Overview
Convection tubing has been proven as an easy and inexpensive means of distributing heat or circulating air. The tubing helps create a better, healthier air mix, eliminates stale air pockets, cold and dry spots, and reduces humidity. In winter months the tubing can be used to direct heat to the area where it is most needed. The heat is dispersed evenly for a more comfortable environment. In hot weather, tubing reduces the temperature by continuous distribution of fresh air.
For greenhouse use, it is recommended you use tubing with an ulta violet inhibitor. Ultra violet tubing should be used where the sun is most intense, or wherever a longer lasting tube is desired.
Convection tubing can be used for ventilation of poultry barns, stock farm buildings, mushroom farms and industrial applications.
Versatility
Poly duct tubing is generally available in either a 4 or 6 mil thickness.
Single Line Punching
This is the most widely used system for heating and ventilation. Tubing can be punched to specialized needs to suit all known fan systems. There are many available hole sizes. Hole positioning can also be customized to direct the air flow where it is most needed.
Multi-Vent Punching
Multi-vent hole patterns create greater turbulence that increases air flow. There are no more vent holes than single-line punching but they are positiont to permit greater velocity and turbulence of air mix. This type of punching results in a better air mix by distributing the air in several directions at one time. Results are a more exact temperature, humidity control and better growth.
Installation
Installation of poly tubing is relatively simple. It is recommended that you use sus-hoops for quick and easy hanging of poly duct tubing to an overhead wire. Sus-hoops are made of an extremely strong, tear resistant woven reinforced polyethylene. These hangars do not penetrate the plastic. They often outlast the tubing and are reusable. When installing these hangars, the first should be at least 10 feet away. Each sus-hoop thereafter should be placed not closer than 8 feet apart. The sus-hoop is merely brought around the tubing and fastened to the wire above with a sus-strap.
