Keeping the Rainforest Tropical

When one method posed problems, mechanical engineers turned to an alternate technology to make patrons and animals comfortable at the zoo.

A rainforest may not leap to mind when one thinks of Cleveland, but the fact that one can associate the two words is largely due to mechanical engineering and the flexibility the discipline often contains.

Without state-of-the-art HVAC technology, it's doubtful that this unique tropical habitat—located within the Cleveland Metroparks Zoo complex—could exist, and it continues to benefit from equipment improvements, such as advanced motor and drive design. Read entire article...

Energy Savings at Dolphin Cove

One of the most popular attractions at SeaWorld Cleveland in Ohio is Dolphin Cove. SeaWorld animal care staffers teach their guests about dolphin anatomy and behavior, and show them how to give the signals used to put the graceful aquatic creatures through their performances.

Besides instructing its patrons about dolphin physiognomy and eating habits, SeaWorld could teach them about energy savings. It replaced the throttling valves of Dolphin Cove filtration pumps with adjustable speed drives, or ASDs. Read entire article...
