Computer controlled triac based control panels, module built for easy extension with built-in touch screen computer (one master panel can control several slave panels)
Control panel can be remote accessed by intranet, internet or modem, parameters can be changed, logged values for current, temperatures, errors, power-on, presented as diagrams or downloaded for further processing in ex. Excel.
Elements are monitored separately for all errors and alarms can be sent via SMS or internet for instant alert of maintenance personnel at fault.
Standard enclosures in fibreglass reinforced plastic with integrated dig down ground stand, enclosures in steel or aluminium if needed.
Light Weight Power Cable Channels
Install cables with dig down channels made by recycled plastics. Easy access, Heavy duty self-lock channels withstanding drive over with vehicles.
Weight 7 Kg/m brings low cost for transportation and easy handling.
