Industrial Chiller for Printing Process Cooling
A major printing company in Shanghai faced long-term challenges with heat generation in its core UV printing and web printing processes, adversely affecting production efficiency and print quality. KANSA leveraged professional expertise to establish a strong collaboration, providing customized precise cooling solutions to effectively resolve the company’s process cooling issues.
Six UV curing lamps generated substantial heat during operation, accelerating lamp aging and causing uneven ink curing, increasing maintenance costs and compromising print quality.
KANSA configured a 15 HP chiller with a rated cooling capacity of 44kW, utilizing a closed-loop cooling system to precisely control the temperature of the UV lamps.
Lamp failure rates decreased significantly, replacement frequency reduced, and maintenance costs dropped. Ink curing uniformity improved, increasing the print pass rate from 92% to 98%, and product quality stability was markedly enhanced.
Eight medium-sized web printing lines experienced roller temperature fluctuations due to frictional heat and heated ink, causing increased registration errors, high paper waste, and lower material utilization.
Each web printing line was equipped with a dedicated 5 HP chiller (rated cooling capacity 17.5kW) with a dedicated cooling loop, maintaining roller temperature around 25°C.
Stabilized roller temperatures significantly reduced registration errors, improving print accuracy. Paper waste decreased, material utilization increased by 6%, and overall production loss costs were effectively reduced.
