Product Formation

This sprinkler head (Model: TY4131/TY4231) features a dual-mount design—it can be installed upright (for exposed industrial pipes/ceilings) or as a pendant (for commercial/residential spaces), fitting diverse layout needs. As a quick-response unit, its heat-sensitive element triggers rapidly at 68℃, enabling early fire control to minimize spread, ideal for high-traffic areas like malls, offices, or residential buildings.

With a K115 flow coefficient, it provides high water output (115 liters per minute under standard pressure) to cover larger areas effectively. Crafted from durable brass or stainless steel, it resists corrosion and operates within -20°C to +60°C, complying with industry fire safety standards for long-term reliable performance.

Product Features

1. Model-Specific Reliability

The TY4131/TY4231 is engineered for outstanding model-specific reliability, critical for early fire intervention. It undergoes strict production testing to ensure consistent quick-response performance. This reliability enables it to detect and respond to incipient fires (e.g., smoldering materials, small flames) without delays or fluctuations. Maintaining stable functionality even during checks or low-activity periods, it serves as a dependable first line of defense, minimizing fire escalation for effective early suppression.

2. Flexible Installation

With a dual upright/pendant design, the TY4131/TY4231 offers excellent installation flexibility for diverse spaces. Upright mounting suits high-ceiling areas like industrial warehouses and large commercial halls, ensuring unobstructed water distribution. Pendant mounting is ideal for standard-height spaces (residential rooms, offices, retail aisles) with direct downward coverage. Equipped with standardized mounting interfaces, it integrates easily with existing fire systems across industrial, commercial and residential settings, reducing installation time and labor costs.

3. Rapid Activation

Featuring a precision thermal activation mechanism, the TY4131/TY4231 is calibrated to activate rapidly at 68℃. When ambient temperature reaches this threshold due to early fire, its thermal element responds in milliseconds to initiate water discharge. This ultra-fast activation suppresses flames before they spread, significantly reducing property damage and life risks—an essential advantage for early fire control.

4. Strong Coverage

The TY4131/TY4231 delivers powerful water output via its K115 flow coefficient, ensuring strong, wide-ranging coverage. The K115 rating provides a consistent high-volume stream that eliminates protection gaps, efficiently covering large areas like industrial workshops, open-plan offices and spacious residences without extra units. Its powerful discharge extinguishes flames quickly and cools surfaces to prevent re-ignition, ensuring comprehensive suppression.

5. Durable Build

Constructed from high-quality brass and stainless steel, the TY4131/TY4231 boasts robust corrosion resistance for long-term durability. Brass resists rust and corrosion, while stainless steel enhances structural strength against impacts and wear. Rigorously tested to operate in -20°C to +60°C, it adapts to extreme environments from cold storage to tropical industrial plants. This durability minimizes replacements and repairs, lowering long-term maintenance costs while ensuring consistent performance.
