VALEGRO 250

The VALEGRO 250 from JULABO is an air-cooled recirculating chiller designed for a wide range of temperature control applications in laboratories, research, and production. With an operating temperature range of -15 to +40 °C and a temperature stability of ±0.5 °C, the unit delivers stable thermal conditions — even during continuous operation. The cooling capacity is 0.25 kW at 20 °C. Of particular note is the use of a natural, environmentally friendly refrigerant, which reduces the ecological footprint of laboratory operations.

Intuitive Operation — Even Under the Lab Table

The ergonomically angled OLED touchscreen is easy to read and allows for convenient operation — even when positioned under the lab bench. The intuitive menu navigation with full-text prompts in German and English ensures quick access to all functions. Warnings and system messages are displayed in clear, easy-to-understand language. With overall dimensions of 24 × 46 × 44 cm and built-in casters, the unit fits flexibly into any work environment.

Flexible Pump Capacity and Easy System Integration

The high-performance pressure pump can be adjusted continuously in individual percentage increments via the menu. With a flow rate of 11 to 22 L/min and a delivery pressure of 0.1 to 0.4 bar, the VALEGRO 250 covers a wide range of application requirements. RS232 and USB-C interfaces are integrated as standard and accessible from the front, directly below the display.

Connectivity and Advanced Process Functions

RS232 and USB-C interfaces are integrated as standard and accessible from the front, directly below the display. The following functions are available for efficient process monitoring:
