While working on a sprinkler project I came across a Spiral Freezer. It is a conveyor system.  Rendering of a two-level Spiral Freezer Conveyor System. I am mostly interested in how it needs to be protected. At this time I see two and neither have protection within the Freezers. This facility is not new, but I know they are upgrading the fire protection throughout.

I've done a few of these for a client insured by FM. We protected all the floor space around the conveyor portion, including beneath the service platforms. Nothing was put inside the spiral conveyor itself.

I have not encountered one of these systems specifically but overall I would think the conveyor system would be considered equipment and non-occupiable space. Therefore, I don't feel it would need protection unless requested for specific property protection/insurance reasons, not general life safety.

I worked on a bakery that had two of them and we considered it a piece of equipment classified as a non-occupied space.

Is there access into the freezer if product falls off conveyor?? I would put dry sidewall sprinklers through the wall of the freezer aimed at what appears to be the open part of the conveyor system. Two levels?, Number of sprinkles dependent on width of freezer.

Usually this type of equipment has associated equipment such as motor. So best way to protect the motor is by deluge water spray system in compliance with NFPA 15.

John - can you explain this more? Do you use a NFPA 15 system to protect all motor installations? Is this a general FM requirement or only a conveyor requirement. Leave a Reply. |
