Customer Overview
A leading yarn dyeing company based in Bangladesh produces dyed cotton, synthetic, and cotton-synthetic blended yarn as well as sewing and embroidery thread for the export-oriented readymade garment (RMG) industry. It has an annual production capacity of 4,200 MT.
The Challenges
The company struggled with several challenges related to their pump systems:
- Aging Pump Infrastructure: The existing pumps were old and consumed more energy than necessary.
- Incorrectly Sized Equipment: Most of the pumps were sized incorrectly, leading them to run on inefficient operating points
- Lack of Efficiency Monitoring: There was no method in place to identify the efficiency of individual pumps.
- Invisible Energy Costs: The company had no visibility into the energy costs associated with each pump.
- High Operational Costs: Due to unknown pump efficiencies and the lack of digital continuous monitoring, the company faced escalating energy costs.
Energeia’s Solution: Comprehensive Pump Audit
To address these challenges, Energeia conducted a thorough pump audit across the company’s operations.
Pump Audit Implementation
The audit focused on various types of pumps within the facility, including:
- Hard Water Pumps
- Softener Pumps
- Generator Cooling Water Pumps
- Cooling Water Circulation Pumps
- Submersible Pumps
Key actions taken during the audit included:
- Monitoring Key Metrics: Power consumption, flow rates, discharge pressure, and head were monitored for each pump to establish a baseline for efficiency.
- Efficiency Assessment: Over 42 pumps were identified as running at 40% efficiency or less, highlighting the need for immediate action.
- Order and Implementation: The audit led to the customer placing an order for 52 new pumps, each properly sized and designed by Energeia to meet the specific needs of the operation.
- Documentation and Reporting: Energeia provided comprehensive documentation and reporting throughout the process.
- Monitoring and Verification: Post-installation, Energeia monitored and verified the savings achieved, establishing a new baseline for energy consumption and performance.
