Variotherm temperature control used in combination with suitable mould inserts allows variations in temperature of more than 100 °C in critical areas or in complete moulds. In order to achieve this, the SINGLE ATT system operates with two separate circuits that contain thermal fluid with a different temperature. Both ATT circuits contain the same fluid. Water is recommended for temperatures of up to 200 °C, while oil is suitable for applications that operate with temperatures of up to 300 °C.
