PRESTO L56w new

The water-cooled PRESTO L56w can temperature control applications with high power requirements very quickly and efficiently. It has a very high cooling capacity of 55kW at 20 °C, offering large power reserves for demanding external applications across the entire working temperature range. This is particularly true at low temperatures, such as those required in the automotive sector or for reactor temperature control in the pharmaceutical industry. The PRESTO L56w process system uses natural, environmentally friendly refrigerant and was also developed with a focus on energy efficiency. In many application scenarios, this leads to significant operating cost savings and thus to a faster amortization of the acquisition costs. At the same time, the lower energy consumption makes a positive contribution to climate protection. Magnetically coupled centrifugal or gear pumps allow the user to optimally adjust the pump performance to the application, even over long distances and heights, as well as in pressure-sensitive applications. Operation is user-friendly and intuitive via the large 7" touch display or via integration into comprehensive control systems.

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.
