Commercial Kitchen Ventillation

CKV or Commercial Kitchen Ventilation systems are specialized ventilation systems designed for use in commercial cooking applications. The CKV system begins at a hood suspended above the cooking appliances. The hood is designed to capture heat and cooking effluent or pollutants generated by the cooking process. Cooking appliances vary from fryers to grilles and live fuel barbecues. The hood is ducked into a vertical or horizontal duct referred to as a grease duct. The grease duct is a sealed duct leading from the hood to the building exterior. An air mover or fan creates a negative atmosphere at the hood. Fan air volume is selected based on the face area or length of the hood. Commercial kitchen ventilation systems are difficult to balance. One only has to walk into a restaurant to take notice of this fact. It is not normal for a restaurant patron to depart from a dining experience only to have their clothing saturated with grease and odors or the smell of smoke from the cooking process. Some may enjoy this, others may not notice. It is a common fact that indoor air is more polluted than outdoor air. Add to this, poorly balanced CKV systems and you have a recipe for poor air quality both indoors and out! A few constituents in commercial cooking are; grease vapors, carbon particulate, carbon monoxide, water vapor and chemicals produced during cooking. As recently as 2007, the State of California, Washington and Georgia have begun to regulate commercial cooking exhaust emissions. Some California counties issue permits to a certain “burger” chain restaurant limiting the chain to a maximum production rate in pounds per hour. Just because it smells good does not mean it is beneficial to your lungs! There are numerous companies and numerous technologies that have been applied to CKV operations in an attempt to control indoor and outdoor air pollution from commercial kitchen operations. Air Dynamics Industrial Systems Corporation has developed a number of unique, proven, cost effective solutions to this problem.

Downdraft Tables

A downdraft table is used to collect dust from a specific operation such as sanding, grinding, polishing and welding. This type of equipment is classified as a pollution control device. The tables can be self contained or connected to a centralized dust collection system. When a self contained downdraft table is energized, a motor and air mover rotate to produce air volume and create a negative atmosphere below the surface of the table. The table top is typically slotted to allow dust to be drawn into a chamber where the dust is captured using some form of filter media. The filter media can be arraigned as static filtration or dynamic filtration. In a static filter configuration, the filters are usually disposable. Obviously, this configuration is less expensive initially. A static filter configuration is usually a pleated panel type filter. Note that static filtration cannot be cleaned on-line. As time passes and the dust builds up on the filter surface, the air volume throughput is reduced proportionately. In a dynamic filter configuration the filters are usually cylindrical cartridge type that are coupled to a continuous duty pulse jet cleaning system. Some filter cleaning systems are operator initiated. This type of filter can last a year or more. Some filters are washable. A downdraft table comes configured in many sizes and performance ranges. The table must be selected based on the specific operation. A simple formula can be used to determine the downdraft velocity of the air. Velocity = CFM/Area (sq.Ft.) Example – 36” x 72” = 2592/144= 18 square feet. If the fan produces 2700 cfm at 4” wc of static pressure, the downdraft velocity is 150 feet per minute. Note the 4” of water column static pressure at the rated flow. The fans ability to overcome the resistance of the filter and associated dust cake is paramount to the performance of the table. Typically a squirrel cage fan wheel is not suited for static pressures above 2” wc. Caution must be excercised when using a table for metal work. Most dry filtration type downdraft tables are not suitable for combustible metal dusts. Please consult with our specialists to determine what type of system will be best suited for your application.

