Product Overview

About the Piston Single-Unit Two-Stage Low-Temperature Unit

This unit uses a brand-new imported piston two-stage compressor capable of cooling the secondary refrigerant down to -55 °C — deep-freeze territory that single-stage systems simply cannot reach.

The water-cooled condenser is built with high-efficiency external-groove copper tubes for excellent heat conduction, and the stainless steel shell-and-tube dry evaporator combines strong heat exchange with effective protection against glycol corrosion. The microcomputer controller provides one-touch automatic start, precise temperature control and IoT remote monitoring with alarm push.

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.
