Happy New Year! We hope you are having a great start to 2020!  Speaking of new starts, I recently ran into one of the first HVAC industry customers that I called on as a new salesperson, fresh out of college.  We talked about those first projects we worked on together, and I was reminded of how much I learned from those experiences.  I also remember the sinking feeling I experienced as I realized that while I was gaining experience each day, that new-found knowledge also opened my eyes to the seemingly increasing list of what I still had to learn.  

Over the past three years, our knowledge of both grease duct systems, and that market as a whole, has grown exponentially!  During that time, we have also come to realize that there were things that we simply weren't able to learn until we gained more experience. Over the past year, this added knowledge has helped us develop new strategies for designing and pricing grease duct projects that should drastically help us compete in today’s market.  Whether we are competing with another manufacturer or simply the history of field welding, our recently updated strategies will allow us to design and price the right system for the application at the right cost. 

We look forward to seeing many of you at AHR, booth 3331, in Orlando next month where we can share with you many of these new changes to our grease duct strategy, and will help us all win more in 2020!

Grease Duct Does NOT Equal Zero Clearance
Recent research shows that the amount of zero clearance sold in a given market ranged between 5-30%. If your RFQs are outside that range you may be overdesigning.  There are exceptions; For example, if your AHJ requests UL 2221 compliance, then you quote our Zero Clearance product. However, the purpose of UL 2221 is to achieve a 2-hour fire rating.  Many applications don’t require this rating or the associated zero clearance.  Due to a lack of information or the desire to avoid mistakes, the number of quotes requesting zero clearance are far higher than the actual need or the actual number that are sold with zero clearance. The result of overdesigning and quoting zero clearance is often overpricing.  The jobs you could win - you won’t. If you do win the job, you could needlessly leave margin on the table. DuraVent is the Answer! Using DuraVent’s broad product line positions you to win.  We have 3 double wall product lines that are not zero clearance and 1 single wall line.  Appropriate use of all 5 product lines and bidding the right clearance is the answer. You can also mix and match product lines to align with the varying clearances that are seen in almost all duct routing.

The draft system consists of a single blade damper, a butterfly type damper-actuator, and is combined with a single appliance CDS controller to maintain constant negative or positive pressure in the connector.
