Convection Tube


Create the best aerodynamic effect in your greenhouse - all tubes are engineered for uniform distribution and proper mixing of air. A UV-resistane formulation with Ethyl Vinyl Acetate and Co-Polymer Resins provide added toughness and durability (4mm thick).

  • Each tube is custom-punched to match the selected BDP Modine Heating Units, Fan-Jet® or fresh air inlet with each specific house
  • Tube Hangers and Snap Rings have a unique design that allows for easy attachment to overhead wires, recommended spacing is 6'
  • Tubing will be punched at a 30° down-throw unless otherwise specified; typical punching is at the 4:00 and 8:00 o'clock positions
  • Specify "DEAD-CENTER" - 3:00 and 9:00 o'clock (under bench)
  • Specify "ON-EDGE" for one row of holes (under bench)
