Industrial recirculating chiller for laboratory applications
For consistent distillation results, maintain accurate temperature control with a compact recirculating chiller that ensures efficient cooling for a variety of liquid formulations.

Regulates and Circulates Cooling Liquids
The Recirculating Chiller F-325 from BÜCHI Labortechnik is an efficient cooling solution designed for laboratory and industrial applications. It integrates seamlessly with Rotavapor systems, enhancing distillation and temperature-sensitive processes by maintaining a stable cooling range from -10 to 25°C. This chiller supports diverse operations, from pharmaceutical tablet production to biofuel processing, accommodating end-products like insulin and biodiesel. Designed with an ECO-mode, it optimizes energy use by entering standby mode when inactive, thus reducing heat emission. With a cooling capacity of 2500 W, the F-325 efficiently circulates liquids while operating in continuous or manual modes, tailored for demanding environments. The unit’s compact dimensions of 1100 x 660 x 560 mm ensure easy integration into laboratory settings or alongside other industrial equipment such as vacuum pumps. The 9-liter tank capacity suffices for extensive operations, while the option for customization allows adaptation to specific process needs, ensuring compatibility with a range of industrial standards.
