Siddharth enterprises manufactures hollow cone spray nozzles which can provide uniform ring shaped spray pattern with wide range of 30 - 150° spray angles and 1 lpm - 2000 lpm @ 2.0 kg/cm² differential pressure flow rates. The company supplies nozzles in 2 fundamentally different swirling principles that is the axial hollow cone and tangential entry hollow cone. These axial hollow cones are further subdivided into 3 categories as spiral hollow cone, inline entry hollow cone and fine atomizing hollow cone. The fine atomizing hollow cone has a spiral groove in its swirl body to ensure an efficient rotation thereby reducing droplet size and increasing atomization. These hollow cone spray nozzles are ideal for mass heat transfer process. These hollow cone spray nozzles find applications in humidifying process in textile industry, oil atomizing, cooling, dust control, air and gas washing, spray drying desuperheating, etc.
