Water wash parts

I will forward this information to our Gaylord service tech. He is currently in Moscow Russia training a new kitchen exhaust cleaning company; he will be back in the office Tuesday. He will have a better idea of where to direct you.

Sorry for any delay,

(Copied and pasted from my other post concerning wash water systems)

In my 15 years of servicing restaurant hood sytems I have never seen a wash water hood system that is worth its weight in grease.

Problems I see with wash water systems----->:eek:

The nozzles only clean in a set direction, the rest of the area is not reached by the nozzzle becomes contaminated

Once the chemical resevoir runs out it is rarely if ever refilled on a reasonable basis.Then you have nothing but water pushing grease and contaminents around inside the hood over the cooking area.

All the contaminents that are removed by the nozzles end up laying in the bottom of the track. Wich in turn accumulates and creates bacteria.

The drains are usually plugged at one location or another be it at the beginning of the track or somewhere in the pipe along the drain system.

They break down and do not get repaired.

I have heard many times. We have a wash water hood system ,We do not require a hood cleaning service. Then I proceed to show them what the interior of the hood looks like. I get alot of EWWW Yuck thats nasty.
Then I proceed to explain to them how it only cleans the area in front of the nozzles and not the Filters the Plenum the Duct of the Fan.

In fact those with wash water hoods need to be in contract with a experienced hood service as to avoid bacteria build up and a serious fire hazard.

So- in conclusion, Explain the down falls of the system and sign them up for a regular service. It would be benficial to there environment and your business.

In my opinion the wash water hood sytems should be replaced with a regular Type 1 Hood with out any wash water system.

Oh and get the part, not that its going to actually clean the hood but if they want to pay you to fix something thats obsolete then have at it.
Just my 2 cents. Cheers GOAT.
 
You can pick up parts from ACT at 847-343-4789-Shawn Corbett. Or you could call me and I can get them. Call Shawn.:)

Thanks.

I have tried calling them (Gaylord) for the past 3 days but get voicemail after voicemail; how frustrating.

Do you happen to know if they have service techs scattered about the USA? Or if they sub their work out?

I'm in a bind trying to get someone to look at it. If the system can't be fixed it will be a simple process of adding a $5,000 suppression upgrade to the hood. I'd just like to know if it would be less expensive to fix what they have instead of having to add more pipes and tanks.

Again, thanks.
 
At one time Gaylord did service some of their systems, but now they refer you to a distributor. If we knew where you were located, there might be a close by distributor.

I don't think the water wash meets UL300. If a UL300 system is added, contact the suppression system mfg and ask about the interaction of the water wash and the chemical suppression system. Specifically you are interested in what happens when the suppression chemical is diluted. Also ask if the water wash chemical will corrode the corner pulleys. If the corner pulleys are corroded by contact w/the G50, you should considor an Amerex system as their Pneumatic detections system will not corrode. Ask the Gaylord people if your water wash meets UL 300. If they say it does meet UL 300, ask for that statement in writing. A couple of years ago, I installed a UL 300 fire suppression system in a local hospital and my research indicated the Gaylord water wash did not meet UL 300, the need to shut off the water wash in case of fire and not to use corner pulleys for the detection system. We installed an Amerex System, the customer was very pleased.

You can remove the water wash, put in Your RFP " Fire suppression systemto meet NFPA 17-2002, NFPA 17A-2005. NFPA 96-2004." Also add whatever code your state or local jurisdiction claims to use.

Thanks for the reply.

I was under the impression that a water wash can take place of a fire supression system (NFPA 96 2004 - 10.2.8.1). If the water wash isn't working (or in place) nozzles would have to be ran into the plenum and duct areas.

And, as NFPA would have it, they leave the UL 300 compliance open ended with something like "...UL 300 listed or other equilivant standards..." for the water wash system.

I hate the 20+ "books" from NFPA. I don't think NFPA 96 should discuss NFPA 10, 13, 17, etc... in detail, it should only say "Be in compliance with NFPA 'X' and / or 'XX' (as well as XXX :) ) and not go into details about it. :rolleyes:

Anyway, I am just about past even getting the Seco unit repaired; what a pain the the butt. I'm shooting them a proposal for the last two Ansul tanks to go to UL 300 and repipe the entire system to cover the plenum and ducts (as well as add links above all cooking equipment :rolleyes: ) and add Class K's, etc..... That will solve a ton of problems and ensure that there is no future needs on the water wash system (chemicals, repairs, etc). Since it sucks trying to pipe into such small areas, I always hire some 10 year old's with small arms / hands :D

It will cost them about $10,000 but in the end, I think they will be happy. Heck, at least they don't have to replace their 48' hood @ $1,200 per foot :D
There is always a happy ending.
 
Well your question raises more questions.

The reason NFPA calls for a "UL 300 or other equivilant standards" is NFPA only says what standards must be met, NFPA does not set standards, but does refer to other agencies standards. If another testing agency developes a standard that meets UL 300, that standard can be used. UL 300 does not specify a particular brand, chemical, or method to control a grease fire. UL 300 just specifies what the criteria and result must be. If you can desgn a fire suppression system that uses warm spit, and it controls the fire, you are in business. Further, The changes that UL 300 brought about concern the appliances only. Duct and plenum coverage have remained the same. For a good example, look at the pre-UL 300 R102 duct and nozzle coverages. They have not changed. but the appliance protection has changed. At an Ansul class I attended, we were told that we could leave the R101 in place for duct and plenum protection, until factory support and parts were not available. R-G changed the appliance nozzles and now use 3/8 pipe for nozzles. the old 1/2 inch duct and plenum nozzles can still be used.
So to get back to your question about the water wash. If you have a water wash that works, and is/was listed for duct and plenum, use it. But I do not think you can add a water wash to a hood. Gaylord did use EA-1 sprinklers from Grinnel for applaince protection. The EA-1 head was listed for use over appliances, including fryers. But the head did not meet UL300, so Grinnel voluntarily de-listed the EA-1 head. At this time the only way to meet UL 300 is to use a liqued system from Ansul/Pyro Chem; Amerex, or Range Guard/Badger.

NFPA 96-2004 Chapter 2 does list referenced publications for a reason. By referencing the other standards, such as NFPA, UL, EPA, ASTM, ANSI/ASME and MSS, NFPA does not need to print a much larger book. And do not forget what happens when NFPA references another NFPA code. If a jurisdiction adopts a NFPA CODE, that referenced code then becomes part of the original code. If your local FM adopts NFPA 96- 2002 in its entirety, then any referneced codes become part of NFPA 96-2002. That is why when I mention a NFPA code I add the year. If only parts of a NFPA code are adopted, the referenced codes may not apply.

How many tanks will your 42 foot hood have? Are you going to manifold any of them together?

Are you going to gain access to the duct/plenum through the existing access panels or are you going to add more access panels?
