MCDLG is Here to Help

The Mestek Commercial Damper and Louver Group is here to help!

The title says it all. The Mestek Commercial Damper and Louver Group (MCDLG) is here to help! We provide support for each stage of the purchasing process: from continuing education to meeting project requirements. You can count on us!

From continuing education, to project considerations, all the way to the finished product, and to post-sales support. Let us take a moment and go over some of these options.

For education

MCDLG offers free self-paced courses online through AEC Daily. Our three courses cover the basics of louvers, control dampers, and UL life safety dampers. Each course offers credit towards continuing education requirements. Learn the basics with MCDLG.

Learn the basics of control dampers with our course, An Introduction to Air Control Dampers. This course covers everything you need to know: damper types, what they do in your HVAC system, the function of various component parts, and how to choose the right damper for your application. We also cover the important ratings to consider when choosing control dampers, such as the damper's pressure drop and its air leakage rating.

Life safety dampers are a vital component for your HVAC system. Our UL damper course, Fire & Smoke Protection with Life Safety Dampers, goes over the basic stats, terms, and principles involved in choosing UL-rated dampers for your passive fire protection system. We also cover the tests involved in approving a life safety damper for use in passive fire protection, as well as the various installation types approved by UL. Get a comprehensive guide to UL life safety dampers and receive continuing education credit!

In Louvers for Style and Aesthetic, we discuss how louvers can turn dull facades into works of art. Louvers can be more than ventilation covers, although they play an important role in that respect. Learn the basics of louver construction and the various terms used to describe a louver's performance, like pressure drop and water penetration. We also discuss the aesthetic properties of louvers and how they can enhance a project's overall style. Complete the course at your own pace online and earn learning units from AIA.

Would you rather take a traditional approach to learning? Consider scheduling a webinar with an industry expert from MCDLG. All of our courses provide continuing education credits for a variety of institutions, including ASHRAE's PDUs and AIA's LUs. Learn the basics of UL dampers and earn credit, at your own pace.
