Case Studies
Dairy company optimizes operations with Copeland™ refrigeration scroll solution
Background
Accurate and consistent processing temperature is a key parameter that impacts quality, taste, texture and shelf life of dairy products. An Indian milk processing company needed to upgrade its large-scale commercial refrigeration system suited for warm tropical climates.
Challenge
A milk processing unit in Southern India needed a refrigeration system for curd blast chilling application. The unit faced inconsistent curd quality, high energy bills and space constraints. Loud noises also emanated from its existing refrigeration system, disrupting adjacent facilities. Pragya Refrigeration, contracting partner, turned to Emerson for optimum refrigeration solution.
Solution
Emerson India manufactured air-cooled condensing unit (KHZ622PAL) with Copeland ZB large scroll compressor:
- O20% lighter than previous system
- Minimal noise and vibration
- 50kW cooling capacity
- R404A refrigerant
Result
Working together with Pragya Refrigeration, Emerson enabled on-time delivery and facilitated installation of the air cooled condensing unit achieved:
Reduced monthly energy bills by 6-7%
Space savings from rooftop installation
Enhanced efficiency by up to 10%
Low noise and vibrations
Decreased carbon footprint
Sustainable long-term solution
The refrigeration solution projects a payback period in less than 5 years for the initial CAPEX with the Copeland ZB scroll compressors versus semi-hermetic compressors.
