Many pharma & fine‑chemical plants upgrade old photoreactors by simply swapping light sources, adding controls or retrofitting explosion‑proof components. Partial hardware replacement often brings unexpected risks: safety non‑compliance, poor reaction performance, incompatible subsystems and poor return on investment.
⚠️ Four frequently‑overlooked retrofit risks: ✅ Light‑field mismatch after lamp replacement Reactor geometry is tuned for legacy light sources. Installing new UV‑LED directly disturbs internal light distribution, shifting conversion & selectivity for high‑value pharma intermediates.
✅ Superficial explosion‑proof modification Replacing only explosion‑proof electric parts ignores risks inside chambers, wiring cavities and cooling‑medium leakage. Real explosion safety demands full‑system evaluation, not just component‑level changes.
✅ Disconnected old & new control logic Incompatible PLC / sensor protocols break interlock protection. Temperature, pressure & exhaust data cannot be linked for timely risk response.
✅ Unaddressed corrosion‑induced secondary failures Aged seals, flanges and vessel walls suffer corrosion damage. Ignoring these weak points leads to leakage and quartz contamination, interfering with photochemical reactions.
Retrofits require holistic assessment covering media properties, light‑field distribution, explosion‑proof interlocks and corrosion resistance, rather than piece‑part upgrades.
PRST UV delivers full evaluation & adaptive retrofit solutions for existing photochemical equipment. We review light‑field performance, safety interlock logic and corrosion conditions for your process.
