Semi-hermetic Recip. Compressors (60Hz, IP-Units) KP-105-4

Product catalog summary
General Overview
Semi-hermetic reciprocating compressors are engineered for use with chlorine-free HFC refrigerants and HCFCs like R22. These compressors are durable and efficient, requiring Polyol-Ester oils approved by BITZER for operation with new refrigerants. Technical information is available for lubricants and retrofitting existing systems.
Technical Highlights
The Octagon® Series features compact models with displacements ranging from 173 to 2397 CFH. These compressors are versatile, suitable for R134a, R404A, R507A, R407C, and R22, and can be used for high, medium, and low-temperature applications. The VARICOOL system allows for user-selectable cooling methods. Key features include high cooling capacity, minimal energy requirements, wear-resistant drive gear, and a solid valve plate design.
Operation Modes with R22
The VARICOOL system optimizes cooling for different applications, using suction gas cooling for high and medium temperatures and direct suction with external air cooling for low temperatures. Advanced methods are available for larger, single-stage low-temperature compressors.
Application Limits and Performance Data
Application limits are specified for HFC refrigerants like R134a, R404A/R507A, and R407C, as well as HCFC R22. Performance data is provided for each refrigerant, detailing their efficiency and operational parameters.
Technical Data and Drawings
Technical specifications and dimensional drawings are included to assist in the installation and maintenance of the compressors. These details ensure compatibility and optimal performance in various applications.
Specifications
The document outlines the components of the refrigeration system, including compressors, control modules, temperature sensors, spray nozzles, pulse injection valves, and additional fans. It specifies the use of R22 for low-temperature applications and mentions the need for specific oils like BSE55 for certain refrigerants.
Performance Data
Performance data is based on ARI 540 standards and 60 Hz operation. It highlights the impact of saturated suction and condensing temperatures on cooling capacity and efficiency. The document notes that data does not include liquid subcooling, which affects the rated cooling capacity and efficiency.
Application Limits
The document specifies application limits related to return gas temperature, saturated suction temperature, suction superheat, and saturated condensing temperature. It provides guidelines for additional cooling requirements and limitations on return gas temperature.
Optional Accessories
Depending on the series, optional accessories include crankcase heaters, differential oil pressure switches, integrated start unloaders, capacity control, additional fans, water-cooled cylinder heads, and motor protection devices with additional functions.
Model Designation
The document explains the model designation system, including codes for the number of cylinders, motor size, series, and oil charge type.
Graphical Data
The document includes graphs showing performance data such as cooling capacity and power consumption across different temperatures and compressor types.
