Mechanical Systems Made Easy

Mechanical systems are simple systems often constructed for a single purpose. They generally have a few parts or subsystems. Simple mechanical systems are around us in our daily lives. They are constructed in a way that their parts are used in symphony with each other toward a common goal. Their operations are transparent to us unless we specifically examine them. They effectively maintain the human environment in a comfortable equilibrium.

Any building service using machines is a mechanical system. The plumbing, elevators, escalators, heating, and air-conditioning systems are part of mechanical solution services.

This system of mechanics was introduced because to meet floor space demand the designing team started including electrical and HVAC (heating, ventilation and air conditioning) engineers in the early 20th century.

Some popular mechanical solutions services provided are as follows:
Mechanical constructions – These include detailed project overview, execution detailing schedules, labor allocation, budget and cost control measures that cover the construction of hospitals, schools, apartment buildings, stores, warehouses, mines, and paper mills.

Mechanical contractors – Licensed pipefitters, welders, boilermakers, millwrights, commercial and industrial plumbers, plastic fabricators, metal fabricators, commercial and industrial heating, and cooling experts and welders comprise these contractors.

Mechanical Insulation –

Millwright – This is a transition system involving dismantling, erecting, aligning, and adjusting of machinery. Machines used here are dryers, cranes, storage rack system, conveyers.

Plumbing – This is mainly done for maintenance purpose.

Air Conditioning – This solves commercial air conditioning and industrial process refrigeration problems.

Air Distribution – This form of mechanics controls the quality of indoor air. Due to negative air pressure and uncontrolled air circulation, commercial and industrial buildings suffer from air distribution problems, such as humidity, fumes, inefficient heat transfer, hot and cold spots, heat loss, dust drafts, and stratification.

Heating – Heating solutions using gas, water, electricity, and steam are used to heat up units.

Insulation – The life span of industrial equipment, such as boilers, valves, turbines, industrial piping, ducting, are increased.

Panel Fabrication – This involves custom designing, engineering, and fabrication of panels for commercial and industrial projects.

Pipe Fabrication – This means fabricating custom length pipes and assemblies for both commercial and industrial projects.

Industrial Duty Exhaust Ventilator

Pollutants such as pesticides, harmful gases, smoke, pet dander, lead, asbestos, dust mites, paint fumes, grease etc get released into indoor air due to daily activities such as cooking, smoking, burning fuel, bathing, renovating etc. In addition to these pollutants, activities such as bathing, cooking, and washing also release excess moisture in the air and make indoor air extremely humid. If not ventilated adequately, these added pollutants and increased moisture levels can decrease the quality of indoor air greatly, thereby leading to various problems such as:

Health problems including asthma, allergies, nose bleeds, skin rashes, headaches, nausea, and other breathing disorders. In fact, according to the Environmental Protection Agency, a large percentage of the over 20 million annual asthma cases in the US alone can be attributed to bad indoor air quality.

– Split, warped and rotted furniture due to excess humidity.
– Cracked and peeling paint on the walls.
– Formation of fungus, mold spores, and mildew, which in turn lead to severe health problems.

Exhaust fans are very effective at any building ventilation. Without proper ventilation, the air inside your home can get filled with harmful contaminants and disease causing pathogens.

An exhaust fan is a mechanical ventilation device that helps to draw out stale and impure air from your home and bring in fresh air, thereby improving the quality of indoor air. Exhaust fans are typically ducted to the exteriors of your house, through which bad indoor air can effectively be removed from your living space.

Exhaust fans are classified into various types, mainly depending on the type of mount and the location where you need to install the fans. The different types are:

1. Ceiling Mounted Exhaust Fans: As the name suggests, ceiling exhaust fans are those which are installed in the ceiling. Such fans expel stale air from your home upwards through the roof. The fan is connected to ducting, which is exhausted outside the home via an external vent, like a roof cap or soffit exhaust vent.

2. Inline Exhaust Fans: Unlike ceiling exhaust fans that are installed directly into the ceiling, inline exhaust fans are typically mounted in-between ducting, hence the name inline fan. For instance, if you wanted to ventilate an area that did not have clearance or space for a ceiling mount fan, you would make use of inline exhaust fans to ventilate such areas. The exhaust fan would be placed in between the ductwork and the stale air would travel through the ducts and ultimately be expelled from your home. Since inline fans are not mounted directly to the ceiling, they are very quiet. When installing an inline fan, to reduce noise, we recommend using an insulated flex duct that is at least eight feet long from the intake port on the ceiling to the inline fan.
Inline exhaust fans are ideal for exhausting areas or rooms where you cannot, or do not wish to install the exhaust fan directly. Since these types of exhaust fans are mounted in remote areas, they are also referred to as remote mounted exhaust fans. Inline exhaust fans can either be single-port (exhausting from a single area) or multi-port (exhausting from multiple areas).

