Premium All-Copper ESFR Fire Sprinkler Nozzle With Early Suppression Rapid Response Technology In Upright Config Featuring Fusible Alloy Link And 202 Degree Celsius Rating For Serious Commercial Protection Totally Badass And Built To Last

Single Pack Upright Copper ESFR Sprinkler for Retail
✔️ K202 Coefficient 20mm Diameter R3/4 Thread 68C Fuse

This single pack upright fire sprinkler head delivers rapid water discharge the moment heat triggers its alloy link. Designed primarily for warehouse aisles and mezzanine ceilings, it directs a focused downward spray while catching overhead flames. The robust copper body withstands high system pressures while resisting corrosion in commercial and light retail environments.

✅ All copper construction resists rust and thermal stress
✅ K value of 202 ensures optimal flow volume under pressure
✅ R3/4 threaded base fits standard fire branch pipe routing
✅ 68 degree celsius sensor activates during early fire stages
✅ Downward parabolic spray handles shifting cargo zones well

💡 What determines the right heat rating for a commercial fire suppression system?
Picking the correct thermal fuse setup keeps your coverage sharp without triggering false discharges.
- Installing this model proves handy for straightforward branch pipe setups
- Heavy storage bays benefit from rapid response kinetics plus accurate droplet spread
- Solid copper shells channel thermal energy directly to the fusible pellet every time
