Wickerbill airfoils on low-speed ceiling fans allow a smaller size to move as much air as fans 40% larger. The fans are ideal for situations where larger fans won't fit due to space constraints imposed by equipment such as conveyors and cranes. The patented fan employs 10 airfoils to move a massive column of air at a relatively slow speed. HVLS Fan Co.; hvls.com TO VOTE, WRITE 90 ON BALLOT For more information, write 90 on card

Modu-Fire combines full-modulation burner control with a time-tested, modular, hot-water boiler design. The result is modular full-modulation. It operates across a 5:1 turndown ratio; not step fired but infinitely adjustable from 20-100% of rating, resulting in the ultimate in non-condensing efficiency, up to 88%. The unit reaches peak efficiency at part-load, exactly where boilers operate most of the time. Patterson-Kelley; pkboilers.com TO VOTE, WRITE 26 ON BALLOT For more information, write 26 on card

Flo-Direct has a top-mounted gas burner that fires downward through a centrally located flame tube. The flame heats the falling water, which contacts a bed of packing rings where heat transfer occurs. An exchanger wall, minimizing scale, does not separate hot gases and water. Water at 130 to 185 F is available within 15 to 20 sec. of demand. Armstrong International, Inc.; armstrong-intl.com TO VOTE, WRITE 69 ON BALLOT For more information, write 69 on card

Blue Max Plus is a handy fluorescent leak detector that conveniently clips onto a shirt pocket. It features an adjustable service mirror and a unique telescopic extender that provides a reach of 28-in. This makes it much easier to pinpoint leaks in hard-to-reach parts of AC&R units that are off-limits to larger lamps. The solid-state LED bulb has a life of 100,000 hours.

Fresh Air filters have a 30-35% MERV 8 prefilter layer followed by a layer of activated carbon media. The carbon media is sealed in a sleeve of spun-bonded synthetic scrim to prevent carbon dusting. A MERV 8 efficiency rating means the filter achieves a minimum of 70-85% efficiency on 3-10 micron particles as determined by ASHRAE 52.2 Test Method.