3. Wall Mounted Exhaust Fans: These exhaust fans are installed on walls. Since they are installed on exterior walls of the home and not on interior walls, the stale air has a direct route to the outside of your home and thus no duct work is required in installing these exhaust fans.

4. Combination Exhaust Fans: Exhaust fans are also available as combination units. You have the choice of a fan-light combination where the exhaust fan provides illumination as well, or heat-fan-light combination wherein you get a heater, light and ventilating fan all in a single device.

5. Exterior Remote Mounted Exhaust Fans: While most other exhaust fans are installed inside your home and push stale air out, exterior remote mounted fans are installed outside your home and pull out stale indoor air instead of pushing it out. The main benefit of these exhaust fans is that regardless of however noisy they are, most of the noise remains outside your home.

6. Kitchen Range Exhaust Fans: These fans are mounted inside the range hood over your kitchen stove. Such fans not only help to rid your kitchen of stale air but also help to expel bad odors and reduce moisture levels in your cooking area.

These several types of exhaust fans can be used for complete ventilation of your bilding including intermittent local ventilation for baths, kitchens, dryer rooms; continuous whole building ventilation, and for exhausting hard-to-air spaces such as crawl spaces, attics, and basements.

Thus, by using exhaust fans to ventilate your building efficiently and completely, thereby improving indoor air quality, you can avoid of all these problems.

When sizing an exhaust fan that does not open directly to the outside but is ducted, it is important to ensure that the exhaust fan has the capability to move stale air throughout the duct and ultimately to the outside. Here, we first need to understand what static pressure and equivalent duct length is.

Inside every duct, there is a constant pressure being exerted at any point from all directions. When an exhaust fan moves air through the duct, the air counters resistance from this pressure which is known as static pressure. Thus, an exhaust fan has to have the ability to overcome the static pressure in a duct so as to effectively duct stale air to the outside of your home. This can be done by calculating the equivalent duct length of any duct.

* University, Medical Research, Defence Labs, Fume Hoods OEMs, Pharmaceutical Labs

On most campuses there is a certain number of fume hoods that are used for various acids testing to break down materials for analysis. HCl and Perchloric Acid are the ones used most commonly. Fume hoods and Chemical resistant fans are needed.

* High Technology Semiconductors, PCBs, and Photonics

Chip makers use acids to clean metal before they mount thin film on the metal upon which they lay circuitry.

* Printed Circuit Board Industry

FRP fans are frequenly used for clean rooms.

* Waste water and Sewage Treatment Plants

Hydrogen Sulfide builds up (H2S) in sewage plant facilities and causes an odor problem that has to be treated. Depending on the size of these stations corrosion resistant fans are needed. This gas can also be very volatile and will require explosion proof motor and static grounding of the fan housing by graphite impregnation that NISCO can provide too.

* Salt Air and High Humidity Environments

Any facility near the salt air is also a good place for plastic fans and the humidity will eat through metal fans.

* Steel and Wire Manufacturing

As the steel comes in and sits at these plants impurities and scale develop on the steel or the wire that needs to be cleaned off before the wire or steel can be properly worked with. Acid baths are needed for this and the corrosive fumes coming off these aced baths are highly corrosive…

* Stainless Steel and other Metal Production Facilities

In tha annealing and Pickling process acid baths are used to strip scale off the steel after the annealing process that smoothed out grain patterns that may have formed during the annealing process. Later on acids are used again to support oxidation.

* Chemical and Petrochemical Industries

* Jet Engine and Power Plant Turbine Manufacturing or Servicing

Molted Salt tanks are often used here to descale metals coming out of hot furnaces. Pickling and cleaning of titanium which is used in Jet engine parts also utilize acid baths as does nickel plating.

* Electroplating and Metal Finishing

These industries use fiberglass fans and fume scrubbers.

* Scrubber OEMs and Designers

FRP fans are standard components in fiberglass srubber designs.

* Industrial Galvanizers

* Printing Press Service Shops

* Chromatography

* Food Processing

Often in the food processing industry they wash equipment down with acids and other corrosives. Also they use fans for the humidity that builds up from the drying process of foods.
