VALEGRO Recirculating Coolers

Modern, user-friendly chillers for a wide range of cooling tasks

The new VALEGRO recirculating coolers are environmentally friendly all-rounders for a wide range of cooling and heating tasks. They are characterized by a good ratio between cooling capacity and unit size as well as an optimal usability.

The modern devices offer precise temperature control for a wide range of applications in laboratories, industry, and research. Their compact design allows them to fit seamlessly into any working environment. They use an eco-friendly, natural refrigerant and can be ideally adapted to the requirements of the customer's application thanks to an adjustable pump. During the design of the VALEGRO recirculating coolers, the focus was on maximum user-friendliness. Many helpful features such as a timer function, a removable venting grid that can be removed without tools, and an illuminated, easy-to-clean level indicator make everyday work easier. The inclined OLED touch display is easy to read and ergonomic to use. With the intuitive menu navigation, all functions can be accessed simple and quickly. Clear warnings and understandable messages secure safe handling of the units at all times. In addition to RS232 and USB-C interfaces, VALEGRO recirculating coolers are also available with Ethernet (optional). All interfaces are located directly below the display and are easy to access from the front.
