Long Tube

Feeding tube of makeup air system

Canada Blower is an engineering company for air moving equipment. We developed a PT Tube replacement air supply system - one of the cheapest options for large industrial facilities are underground ventilation systems.

PT makeup air fan ventilation system is a new concept. Use some of the aerodynamic principles for the provision, tempering and the distribution of makeup air in a building in cold weather. It offers greater efficiency, economy and comfort makeup air units that most conventional.

When exhaust fans are used to provide ventilation, both for industrial and process exhaust and personnel comfort, a negative air pressure is created inside the building. This negative pressure causes several problems:

- Process exhaust systems are less efficient and may not function properly.
- Down flow can occur through gravity vents and result in the rear vent products of combustion tube and a lot of heaters and process equipment.
- Drafts are created that are a dsicomfort employees. Proper operation of exterior doors may even be affected.

Our feeding tube fan Makeup Air System solves all these economic problems, even in the coldest day of winter.

PT Fan the system consists of an air supply fan specially designed housing wall and a cushion of air powered post. A long polyethylene tube is attached to unit and extends horizontally into the building's support wire. It has precision drilled holes on both sides at intervals along its length and has a opposite end closed.

Each set of the fan housing is mounted on the exterior wall opening or connected to a ceiling fan air supply.

In the winter, conventional systems have makeup air to heat the cold outside air before introduction into the building. This is a costly process, both equipment and continuing energy cost. The feeding tube Fam Makeup Air System is a simpler system that uses heat waste3d construction and basic principles earodynamic for supplying, tempering and makeup air distribution. And that makes it less costly replacement air systems to purchase than conventional, install and operate.

When the makeup air is needed, the power input shutter opens, the fan becomes the source and supply of fresh air inflate the outer tube for its entire length. Discharge of air from the holes drilled in the tube located overhead, such as small high-speed jets, which creates a mixture troubled by the heat into the air. As a result, it is really warm outside air before it reaches the level of workers, the creation of a draft standard without performing air system.

PT usually several sets of fans are needed for a building, depending on the size of the building, the volume of makeup air required, the size of the PT models selected fan. additional heating, if necessary, can be supplied in a conventional water heater unit type space located tubes near the PT distribution.

PT Canada makeup air blower system has the following advantages over coventional up air units:

* Offers savings on initial investment and operating costs;
* Provides air distribution without drafts and uniform over tube instead of blowing air from a single source output;
* Uses less energy due to less power for the same volume of supply air and due to loss friction of blowing air through a heat transfer system is completely removed;
* It is easier and less expensive to install, as PT fan system is relatively light in weight ans polyethylene pipe can be installed in a fraction of the time normally required for conventional ventilation ducts;
* Remove coil problems typical UTA freezing heated hot water and steam heat exchangers;
* Recovers waste heat in most overload buildings - through the outside air mixing with hot air in the interior;
* Very quiet, usually within 20 fan Sones;
* Flexible capacity, which is achieved by implementing only the necessary number of units of PT on the basis of the temperature inside the building;
* Provides eworking a more comfortable environment to maintain the smooth flow of air and even temperature distribution.

Power Tube Fan Make-up air are Available in sizes 18-48 for air to flow up to 40,000 CFM.

PT Power Tube makeup air tube system is built with thick high-density tissue polyethylene fiber (8 x laminated with polyethylene coating with a thickness of 6 mils. It is 3.8 ounces per square foot yeard material. resistance rupture of 118 pounds per square inch. The material is fire resistant and comply with NFPA Standard 701. The tubes are available in two colors: blue and white. A polyethylene pipe end is factory dealed.

enough air to make-up should be provided for balancing exhaust ventilation general and ventilation process. Usually, several fans of the feeding tube is required, which is to distribute air throughout the plant. If additional hardening makeup air in specific plant areas is necessary, unit heaters can be added.
