The SES460-2400  booster oil heating system is a versatile oil heating tool designed to aid oil processing in cold weather transformer installation and maintenance.  The SES460-2400 can be set up to boost oil processor return or supply temperatures. It can also be used as a stand-alone 40 GPM heating circulation system for preheating transformers and storage tanks in cold conditions. The variable speed positive displacement pumping system tops out at 40 GPM.  Three individually controlled 32 kW low watt density heating banks provide 96 kW of heating capacity.  When supplied by an oil processor (or pump) a pump bypass circuit is provided to allow the system to be used as a push through heating system.  A  weather-protected NEMA 4X control panel is provided.
