Solution

Natural Gas Blending & Calorific Value Control

Our precision blending solutions ensure stable calorific values for industrial users, improving product quality and energy efficiency. With ±1% flow accuracy, 30s intelligent adjustment, and multi-gas compatibility, the system adapts to steel, glass, ceramics, and city gas networks. For regions without natural gas, our LPG-air replacement technology provides a reliable alternative, already serving over 100 enterprises. All solutions meet ISO9001, NEPSI, ATEX, and IECEx standards for safety and stability.

04

Solution

Natural Gas Filtration, Regulation, Metering & Odorization

Our integrated solution ensures safe, efficient, and compliant gas transmission. With 99% particle removal, ±0.5bar precision pressure control, ±0.5–1% metering accuracy, and ±2% odorization accuracy, the system meets global industry standards while extending maintenance cycles. Ideal for city gas networks, LNG terminals, and industrial facilities.
