VALEGRO 1801H

Temperature control tasks in laboratories, research, and production require a high degree of precision, efficiency, and flexibility. The compact air-cooled VALEGRO 1801H recirculating chiller combines these requirements in a single unit: With an operating temperature range of -20 to +85 °C, a cooling capacity of 1.8 kW at 20 °C, and a temperature stability of ±0.2 °C, it ensures stable conditions and reproducible results — even during demanding applications in continuous operation. The modern chillers offer an optimal ratio between cooling capacity and unit size combined with a high level of user-friendliness. Whether in the laboratory, in research, or in industrial production, VALEGRO recirculating coolers are reliable partners whenever precise temperature control is required. Thanks to their compact design and quiet operation, they fit seamlessly into any working environment.

Energy Efficiency with Measurable Results

Speed-controlled compressors and fans adjust their output as needed, reducing energy consumption by up to 75% in many application scenarios compared to uncontrolled systems. This significantly lowers operating costs and helps the initial investment pay for itself more quickly. At the same time, JULABO relies on natural refrigerants, thereby consciously choosing an environmentally friendly and future-proof technology. Another advantage of speed control is its exceptionally quiet operation: By adjusting the output to meet demand, the sound pressure level of the VALEGRO 1801H is significantly reduced.

Extended Temperature Range for Versatile Applications

Thanks to its integrated heating function with 2 kW of heating power, the VALEGRO 1801H covers a temperature range from -20 to +85 °C. This makes it equally suitable for cooling and heating tasks—without the need for a separate device. The continuously adjustable pressure pump delivers a discharge pressure of up to 1.1 bar at a flow rate of up to 23 L/min and can be adjusted as a percentage via the menu.

Focus on User-Friendliness

The ergonomically angled OLED display, the illuminated and easy-to-clean fill level indicator, and the tool-free removable ventilation grille make daily work easier. The intuitive menu navigation with full-text prompts in German and English, comprehensive help texts, and features such as a timer with start and end time scheduling, autostart, and data logging improve process monitoring and boost efficiency. The filling volume of 4 to 7 L offers flexibility for a variety of applications.

Connectivity and Integration

USB-C and RS232 are integrated as standard and accessible directly below the front display. An optional Ethernet interface enables integration into networks and full remote access via a PC. All VALEGRO models are air-freight-compatible (total refrigerant charge under 100 g) and can therefore be delivered quickly worldwide.
