SureFlow® Systems

VEF SureFlow® Hi-Performance Vertical Cased Series

The key component of a SureFlow® system is a custom designed fan coil with an integrated low watt circulator, which delivers the water flow through the coil and back to a primary loop. This allows the individual fan coils to be hydraulically isolated from one another and be decoupled from the distribution primary loop. This satisfies the comfort requirements of a cooling-only system with one pipe instead of two and for a cooling and heating system with two pipes instead of four, greatly reducing the horsepower demand for increased energy savings.


  • 600-2000 CFM
  • For floor mounted, vertical, ducted applications
  • Units have a removable front-access panel for complete access to coil and motor-blower sections
  • Provided with galvanized finish


  • Fast and easy system design — SureFlow® design software simplifies and automates the selection and rating of equipment in your project
  • Saves money — SureFlow® systems provide 4-pipe performance with 2 installed pipes or 2-pipe performance with 1 installed pipe, which reduces piping and labor cost by up to 40 percent
  • Fewer moving parts — zone controls, as well as water balancing valves and test ports are eliminated, thereby reducing the owner’s cost of maintenance
