2 Heaters for rail vehicles Development and manufacture of heaters for rail vehicles has a tradition for dacades with Schaltbau. Schaltbau s radiators and tubular elements for air and water heaters are the backbone of the air conditioning system and supply of warm water in rail vehicles all over Europe. To meet different demands we developed a great variety of products - our standard product line. Do you need a special variant? Do not hesitate to contact us. We also manufacture to customer requirements. In this case, however, minimum order quantities apply. Features Fully qualified for railway service Long life owing to special design Corrosion-resistant heaters made of chrome nickel steel (INOX) High dielectric strength, resistor wire embedded in watertight sheath Suitable for nominal voltages of 3 kv DC max.; dielectric strength 8 kv cold min.! Applications Heaters in air conditioning systems of European rail vehicles - also used for cross-border traffic Tubular elements for air heaters Schaltbau tubular elements are designed for use in electric convection heaters and heaters in ventilation and air conditioning systems of rail vehicles. When connected in series the nominal voltage over all serial elements is 3 kv. Radiators Our radiators are used where in addition to the air conditioning system of a rail vehicle further convection heaters become necessary as, for instance, in vestibules, corridors, sanitary facilities, and driver s cabs of multiple unit trains. They are also applied in rolling stock for commuter service where there is no central heating and air conditioning system. Heaters for the supply of warm water in European rail vehicles, also used for cross-border traffic Tubular elements for water heaters In water heaters of air conditioning systems and for heating tanks of drinking and service water, tubular elements are used. They serve a double function: they heat the water and protect the tank against freezing. The operating voltage of a tubular heater system is 3 kv max.

The right size of a heater 1. Maximum sheath temperature Watt density is the amount of power in watts which a heater produces per square centimetre of heated surface area (W/cm²). In accordance with UIC 0 the supply voltage may vary between -30 % and +2 %. With line voltage 3 kv DC a range of -0 % up to + % is tolerated including voltage peaks of KV for msec. duration. The wattage rating of the heater (P = U² / R) is, therefore, increased by the operating voltage squared. This means that with an overvoltage of 2 % the wattage rating of the heater goes up 6.2 % (+ % overvoltage even results in a 82 % increase of the wattage rating!). Notice that the wattage rating of the heater directly impacts the watt density. Consequently, the size of the surface area of the heating elements must be large enough to cope with this worst case and prevent the elements from burning through. depends on the minimum length of its coiled resistor wire and the maximum permissible sheath temperature. 2. Minimum length of coiled resistor wire The resistance element of an electric heater is usually in the form of a wire which is wound on an insulator in such a way that the individual coils are separate and do not touch. The wire has a specific diameter to be capable of carrying the current required. This results in a maximum resistance per cm of coiled wire. And from this the minimum length of a heating element necessary for a specific heat output can be derived. So the minimum length of the coiled resistor wire and the maximum sheath temperature should be taken into consideration in selecting the right size of a heater element. Sheath temperature can also be reduced by using ribbed tubular heater elements such as ZH103 and ZH1039 ones. Heater power required for heating rooms or service water is dependent on the following parameters: the volume of the medium to be heated (air or water) the specific heat of the medium the difference in temperature the time available Sheath temperature of the heating element plays no part in this. It is, however, important for deciding on the size of the heating element. Fire protection requirements specify the maximum permissible sheath temperature which is influenced by the coiled resistor wire and the size of the heating element!