Industrial Scrubber

What is an industrial scrubber? An industrial scrubber is simply another word for an air cleaning device. Some manufacturers interchange this term with wet or dry airstream scrubbers. We have further classified our “wet scrubber” as our hydrodynamic scrubber. A wet scrubber is commonly used in the realm of air cleaning devices for specific pollutants. The wet scrubber is an adaptation of a portion of the natural air scrubbing process that occurs in our atmosphere. If this were not so, we would have saturated our volumetric air space long ago with deleterious results. The APCD wet scrubber is convenient to use when the process air stream is hot. An example application for the industrial scrubber incorporates a wet scrubber on the discharge of a hot process where pollutants are in vapor form. The pollutant may be a liquid applied to the process then sent to an industrial oven to cure the product. Upon curing, some of the liquid pollutant/s is converted to vapor through evaporation. The oven exhaust is vented to atmosphere where it has the potential to contribute to man-made air pollution. Nature is quite capable of removing these types of pollutants from the atmosphere through numerous naturally reoccurring atmospheric conditions. This of course is frowned upon today. To capture this pollutant before exhausting the process air to atmosphere, we re-create a similar scenario that converts the pollutant in vapor to a solid form. Once in a solid form, such as a droplet, we can then manage the pollutant via additional treatment such as filtration, etc. followed by proper and legal disposal practices. This is an important aspect to consider when treating pollutants with a wet industrial scrubber. i.e. one pollutant stream is converted into another pollutant stream from dry to wet. Designed properly , the wet scrubber is a viable method to control the output of pollutants to the atmosphere. The hydrodynamic scrubber may also be utilized to render hazardous combustible dust inert. An example would be the conversion of aluminum dust into an inert dust. Air Dynamics Industrial Systems Corporation can create a custom configured industrial scrubber for your specific application. Many times, we can reduce energy by up to 75% and reduce maintenance by 80% or more. Please call us to discuss your specific application. Our toll free number is 1-800-743-3201.

Lint Removal System

Commercial laundry systems are typically found in high occupancy, institutional facilities. Common problems associated with commercial laundry operations are fugitive laundry lint emissions polluting the exterior of the facility and fire hazards. Air Dynamics Industrial Systems has successfully designed and engineered a solution to these challenges. By law, commercial laundry facilities must also comply with state and local codes for particulate matter discharge from the facility. A facility with a large number of commercial dryers can discharge hundreds if not thousands of pounds of dust and lint into the atmosphere per year. Particulate matter of any type and size is regulated by local air quality departments of the environment and the US EPA. Many states have geographical areas referred to as US EPA non-attainment areas. These are areas where air pollution levels are above state or federally mandated levels. Why should a commercial laundry operation specify a high efficiency lint collector? The risk of fire increases proportionally as the lint collector efficiency decreases. This is due to the deposition of flammable laundry lint inside ducting and in the vicinity of dryer exhausts in and around commercial structures including rooftops. Properly designed, sized and installed, a high efficiency laundry lint remover or lint collector will minimize the risk of fire in commercial laundry operations in addition to being in compliance with national and local environmental laws. There are a number of lint removers on the market for commercial laundry operations. Cost is typically associated with lint collector efficiency. Low cost, low efficiency lint removers sometimes incorporate a cyclonic design combined with a nylon mesh internal sock or bag. High efficiency lint removers incorporate filtration that complies with Federal PM 2.5 and lower particulate standards.A commercial lint remover or lint collector will incorporate features that permit continuous duty use, easy emptying of contents, high dust and lint removal efficiency, low maintenance, fire protection, automated filter monitoring and cleaning systems and so on.To learn more about the subject, please contact our design center for details. Air Dynamics Industrial Systems Corporation can easily design a commercial laundry lint removal system to meet or exceed environmental laws as well as help keep your facility functioning at full capacity.

