The Shilla Fire SL-26 Series represents a premier lineup of handwheel gear-operated stationed firefighting monitors engineered and manufactured by Shilla Fire Co., Ltd. (Korea). The complete industrial catalog encompasses all nine certified heavy-duty models: SL-26N, SL-26B, SL-26A, SL-26G, SL-26AB, SL-26GB, SL-26HM, SL-26NES, and SL-26HE. These master stream firefighting appliances are frontline defense solutions deployed across large crude oil storage tank terminals, petrochemical refineries, dockside fire towers, marine response vessels, and industrial fire apparatus.

A defining technological feature of the Shilla Fire SL-26 Series is its fully enclosed worm gear transmission system (Enclosed Worm Gear Drive), operated by dual independent cast handwheels for horizontal rotation (360° continuous) and vertical pitch (-45° downwards to +85° upwards). The precision-machined worm gear drive provides an intrinsic self-locking capability that neutralizes hydrodynamic recoil and vibration forces generated during maximum water or foam discharges up to 2,000 GPM (7,600 LPM). This mechanism enables the operator to adjust targeting trajectories with minimal manual effort and ensures that the discharge direction remains positively locked on target without drifting.

The SL-26 Series is tailored into distinct structural configurations and material choices:
1. SL-26N / SL-26B Series: Streamlined single waterway configuration available in Hard-Anodized Aluminium or Cast Bronze. Model SL-26B incorporates an integral built-in lever isolation valve directly at the inlet flange for rapid line shut-off.
2. SL-26A / SL-26G / SL-26AB / SL-26GB Series: Dual-waterway balanced geometry cast from heavy Bronze ASTM C83600 (SL-26A) or high-strength Ductile Cast Iron with Brass swivels (SL-26G). The dual flow channels balance internal reaction forces, reducing turbulence and pressure drop. Models SL-26AB and SL-26GB feature integrated isolation valves.
3. SL-26HM / SL-26NES / SL-26HE Series: Specialized high-performance units. Model SL-26HM features expanded 3" to 4" waterways for high-volume master stream applications up to 2,000 GPM; Model SL-26NES is constructed entirely from Stainless Steel (SUS304/SUS316) for chemical and marine salt corrosion resistance; and Model SL-26HE provides an extended vertical elevation profile optimized for aerial apparatus and elevated monitor towers.

Coated in a UV-resistant Fire Red Epoxy Powder Finish, the SL-26 Series ensures dependable performance in demanding industrial and marine environments.
