Switch Heater El-Point: Parallel resistance constant wattage (W/m) trace heater, fluoropolymer insulated and with thermally insulating cover profile and mounting clip for freeze prevention on switch points.
Benefits:
Applications:
SSV type heating element is our best selling heating element for railway applications. The design of this flat stainless steel tubular heating element is made specially for the tough railway environment. The outer shield withstand corrosion and the inner construction is extremely resistant to heavy vibrations and mechanical shocks. The soft flexible design of the heating element makes it possible to bend the element for best fit on location.
The heating element has the following key features:
• Extreme resistant to mechanical chocks and vibrations
Long lifetime – good return on investment
• Dual electrical insulation
Secure no electrical shorts to outer shield/rail
• Energy efficient shape
Flat surface to maximize heat transfer to the rail
• Corrosion free outer jacket
Stainless steel AISI 316, 321 or MONEL 400
• Completely sealed connection
No risk of malfunction due to moisture and termination corrosion problems.
• Flexible length and shape
Made to fit the switch best possible
• Small physical size
Will fit narrow places in switch point
Applications:
SV Same flat stainless tubular heating element design, but slightly wider. The SV design is made where there is a demand for extra power. Up to 1000 Watt per meter.
The heating wire is a solid wire wounded in a spiral. The spiral is completely encapsulated in highly compressed magnesium oxide. The heating element has been through a thermo cycle to reduce the fragility. The element can be bended on-site or can be delivered pre bended.
SV can be delivered with multi-zone power output. E.g. first half of the elements makes 650 W/m and the rest makes 970 W/m. This Has been delivered for switch points where higher power was wanted at the toe of the point.
The SV heating element has the following key features:
• Resistant to mechanical chocks and vibrations
Long lifetime – good return on investment
• Multi zone heating
Increase the efficiency and saves energy
• High Power
High heating capacity for very challenging winter weather conditions
• Corrosion free outer jacket
Stainless steel 316, 321 or MONEL 400
• Completely sealed connection
No risk of malfunction due to moisture and termination corrosion problems.
• Flexible length and shape
Made to fit the switch best possible
• Small physical size
Will fit narrow places in switch point
Applications:
Cold and Hot (heated) Rail Temperature sensors Special Bracket for actual Rail. Side-rail mounted or Bottom-rail mounted.
The “Hot rail” sensor is normally mounted on the shoulder of the rail.
The “Cold rail” sensor is often mounted under the rail. This is to make sure that sunshine and the like is not making any disturbances in the cold rail temperature reading.
Applications:
Flexsible Clamps
SAN Electro Heat SSV and SV elements are mounted on the base of the rail by means of special clamp straps made of corrosionresistant chrome-nickel steel.
SAN Electro Heat SSV and SV elements are mounted on the base of the rail by means of special clamp straps made of corrosionresistant chrome-nickel steel. The chosen surface pressure guarantees an optimum in heat transfer. Beyond that it allows an unavoidable linear extension of the heating elements without limitation. The strong fixing right in front of the connection head prevents the heating elements from creeping.
Complete program of clamps for the stock rail and for the switch blade is available for these rail profiles:
Applications:
The System BLUE POINT operates with a concept of Master and Slave control cubicles (MS and SL).
The Master Cubicle handles all control functions including weather information.
If the system contains SCADA supervision software all communication is done through a Master Cubical.
The Master Cubicle is talking to all connected Slaves wired or wireless. One Master can talk to up to 7 Slaves The Slave Cubicle contains the same switch gear components as the Master but without weather station and rail temperature sensors. The slave turns the heat on and off dictated by the Master Cubicle.
Applications:
Intelligent RTU Unit
The Intelligent RTU unit stands up to very harsh environments. The specially developed, proprietary alloy enclosure provides noise immunity, vide temperature range, impact/vibration resistance and DIN rail mounting without special tools. The RTU is programmed to control all communication and input/output for the switch point heating. Software, Input/Output, communication and SCADA interface can be customized to fit into existing installations or to meet special demands.
Applications:
The cubicle cabinet is an important protective part of the system. The cabinet is designed for the demanding requirement in the out door railway environment. The cabinet is installed on DIN sized base, made from the same material.
Applications:
The maintenance free snow detector is specially developed for Railway application and has been used in connection with switch point heating for many years. The capacitive double sensor in the detector is made for long time use without maintenance. The special wind catch secures detection of drifting snow.
Applications:
Wind detection in horizontal direction. Used to detect snow storm or drifting snow (strong wind). Strong wind will increase the chill effect of the rail. A “wind alert” will ask the controller to increase the temperature target.
Applications:
Heating elements designed for the big corrosion challenges the street embedded switches gives. Complete city systems including control and weather forecast service.
