Why Should Your Company Install an Energy Recovery Unit?

Energy Recovery UnitDesigned to recover up to 80% of the energy expended, an energy recovery unit is an ideal way to make your company’s monthly expenses lower.  It can be used as a standalone module or can be attached directly to the rooftop, thus allowing it to accommodate more outdoor air quantities. Even better, when opting for the rooftop installation you can often go with a smaller unit capacity, which means a lower installation price.

The energy recovery units (ERU) are ideal for a long list of industries – some of these include hotels, hospitals, sports halls, office buildings, seminar rooms, swimming pools, paint spray booths and many others. At MJC, we offer several types of energy recovery units, so there is certain to be one that fits your unique needs and building design. Below is a list of our ERU types and a brief description:

·      Fixed Plate ERUs – Designed with no moving parts, compact, outstanding corrosion resistance, compatibility with high temperatures applications, the fixed plate design is often the best choice in ERUs for a company.

·      Sensible Plate Energy Recovery – Known for trouble free operation, reduced noise and minimal maintenance, lightweight, compact design, no moving parts, separate air streams and no cross contamination.

·      Enthalpy Plate Energy Recovery – Like the others, the Enthalpy Plate Energy Recovery boasts no moving parts, minimal maintenance costs and reduced noise.

·      Energy Recovery Wheels – Designed to recover sensible and latent energy, it will not promote the growth of mold or bacteria, has increased fire protection and is easy to maintain.

But if you are on uncertain about whether or not an ERU is needed for your business, then consider these additional benefits in having one added to your location.

1.     Fresh air – During the winter, the air can get rather stale as doors and windows are not opened as often. An energy recovery unit will circulate the air keeping it fresher and more breathable.

2.     Healthier employees – As a business owner, you depend on your employees to help you succeed. If they are out sick; the work production is affected. By swapping out the air, you are ridding your place of business of germs and bacteria which creates a healthier environment and lowers risk of winter colds being circulated throughout the office.

3.     Save money – The biggest benefit is the money saved. An ERU eases the strain on your HVAC system so it doesn’t have to work as hard, thus extending the life of the unit. In fact, studies show that energy bills drop by as much as 40% when an ERU is in use.

An energy recovery unit is a must for any commercial space. It combines energy efficiency with ease of maintenance, better health and lower costs to make it a wise decision. If you have questions about how an ERU can benefit your space, give one of our MJC, INC. specialists a call today.

Choosing the Right HVAC System for Your Place of Business

MJC HVAC systems home 2aDid you know that HVAC systems count for 39% of the energy consumption in commercial buildings in the US? This fact alone, has been enough to propel companies to look for ways to design a more energy efficient method of keeping their location. But, when you also consider that use of high performance heating, ventilation and air equipment can save between 10% and 40% in energy and emissions, then looking for a way to stay comfortable, but also save money is important.

At MJC, we offer several types of HVAC systems. These range from outdoor units, portable and rental units, custom design units and gas-fired units for energy efficient systems and produce direct, indirect or heat injector systems, as well as our very own, patented Heat Injector – the most energy efficient direct gas fired heat technology available.

Considerations in Choosing an HVAC System

As you begin the process of selecting an HVAC system that will work for you, there are a number of concerns that need to be addressed:

·      Consider the various aspects of the building. From lighting to square footage, and how the space(s) will be used, to systems in the building that will generate more heat, take a moment to review the building as a whole.

·      Determine your energy goals as soon as possible. If your goal is to merely meet the energy requirements, rather than use less energy then, then your HVAC system needs will be different. This difference will be reflected in both type and size of system.

·      Plan for expansion but don’t automatically buy for it. While you may expect your HVAC needs to change in the future, it is better to buy for the needs of today. Otherwise, you will be wasting money on a system that may very well be obsolete by the time you make the space expansion.

·      Plan now for maintenance and operation needs. When you select an HVAC system, keep in mind that it will require a certain level of maintenance in order to run at its full potential. You will need someone onsite who understands the various components of your chosen system.  Ideally, these people will be trained to understand the controls and equipment needs, so that they can keep your HVAC unit running properly.

So, which type of system is best for your needs? If you don’t know, then talk to one of our MJC representatives. They will be happy to visit your location and help you assess what will be best. We understand how important it is to you to have a system that is both energy and cost efficient, and will be happy to answer your questions and concerns.

6 Tips for Selecting a Commercial HVAC System

MJC Inc Energy WheelsIf you are building a new business location, or perhaps considering upgrades for an existing one, chances are, you will need to think about the type of commercial HVAC system to install. After all, you want to keep on budget, not just in the purchase and installation phase, but also in the future as you pay energy costs each month.  But what should you look for in selecting an HVAC system? After all, that is not something that most of us have a great deal of experience in!

6 Tips for Selecting a Commercial HVAC System

As you begin the search for the HVAC system perfect for your business, don’t hesitate to ask questions. Talk to several HVAC specialists, visit other companies and find out what they have and why, and then make an informed decision. As you do your due diligence, the following tips will help.

·         Efficiency – As with any business investment, cost will always be a determining factor. But remember, that it is not the only factor. Perhaps one of the most important things to look at is the efficiency of a particular brand or type of HVAC system. Be sure that a particular unit or style will not just heat and cool, but do so in a way that works with the design and usage of your space.

·         Reliability – It isn’t truly saving you time and money if the system chosen requires frequent updates, repairs, and cleanings. Select a system noted for its reliability and minimum maintenance needs. A good way to learn how dependable a system is will be talk to others who have the same set up.

·         Size – Bigger is not always better. You don’t need a system that is larger than necessary as it will actually cost more and be less efficient. Be sure that your company’s HVAC system is the right size for the number of people who will be in your building as well as the square footage of your facility.

