Cyrkulator grzewczo-chłodzący (Chiller-Heater) GDX-20/30, 20 L

Description

The GDX-20/30 heating and cooling circulator is a laboratory temperature control device designed for applications requiring stable heating or cooling of external systems. The unit combines refrigeration, heating and liquid circulation in one compact device, making it suitable for laboratory and technical applications.

Recommended for: 20 L and smaller jacketed glass reactors, laboratory condensers and external closed-loop systems requiring stable heating or cooling circulation.

The device operates in a wide temperature range from -10°C to 199°C and is equipped with a circulating pump providing a flow rate of 25 L/min. The 20 L tank capacity makes it suitable for laboratory setups requiring controlled temperature circulation and stable thermal conditions.
