Emerson Copeland Scroll Compressors: ZR Series
Product Line: ZR Series
Key Model Example: ZR34K3E-PFJ-522
Category: Compressor
Date: October 10, 2022
Overview
Copeland Scroll compressors, a product line from Emerson, are engineered for comfort and precision cooling applications. They are integral to air conditioning systems, water chillers, rooftops, and close control units. The series offers flexibility through multi-compressor assemblies (tandem and trio) for large-scale systems, aiming for optimal comfort, reduced operating costs, and enhanced seasonal efficiency (ESEER).
Key Features and Benefits
- Superior reliability and efficiency due to Copeland Scroll axial and radial compliance.
- Extensive model range supporting refrigerants like R22, R407C, and R134a.
- Low Total Equivalent Warming Impact.
- Reduced sound and vibration levels.
- Configurable tandem and trio assemblies for improved seasonal efficiency.
Maximum Allowable Pressure (PS)
- ZR18 to ZR81: Low Side PS 20 bar(g) / High Side PS 29.5 bar(g)
- ZR94 to ZR380: Low Side PS 20 bar(g) / High Side PS 32 bar(g)
