Summary
Kiswok Industries, a leading foundry player in the cast iron segment, faced persistent challenges with unreliable compressed air dryers, resulting in casting defects and operational downtime. Delair provided a robust solution with its Refrigeration Air Dryers, delivering consistent, moisture-free compressed air. Following a successful trial, Kiswok standardized Delair dryers across multiple plants, reinforcing its long-term commitment to quality and efficiency.
About the Client
Established in 1957, Kiswok Industries is a pioneer in the foundry sector, known globally for its superior Gray Iron and SG Iron casting solutions. With a strong emphasis on operational excellence and sustainable growth, Kiswok exports high-quality cast iron products to over 20 countries. The company’s leadership is deeply committed to maintaining performance standards, ensuring that each piece of equipment used in production supports its core philosophy: high-quality output demands equally high-quality machinery.
The Problem
In the initial phases, Kiswok opted for compressed air dryers bundled with air compressors from various reputed brands. While these packages promised cost efficiency and single-point service, they failed to deliver on the most critical requirement—moisture-free compressed air.
The result was damage to pneumatically operated machinery, the formation of casting blisters and uneven layers, and a rise in the metal rejection rate, directly impacting profitability. Further compounding the issue were service delays and a lack of technical support from the OEMs during breakdowns, leading to a decline in plant reliability and uptime.
Conclusion
The partnership between Kiswok Industries and Delair exemplifies how strategic equipment upgrades, backed by engineering expertise and strong service support, can drive lasting operational excellence. For Kiswok, Delair has not just been a vendor but a trusted technology partner in its journey towards quality, efficiency, and sustainable growth.
