  • Page 3 Introduction In August 2003 Brivis introduced the new 3 series Contour cooler and also a lesser featured contour was also introduced called the Brivis Profiler. The Brivis Profiler cooler was introduced to offer a budget model Contour to meet market demand.
  • Page 4 Brivis Advance The Brivis Advance was introduced in 2005 and is designed to take the place of the AD range of units up to Model AD56. However, the AD76 and AD86 will remain in production. In essence the Advance is a square shaped Contour/Profile, which sits upon the same base frame as the Contour/Profiler.
