Model Info

Rapidrop RD021 CUP QR is a conventional quick response frangible glass automatic sprinkler. It is CE marked, VdS and LPCB approved. The conventional sprinkler produces a spherical water discharge pattern. In a fire condition the heat causes the fluid in the glass bulb to expand which shatters the glass and releases the spring seal assembly. Water flows from the orifice onto the sprinkler deflector which diffuses the water into a uniform spray pattern which extinguishes or controls the fire.
