The GDSZ series are high and low temperature circulators (heating and cooling circulation devices) for temperature control of reactors, rotary evaporators and other laboratory equipment. Twenty configurations are available, combining tank capacities from 5L to 100L with temperature control ranges starting at -20°C, -40°C, -80°C or -120°C and reaching +200°C - see the comparison table below for the specifications of each configuration. Verified shared specifications: a circulating pump flow of 42 L/min and a lift of 28 m.

Voltage note for US customers: This unit operates on 220V. Standard US outlets supply 110–120V, so a 220V circuit or a suitable step-up transformer is required.
