Fan Blower Performance Curve
By: oleg tchetchel
Fan curves are based on laboratory test data and are sometimes referred to as "test curves". A typical test curve will often define the performance parameters for a specific design and size of fan, operating at a given speed, moving a gas of a given density. Inspection of this graph will show that it is actually composed of four separate curves.(read

Fans Vibrations
By: oleg tchetchel
There is a trend in the fan industry that is causing significant changes in fan design and in the manner in which fans are marketed. As a result of the maturing vibration measuring instrumentation market, computer software and maintenance training programs have been adapted which equate “low vibration” with long life, igher quality, and lower maintenance costs. The fan manufacturers used to be the “vibration experts” and set the tolerance for acceptable levels of vibration.(read

Industrial Gas Scrubber
By: oleg tchetchel
Gas scrubbers are applied where removal of fine particulate from corrosive, hazardous or volatile gas streams is required. Venturi scrubbers wash dust and particles out of the air by forcing the air into a spray chamber, where fine water particles cause the dust to drop from the air stream. Where applied, venturi scrubber technology is able to achieve the highest particulate collection efficiency of any wet scrubbing system.(read

High Temperature Exhaust Ventilator Fan
By: oleg tchetchel
The main purpose of the NFPA can be summarized into three main categories. First, NFPA promotes the science and improves the methods of fire protection and prevention, electrical safety, and other related safety goals. Secondly, it obtains and circulates information on these subjects. And thirdly, it secures the cooperation of its members and the public in establishing proper safeguards against loss of life and property. The fourth organization is Underwriters Laboratories, Inc.. UL is a non-profit, independent organization that maintains and operates laboratories for examination and testing of devices, systems and materials to determine their relation to life, casualty hazards and crime prevention. UL has three safety standards that apply to emergency smoke exhaust products. UL705 is concerned with the mechanical and electrical construction to insure safe operation. All electrical components (motor, wiring, switches, enclosures, etc.) must be ULlisted. UL793 is concerned with the lifting mechanism for the butterfly dampers and the fusible link. In order for a product to be listed in the UL Directory under ÒPower Ventilators for Smoke Control Systems,Ó it must meet the requirements of both UL705 and UL793. Additionally, UL must witness a full-scale test of a fan operating for the required time at the specified elevated and temperature.(read

Process Fans For Industry
By: oleg tchetchel
To reduce greenhouse gases and produce a useful byproduct, many countries, states, counties, and cities are replacing landfills with industrial composting systems. One of the most common methods for large scale operations is Aerated Static Pile or Active Aeration composting. ASP refers to any of a number of systems used to biodegrade organic material without physical manipulation during primary composting. Our fans play a key role in these systems by forcing air through an array of perforated piping placed in and around the compost material to provide air circulation for controlled aeration. This allows system operators to maintain the desired temperature, moisture, and oxygen levels within the piles during decomposition.(read

Industrial Process Ventilation Blower Fan
By: oleg tchetchel
As the industrial application specialists, Tenderall Fan has the expertise needed to supply the proper air moving equipment that is specifically designed for resisting the corrosive nature of these compounds. In other pollution control systems, our fans are installed on the clean side, which offer a higher efficiency design for moving gases into a scrubber or other device. One of the major challenges in wastewater and sewage treatment plants is controlling the odors that are emitted. These plants are often located in residential areas and forced to adhere to strict codes and regulations. These odors are caused by gases such as hydrogen sulfide and ammonia. To reduce odor emissions a variety of systems have been found effective, such as thermal oxidation, chemical scrubbers and biofilters. The fan requirements in these processes are similar in that they require special alloys, coatings or fiberglass construction.(read

Make-up Fan Ventilators
By: oleg tchetchel
In the environments where the inside air quality is acceptable, often a portion of the inside air may be drawn back through the make-up air unit where it is recirculated back into the building. Advantages of using Hartzell Recirculating Make-Up Air units are lowered heating costs, better indoor air mixing (reduced air stratification), as well as constant building pressurization.(read
