1 / 25The Swiben GDX-20/30 is a two-in-one temperature circulator that combines a low-temperature cooling circulating pump with a high-temperature oil bath in a single unit. It operates across a temperature range of -30°C to 199°C and serves applications in research, chemical, biochemical, and medical laboratories.
The unit uses a sealed liquid circulation system with an expansion vessel that is mechanically connected but isolated from the main circulation loop. Because the loop is closed, the system avoids drawing in water vapor at low temperatures and oil mist at high temperatures, allowing heat transfer oil to operate across a wide working range.
With a 20L capacity, a circulating pump delivering 25 L/min flow and 6 m lift, and combined heating and cooling in one container, the GDX-20/30 is suited to labs needing both deep cooling and sustained heating from one device.
A single integrated heat-exchange container provides both heating and cooling to the circulating fluid, which moves through a sealed loop driven by a 100 W pump. An expansion vessel sits outside the active circulation path so the working medium stays below 60°C regardless of loop temperature. CFC- and HCFC-free refrigerants handle cooling, while a 3000 W heater supports high-temperature operation.
