INTRODUCTION
The 06Z screw compressor family is a variable frequency
drive, twin screw, oil injected helical rotor compressor. This
manual is for the Carlyle
®
variable speed screw compressor
product line, which is comprised of three frame model sizes
06ZC, ZF, and ZJ. Carlyle offers distinct versions of the vari-
able screw compressor for Medium/High Temperature applica-
tions qualified with R-134a, R-1234ze, or R-513A refrigerants.
The following compressor features are offered:
• Variable Vi valve to optimize compressor efficiency.
• Integrated discharge muffler.
• Wide variable speed range to maximize compressor capaci-
ty.
• Standard 2-pole induction motors.
The operational limits, required accessories, and operational
guidelines are contained in this manual must be complied with to
stay within the compressor warranty guidelines.
R-134a, R-1234ze, or R-513A Applications
The 06Z series compressors are designed for air-cooled R-134a,
R-1234ze, or R-513A applications only.
Each variable screw compressor is designed to be applied with
a dedicated, performance-matched oil separator. This
compressor / oil separator assembly can be applied in a
medium-temperature or high-temperature refrigeration circuit.
Carlyle offers the required oil separators as shown on page 20
of this application guide.
Scope
This application guide is intended to familiarize system design-
ers with the variable screw compressor and to provide technical
information necessary to assure safe and reliable compressor op-
eration.
Certifications
UL and CSA approvals have been obtained for specific 06Z
screw compressor models applied with R-134a, R-1234ze, or
R-513A.
UL File #: SA4936
CSA File #: SA4936
UL, CSA, and CE approvals have been obtained for all voltage
combinations shown on page 18 of this guide. These compressor
models also comply with the EC Low Voltage and Machinery
Directives.
Compressor Offerings
The three variable speed frame sizes (06ZC, 06ZF, and 06ZJ) are
optimized for application in economized refrigeration circuits.
Table 1 notes the available variable speed screw compressor
model offering.
