CASEN Heat Transfer Unveils NextGeneration Green Cooling at Indonesian Pharmaceutical Plant

Surabaya, Indonesia – May 2025 — CASEN Heat Transfer Technology Co., Ltd. has partnered with one of Indonesia’s foremost pharmaceutical manufacturers to commission two of its advanced stainlesssteel evaporative condensers at a newly inaugurated sterile injection facility outside Surabaya. Engineered for peak performance in tropical climates, the installation delivers precise temperature control, remarkable energy savings, and entirely chemicalfree operation—setting a new benchmark for sustainable industrial cooling.

Precision Cooling for Critical Processes

In pharmaceutical production, even minor temperature fluctuations can compromise product integrity. Faced with the challenge of maintaining sub10 °C chilled water under continuous high load conditions, the plant’s engineering team turned to CASEN’s proven evaporative condenser technology. Since startup, the system has held chilledwater temperatures at a consistent 9 ± 1 °C, ensuring a stable, GMPcompliant environment for sensitive sterile fill operations.

Engineered for Reliability and Efficiency

CASEN’s evaporative condensers are built from 100 % 316L marinegrade stainless steel, offering unrivaled resistance to corrosion and fouling. Unlike conventional units, these condensers feature CASEN’s proprietary WaveMesh fill media, which expands the evaporation surface by 15 %, driving faster heat removal while minimizing footprint.

A key differentiator is the zerochemical water treatment approach. By harnessing filtered river water and recapturing over 99.995 % of drift, the system eliminates harmful discharge and extends maintenance intervals—requiring just two washdown cycles per year. Intelligent PLCbased controls provide realtime monitoring of flow, temperature, and water quality, enabling predictive maintenance and uninterrupted operation.

Tangible Benefits, Immediate Impact

·Energy Reduction: Over 20 % annual electricity savings compared to traditional aircooled systems

·Space Optimization: Roofmounted design liberates valuable floor area for production

·Operational Simplicity: Biannual servicing and remote diagnostics slash downtime and labor costs

·Environmental Stewardship: Zerochemical cooling and ultralow water loss uphold sustainability goals

·Quiet Performance: Vibrationisolated mounts and acoustically tuned fans keep noise below 68 dB(A)

Plant management reports that, in the first quarter postinstallation, the condensers delivered seamless performance through peak ambient wetbulb conditions, with no unplanned interruptions or waterquality issues.

A Model for Sustainable Industry

This project exemplifies CASEN’s mission to drive greener, more efficient cooling across industries. With installations now supporting electronics manufacturing, food processing, precision machinery, and pharmaceuticals throughout Southeast Asia, CASEN continues to lead the transition toward sustainable process cooling—combining cuttingedge materials, innovative design, and digital intelligence.

“Partnering with CASEN has transformed our cooling strategy,” said the plant’s Engineering Director. “We now enjoy stable process temperatures, lower energy bills, and the confidence of an ecofriendly, lowmaintenance system—exactly what our growing production demands.”
