Observations & Recommendations
CR - Compressor
ObservationRecommendationUnit SavingsAnnual SavingsInvestmentROIStatus
High Unloading hours for certain compressorsInstall VFD for particular compressors50,005₹2,27,523₹3000002.5
Leakage cfm is high in many machinesArrest leakages in Loom machine periodically2,00,068₹9,10,309₹100002.5
Pressure setting in looms is high around 5.5 bar. Recommended for cotton is 4.8 to 5 bar and for polyester 5 to 5.2 bar.Adjust regulator so that 0.2-0.4 bar pressure can be decreased which will give minimum 3 cfm savings per machine.81,846₹3,72,399₹02.5
HF - Humidification Plant
ObservationRecommendationUnit SavingsAnnual SavingsInvestmentROIStatus
Supply cfm is less than Return cfmRecommended Return cfm should be 95 % of supply cfm. Install VFD in return fan and optimize the speed accordingly to achieve the required supply return ratio.1,68,484₹7,66,602₹4000006.3
Return ducts of Looms are choked. It should be cleanedIt should be optimized by including VFD in Supply and Return fans.15,164₹68,996₹8000013.9
