Power Tube Type Pt Make-up Air System

Canada Blower is a developer of various types of air moving systems. It developed a PT Power Tube Make-Up Air System – one of the most economical options for larger industrial plants ventilation air make up systems.

PT Air Make-Up fan system is a new ventilation concept. It utilizes some aerodynamic principles for supplying, tempering and distributing make-up air in a building in cold weather. It offers more efficiency, economy and comfort than most conventional make-up air units.

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

– Process exhaust systems are less efficient and may not work properly.
– Down flow can occur through gravity vents and result in the back venting of products of combustion from flues and stacks of heaters and process equipment.
– Drafts are created that are a dsicomfort to employees. Safe operating of outside doors may even be impaired.

Our Power Tube Fan Make-Up Air System solves all of these problems economically, even on the coldest winter day.

PT Fan System consists of a specially designed air supply fan, a wall housing and a motorized air inlet damper. A long polyethylene tubing is attached to the unit and extends horizontally inside building supported from wire. It has precision holes punched on both sides at specific intervals along its length and has an opposed end closed off.

Each fan housing assembly is mounted in the outside wall opening or connected to a roof air supply fan.

In the winter, conventional make-up air systems have to heat the cold outside air prior to introduction into the building. This is an expensive process in both equipment and continuing energy cost. The Power Tube Fam Make-Up Air System is a simplier system that utilizes waste3d building heat and basic earodynamic principles for supplying, tempering and distributing make-up air. And that makes it less expensive than conventional make-up air systems to purchase, to install and to operate.

When make-up air is needed, the motorized inlet shutter opens, the supply fan turns on and supplied fresh outside air inflating the tube for its full length. The air discharges from the punched holes in the tube located overhead as small high velocity jets which create turbulent mixing with the warmer inside air. As a result the outside air is effectively tempered before it reaches the worker level, creating a uniform draft free make up air system.

Normally several PT Fan systems are required for a building, depending on the size of the building, volume of make-up air required, size of PT Fan models selected. Additional heating, if required, may be furnished from conventional type space unit heaters positioned near the distributing PT tubes.

Canada Blower PT Air Make-Up System has the following advantages over coventional make-up air units:

* Offers savings in initial investment and operating costs;
* Provides draft-free and uniform air distribution from along tube rather than blasting air from a single source outlet;
* Uses less energy due to lower horsepower for the same supplied air volume and because of friction loss of blowing air through a heat transfer system is completely eliminated;
* Easier and less costly to install, as PT Fan system is relatively light in weight ans the polyethylene tubing can be installed in a fraction of time normally required for conventional ventilation ducts;
* Eliminates coil freeze-up problems typical for AHU with heating hot water and steam heat exchangers;
* Reclaims overhead heat wasted in most buildings – through mixing of outside air with inside hot air;
* Very quiet, normally within 20 Fan Sones;
* Flexible in capacity, which is achieved by running only the required number of PT units based on the temperature inside the building;
* Provides a more comfortable eworking environment by maintaining gentle air flow and uniform temperature distribution.

Power Tube Make-Up Air Fans are available in Sizes 18 to 48 for for air flows up to 40,000 CFM.

PT Power Tube Make-Up Air System tube is constructed of thick woven high density polyethylene fiber(8 x 8) laminated with poly coating to a thickness of 6 Mils. It is 3.8 oz. per square yeard material. Burst strength is 118 Lbs per square inch. The material is flame retardant and complied with NFPA Standard 701. Tubes are available in two colors: blue and white. One end of the polyethylen tube is factory dealed.

Sufficient make-up air should be provided to balance exhaust from general ventilation and process ventilation. Usually several Power Tube Fans will be required, located to distribute air throughout the plant. If additional tempering of make-up air in specific plant areas becomes necessary, unit heaters can be added.

Improve Your Selling By Thinking Ahead

For most salespeople, selling is all about getting customers to walk out with a product. If the customer buys one item, it is a successful sale. For advanced salespeople, just getting the customer to walk out with one item is not enough. Instead, a customer buying one item is only a sign that there is more than one sale to be made.

To make an additional sale, some forethought is required. You need to think about what your customer is buying and what they are going to use it for. For example, if a unshaven man comes in to buy a razor, you can assume that he is wanting to shave.

Making a second sale is easy once you have an idea of what the people is wanting to do. What could an unshaven man buying a razor also be sold? Think shaving cream. We know that the man will want to shave straight away, so checking that he has shaving cream might result in an additional sale.

A similar idea can be used to sell more of the same product. If you recognise that a regular customer is buying shaving cream for the 4th time we can assume that they are going to want more later. This action of thinking ahead means that we can now sell the customer a larger container of shaving cream. If there are no larger containers, we can always reduce the price for the customer if they by more.

Thinking ahead can also be used to compete with your competition. If you know that a customer is going to check the price of the competitors product, you can save them time and also make a sale. First you need to check out the prices of the competitors products in the morning. Later on when a customer is looking to buy one of your products, you can say what the competitors price is and then offer a price that is lower.
