Small scrolls for lower GWP refrigerants

ZS-KA-ScrollGERMANY: Emerson Climate Technologies has released three ZS*KA Copeland scroll compressors for use with lower GWP alternative refrigerants R448A, R449A and R407A/F.

The new scroll range includes three models from 1.3 to 1.8 hp: ZS09KAE, ZS11KAE and ZS13KAE. They are said to be designed to suit a range of applications such as units for walk-ins or commercial kitchen equipment, integrated display cases, as well as cooling systems used in light industrial applications where smaller cooling capacities are required.

In addition to R134a or R404A, these compressors are approved and qualified for the lower GWP alternatives such as R407A, R407F, R448A and R449A. Emerson says it will release models for more refrigerants soon.

With evaporating temperatures from -25°C to 10°C, the ZS*KA compressors are said to have a wide operating envelope that allows end-users to operate the compressors at very low condensing temperatures for maximum energy efficiency.

“Within the past few years the demand for higher energy efficiency has become more prevalent in the commercial refrigeration market,” said Sylvain Lamy, Emerson’s director refrigeration marketing.

“With the implementation phases of the ERP regulation in 2016 and 2018, the efficiency requirement will become even more stringent and increase the need for highly efficient refrigeration compressors.

“The new ZS*KA models deliver up to 15% higher efficiency at rating conditions and 28% higher efficiency at low condensing limits against the commonly used competitive piston hermetic compressors. This gives unit manufacturers the possibility to qualify their units without making major design changes,” he added.

The new models are manufactured in Europe in Emerson’s factory in Northern Ireland and are available in different motor configurations. Additionally they can be fitted with an optional sound shell for quieter operation.
