Product Description
Horizontal Sidewall Series Sprinklers are a specialized type of sprinkler head designed for installation on walls or side surfaces, with a horizontal spray pattern (parallel to the mounting surface) that covers a fan-shaped or semi-circular area. These sprinklers are typically used in spaces with unique layouts where traditional pendant or upright sprinklers cannot be installed, such as narrow corridors, room edges, or areas with limited ceiling height.

Classification of Sprinkler Heads and Corresponding Applications
Sprinkler heads can be categorized based on installation method, spray direction, response speed, and special functions:
By Installation Method
| Type | Characteristics | Applications |
| Pendant | Nozzle faces downward, installed below piping, sprays water vertically downward. | Standard ceilings (e.g., offices, hotels, malls), areas requiring full coverage. |
| Upright | Nozzle faces upward, installed above piping, water deflects off a disc downward. | Exposed ceilings (e.g., warehouses, parking lots), areas with obstructions. |
| Sidewall | Mounted horizontally on walls, sprays water in a fan-shaped pattern. | Narrow spaces (hallways, stairwells), irregular or low-clearance ceilings (e.g., basements, residential areas). |
| Concealed | Recessed into the ceiling, only the thermal element is visible (aesthetic design). | High-end hotels, residences, and finished interiors. |
2、By Response Speed
| Type | Response Time | Applications |
| Standard Response | Slower (RTI ≥ 80) | Low-to-moderate fire risk areas (e.g., offices, classrooms). |
| Quick Response (QR) | Faster (RTI ≤ 50) | High-occupancy spaces (hospitals, nursing homes), early fire suppression. |
| ESFR (Early Suppression Fast Response) | Ultra-fast, high flow rate. | High-hazard storage (e.g., plastics, cardboard warehouses). |
3、By Coverage Type
| Standard Coverage: | Suitable for most general applications. |
| Extended Coverage: | Covers larger areas, reducing the number of sprinklers needed (e.g., large warehouses). |
4、Specialty Sprinklers
| Dry-Type Sprinklers: | Used in freezing environments (e.g., cold storage), pipes filled with air/gas to prevent freezing. |
| Pre-Action System Sprinklers: | Require dual activation (smoke detector + heat sensor), used in water-sensitive areas (data centers, museums). |
How to Choose the Right Sprinkler Head?
Evaluate Space Layout
Ceiling height and type (e.g., drop ceiling, exposed).
Obstructions (e.g., beams, pipes) that may affect water distribution.
Narrow or irregular spaces may require sidewall sprinklers (e.g., Horizontal Sidewall Series).
Assess Fire Risk Level
Low-to-moderate risk (offices, homes): Standard-response pendant or sidewall sprinklers.
High fire load (warehouses, kitchens): ESFR or quick-response sprinklers.
Environmental Conditions
High-temperature areas (boiler rooms): High-temperature-rated sprinklers (e.g., orange or red glass bulb).
Freezing environments: Dry-type or antifreeze sprinklers.
Aesthetic Requirements
Finished interiors may use concealed sprinklers.
Compliance
Follow local fire codes (e.g., NFPA, GB standards) and architectural requirements.
Example Applications
| Hotel Hallway: | Horizontal sidewall sprinklers (space-saving, aesthetic). |
| Warehouse: | ESFR upright sprinklers (rapid suppression for high fire loads). |
| Data Center: | Pre-action system + quick-response sprinklers (water damage prevention, early suppression). |
