KVCD Kele Damper Sneek Peek


At Kele, we pride ourselves on a commitment to meeting and exceeding customer demands in all areas of our operations. We have continued to listen to our customers and are proud to announce the coming of the Kele KVCD Commercial Control Damper Line. In addition to our current damper offering, Kele has partnered with a worldwide industry leader to manufacture a competitively priced OEM damper with the same high quality construction and performance that can be expected of all of Kele’s private label products.  These dampers will be manufactured with a patented frame design that uses no welds at the corners to ensure an extremely sturdy frame that is less prone to corrosion over time. The KVCD line will feature high quality rectangular (KVCD) and single (KVCDR) and multi (KVCDRM) blade round dampers available to you with standard 10 day shipping.

Kele dampers will feature Variable Symmetric Blade (VSB) design to increase damper performance. VSB design utilizes blades that are symmetric about their axis, and any combination of 4, 5, 6, and 7 in. blade widths to improve overall performance in several areas. First, symmetrical blades have identical operating characteristics regardless of airflow direction. This allows for increased mounting flexibility especially when space constraints exist, as the dampers can be mounted in either direction of flow. VSB design is also crucial in increasing free area around the damper. Because of the combination of blade sizes, we are able to reduce height or eliminate blade stops to maximize free area and improve damper performance. Finally, the symmetrical blades balance the airflow around the blade, reducing the torque that an actuator needs to operate the damper.   The VSB design on the Kele KVCD Dampers goes a long way in increasing damper performance and efficiency in installation and operation.

The high-quality and unique design of the KVCD dampers ultimately results in energy savings for you. By incorporating VSB design with high quality construction, KVCD Commercial Control Dampers limit leakage and pressure drop to provide one of the best performing dampers in the market. For example, Kele compared the pressure drop date of a KVCD-33 12” x 12” damper to a competitor’s 12”x 12” damper. Both dampers were installed in an identical system that draws 2000 ft/min of airflow. The results speak for themselves as the competitor’s damper measured in at a 24% higher (0.34 in wg) pressure drop than the KVCD damper (0.08 in. wg)!

We are proud to offer this line to our customers as an alternative to our current damper offering. The high-quality KVCD Commercial Control Dampers have all been tested in accordance with AMCA Class 1 or 1A and are available in many different sizes that are customizable to your needs. Ordering options include blade orientation options (horizontal or vertical), blade configuration options (parallel or opposed), flange mounting options, and free tagging available on each damper. Be on the lookout for more information about the Kele KVCD Commercial Control Damper line as we get closer to launch at the 2015 AHR Expo in January. Please stop by our booth (#3444) to check out the new line in addition to all of the other new and exciting things going on at Kele!

What is next, endicator?

In my last blog entry I raved about the endicator power monitor and how it will make my life easier and that is all true.  What the designers have done, unbeknownst to them, is they have made life easier for future DR too.  I’ll try to explain.

Chances are if you are reading this you are either a building automation professional or my Mom (love you Pumpkin) so I can be a little snarky with this part.  There is a commercial for a home security company that shows a home being blanketed in a warm blue blanket of 0s and 1s.  What could be more comforting than knowing your worldly possessions are protected by technology that is older than my father (no offense Pop)?  Don’t get me wrong, digital switches are a very effective and highly efficient way of detecting abnormalities and initiating alarms, but it is hardly innovative.

Innovation is used to advertise almost anything that exists.  I don’t know much about marketing but I’m sure that the wheel V2.0 was depicted on a cave drawing as being so advanced that if you were still using wheel V1.9 or less you were behind the times.  To get the benefits of wheel V2.0 you had to upgrade.  The axle was not available as an upgrade for older versions of the wheel.

This is where the endicator power meter shines and what makes it, in my humble opinion, the most exciting product Kele has ever introduced.  The endicator is ready for the next big thing you need to do with a power monitor.  The endicator can be ordered with or without communications cards.  Units can come from the factory with communication cards for BACnet, LON, Modbus, and N2 OR they can be added/changed in the field. Firmware updates can also be done in the field.   This means that as your customer’s needs change you can upgrade them – and it doesn’t stop there.  I don’t know what the next big thing will be.  It might be adding internet capability or (gasp) cellular.  Being able to upgrade in the future is truly innovative.

I guess to sum it up; the endicator design team has given me a gift with this product.  There is not much in life that is easier than being able to say “yes” to a customer and I’ll be able to say that a lot with the endicator.  This is where you come in.  Where do you see power monitoring going?  I’d like to know.

Making Your Job Easier (and Mine too)

My first exposure to power monitoring was the WT series. I started out in the warehouse shipping them. Then I progressed to stripping the wires used for the CT shorting assembly. After that I assembled them, put them in enclosures, and added the shorting switches when they were ordered. From the warehouse I moved to the sales department where I got to enter orders for WTs. Finally, I moved to tech support where I got to recommend, sell, and troubleshoot WTs. I am not ashamed to say that it was one of the most difficult challenges. Power monitoring, the WT in particular, made me cringe. High voltage/high current electricity is dangerous. While the WT was a fine product; it was very hard to troubleshoot – especially over the phone.

Then Kele had a significant breakthrough: The PT-9000 Series PowerTrak Monitoring Interface. Even the name is cool. It had 9000 in the series name long before Internet memes taught us that 9000 = cool. The PT-9000 went way beyond the WT. It was like adding indoor plumbing. The PT-9000 has 2 configurable 4-20 mA outputs and a pulse output for kWh. It also has lights, wonderful lights that tell the full story of how the unit wired – a gift to the telephone trouble shooter. To top it off it has an auto configure feature that corrected CT/phase wiring errors. Not long after the launch came the communication abilities (BACnet, LON, N2, Modbus) that made the user capable of capturing parameters never dreamed of by the WT.

And now we have the endicator™ Intelligent Power Monitor with its 58 monitored parameters, easy to use interface, installer focused design, standard NEMA 4X enclosure, I could go on for quite a while with this. I’ve only played with the beta but I’m pretty sure it can change Coke to Pepsi and find your car keys. It’s that cool. All kidding aside the endicator™ launch is very exciting for me. It truly is the evolution of power monitoring.

The WT series is still alive and working in many installations around the world and we still get the occasional tech call about them and they still scare me a little, but that doesn’t stop me from helping when I get those calls. Truth be told the WT did make me a better tech support person, kind of like the fat football coach that always made you run, called you horrible names, and yelled at you all the time. Sure you hated him, but he made you better.
