Project: Baptist Hospital
Location: Lexington, Kentucky
Installed: 1990
Construction: 10" cast in place reinforced concrete, structural steel beams and columns. Bottom of bridge is not insulated.
Use: Helicopter (up to 34,000 pounds) landing pad and transport ramp.
Heating Circuits: 14,000 feet of Snow Tech™ 1/2" pipe, 3" below surface.
Heat Source: Low pressure steam.
Snow melt supply temperature: 130º F ~ Snow melt return temperature: 108º F
Snow melting rate maximum: 2 inches per hour

Features: In 1991, a severe ice storm forced the closure of all airports and highways in Kentucky. Because of the Snow Tech™ snow and ice melting system, this was the only operational heliport in the state. The Air National Guard used this heliport as their base of operations for almost a week, transporting severely injured patients to the hospital for treatment.

Project: Coal Silo - CRS
Location: Harrisburg, Pennsylvania
Installed: 1991
Construction: 40' diameter concrete silo, 20' thick concrete slab, 1/2" stainless steel cone.
Use: Coal silo - freeze protection - coal.
