Door Heating

RTR Technologies' Door Heating Systems facilitate the operation of the doors in inclement weather and under severe weather conditions. RTR has an installed base of over 50,000 units installed. This translates to unparalleled access to actual field-tested data. As a result, RTR has developed considerable expertise regarding the optimal thermal profile, energy demand, consumption and energy efficiency tailored to each application.

Electrically Heated Door Thresholds

Transit Vehicle thresholds are made of metal. The doors slide in a door guide and it is critical that the guide is kept clear of ice and snow to prevent slipping hazards. RTR's Self-Regulating and Constant Wattage Threshold Heaters keep thresholds free of ice and snow without the need of costly electro-mechanical controls. While reliably maintaining ice and snow melting performance, RTR’s Heating Technology keeps surface temperatures of the threshold well within a safe temperature zone for passengers and rail personnel.

Other Door Heating Applications

Door Pocket Heaters
Door Track Heaters(Guide)
Door Surround Heaters

Auxiliary Heat

Auxiliary Heat includes all other freeze protection on the cars and allows for the proper functioning of systems in sub-zero temperatures. Auxiliary Heating is tailored to specific applications. Many of the Freeze Protection applications are specific to cars that have dining, bedrooms, and toilets and are applied in Potable Water Tanks and delivery systems to allow for water to dispense to sinks, dining locations and bathrooms. Auxiliary Heat is often applied to:

Fill / Drain Line
Pneumatic / Hydraulic Systems
Valve Heating
Couplers

Pantograph and Pan Head Deicing Systems

RTR is the originator and single source of these specialized Deicing Systems with a 100% share of the market. These systems prevent the accumulation of snow and ice on the Pan Head so that there is consistent contact with the contact wire, rather than bouncy, intermittent contact, which can cause voltage surges, spikes, arching, possible damage to the wire itself, or in worst case, collapse of the pantograph.
