Hollow Cone Spray Nozzles From John Brooks Company Limited
|
Hollow cone spray nozzles are an extremely simple design that produces a high quality, small droplet size spay pattern primarily through centrifugal force. Using the design enables standard type hollow cone nozzles to produce a soft circular spray of relatively fine droplets, while having a free passage size (good clog resistance) considerably larger than flat fan or full cone nozzles of similar flow rates. Free passage size is important in applications involving solids particulate in the liquid being sprayed, such as in a recirculating water cooling pond application. Fine droplets are important in gas and other product cooling applications, because finer droplets mean more water surface area in contact with the gas or other product being cooled. Soft impact is important to minimize bounce-back and product damage in applications where a coating is being deposited onto a surface, or where delicate items such as soft fruit are being sprayed.

Standard Hollow Cone Nozzles
BJB hollowcone spray nozzles are small capacity nozzles which produce a uniform hollow cone spray pattern of fine droplets. they are available in male and female NPT pipe connection sizes of 1/8" to 3/4". Spray angles range from 60 to 90 degrees with flow rates from 0.05 to 12 gallons per minute at 10 psi.

Spiral Design Spray Nozzles
BSJJB spiral design spray nozzles are an in-line design featuring an external spiral to produce a hollow cone pattern. Droplet size is small, providing a large amount of water surface area available for cooling applications, and the unrestricted orifice gives good clogging resistance. Flow rates range from 1.4 to 1050 gallons per minute at 40 psi, with the full range being available in spray angles of 50, 120 and 180 degrees. Male NPT pipe connection sizes are from 1/4" to 4". Some sizes are available with female NPT or ANSI flanged connections to special order.
