Kitchen Exhaust Ventilator

Cooking equipment that produces smoke or greaseladen vapors shall be equipped with an exhaust system that complies with all the equipment and performance requirements of this standard. All such equipment and performance also needs to be maintained per the requirements of this standard during all periods of operation. Specifically, the cooking equipment, hoods, ducts, fans, fire suppression systems and special grease collection or energy control equipment are to be kept in good working condition.

Airflows throughout all components of the system must be maintained at intervals necessary to keep the operating conditions of the equipment at the proper levels. All interior surfaces of the exhaust system shall be reasonably accessible for cleaning and inspection purposes. Except where enclosures are required, hoods, grease removal devices, exhaust fans, and ducts shall have a clearance of at least 18 inches to combustible material, 3 inches to limited combustible material and 0 inches to non-combustible material. (See Fig. 1a – 1e.) This is only a guideline and there are several exceptions to these.

Ultimately, the authority having jurisdiction (AHJ) has the final say in the acceptance or rejection of the installation. In the event of a fire within the exhaust system, the system must be inspected by qualified personnel and approved by the AHJ to determine whether the system is structurally sound, capable of maintaining their fire protection function, and suitable for continued operation. Clearances can be reduced by the installation of field applied or factory built grease duct enclosures. These must demonstrate that they provide sufficient mechanical and structural integrity, resiliency and stability when subjected to expected building environmental conditions, duct movement under general operating, and fire conditions. A drawing of the exhaust system installation along with a copy of operating instructions for subassemblies and components used in the exhaust system, including electrical schematics, shall be available on the premises.

Upblast fans with the motors surrounded by the airstream shall be hinged, supplied with a flexible weatherproof electrical cable and a hold open retainer for servicing and cleaning, and be listed for this use. Inline fans shall have the motor located outside of the airstream and have the belts and pulleys protected from the airstream by a greasetight housing. The fan must be securely bolted to the flanges of the exhaust duct using stainless steel bolts, nuts, lock washers and gasketing rated for 1500 deg F. Flexible connectors are not be used. If the design or positioning of the fan allows grease to be trapped, a grease drain directed to an accessible grease receptacle, not exceeding 1 gal, must be supplied.

How To Increase Blowers Performance

Industrial processes and plant ventilation systems often need more air than originally designed. Increased production requirements, process changes, and facility renovations are a few of the major reasons. Additionally, the lack of adequate maintenance over time can negatively impact system airflows. This article discusses several procedures that can increase airflow. Often airflow can be increased by adhering to proper fan maintenance procedures as outlined in fan installation and maintenance literature.

Fan speed can decrease by as much as 10% to 20% when belts are too loose, with a corresponding loss of airflow. A fan cannot perform as designed if the air flow surfaces are distorted by contaminants. Even in large fans, a sixteenth of an inch of build up can reduce performance. Centrifugal fans will move some air even when running backwards. While some types would use so much horsepower they would trip circuit breakers, other design s could run for years without being detected. Fan components may be out of position due to routine cleaning or painting or the wheel could have shifted during shipment. For backward inclined fans, the relation of wheel to inlet cone is very critical. Even a quarter of an inch can have a major impact. The fan’s installation and maintenance literature shows the proper positioning of the wheel to the inlet cone.

One of the easiest solutions to low airflow problems is speeding up the fan. While airflow is increased by speeding up the fan, so too are static pressure, noise, and power requirements. Therefore, while increasing the fan’s speed is an easy procedure with low first cost, the additional operating expense over time makes it the most costly solution. When increasing fan speed, it is necessary to check the maximum safe speed of the fan and make sure the motor is capable of the horsepower required to run the fan at the new speed. But never run a fan beyond its maximum safe speed.

On a first-cost basis, adding or replacing fan equipment is the most costly alternative. However, on a life-cycle-cost basis, considering operating and maintenance expense, it can be the least expensive, as compared to increasing the speed of an existing fan. Sometimes a second fan may be added, either in series or parallel with the original, although it may be more cost effective to simply upgrade the system with a new fan capable of the required airflow and pressure. Adding another fan in series will increase the airflow because of the additional pressure. The operating point of the new system moves further out/up the system curve. Where duct size is adequate to handle the desired amount of air but the existing fan doesn’t provide sufficient pressure, a second fan in series may be the best solution. However, make sure the ductwork can handle the increase in pressure. Adding another fan in parallel with the first will increase airflow due to the combined capacities. Because capacities are being combined instead of pressures, a greater increase in airflow will result for a given system. However, system pressures will also increase and caution is required to avoid the unstable operating area of the combined fan system.

Advantages Of Franchising And Distribution

The rapid expansion of the market economy has largely been made possible due to the advent of globalization. Today the idea of business is no more confined within the geographical boundaries, instead it has become global. In order to survive in the competitive market it is important for each and every business unit to take its products and services right to millions of potential consumers. But it is not always possible for any single entity to do that. This is why franchisee or distributorship has emerged as an important part of modern economy. Distributors, though not directly related to company, are entrusted with the task of selling the products of a specific brand to retailers in a certain region. There are certain advantages of distribution and franchising if the company can choose the right and most competent distributor or franchisee.

Direct to the consumer

The main advantage of distribution or franchising is that companies can easily take their products directly to the consumers. This gives a boost to the business as a whole and allows companies gain a global exposure all at once. It is needless to mention that in order to survive in the competitive market it is important for each and every business unit to grab the attention of the consumers on the very first go. A distributorship business helps entrepreneurs do exactly that.

Increase market share

Another important advantage of distribution and franchising is that companies can increase their market share to a large extent. With the help of distributors companies can create a demand for their product in the market, thus outrunning their competitors in the market. Though it is true that market saturation leads to diminishing demand, companies can find more and more new markets with the help of distributors. Thus, companies can largely enhance their presence in the market by selling their products through distributors.

Increasing profits

Selling products through distributors can also help companies increase their profit level to a large extent. It is not possible for a business enterprise to open its own outlet in each and every city, town and village in the world and so selling the products through distributors can be the most effective and reliable way of increasing profit margin. The steady expansion of the global economy has made it absolutely necessary for each and every business organization to make the best possible use of its resources.
