Fogmaster Sentinel 5855 1HP, Dual HDPE Nozzle Fogging Package

Fogmaster Sentinel® 5855 1HP, Dual HDPE 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.
