Portable vs. Discrete Chiller

Posted Friday, 22 June 2018 08:52 by Martin King in HVAC Business

What is a portable chiller ?

A portable chiller is an alternative to a central chiller system. Portable chillers are usually small units that are mounted on wheels and can be rolled from one place to another inside a facility. But not all portable chillers are actually mobile. Another word for a ‘not so portable’ chiller is a discrete chiller. A discrete chiller can have an outdoor remote condenser (which is not portable) or an elaborate ductwork system to cool down warm air in the summer and provide heat in the winter. A discrete chiller can provide up to 50 tons of cooling capacity, which can make each unit quite large. Discrete chillers can be used to cool a single process or processing machine.

Benefits of a Discrete Chiller:


The number one benefit of using a discrete chiller, rather than a portable chiller, is flexibility. With a discrete chiller, you can get more for a lower price. These chillers can eliminate the need for having both a central system and separate temperature control units that are usually needed to change fluid temperature provided by the central system. In the long run, this process will save you money in operations. A discrete chiller also allows you to select the best temperature for each process. If you change to a new mold, you simply change the temperature to accommodate that mold's needs.

Low Risk

If there is a problem with a discrete chiller, only one machine will be affected rather than every machine in the plant. With central chilling systems, if a problem occurs, multiple circuits can go down at the same time, which can badly affect production and your bottom line.

Easy Installation

Discrete chillers take a fraction of the time to produce, and can be used anywhere. Many discrete chillers are always in stock and require only power and hoses to get into production. Central systems require, on the other hand, expensive piping networks and long lead times to get up and running.


Discrete chillers can expand easily when your business does. If your central cooling system hasn't been able to grow with system expansion, growing a system can be expensive and difficult to install. With discrete chillers, expanding is easy! A processing machine can be added to your discrete chiller, expanding the capabilities of your machine to match your growing business.


Discrete chillers use many more parts than a central system, such as increased compressors, pumps, valves, and electrical controls, but all of these parts are much smaller on a discrete chiller. When a problem occurs with a discrete chiller, repairs and replacement are much cheaper and less complex than a full unit. When deciding to go with a discrete or central chilling unit, you have to decide what is best for your business. Production and budget are the most important factors in this decision, and are unique to each situation.

As summer approaches and the days get warmer, we are so lucky to have the comfort of cooling machines to keep us cool on those hot summer days. Nowadays, we take air conditioners for granted, but imagine what life would be like without them.

Air conditioners were once considered a luxury, but nowadays are an essential. Air cooling systems cool our homes, businesses, and other buildings on a daily basis. In fact, air temperature is so important to us that 48 percent of all energy consumption in American homes is a result of cooling and heating.

Like most inventions, modern commercial and residential air conditioning is a result of a series of trial and error by scientists and engineers.


In the 1840s, the idea of cooling buildings to relieve people of high temperatures came about. Experts believed that cooling was the key to avoiding diseases like malaria and making patients more comfortable. The very first cooling systems required ice, which needed to be shipped from frozen lakes and streams in the northern United States. Although effective, this concept quickly became very expensive and challenging. Experts began experimenting with the concept of using artificial cooling. The first artificial cooling machine that was created used ice and a compressor powered by wind-driven sails or steam. This was the first invention that laid the foundation for modern air conditioning and refrigeration.


Early cooling systems for public buildings were essentially heating systems modified with refrigeration equipment that distributed cold air through floor vents. In 1922, the first well-designed cooling system was installed in a theater in Los Angeles. The system pumped cool air through higher vents for humidity control and comfort throughout the building.

The following year, a theater in New York City debuted a new type of system that used a centrifugal chiller, which had fewer moving parts and compressor stages than the existing units. This breakthrough system increased the reliability and lowered the cost of large-scale air conditioners, greatly expanding their use throughout the country.


These new systems were great, but still too large and expensive for most people to have in their homes. Frigidaire was the first company to introduce a new split-system room cooler that was small enough for home use and shaped like a radio cabinet. As time went on, home cooling systems got smaller and an air conditioning unit that could be placed on a window ledge was finally designed. Window units came to the market about 1932.


