Vertical commercial dryer vent from Todd Case
« on: October 28, 2009, 08:13:51 AM »

This question was emailed to me and I thought it was worthy of posting here.  It is from Todd Case.

Rick,
I have taken care of the exhaust venting, and other HVAC needs at a local trucking terminal. They now wish to use one contractor to do almost all of the work around the terminal facility. They have asked me to propose a revamping of their current dryer venting system.

Here is what I know about commercial dryer venting. Uh...........

That said, where do I start with the design and proper installation of a commercial dry venting system?  Should I point them in the direction of a commercial dryer venting company? Does this niche even exist?

This is what they currently have in place.
Two electric clothes dryers.
Each dryer is connected via 4" flex to separate 4" rigid duct ran vertically and concealed in a wall cavity or approximately 8'. The vent then comes out of the wall and is connected to b-vent which exits the building and is terminated with a b-vent style cap.

The current problem with this system is the caps and rigid duct fill with lint and restrict the flow of hot exhaust air. In turn the drivers disconnect the dryer vent from the back of the dryer and wreck the air quality in and around the laundry room.

I would like to redesign the system to bring it up to code and make it as easy to service as possible. Any suggestions?

I'd start with the ICC mech code for dryer venting. 
link:
2003 http://www.dryerbox.com/convertions/pdf ... l-Code.pdf
2009 http://www.dryerbox.com/convertions/pdf ... t_Duct.pdf Sounds like the units they use are regular dryers with 4" exhaust ports. 

Look for super efficient vents (terminations), see this chart:

Use the semi rigid aluminum flex for the transition hose, not the wire bound flex.

Clean the existing pipe real well, use long turn ells where you can.

Good luck.
