Kele Customers Tell Us Why They Buy From Us!
It’s hard to be humble. While the Las Vegas AHR show is behind us, hearing what you had to say about Kele lives on! Several of our customers told us specifically what you thought about Kele. A short video below demonstrates a few of the highlights. When we asked the question “Why do you buy […]
Read PostAre You Sure You’ve Checked Everything?
Late one afternoon not long ago, a fellow got me on the phone for tech support. He said he had ten carbon dioxide transmitters on one DCP-1.5-W power supply, and they weren’t operating, and he had pulled out most of his hair. Each transmitter needs less than 100 mA to operate, so the 1.5A power […]
Read PostA Valued Customer’s Kele Story
We sold a variety of equipment on a job here in St. Louis County, consisting of fans, fire dampers, fire/smoke dampers, and grills. The fire/smoke dampers were to have factory-mounted actuators with end switches. But the salesman, when releasing the order for production, somehow deleted the end switches. After the arrival of the equipment on […]
Read PostWhen Electricity Acts Up
This past weekend, we were just back from a trip to market, and my wife was busy stowing the fruits, veggies, oils, kimchi, and spices. I was doing my usual chore of qualifying and sorting the plastic shopping bags as to fitness for cat litter duty, kitchen waste duty, and “other,” based on leakage potential. […]

That’s a common question. If there was a good, all-purpose answer to it, we’d make sure it was in every data sheet and on every Web page. Unfortunately, physical area isn’t the limiting factor in all cases. The gases that mix well with air (CO, CO2) can sometimes be treated by area because they fill […]
Read PostHow Much Propane is Left in My Grill Tank, Anyway?
Yes, we get questions from all directions at Kele tech support. This one started out as a level measurement problem, but it quickly turned residential in nature. Here’s how the Kele Engineering team handles it: Somewhere on your propane tank is stamped the empty, or tare, weight. It’s usually on the protective collar around the […]
Read PostActuator Sizing for Damper Applications
You have selected your damper by size and functional requirements, but now the question, “How much actuator do I need to obtain maximum close-off and to withstand the many cycles of operation?” This is a good question, and yet little information is published on this subject. Hopefully the following guidelines will aid you in your […]
Read PostNot To Be Used As A Life Safety Device
Reprinted from Spring 2003 Insights Not to be used as a life safety device – This phrase appears on a number of Kele catalog pages as a warning to customers that the particular product (usually a gas detector) is not to be relied upon to safeguard humans or animals from a particular hazard. It may, though, […]
Read PostHazardous Atmospheres: Intrinsic Safety
Reprinted from Summer 1999 Insights In the last edition of 20/20 Insights we covered the use of explosion proof construction to prevent a source of ignition from coming in contact with a room full of fuel and air. Strong enclosures with threaded or flanged covers can confine explosive forces within themselves and cool the escaping gases enough […]