·         Specifications -When asking for a quote on an HVAC system, be sure to ask for one based on specifications for a standard efficiency system as well as a high efficiency system including life cycles. Typically, if the lifecycle cost is less on the high-efficiency unit, this will be the system to purchase.

·         Recycling –To minimize wasted energy, consider having a system that recycles the exhaust air stream and turns it into incoming fresh air.

·         Building Type –Areas such as warehouses and garages often do best with a radiant heating system while facilities that do onsite cooking or have heavy equipment in use do well to have a heat recovery system as a way to capture “wasted” heat and use it to offset facility heating and cooling costs.

Saving Money with the MJC Air to Air Plate Energy Recovery Unit

mjc air 2 air 2When it comes to one’s working environment it is important that it be the best it can possibly be. This is often done through providing the appropriate workspace, the tools needed and most importantly, ensuring that comfort levels meets industry standards. Consequently, the HVAC system that you use needs to meet a variety of standards. The MJC Air to Air Plate Energy Recovery unit is designed to meet and exceed the industry standards, thus guaranteeing that you and those with you work are best able to perform their jobs.

 

The Benefits of the MJC Air to Air Plate Energy Recovery Unit

Energy Recovery
For comfort, health, and safety, places where people work require adequate ventilation. However, ventilation air is very expensive to condition from an energy standpoint. When outside air for ventilation is brought into a building or a space, all, or most of it, has to be exhausted to prevent pressure build up inside the building. The building owner or tenant has already paid to heat or cool the air that’s being exhausted, so a great deal of money is spent on energy costs. As such, it is vital that business owners or property managers look for ways to save money through energy recovery.mjc air 2 air 3

Energy Savings
As we know, ventilation air is very expensive to heat, cool, and dehumidify. Re-circulated air that returns to the unit from the conditioned space is typically 75 F and 50% relative humidity. To cool and dehumidify the air, the air conditioning unit cools it from 75 F down to 55 F and removes moisture at the same time.

Ventilation air brought in from the outside on a hot summer day can be from 92 F to 105 F or higher if the building is located in the desert southwest. It takes a lot more energy to cool air from 92 or 95 F to 55 F and that’s why energy recovery makes so much sense.

Energy recovered by the MJC Air to Air Plate Energy Recovery Unit is used to cool down the incoming air from 95 F to around 81 or 82 F in most applications, which reduces the work the air conditioner has to do, thus saving utility costs. These units work the same way for wintertime heating by recovering heat and moisture from the air being exhausted and adding it to the incoming ventilation air.

Moisture & Comfort
Much of the discomfort we feel indoors, comes from having too much or too little moisture in the air. The MJC Air to Air Plate Energy Recovery unit removes moisture from the incoming air in the summer and adds moisture to the incoming air in the winter; saving energy and making the occupants feel more comfortable.

Lower Maintenance Cost
At the heart of the MJC unit is an air-to-air plate heat exchanger. Unlike “wheel” type units, the air-to-air plate heat exchanger has no bearings, belt, gears, or motor and under normal use can be cleaned with a shop vacuum.

What is the Air Turnover Unit and How Does it Help?

air turnabout 2At MJC, we are always looking for ways to make heating and cooling easier, and more effective. We work hard to ensure that every piece of equipment offered goes above and beyond the industry requirements so that you get the best service possible. It is with that goal in mind that we offer the MJC Air Turnover Unit.

Never heard of an Air Turnover unit? Then allow us to explain it to you. An Air Turnover unit is a large air handler, used to supply and return large quantities of air without ductwork. The process is simple – a mass of air is discharged at or near the top of the space and the same quantity of air is returned from floor level. The air mass exchange results in a turnover of space volume. This design gamf.net makes heating and cooling large spaces more effective and efficient for spaces such as warehouses, manufacturing facilities, super mario distribution centers, and indoor sports training facilities.

The ideal application is to use fewer, larger units for both heating and cooling applications. Doing so results in the following benefits:

As compared to unit heaters an air turnabout unit uses:
· Less natural gas, hot water or steam piping
· Fewer electrical circuits
· Fewer vents and roof penetrations for gas fired heating
· Less labor

As compared to conventional heating and cooling systems the air turnabout:
· Fewer units
· Fewer electrical circuits
· Less natural gas, hot water or steam piping
· Fewer roof penetrations
· No ductwork
· Fewer condensate drains

Energy Savings from an Air Turnover Unit

The primary energy savings from an Air Turnover unit is from fan brake horsepower. Conventional Roof Top units use forward curved fans and Air Turnover normally uses airfoil prop fans. Since an Air Turnover unit is not ducted, there is less overall static and less fan horsepower is needed.

· FC fan operating at 2.00” TSP = 25 HP
· Airfoil prop fan operating at 1.2” TSP = 15 HP
· 40% Reduction in fan HP.

How Can Your Company’s HVAC System Benefit from Weatherization?

"Glass wool Insulation"There are many methods a company might implement to save money, but perhaps one of the simplest is by looking for ways to get the most from the HVAC system. Your company spends a significant portion of the monthly budget on heating and air conditioning, but what if you could maintain the comfort level, but lower the spending? One such way is with weatherization.

Weatherization is defined as the practice of protecting a building and its interior from the elements, particularly from sunlight, precipitation and wind; modifying a building to reduce energy consumption and optimize energy efficiency.” Or, simply put, it is opting for a more high efficiency approach to heating and cooling.

Because warm air seeks colder air, the best way to begin the weatherization process is by walking around your building with an incense stick or bottled smoke and noting where the smoke seems to be drawn towards. Most likely, the common places will be around windows, doors, and electrical outlets; however, other common locations include floors, ductwork, fans, and vents. Once problem areas have been identified, there are several different steps that can be taken to improve efficiency. Continue reading
