propane autogas, and the Propane Education & Research Council (PERC) conducted a seminar on how retailers can increase their summer load by educating lawn care compa- nies on the benefits of propane using propane in their mowers. Clark Peters, vice president of manu-
facturer's representative E.W. Leonard, led a seminar on propane-fired absorption chillers and chiller-heaters from Robur that offer both heating and cooling. He highlighted several advantages of the equipment, such as its high efficiency and standard components that are easily rec- ognizable and repairable. According to Peters, the units can boast
efficiencies to 140 percent, utilizing 100 percent from the propane, 50 percent from natural sources such as the ground, water or air, and accounting for 10 percent flue loss. "When we're making heat, we can
take that extra heat produced and use it," he said. Another advantage to the systems is
their flexibility and modularity, allowing them to be integrated with existing boil- ers or solar systems in order to maximize their seasonal performance or expand total heating capacity. "The chillers have a 25- to 30-year life-
cycle with just minor repairs," Peters said. "And the inside contains familiar com- ponents like a gas burner and Honeywell gas valve." Among the many exhibitors introduc-
ing or demonstrating new equipment was Bergquist, which recently announced they will be distributing propane equipment from the Cavagna Group, including the line of Kosan+ residential regulators and internal valves for bulk storage. With the newly developed Kosan+
line, Bergquist and Cavagna, an Italian company with more than 40 years of expe- rience, have worked together to design a regulator specifically to meet the needs of the U.S. propane market. Bergquist also featured newly devel-
oped internal valves, relief valves and commercial/industrial regulators from Marshall Excelsior Company (MEC).
