Energy Recovery Systems
Secondary and tertiary heat recovery systems can help reduce operating costs. Heat recovery through the use of air-to-air heat exchangers or air-to-thermal fluid systems can be added to equipment to capture heat and return it to the process. Steam or hot/chilled water can be supplied through the addition of waste-heat boilers or absorption chillers. In areas where building heat is required, water/glycol systems can be installed to capture heat from the process and use it to preheat building makeup air.

Heat Transfer Fluid Filtration System
Inline filtration system cleans and maintains the efficiency of heat transfer fluids, thermal or hot oils. Filter housing uses proprietary filter elements that can withstand up to 750oF (399oC) system temperatures to enhance oil cleaning at elevated temperatures. Sentinel Series is a stand-alone system that will recirculate a portion of the fluid through the filter unit and discharge the clean fluid downstream into the main piping at a pressure higher than the system. Vector Series offers the same filtering capability except that it uses the existing system pump to recirculate the fluid from the pump discharge through the filter and then to the pump suction.