Oil Mist Eliminators

Modern CNC metal cutting utilize high speed machining, milling and turning equipment that is increasingly housed in a fully enclosed machining center. The need for effective, efficient and complete abatement of oil mist, coolant mist and smoke is critical to a safe workplace in the CNC shop environment. Why is it important to keep these pollutants out of the machine shop air we breathe? When CNC machining of metals is performed, a coolant or lubricant is applied to facilitate forming of the metal parts. The liquid oil or coolant is converted to particulate matter (PM) in the form of small droplets or aerosols and vapors due to friction and heat at the machining/part interface. These indoor air pollutants generated by metal working fluids, chemical additives and fluid microbial growths are hazardous to the human respiratory system. The United States department of occupational safety and hazard administration has published limits for exposure to these pollutants. For more information please see the OSHA website at https://www.osha.gov/SLTC/metalworkingfluids/ An independent article on the subject of Metalworking Fluid Mist Occupational Exposure Limits: A Discussion of Alternative Methods is available at http://www.jborak.com/publications/docs/Cohen-Metal-Working-Fluids.pdf An enclosed machining center does not mean the metalworking fluids and smoke will be contained in a safe manner. Proper engineering controls are necessary to abate such hazards in the work place. Oil mist collectors or oil mist eliminators for industrial machining centers come in numerous forms.Oil mist collectors utilize centrifugal separation technology, progressive filtration, and electrostatic technology. Over the last 22 years of evaluating these types of systems, we are satisfied that properly applied there is one technology that safely removes metal working fluids (MWF) and smoke from the air within and around machining centers.Using an aerosol particle counter, we can reliably provide air that is scrubbed of MWF condensables and smoke to a level of 0.0 mg per cubic meter.For more information on how to obtain clean air in a metalworking machine shop, please see our download “Is clean air really possible in a CNC machine shop?”There are several critical aspects to consider when investigating the effectiveness of an oil mist eliminator or oil mist collector purchase. How efficient is the oil mist removal system over time? The easiest way to determine this is by conducting a side-by-side test over a minimum of 60 to 90 days. This will be sufficient time in which to evaluate the various technologies, including energy consumption. After a specific period of evaluation, prior to replacement of any filters in the system, how does the unit perform when the outlet air is measured for aerosol and particulate matter using a particle counter? How much energy is consumed during the process? please call us to discuss your machine shop metal working oil mist collector application. Our toll free number is 1-800-743-3201.

Industrial air cleaning equipment varies widely in size and type. The United States industrial era precipitated the need for air cleaning equipment to protect the air integrity of both indoor and outdoor air quality.

Clean air is important for workers confined to production equipment or an indoor or outdoor confined space. The average person has a lung surface area of about 1600 square feet. This lung area is the pathway between the air we breathe and the oxygen we need for survival.

In a polluted environment, lung capacity is reduced causing problems for the longevity of the worker. One tragic lesson since the industrial revolution was the seemingly innocuous production and handling of asbestos products.

It is proven over and over that many man-made and natural products are hazardous to one’s health.

What exactly do pollutants do and why are they regulated?

Pollution from industrial manufacturing operations is produced in many forms. Pollutants are usually byproducts that emanate from the production of goods manufactured in one-man workshops to manufacturing production lines where tens of thousands of workers produce electronic consumer goods such as your cell phones. Pollution is not restricted to indoor operations nor is it restricted to the air.

In the USA, indoor air pollution is regulated by OSHA. Outdoor air pollution is regulated by state and local jurisdictions as well as the US EPA.

Industrial pollution is typically concentrated within a structure or confined space such as a mining operation.Industrial air pollution control equipment consists of dust collection equipment or dust collectors both portable and centralized. Dry type dust collectors come in cartridge style and bag or fabric style collectors and cyclones. Other types of air pollution control devices are wet scrubbers and industrial central vacuum systems.

Air cleaning devices are classified in two categories; high volume low pressure and low volume high pressure systems. There is a difference. It is imperative that the correct equipment be selected for each specific operation.

A specific operation is referred to as cutting, sanding, barrel filling and numerous other operations classified by the American Conference of Governmental Industrial Hygienists. See www.acgih.org for more information.

The industrial pollution control equipment engineer or system designer is tasked with selecting the correct filtration equipment, air mover, hood type, duct type, duct size, controls, instrumentation and installation techniques. In other words, there are many facets to consider when choosing industrial pollution control equipment.
