2025 has witnessed a new round of policy upgrades and technological iteration in the high-purity water preparation industry, driving the rapid development of tubular multi-effect distilled water machines. The Pharmacopoeia of China 2025 Edition has broken the monopoly of distillation process for water for injection, adopting a result-oriented supervision model while tightening water quality standards: the microbial limit of water for injection is reduced to ≤5 CFU/100mL, and real-time monitoring of key indicators such as endotoxin and conductivity is mandatory. The newly revised GMP has further standardized the whole-life cycle verification requirements for water systems, including DQ, IQ, OQ and PQ, and required the integration of energy efficiency verification reports into the annual self-inspection scope, forcing the upgrading of old equipment.
Benefiting from policy guidance and the rapid development of the biopharmaceutical industry, the market scale of tubular multi-effect distilled water machines in China is expected to reach 389 million yuan in 2025 with a CAGR of 8.2%. The proportion of high-energy-efficiency models with more than 5 effects has exceeded 65%, and the maximum single-unit capacity has been upgraded to 20 tons/hour. Technologically, the equipment is moving towards intelligence and energy saving: the integration of MVR technology reduces steam consumption by 40%, and the embedded IoT remote monitoring system realizes real-time tracing of water quality data. The localization substitution process is accelerating, with the market share of domestic leading brands exceeding 65%, and the modular design shortens the equipment delivery cycle by 40%.
Driven by the industrial water-saving policy, the coupling of tubular multi-effect distilled water machines with energy-saving and emission-reduction technologies has become a new trend. As a core equipment for high-purity water preparation in biopharmaceuticals, high-end laboratories and medical device manufacturing, it is playing an increasingly important role in helping enterprises achieve compliance production and green development.
