The YQW/L series represents a high-performance range of horizontal and vertical gas or diesel oil fired thermal oil boiler heaters, engineered for precision heating in demanding industrial environments. Utilizing a sophisticated wet back internal combustion two-return structure, these boilers feature an integrated top coil tube that shields the rear wall from direct flame radiation, significantly expanding the radiation heating area and maximizing overall thermal efficiency.
Designed for versatility and intelligence, the YQW/L series supports a wide array of fuels including diesel, natural gas, and town gas. With integrated automatic computer controls for DCS and remote operation, the system dynamically adjusts the burner and thermal load to meet real-time demands. This makes it an ideal thermal solution for the textile, chemical, pharmaceutical, food processing, and plastics industries where stable, high-temperature heat transfer is critical.
