Heating, ventilation, air conditioning, and plumbing affects our health and well-being. Without an appropriately designed system, contaminants can become introduced into a home or business. F.E. Moran has expert designers who are experienced with choosing the appropriate system and know how to design systems so they are as effective as possible. Not only will this prevent health issues, but it will also save money on energy and water bills.


Systems

Sheet Metal Fabrication Shop

F.E. Moran’s in-house sheet metal shop makes the process of following specifications and designs with custom work seamless.  Pre-fabrication of HVAC ductwork for commercial, manufacturing, healthcare, educational, retail, and residential facilities saves building owner’s money and time.  Pre-fabrication enables F.E. Moran to spend less time fabricating on the job site, reducing the disruption to production and job site congestion.

  • Facilities Save Time and Money – when fabrication is completed off-site, facilities don’t lose unnecessary production time and the construction process in significantly reduced.

  • Customization is Simple – sheet metal is pre-fabricated on-site at F.E. Moran with easy access to designers.

  • Safer Fabrication Choice – sheet metal is fabricated off the job site in an environment designed specifically for sheet metal fabrication.  Without job site obstacles, sheet metal is fabricated safely within a controlled environment.

 

Large and Small Bore Black Pipe Fabrication

F.E. Moran has in-house large and small bore pipe fabrication.  With in-house fabrication, there will never be an issue of another project taking priority with a fabrication contractor. Pre-fabrication also improves safety conditions because most fabrication takes place off-site, in controlled conditions.     

  • Facilities Save Time and Money – Facilities are able to continue production while F.E. Moran fabricates large and small bore black pipe off-site.  With a streamlined pre-fabrication process, the project timeline is reduced, saving facilities both time and money.

  • Customization is Simple – every facility has different needs with unique environments.  With off-site pre-fabrication, meeting these needs is easy.  Fabricators have the tools and space available to efficiently customize pipes for any facility’s needs.

  • Safe Fabrication Choice – off-site fabrication decreases job site congestion, reducing the chances of having a job site accident.

 

Medical Gas Piping Systems

Application:

Medical gas piping systems are responsible for supplying oxygen, nitrous oxide, nitrogen, medical compressed air (MCA), and carbon dioxide to designated areas of a healthcare facility.  F.E. Moran personnel are heedful to the needs of a medical facility, and make all the precautions to ensure the system is clean and safe for all patients and staff.

  • Compressed Air (medical and dental patient and lab use)

  • Vacuum (medical and dental patient use)

  • Laboratory Dust Collection

  • Waste Anesthesia Gas Disposal

  • Gases (patient, laboratory, and equipment use)

 

Operation:

Through a centralized medical gas pipeline system (MGPS), certain gases are distributed throughout a healthcare facility, providing either a hygienic environment or patient safety and comfort.  The most common distributed medical gases are compressed air, vacuum, laboratory dust collection, waste anesthesia gas disposal, oxygen supply, nitrous oxide supply, nitrogen equipment supply, and carbon dioxide supply.     

 

Special Considerations:

MGPS’ must be installed by an experienced professional.  Cross contamination of the gas pipelines could be catastrophic. Currently, there are no national standards for inspection procedures; however, medical gas piping, if corroded or filled with condensation can cause serious harm to a patient.  Facilities should have medical gas piping inspected, tested, and maintained to ensure patient safety.  


Heating

 

Central Heating

Application:

Central heating is used in applications that utilize a duct system.  The furnace heat is distributed throughout the building via ducts.  Central heat is the most used form of heat in the commercial, retail, and food service industries (epa.gov).  Approximately 86.7% of the occupied homes in the United States are heated via central heating (census.gov).  

 

Operation:

Central heating takes place in a central point, such as a furnace or mechanical room, and then the heat is distributed throughout the building through ductwork.  The heat source is created through the ignition of natural gas, propane, or fossil fuel or it can run on electricity.   

 

Special Considerations:

Central heating can have fluctuations in temperature throughout a room; there is no option for zone temperature control; and central heating can carry allergens through the ducts if the ducts or furnace are not properly maintained.

 

Boiler

Application:

A boiler, furnace, or heat pump can be used in any application.  However, there are a few differences.  Boilers use hot water distributed throughout the building in pipes to provide heat.  This has the advantage of zone controls.  Each room can control its own heat.  Another benefit is, without ducts, allergens cannot be distributed throughout a facility.  These benefits make boilers the best choice for facilities 5,000 square feet or larger.  According to eia.gov, boilers are the most popular form of heat for educational and large commercial buildings.  

However, because there are no ducts for heat, ducts will need to be installed for air conditioning.  Boilers come in various sizes to accommodate different facility types and sizes.  There are several different types of boilers to choose from based on each individual application:

  • Fire Tube Boiler

  • Water Tube Boiler

  • Packaged Boiler

  • Fluidized Bed Combustion (FBC) Boiler

  • Atmospheric Fluidized Bed Combustion (AFBD) Boiler

  • Stoker Fired Boilers

      • Spreader Stoker

      • Chain-grate Stoker

      • Traveling-grate Stoker

  • Pulverized Fuel Boiler

  • Waste Heat Boiler

  • Thermic Fluid Heater

 

Operation:

A boiler is a sealed, usually steel, vessel that contains the combustion of one of several types of fuel including wood, coal, oil, or natural gas.  The fuel heats water, which is then sent through pipes to radiators or to a fan coil unit that will heat air.

