Low‑pressure UV Lamp service life ranges from 8000‑12000 hours with long replacement cycles. Lamps are low‑priced, requiring fewer replacements and lower consumable costs.
Medium‑pressure UV Lamp service life is 3000‑6000 hours, leading to frequent replacements. The unit price of medium‑pressure lamps is much higher, constituting the main cost item.
Low‑pressure UV Operating temperature is low, scaling forms slowly. Only regular cleaning is required, and the cleaning interval is relatively long.
Medium‑pressure UV Lamps work at extremely high temperatures. The sleeve surface is more prone to scaling and impurity adhesion. More frequent cleaning is needed with greater labor workload.
Low‑pressure UV Ballasts run at low temperature with low failure rates. Frequent spare‑part replacement is barely required.
Medium‑pressure UV High‑power ballasts age faster under long‑term high‑temperature operation. Equipped with air‑cooling or water‑cooling assemblies, fans and water‑circuit components need periodic inspection. Higher failure probability brings extra costs for spare parts and repairs.
Low‑pressure UV Simple operation. Routine work mainly includes regular quartz sleeve cleaning with minimal labor input.
Medium‑pressure UV Besides sleeve cleaning, cooling systems and high‑temperature components need inspection. Frequent lamp replacement consumes more working hours.
Low‑pressure UV features simple maintenance and low cost, suitable for scenarios requiring only disinfection. Medium‑pressure UV provides exclusive functions for oxidative degradation of chloramines and organics, yet higher costs for lamps, spare parts and labor shall be expected. It is widely applied in special working conditions such as public swimming pools.
