Compact recirculating cooler range

Whether in the laboratory, in research, or in production — the new VALEGRO 250 recirculating coolers from Julabo provide a constant cooling capacity of 0.25kW at 20°C, thereby ensuring stable processes around the clock. These state-of-the-art units provide precise temperature control for a wide range of applications and, thanks to their compact design, integrate seamlessly into any work environment. The refrigeration circuit uses an environmentally-friendly, natural refrigerant. During the design of the VALEGRO recirculating coolers, the focus was on maximum user-friendliness.

The angled OLED touchscreen is easy to read and ergonomically designed for operation. The intuitive menu navigation allows for quick access to all functions. Warnings and system messages are displayed in clear, easy-to-understand language, ensuring maximum safety when operating the unit. The VALEGRO recirculating coolers feature RS232 and USB-C interfaces located directly below the display - easily accessible from the front.
