Secondary Circuit Systems

Secondary circuit systems make use of thermal energy from existing steam, thermal oil, cooling water and cooling brine networks. The control facilitates the automatic extraction of the energy required for heating and cooling from the primary system (via heat exchanger or by the direct injection of the heat transfer fluid).
