VARIFLO® - RETURN FLOW NOZZLES

For good atomisation over a wide flow range.

Allows various burner output based on by-pass pressure.

Wider spray anges at lower flow rate.

Less subject to clogging.

The Siphon Type SNA Air Atomizing Nozzles are primarily used for extremely fine spray particle sizes at low air pressure. This type of nozzle produces a solid cone spray pattern with extremely fine particle size at low air pressures and low CFM. The nozzle will flow in either a horizontal or vertical position

Spray caracteristics.

For good atomisation of both light and hevy oils at higher flow rates.

Covers a wide range of throughputs from 10GPH (32 kg/h) up to 200 GPH (720 kg/h)

• Fine atomisation of many liquids that cannot be atomised by hydraulic pressure alone.
• Uniform solid cone. Spray angle varies with air pressure and flow. Separate metering device, such as orifice, metering pump or valve required.
• Large flow passages greatly reduce clogging.

The all-new Delavan ProTek® Nozzle System provides the first step into the future of Clean Air Technology®. This unique, patented System from
Delavan provides significant reductions in combustion pollutants for cleaner air. The ProTek Nozzle System includes a factory-installed, one-piece Valve Component which reduces smoke and oil smell in the off cycle by preventing oil after drip from the nozzle. Also, the reduction of smoke (carbon and soot) helps maintain burner set up efficiency longer and extend the time period between appliance clean ups. Installation is fast and easy; there’s no need to increase pump supply pressure at installation because there’s no pressure drop. Plus, ProTek Nozzle Systems maintain the same flow pattern and flow rating characteristics of comparably rated Delavan nozzles. The dramatic benefits of the ProTek Nozzle System are available in either a factory-installed, complete system or as the ProTek Valve Component sold separately to replace the standard filter on a Delavan nozzle.

Hydrocarbon emissions are greatly reduced when the Delavan ProTek® Nozzle System is used. Hydrocarbons are typically elevated at start-up and shut-down of the nozzle firing, as both of these graphs show. When the ProTek Nozzle System is installed, the dramatic benefits are seen in these charts which show comparative results with and without the ProTek® valve. Results will vary by application.
