PRESTO W56—Single-Stage Dynamic Temperature Control System

Julabo’s water-cooled PRESTO W56 can be used rapidly and efficiently for temperature control applications with high performance needs. The system has huge power reserves for difficult external applications, even at low temperatures.

The temperature control system includes a magnetically coupled pump that enables the user to adjust the pump to the ideal capacity to suit the application, even over height differences and huge distances, and for pressure-sensitive applications.

The use of modern thermodynamic technologies implies that the cooling capacity is adjusted automatically to the existing power needs. When the PRESTO W56 is used along with additional optimizations, it turns out to be energy-efficient and highly economical.

Water-Glycol up to +150 °C

The PRESTO W56 features a technical innovation: The connection of an expansion kit enables pressurized temperature control with water-glycol up to +150 °C working temperature.

Benefits

100% Checked

The PRESTO W56 ensures 100% testing and 100% quality. Every JULABO Circulator is subjected to quality testing before it can leave the factory.

Green Technology

Eco-friendly materials and technologies are constantly developed.

Touch Display—Perfect Operation

The user always has an overview of all values and functions with the help of a touch display. The multilingual and intuitive menu structure allows ideal control.

Convenience for Several Users

Administrator level for personalizing instrument settings, password protection, user levels with restricted permissions for quick and secure defined access, and all levels can be adjusted.

100% Cooling Capacity

“Active Cooling Control” is available for cooling over the entire range of working temperatures. Quick cool-down can be achieved even at higher temperatures.

Intelligent Temperature Control

Intelligent cascade control enables self-optimizing and automatic adjustment of the PID control parameters with an external stability of +/− 0.05 °C.

Control from the External Application

External Pt100 sensor connection is provided for accurate measurement and direct control in the external application.

Highest Measuring Accuracy

“Absolute Temperature Calibration” is available for manual compensation of temperature difference and 3-point calibration.

Intelligent Pump System

The temperature control system features constant and reliable pump capacity, automatic adjustment of pump capacity based on viscosity, and electronically adjustable pressure value or pump stages.

Multiple Interfaces

Data management, remote control, and incorporation into process structures can be performed easily. Ethernet, USB, SD card, RS232, and alarm off are built-in permanently. Additional interfaces are available as accessories.

Space-Saving Footprint

All the connections as well as the supply and exhaust air are situated at the front or rear, without any venting grids on the sides. Units can be positioned next to each other or the application.
