compact – user-friendly – modern

The VALEGRO series is a new generation of recirculating coolers developed by JULABO as a reliable partner for precise and efficient temperature control. With their powerful cooling capacity and modern design, VALEGRO units fit perfectly into any work environment and delivering exactly the temperature control your application requires.

They not only conserve valuable resources but also protect the environment: thanks to the use of natural refrigerants and intelligent, energy-efficient technology, these units operate sustainably and are future-proof. Intuitive operation, smart features, and flexible adjustment options make VALEGRO an all-rounder that makes your daily work noticeably easier – from precise laboratory experiments to demanding continuous industrial applications.

Why is VALEGRO so impressive in everyday use thanks to its user-friendliness?

When developing the VALEGRO recirculating coolers, the focus was on maximum user satisfaction. The ergonomically inclined OLED display, the easily accessible interfaces below it, and the clearly visible, illuminated fill level indicator ensure particularly convenient operation and also enable space-saving installation under the laboratory bench. This allows workflows to be designed more efficiently and valuable workspace to be gained in the laboratory. The removable venting grid also makes it easier to clean the condenser, thus contributing to the long-term consistent performance and high operational reliability of the device.

How does the menu navigation support safe and efficient operation?

All functions are easy and intuitive to use. Full-text prompts in German and English help users respond quickly to potential issues and ensure safe handling at all times. Useful functions such as timer, auto-start, and data recording facilitate process monitoring, increase efficiency, and save valuable time in everyday work.

What interfaces does VALEGRO offer for system connection?

The RS232 and USB-C interfaces are integrated as standard, positioned directly below the front display and easily accessible at all times. An Ethernet interface is available as an option, allowing the device to be seamlessly integrated into any network – for full access to all functions directly from your PC.

How can the pump pressure be precisely controlled on VALEGRO?

All VALEGRO models are equipped with a powerful pump. The standard models offer a maximum pump pressure of 1.1 bar, which can be controlled in individual percentage steps via the menu. Models with up to 3.5 bar pump pressure also feature an integrated pressure sensor, enabling precise pressure control via the touchscreen.

How does the VALEGRO series save energy – and protect the environment and your budget at the same time?

Models with a cooling capacity of 800 watts or more use particularly energy-efficient components such as speed-controlled compressors and fans. This significantly reduces energy consumption by up to 75% and noticeably lowers operating costs in many applications – resulting in a faster return on investment. At the same time, lower energy consumption actively contributes to climate protection.

How do I choose the right VALEGRO model?

VALEGRO recirculating coolers can be divided into four categories, offering the ideal solution for all types of temperature control applications depending on customer needs.
