A Tale Of Two Engineering Projects

At our Boy Scout Troop meeting last night, we had adult volunteers in two rooms, putting their “day job” skills to use. Two of our troop parents are dental professionals, so they were working with the Scouts, as a group, to complete the requirements for their Dentistry Merit Badge. In the other room, a couple of other parents and I were making last-minute equipment preparations for the Troop’s annual Lenten Fish Fry.

Anyway, one of our projects this year is to fix or replace the fryer tank. Nobody knows how old it is or where it came from…one of our Assistant Scoutmasters has been around for almost 20 years, and it was here when he came. Now, it’s just a big metal box that sits on the stove and holds the oil that we fry the fish in, but with three engineers looking it over and coming up with ideas, it’s got the potential to be the most complex big metal box in the county. The current problem is only a ¼” crack near the top of a corner, but also on our “wish list” are items like:

*Handles: this tank is about 4 feet long, 3 feet wide, and 18 inches deep. It’s not heavy at all, but handles sure would make it easier to move around, wash, dry, etc.
*Drain: Currently, we use a small battery operated pump to empty about 10 gallons of oil out of it every Friday night. A strategically placed petcock valve will cut our clean up time to a fraction of what it currently is.
*Temperature control: these ideas ranged from a port for a permanently mounted thermometer to a thermocouple that we could tie in to a regulator in the gas line. We’re all scared of tapping into the gas line, so the thermometer is looking better and better. It’s always fun to see yourself on the news, but not when it’s because you were involved with a fire that burned a church building down.
*Material of construction: Stainless Steel is awesome, but we’re probably on more of an aluminum budget.

Last week, we had the pleasure of conducting an Efficiency Lab Test of a customer’s drilled pipe compressed air blowing device. It was doing the job, but it used a lot of air, it was loud, and it had been in place for as long as anyone could remember. As it turns out, our 12″ Aluminum Super Air Knife looks to be a viable solution to the items on their “wish list”: reduced air consumption, and lower noise levels…it’s going to cut both to a fraction of what they are currently. This is a significant improvement, because not only are they going to save $500-$1,000 per year on compressed air for each of two units, but the operators no longer have to wear hearing protection, since the maximum sound levels are going from 108 to 67 decibels…well below OSHA’s published 8-hour limit of 90 dBA.

These are two examples of what can happen when you get a couple of engineers involved in a project. If you’d like to find out how much you can save your wallet…and ears…by switching to EXAIR’s Intelligent Compressed Air Products, give me a call. If you find yourself hungry and on the east side of Cincinnati on a Friday night in the coming weeks, I can also tell you where to get a great meal in support of a great organization.
