Are KSB pumps UL listed. Second, should I go for a split case or end suction (horizontal) for delivering 750gpm in a fire sprinkler network. Thanks

It is 18000cfm AHU and I have been installing attenuators in my previous designs in the supply air ducts. Looks like you are right, these are mostly customized built AHUs which have...

I have looked few catalogs, Carrier, Trane for instance but don't find any attenuators inside the AHU.

Are there any such AHUs avialable which have built in sound attenuators. Meaning inside the AHU body, immediately after the blower fan...there is sound attenuators. Thanksj

What should be the approximate height of a supply air duct inside a warehouse whose side walls are 6 meters high and racks for storing goods would be 5 meters high. I am more interested in knowing...

Thanks 2sak

@Alcomech - pre insulted pipes are not in much use here. Usually it's the PVC or Carbon Steel that we use for the embedded lengths of pressure pipes.

Does an underground chilled water pipe entering a building through grade beam or a wall require any kind of pipe sleeve. If so, what should be the material of the sleeve if the pipe entering is...

I have to embed around 15 meters of chilled water supply and return lines. I will give them min two coates to epoxy paint, insulate them with rigid fiber glass pipe insulation having vapor barrier...

My concern was, that DS put inside should not get effected with the moist environment inside. So no issues I suppose, one should go for weather proof ones I guess. Thanks anyway.

I am in the process of *designing a cold storage room, where should I provide the disconnect switch for the evaporating coolers (2 nos) and lighting fixtures. Should it be inside the cold storage...

Must say this thread has been a source of great info for me and gave me a chance to revise psychrometrics. Just little curious to know about adding humidifiers on the supply air way, if someone could...

Thanks a lot thermojohn and beenthere for explaining it so nicely. I am pretty clear now. Little extension to the same subject.....I have also been designing stream humidifiers / humidistats in the...

@beenthere,
Still 80% sounds too high. Don't you think if air with that % age of moist content will enter through diffuser inside the room, would make most of the diffusers look like sweating with...

Is it true that the moisture content of the air when it enters the conditioned room via supply air diffuser would be around 90%. I have designed the room at 50% RH but am bit confused after one of my...