 

Special Considerations:

A boiler will need to be bled of excess air periodically.  A dehumidifier may be needed to counteract the possibility of a higher humidity derived from the boiler.

 

Furnace

Applications:

Furnaces can be used to heat most facilities.  They are the most popular form of heat for residential and smaller commercial buildings (1,001 – 5000sf) due to the low cost and dual-use ducts for central air conditioning.  According to eia.gov, furnaces are most popular in office buildings, retail, service, and food service buildings.


Operation:

When the temperature in the facility falls below a predetermined level, gas flows into the electronic ignition system.  The combusted gas rises past the heat exchanger and through a vent leading outdoors.  A motor then pulls air into the furnace from an exchange.  This air passes the combusted gas, heating the air.  From there, the heated air is distributed throughout the building through the ductwork.

 

Special Considerations:

Furnaces have some maintenance that must be done in order to keep them working efficiently.  Without regular maintenance, a furnace can cause numerous problems.  Ductwork could leak in the seams, reducing heat efficiency.  If filters aren’t replaced, allergens can be distributed throughout the building through the ductwork.  Dirty burners cause gas not to burn thoroughly.  If gas does not burn completely, it will result in less heat and higher gas bills.

 

Heat pump

Application:

Heat pumps are an efficient form of both heat and air conditioning for small buildings.  They are the most popular form of heat in healthcare facilities.  Heat pumps are a good choice for those who want an energy efficient system.  They distribute heat evenly and are quiet.

 

Operation:

Step 1:  A coolant cycles through the heat pump system and collects the surrounding heat.  The absorption of the heat causes the coolant to turn into a gas.   

Step 2:  The compressor condenses the coolant.  Now that the coolant is a gas, the condensing process increases the temperature of the gas.

Step 3:  The heated coolant now moves through the water in the radiator.  While the gaseous coolant is circulating, it is radiating its heat into the environment.  Through this process, it loses its heat and becomes a liquid once again.

Step 4:  The coolant runs through the expansion valve and begins the process again.

 

Special Considerations:

Heat pumps are best for climates that remain above 30 degrees.  Below 30 degrees, the ambient outdoor heat is no longer abundant enough to pump into the home once the temperature reaches below 30 degrees.  A backup heating system may be needed for climates that reach freezing temperatures.  Heat pumps must have regularly scheduled maintenance to guarantee the effectiveness.  Heat pump installation takes in-depth expertise due to the complicated system set-up.  It is essential to hire an experienced technician to install a heat pump correctly.

 

Ventilation System

Application:

According to the Occupational Safety and Health Administration (OSHA), ventilation is one of the most important controls available to manage air quality in the work environment.  Ventilating is the replacement of air in an indoor environment for the purpose of improving the air quality.  Air quality improvement includes temperature, oxygen replenishment, moisture removal, odor, smoke, heat, dust, carbon dioxide, or bacteria removal.  Air ventilation includes exchanging the indoor air with outdoor air, like in the air conditioning process, or circulating the air within the building.  The ventilation process occurs in either mechanical/forced or natural ventilation.  Some form of ventilation is needed for any type of structure.     

 

Operation:  

Mechanical/forced ventilation utilizes an air handling unit (AHU) to circulate air.  The AHU consists of a blower, heating/cooling elements, filter racks/chambers, sound attenuators, and dampers within a container.  The container connects to the ductwork and filters the air conditioning and heat before it is distributed and vented throughout the building.

 

Special Considerations:

Duct design should be smart.  Ducts that are too small for the space results in loud ambient fan noise.  Ducts that are too large, result in wasted material spending and an inefficient system.  Finding the right balance will result in minimal material costs and efficient ventilation.


Air Conditioning

Central Air Conditioning System

Application:

Central air conditioners can cool any sized building through a duct system.

 

Operation:

Air conditioners are composed of three main parts:  compressor, condenser, and evaporator.  The condenser and compressor are located outside while the evaporator is located inside of the building.  The refrigerant arrives at the compressor in a cool state; it then becomes hot, compressed, and gaseous and flows to the compressor.  A fan near the compressor cools the fluid and it becomes a liquid again and goes to the evaporator.  In the evaporator, the fluid’s pressure drops and it evaporates into a gas.  The gas evaporates and extracts heat from the air.  A fan connected to the evaporator moves the air around the room.  Hot air weighs less than cold air, so the hot air rises to the ceiling where it is pulled into a vent.  The hot air is pulled into the air conditioner and through the ducts where it is cooled.  The cooled air is distributed via ducts throughout the building.       

 

Special Considerations:

Central air conditioning requires the entire building to be sealed.  If heat comes into the building, it will keep the air conditioning system running, driving up energy costs.
