Industrial fryers are cookers commonly used in
the food industry, containing large amounts of oil (up to 19000 litres
or 5000 US gallons) and operating at high temperatures. The combination
of extreme heat and fuel source creates a potential fire risk. Fire
occurs if oil reaches its auto ignition temperature (AIT), therefore
cooling the oil after extinguishing a fire is critical to avoid
re-ignition. Strict sanitary regulations and the risk of the exposure of
employees to fire and/or system discharge increases the challenges for
the selection of the most appropriate fire protection technology. A fire
incident presents major risk to business affecting operations across
the entire plant, potential loss of equipment assets and production.
The
Tyco AquaMist Industrial Fryer Protection (IFP) is a new oil cooker
fire suppression solution. The system includes watermist nozzles,
combined with fire detection to provide the best integrated solution to
protect the hood area, fine box and stacks. Of all the fire protection
options available specific to this challenge, only water mist is fully
tested by third party testing agencies like Factory Mutual (FM) with
exhaust hoods both raised and lowered.
To obtain FM approvals,
watermist must provide both full extinguishment in various dimensioned
fryers and rapidly cool oil temperatures below the AIT, minimizing the
chance for fire re-ignition after discharge. AquaMist IFP offers savings
to both owners (less downtime) and insurance companies (less downtime
and lower clean-up costs). Download the IFP brochure to see a blueprint
and quick overview of the system.
