Semi-hermetic Reciprocating Compressors Tandem (60Hz, IP-Units) KP-115-2

Product catalog summary
Overview: This document outlines the technical specifications and performance data for semi-hermetic tandem compressors compatible with refrigerants R134a, R404A, R507A, R407C, and R22. It covers performance data, technical specifications, and optional accessories.
Specifications: The compressors are designed for parallel operation, enabling efficient capacity modulation by activating or deactivating individual compressors. Models with 4 and 6 cylinders can include capacity regulators for up to six capacity steps, suitable for applications with high load variations and offering energy-efficient operation at both full and part load.
Performance Data: Performance data adheres to ARI 540 standards and 60 Hz operation, considering saturated suction and condensing temperatures at dew point conditions. It highlights that zeotropic blends impact basic parameters, leading to lower cooling capacity and efficiency compared to data with liquid subcooling.
Technical Data: Detailed performance data for various compressor models is provided, including cooling capacity and power consumption. It is noted that power consumption for tandem compressors is double that of single compressors.
Optional Accessories: Depending on the series, optional accessories include crankcase heaters, oil pressure switches, integrated start unloaders, additional fans, water-cooled cylinder heads, and motor protection devices with additional functions.
Model Designation: The document explains the model designation system, detailing the coding for cylinder numbers, motor size, and oil charge type.
Conclusion: Tandem compressors offer a compact and efficient solution for applications requiring parallel compressor operation, with flexibility in capacity modulation and compatibility with common refrigerants.

Performance data Données de puissance Datos de rendimiento Performance data are based on the latest edition of ARI 540 and 60 Hz operation. Les données de puissance se basent sur un fonctionnement à 60 Hz et l'édition la plus actuelle du ARI 540. Todos los datos de rendimiento se basan en un funcionamiento con 60 Hz y en la última edición de ARI 540. Saturated suction and condensing temperatures correspond to dew point conditions (saturated vapor). With zeotropic blends this leads to a change in the basic parameters (pressure levels, liquid temperatures) compared with data based on "mean temperatures"...
