The New York City Transit Authority and Houston Metropolitan Transit Authority recently announced that they have included the Haldex Consep Valve into their new bus builds starting in May. The New York City Transit Authority will be purchasing 850 buses from Daimler Chrysler Bus North America, and the Houston Metropolitan Transit Authority will be purchasing 50 buses from Daimler Chrysler Bus North America.
Haldex says its Consep condenser/separator is a low-maintenance, effective and simple way of pretreating hot, moist air before it reaches an air dryer, and is useful where there is high air demand or severe duty cycles such as in transit and vocational applications. The Consep also is effective on any vehicle with problematic compressors that pass excessive amounts of oil, according to the Kansas City, Mo.-based company.
Within the vehicle’s air brake system, the Haldex Consep is designed to condense, separate and remove 90 percent of damaging oils, liquids and other contaminants from the airstream. According to the company, the Consep merely spins the air in a fixed cyclone and separates the contaminants, which then are expelled from a heated purge valve.
When installed properly, the Consep reduces corrosion and possible failure of air brake system components caused by contamination, and significantly increases the air dryer desiccant life, Haldex says.
