Introduction
An industrial Copeland scroll air-cooled condensing unit, featuring a robust black frame, copper piping, multiple fans, and a control panel. It is designed for low-temperature refrigeration applications.
Pioneering Technologies for Best-in-Class Products
Copeland has consistently led the HVACR industry with innovative technologies for over 80 years. From the introduction of Semi-Hermetic and Hermetic Compressors in the 1940s-1950s to the high-efficiency Discus semi-hermetic and Copeland Scroll Compressors of the 1980s-1990s, Copeland has been a pioneer. Today, the company continues this legacy with products like the Copeland Scroll Fusion Semi-Hermetic Scroll and Stream line-up of Semi-Hermetic Reciprocating Compressors, both featuring CoreSense technology for enhanced compressor protection and system diagnostics. This innovation has resulted in an extensive range of solutions for refrigeration, heating, and air conditioning markets.
KHZ* LVL Condensing Units for Low Temperature
The KHZ* LVL- 7.5 to 15 HP CDU platform is specifically developed for low-temperature refrigeration applications. These condensing units integrate the highly efficient ZFI* KQE vapor injection compressor, which provides 20% higher efficiency compared to single-stage compressors. The units are equipped with CoreSense technology to manage discharge line temperature via Vapor Injection, ensuring reliability during low-temperature operation.
These condensing units are offered with a full scope of supply and are manufactured at Copeland's Cold Chain & Distribution Center in Chakan, Pune. This product range offers the widest selection of Scroll Condensing Units from 7.5 to 15 HP (ZXL, KHZ* LVL) for low-temperature refrigeration applications. Local manufacturing and stocking enable customers to receive units with faster lead times and customized products tailored to their specific requirements. These units are known for their excellent quality within the refrigeration industry.
