Product Overview

About the Two-Stage Compression Condensing Unit Series

The two-stage compression condensing unit series uses an internationally renowned screw single-unit two-stage compressor. Its motor is cooled by a refrigerant-oil bath plus liquid injection, ensuring smooth operation and improved motor efficiency even at low load.

A high-efficiency plate heat exchanger serves as the intercooler, increasing subcooling and raising the unit's COP. The programmable controller features a clean human-machine interface, precise temperature control and a standard RS485 interface for remote control — a complete, ready-to-install heart for deep-freeze systems.

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.
