The more powerful VALEGRO recirculating coolers are designed for larger and more complex applications. They feature a precisely adjustable, increased pump pressure up to 3.5 bar.
Whether in the laboratory, research, or production, the VALEGRO 2503 recirculating coolers offer a constant cooling capacity of 2.5 kW at 20 °C, supporting stable processes around the clock. These modern units offer precise temperature control for a wide range of applications and, thanks to their compact design, fit seamlessly into any working environment. The refrigeration circuit uses an eco-friendly, natural refrigerant. When designing 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 and simple to clean level indicator make daily work easier. The inclined OLED touch display is easy to read and ergonomic to use. The intuitive menu navigation allows quick access to all functions. Warning notices and system messages are displayed in clear, understandable language, ensuring maximum safety when using the unit. 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 use from the front.
