Revitalising Absorption Chillers with Vamtec’s Expertise

In the world of industrial cooling, maintaining optimal performance of absorption chillers is crucial for efficiency and cost-effectiveness. Vamtec, a leader in absorption chiller solutions, has demonstrated its expertise in restoring underperforming systems to peak operation. This article delves into a case study where Vamtec successfully revived a 2.5MW steam-fired absorption chiller, highlighting the company’s innovative approach and commitment to excellence.

The Challenge

Installed in 1997, the 2.5MW steam-fired absorption chiller had been plagued by various failures over the years, leading to unreliable performance. The customer faced a critical decision: replace the ageing chiller or invest in repairs. Vamtec’s intervention came at a pivotal moment, offering a cost-effective solution to restore the chiller’s functionality.

Diagnosis and Initial Findings

Upon inspection, Vamtec’s team discovered several issues compromising the chiller’s performance:

Lithium Bromide Specifications: The inhibitor and alkalinity levels were out of range, affecting the chiller’s efficiency.
Corrosion: Iron oxide and copper corrosion were found within the chiller, blocking internal heat exchangers and the spray system.
Heat Exchanger Leak: Thermal imaging revealed a leaking heat exchanger, further diminishing the chiller’s performance.

Restoration Process

Vamtec implemented a comprehensive restoration plan to address these issues:

Heat Exchanger Repair: The leaking heat exchanger was promptly repaired to prevent further liquid loss and improve efficiency.
Lithium Bromide Filtration: Over six months, Vamtec performed online Lithium Bromide filtration with chemical correction to restore the solution’s specifications.
Corrosion Removal: The team meticulously removed iron oxide and copper corrosion, ensuring the internal components were free from blockages.

Outcome and Benefits

The restoration process yielded significant benefits:

Cost Savings: By repairing rather than replacing the chiller, the customer saved a substantial amount of money.
Improved Performance: The chiller’s performance was restored to optimal levels, ensuring reliable operation.
Extended Lifespan: The comprehensive maintenance extended the chiller’s operational life, delaying the need for a new system.

Vamtec’s Commitment to Excellence

Vamtec’s success in this case study underscores its commitment to providing top-tier maintenance and repair services for absorption chillers. The company’s expertise in diagnosing and addressing complex issues ensures that customers receive the best possible solutions for their cooling needs.
