|Out in the Cold?
If you have a heating system failure, there is a slight chance we are the wrong people to call, but only a slight chance. If the problem is in the heat exchanger, heating coil, or the fan unit, we can help. If the filters are plugged, we have replacements. We also have energy-saving ceiling fans.
|New High-Ratio Elements Replace Cartridges
Two of our suppliers have recently introduced polyester felt media elements to replace the old paper cartridges in pulse jet collectors. A 37 sq. ft. element by Industrial Filter Industries uses 20-ounce singed polyester felt with reported efficiencies of 99.9% on 1.0 micron particles and above. A 28-sq. ft. element by Gore-Tex uses teflon membrane on 12-oz. felt with reported efficiencies of 99.99% on .33 micron particles.

|The Un-Calculated Risk
We still see many customers "booting up" new operations without considering atmospheric contamination. Call us during the planning stages. We can make valuable suggestions that will keep your project free of dust and fumes — probably at less cost than a "retrofit" later. You can be sure your future plans and developments — be they successes or failures — will be held in confidence.
to Riddle in Vol.2, No2. Pulse Jet Pointers.
The riddle posed in the last issue was:
We've counted the
cats in Kildare.
Let n be the number of cats, which must be an integer. Let s2 be the square, hence n = 1/3s2 Let c3 be the cube, and we have 3/4n = c3 or n = 4/3c3: hence c3 must be an integer divisible by 3. By equation 1/3s2 =4/3c3 or s = 2c3/2 Now for what least c, an integer, is c3/2 an integer, and c3 divisible by 3? Trying c = 9, we have s = 54 and n = 972; and 3/4 x 972 = 729 = 93.
