Our History

• Melink Corporation was founded by Steve Melink
  in 1987.

• The company's roots began in testing and
  balancing services when Chili's signed on as
  one of its first clients in 1988.

• Melink pioneered an intelligent hood control
  system in 1991 in an effort to make
  commercial kitchen ventilation systems more
  energy efficient.

• The Intelli-Hood Controls can now be seen in
  restaurants, supermarkets, hospitals,
  schools, nursing homes, country clubs,
  hotels and military bases around the world.
