Is it allowed to use flexible joints at all connecting the fan to the ducts in smoke extraction systems?
Usually those fans are rated for 300 °C and 2 hours (UL listed in the US)
My question is if they are allowed at all, even if the joints are rated the same.
Thank you

I have been searching in Carrier product data for design approach temperatures for HX water cooled chillers but cannot find anything.
Do they not publish this info? If you do not know the design approach temperature how do you figure out if your approach temp. is too high due to dirty...
I have lots of experience in HVAC, but this is my first refrigeration project.
I working on a refrigeration installation of 700 tons, direct expansion (R22). This installation is 20 years old, the compressors (Sabroe reciprocating) are making problems and there is a lot of refrigerant leaking...
I have Trane 2000 tons centrifugal duplex chillers, and I am having problems getting them to reach full capacity.
I am resetting the cooling towers temperature. Could this be contributing to the capacity shortage?
I am short on 300 tons. The chillers were designed for 85F condense water, and...
The instrument piping is installed around cooling towers. It is copper and as you can see, it has a layer of green rust all over.
This installation is not older than 3 years.
What is the best way to protect this line? Paint? Wrap? Insulate?
Thanks
I work on a big and brand new chilled water plant of 20K tons.
It is a primary-secondary pumping system and the secondary pumps are controlled by differential pressure. They are 7 pumps, 150 kW each.
At the end of the secondary loop I have 2 booster pumps + 1 stand by, 30 kW each that take part...
