    Medium Velocity Water spray

                Size ½ ″ to 1" NPT

APPLICAT ION

   The Model 7020 spray nozzles are open (non-automatic) directional spray nozzles and are designed for use in water spray fixed systems for fire protection applications. They are external deflector type nozzles that discharge a uniformly filled cone of medium velocity water droplets.

The 7020 Nozzles are effective in covering exposed vertical, horizontal, curved, and irregular shaped surfaces in a cooling spray to prevent excessive absorption of heat from an external fire and possible structural damage or spread of fire to the protected equipment.

The Type 7020 nozzles are available in a wide variety of orifice sizes and spray angles (included angle of discharge) to provide versatility in system design.

These spray nozzles are using in off-shore platforms, Refineries, Power Station, LPG & LNG Plants, Spherical Tanks.

 

FEATURES AND BENEFITS

Minimum Flow Rate of Spray Nozzle:

The minimum flow rate of each spray nozzle with different K-Factor determined with following equation:

 

Flow (Lpm) = K-Factor ´

P =Minimum pressure = 1 Barg. (Recommended)

The range of pressure = 1.0 to 5.0 Barg.

Recommended Pressure 1.5 to 3.5 Barg.

 

D =Spray Distance from wall side

Theoretical Coverage Distance  = (2×D) × Tan(α )

B=Wet Coverage Distance = 0.8(2×D) ×Tan(α )
