Parallel Rack Systems

A parallel rack system is a multiple compressor refrigeration unit piped in parallel to yield smooth capacity control as compared to a single compressor unit. A parallel system can be located in a back room or on a roof in close proximity to refrigeration equipment for reduced piping. PS series systems match refrigeration capacity to your actual load and can yield savings of 20% or more over a single compressor unit.

Master-Bilt PS series parallel units, matched to an appropriate condenser, may be modular allowing you to add or change compressors as needed. The standard rack housing and frame is made of durable galvanized steel with stainless steel as an option.

Features and Options

• A wide range of compressors is available, including digital scrolls, to better match capacity and budget needs while providing the most energy efficient and environmentally friendly system
• Parallel units, matched to an appropriate condenser, may be modular allowing you to add or change compressors as needed
• The standard rack housing and frame is made of durable galvanized steel with stainless steel as an option
• Optional subcooling increases refrigerant efficiency on low temp applications by approximately 17%
• Optional heat reclaim increases energy efficiency by reclaiming waste heat from the condenser
• Optional gas defrost increases energy efficiency by using waste heat for defrost
• Electronic controller units are also available on PS systems. Choose from a variety of units depending on individual requirements such as monitoring of system features, diagnostics, interfacing with existing building controls and incorporating HACCP recording
• Alarm features are also an option
