Product Description

Upright sprinklers 

Upright sprinklers are designed for use in automatic fire sprinkler systems in accordance with NFPA 13 installation standards.

They are available with standard-response 5 mm or fast-response 3 mm glass bulbs and feature a compact, durable construction. Multiple finishes and temperature ratings are offered to suit various application needs.

The sprinkler body is manufactured from DZR brass forged copper alloy, providing excellent strength and corrosion resistance. The spring seat uses a Belleville washer, coated on both sides with T eflon, ensuring stable and reliable performance.

Pendent, conventional, and sidewall sprinklers can be installed with adjustable or non-adjustable escutcheon plates, suitable for finished ceilings and walls. Adjustable escutcheons allow for easier installation and a clean appearance, especially in areas with completed interior finishes.
