Fogmaster Sentinel® 5855 1/2HP, 1-316SS Nozzle Fogging System

The Sentinel 5855 systems uses one or more Sentinel nozzles attached to a low pressure air manifold to atomize a liquid into small droplets. Nozzles can be pipe-mounted or hose-mounted. 

The controller, with several control options, regulates fogging activity, are available. These include a one-shot countdown timer, programmable 7-day timer and repeating cycle timer; humidity sensor/controller; or customer-supplied external device - anything that can close a switch (manual, contact, PLC, process controller, etc.).

The Sentinel nozzle creates a highly turbulent zone, dices liquid into droplets, and ejects it as a fast moving fog plume. Droplet size is adjustable, from less than 5 microns VMD to more than 40 microns.

This method ["cold fogging"] does not require high pressures, small orifices or hot surfaces for atomizing liquid. It works with both water- and oil-based liquids, and can atomize light suspensions (finely divided solids dispersed in a liquid carrier). And since the Sentinel nozzle has no small orifices, plugging is not a problem.

Nozzles are available in several materials. The standard nozzle uses Celcon® acetyl copolymer for internal elements; for fogging strong oxidizers, such as hydrogen peroxide and glutaraldehyde, HPDE elements are preferred; and for work in high temperature environments or involving erosive materials, nozzles are available in 316 stainless steel.

Fogmaster Sentinel 5855 Product Literature

Applications   Uses of the Sentinel 5855 system include:

  • Odor control at composting facilities, sludge drying sheds, septage receiving areas, lift stations, wastewater treatment plants, exhaust stacks, and so forth; 
  • Fogging of chemical sanitizers or disinfectants in clean rooms, agricultural production facilities, and, with a hose-mounted nozzle, treatments to ambulances, school busses, vans, shipping containers; 
  • Pest control (production agriculture, food products storage, warehouses); 
  • Production processes needing to atomize liquids or suspensions;
  • Other atomizing applications with heavy duty-cycles and/or repeat cycle frequency. 

Cart Mounting / Portable Applications  For applications requiring portability, the 5855 can be mounted on a 2-wheeled cart. This carries controller, pump, blower (max size: 1.5 Hp), and one or two nozzles (pipe or hose mounted). 

Liquid Supply  The Sentinel 5855 can use a pump to supply fogging liquid from a pail, drum or tote. It can also draw from a solenoid valve to an elevated tank or water line. The carrier liquid can be premixed to the final dilution, or mixed in-line by a 5250 proportional injector. 

The control module includes relay contacts to open the valve or activate a supply pump. Although any type of pump can be used, peristaltic pumps are often preferred. They are self-priming, available in the low GPM ratings used in fogging, and often have variable output drives. 

A white paper, Liquid Supply Considerations for Sentinel® 5855 atomizing systems, provides useful background information on selecting equipment and designing the supply piping. 

MotorBrushless, capacitor-start. Explosion proof motors optional.
BlowerExternal regenerative blower, 1/2 Hp and up. Blower size is determined by the number of nozzles supported (per zone). Typically cast aluminum housing. Motor drive: usually shaft-mounted; V-belt drive available. 
NozzlesOne or more nozzles. Nozzles are available for mounting directly to the air supply pipe, or on a 15 ft hose with cam-lock fitting to attach to air source. Pipe-mounted nozzles offered with PVC union connection, or 1-1/2" NPTF. Fog discharge angle and direction is adjustable. 
Nozzle Technology

Counter-rotating vortex design. High turbulence in nozzle shears feed liquid into fog-sized droplets (5-50+ micron VMD). Liquid viscosity, surface tension, density and liquid feed rate affect droplet size. 

Nozzle is immune from plugging (minimum orifice approximately 1/8") and can be used to atomize liquids with suspended solids or light slurries. 

Particle Size,
microns
4-50+ µ, adjustable. 
Liquid SupplyLiquid supply options include pump, gravity feed (elevated tank), or the local water system (in-line dilution with proportional injector). Liquid flow rate (per nozzle) is typically 0-20 oz [600 ml] /min, but flows up to 50 oz/min are used in some applications .
Liquid Flow ControlLiquid flow to each nozzle is controlled individually. This ensures proper distribution of liqud and control of droplet size at each point. A flowmeter (rotameter) with integral needle valve is normally used, but variable speed pumps are also available. 
Fogging LiquidsWater. Water-based chemicals. Oil-based chemicals. Suspensions. Light slurries. 
PortabilityCart option available for smaller systems [0.5 to 1.5 Hp].
