Developed by the Queens-based Metro Group, founded in 1925, this propriety delivery system uses environmentally sound "solid-board technology" (see above) mounted directly on your tower to deliver the cleaning agents, biocides and all those other goodies that keep us from getting the likes of Legionnaires' disease. The automatic delivery of concentrated solids eliminates the need to keep 55-gallon drums of chemicals around, and, the company says, helps minimize both your storage needs and your staff's exposure to chemicals and back injury.

Metro also claims its system reduces operating costs and brings energy savings due to "more efficient chemical application/delivery [and] available battery-operated chemical actuation and system conductivity control — all of which translates to enhanced heat transfer by reduced corrosion, deposition and microbiological fouling."

Given its nearly 85 years in the business, we'd be inclined to give Metro the benefit of the doubt. Because barrels of caustic chemicals does not sound more fun than a barrel of monkeys. Hmm ... barrel of monkeys. Never understood that term. A barrell of puppies, now that sounds fun. But whoever came up with the line about monkeys, well ... there must have been something in the water.
