50kVA Unit

Category: Electrical equipment

We have a wide range of heat treatment units that are designed specifically for preheat and post weld heat treatment applications using electrical resistance heating. The units distribute power from a main electrical supply to electrical resistance heating elements at the correct rated voltage of 30V & 60V. The units have the facility to connect up to six independent heating circuits. An automatic temperature programmer may be incorporated within the unit which permits temperature control of each circuit in terms of heating rate, holding temperature & time and cooling rate. Additionally, the equipment may incorporate a multi-channel temperature recording instrument.

The low voltage units are particularly suitable for preheating welding and localising heat treatments on pipework. The units are available with air natural cooled transformers rated at 50 kW or 65 kW to suit the application. Each of the circuits is connected to a 60V secondary output and is therefore useful for a broad range of ceramic pads.
