Kirby engineered racks are specifically designed to share the refrigeration load between multiple compressors, provide supreme reliability and fail-safe operation (redundancy) in critical applications. The parallel compressor application provides optimal efficiency year-round in variable climates and changing load conditions.
Heatcraft offers an extensive range of commercial refrigeration equipment, including made-to-order Kirby Rack Systems manufactured in Australia and designed to meet Australian/ New Zealand standards. Kirby Racks are synonymous with: low maintenance, ease of installation and high performance.
Kirby Rack systems can be tailored for all refrigeration & HVAC applications, as well as all sizes, installations and refrigerants, including CO2. The platform is ideal for sites that have multiple units requiring replacement. Through peak load sharing and equalised run times on each compressor, the life expectancy of the rack system is extended.
Kirby Subcritical (R744) CO2 Racks for superior performance and longevity
The Kirby Subcritical CO2 Rack Systems are a premium package, which can be coupled with any Kirby high stage system. These systems have a proven installed base and are engineered for superior performance and longevity. Their robust, compact frame allows for fast installation and an extremely stable operating platform, with minimal vibration and noise levels.
Semi-hermetic and/or scroll compressors configured on the standard frame
Fully insulated headers, lines and components
Vertical receiver configuration allows minimal refrigerant charge and optimum liquid seal
Compressor sub-frame assembly for reduced noise and vibration
Gauge panels and pressure transducer locating points
Minimal field connections of relief points with manifold changeover for all locations to aid maintenance, saving time and money
Oil supplied for rack charging on location
Enhanced Kirby package incorporates a suction reheat system providing superior compressor protection
Superior leak testing and pressure verification process
Pressure tested with nitrogen and delivered with pressure charge for system integrity verification
Incorporated into the framework of the system is the option for an on-board air cooled economizer and auxiliary cooling unit. The parallel compression system can be configured with two, three or four compressors matched to a defined refrigeration load. The condenser configuration can be singular or multiple as determined by customer requirements.
Kirby racks can be built with Dorin or Copeland compressors. An optional pre-wired platform with integrated system control allows for “Ready to Run” configuration.
