The DLSZ series are air-cooled circulating chillers (recirculating chillers) with a plate heat exchanger, for cooling laboratory and industrial equipment such as rotary evaporators and reactors. Fourteen models are available, with tank capacities from 5L to 200L and no-load minimum temperatures from -20°C to -120°C depending on the model - see the comparison table below for the specifications of each model. Verified shared specifications: a circulating flow of 35L/min and R22 / R404A / R407C / R134A refrigerant.

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.
