Product Overview

About the Screw Two-Stage Low-Temperature Unit

The screw two-stage low-temperature unit uses a single-unit two-stage screw compressor with rational matching of the high- and low-pressure stages, satisfying cooling demands that combine large temperature differences, high pressure ratios and large capacities.

An efficient oil separator, oil cooler and economizer are fitted as standard, effectively increasing cooling capacity at low evaporating temperatures. The stainless steel shell-and-tube dry evaporator resists glycol corrosion while the microcomputer controller delivers one-touch start, precise control and IoT remote alarm notification.

As a manufacturer founded in 2011, Fuliang integrates R&D, design, production and sales of industrial refrigeration equipment. Every unit is built with certified, first-tier components and can be engineered to your exact operating conditions — send us your requirements through the inquiry form for a tailored proposal.
