Description

DRA SM

The SM model is a 7kW split system with reverse cycle function to accommodate both cooling and heating. The HVAC system is made up of two assemblies namely the condensing unit (condenser and compressor) and the evaporator unit. The condensing and evaporator unit is a Daikin system, which is ruggedised and rebuild by SME to withstand the railway conditions. The condensing unit is usually mounted below the coach or loco. This product is service proven and a large quantity has been installed on saloon, kitchen and staff coaches.

DRA MR

The MR model is a 4.5kW split system with reverse cycle function to accommodate both cooling and heating. The HVAC system is made up of two assemblies namely the condensing unit (condenser and compressor) and the evaporator. The condensing and evaporator unit is a Daikin system, which is ruggedised and rebuild by SME to withstand the railway conditions. The condensing is installed inside the train door to accommodate the limited space available .

DRA RG

The RG model is a 9kW split air-con system with electrical heating. The unit is comprised out of three sub assemblies: evaporator unit, compressor and condenser unit. The Evaporator is typically mounted in the front floor area of the cabin. The compressor will be mounted direct in line with the supplied 220 VAC motor through a coupling and 24V clutch. This will allow for temperature controlled switching of the compressor without switching the driving motor off and thus extending the life of the motor.
