PRESTO W56 Process system

The most powerful, single-stage, highly dynamic temperature control systems

The water-cooled PRESTO W56 is able to quickly and efficiently control the temperature in applications requiring a great deal of power. Even at low temperatures, this model has large power reserves for demanding external applications.

The magnetically coupled pump allows the user to optimally adjust pump capacity to suit the application, even over large distances and height differences, as well as for pressure-sensitive applications. Use of the latest thermodynamic technologies means that the cooling capacity is automatically adjusted to the current power requirements. In combination with additional optimizations, this makes the PRESTO W56 very economical and energy-efficient.

Water-glycol up to +150 °C

Connection of an expansion kit ( accessorie) allows pressurized temperature control with water-glycol up to a working temperature of +150 °C.
