A mid-scale dairy processing plant in the Netherlands operating at 45,000 L/hr milk throughput required replacing aging tubular heat exchangers with 12 years of calcium fouling buildup. AlfaTherm installed 6 gasketed plate heat exchangers (Model AT-GP120, 316L stainless steel, 18 m² heat transfer area each) with EHEDG-compliant CIP connections. Post-commissioning thermal testing per AHRI 400 confirmed approach temperatures of 0.8°C versus the previous 3.2°C, reducing steam consumption by 22% and cutting annual energy costs by approximately EUR 48,000. Cleaning intervals extended from 8 hours to 14 hours between CIP cycles.
A 12 MW colocation data center in Frankfurt, Germany with legacy DX cooling running at PUE 1.65 engaged AlfaTherm to design a free cooling retrofit. The project deployed 8 brazed plate heat exchangers (Model AT-BPX80, 40 bar design pressure) integrated with a new glycol loop and variable-speed dry coolers. Commissioning in Q4 2023 measured PUE at 1.18 during winter months (outdoor air below 12°C) and 1.32 during summer peak. Annual electricity savings reached 2.8 GWh, corresponding to approximately EUR 420,000 at prevailing German industrial rates.
A chemical facility in Texas processing 98% concentrated sulfuric acid at 180°C experienced tube failures every 9 months on carbon steel shell-and-tube coolers. AlfaTherm engineered a replacement using 2 semi-welded plate heat exchangers with Hastelloy C-276 plates (Model AT-SW60, 25 bar design, ASME U-Stamp certified). After 24 months of continuous operation, zero plate failures were recorded. Acid outlet temperature stability improved to ±1.5°C versus the previous ±4°C variance, reducing downstream process upsets by 85%.
