PRESTO W58x Process system

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

The water-cooled PRESTO W58x is able to quickly and efficiently control the temperature in applications requiring a great deal of power. This model features has an impressive cooling capacity of 33 kW at 20°C, thus ensuring that it maintains large power reserves over its entire working temperature range, especially at temperatures around -30°C to -40°C, which are often necessary for automotive testing.

The PRESTO W58x process system is equipped with a gear pump. As a result, bath fluids with a high viscosity, such as water-glycol mixtures at low temperatures of up to -45 °C, can also be used .

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. Combined with further optimizations, the PRESTO W58x is both incredibly economical and energy-efficient.

Water-glycol up to +150 °C

The PRESTO W56 contains a technical innovation: Connection of an expansion kit ( accessorie) allows pressurized temperature control with water-glycol up to a working temperature of +150 °C.