Today, experts are working on the next big thing in air cooling, air conditioning (non-vapor compression technology) that does not use HFCs that harm the environment. This new technology is said to introduce a new era of cooling, and to reduce energy consumption by 50 percent.

3 Trends for the Future of Process Chillers

Posted Wednesday, 09 May 2018 10:27 by Martin King in HVAC Business


We live in a time where things are constantly changing and upgrading for the better. It all goes so fast, sometimes it’s hard to keep up with technology. The world of engineering is not different. As time goes on, advances and growth in manufacturing equipment such as process chillers will keep coming. All of these fast-paced upgrades and changes are making us at Legacy wonder…what does the future of process chillers look like?

After doing some research and visiting a few sites, here are the top 3 areas we will most likely see changes in the near future to process chillers:

Energy Efficiency:

Nowadays, everyone is making significant efforts to improve energy efficiency. With this new trend it is no surprise that many companies will be focusing their efforts on creating process chillers that meet customer's needs, but use as little energy as possible. 

Since most process chillers are used for work applications, such as MRI's, lasers, and breweries, they tend to be used for much longer periods during the day, compared to non-process applications such as air conditioning. As energy costs start to rise, manufacturing companies will look for more energy efficient and environmentally responsible mechanical equipment.

Legacy Chiller Systems anticipates growing demand for innovations in design that are cost effective, flexible in application to differing customer needs, and easy to maintain.

Preventative Maintenance:

For HVACR contractors, building facility managers that are in charge of maintaining mechanical equipment face an ongoing challenge of finding good workers to do this type of work. There has been a significant shortage of HVACR technicians over the past few years, and the shortage is expected to grow moving into the future.

As service providers are getting pressed with too much work and not enough qualified workers, one of the first areas to cut costs in is maintenance. Cutting down on maintenance techs and routine scheduled equipment maintenance can of course cause huge problems downs the road. Skipping out on maintenance can cause much more expensive emergency services needed down the road. The next generation of process chillers (especially those used in important life or death scenarios such as MRI or CT systems) will have the capability to tell us when there is trouble coming. This advanced notice will give service providers the time needed to plan ahead, and potentially fix the problem before it turns into something major and more costly. This new technology can also help reduce yearly maintenance costs by as much as 30%.

Remote Access and Communication:

Just like the amazing advances we have seen in computer networks, critical process equipment must also be able to access the outside world securely. HVACR manufacturers should offer these technologies as optional or even as standard features on all equipment.

New Tax Law Benefits Chiller Industry

Posted Monday, 30 April 2018 10:54 by Martin King in HVAC Business

Everyone knows that a quality process chiller is not cheap! Unfortunately, these machines are a huge necessity in many industries.  Companies will look for more cost effective ways to keep their chillers running to full potential for as long as they can, rather than purchasing new equipment. Over time, choosing to hold off replacing a process chiller that is heading towards the end of its usable life can end up costing the owner more, if you consider money spent repairing an old machine vs. investing that same hard earned money in something new.

Thanks to the recently-enacted Jobs Act of 2017, which came into effect January 1, 2018, process chillers can now be immediately expensed as compared to needing to depreciate the capitol costs over as many as seven years.

What exactly does this mean?  For example…in the past if a business owner was to install a new process chiller unit for a total cost of $14,000 (equipment and labor for installation), the owner could only claim approximately $2,000 in depreciation expense each year over a 7-year period. With the new tax law the same owner can now deduct the entire $14,000 cost of the equipment immediately at the top marginal tax.  

Legacy Chillers is a quality manufacturer of process chillers.  We also assist current customers in need of equipment upgrades.  If you haven't already, please share this new information with your customers and clients to help them see how the new tax laws can save them money.

The Manufacturing Comeback in America

Posted Tuesday, 06 March 2018 09:59 by Martin King in HVAC Business

It seems like almost every day there is news predicting the downfall of America's economy.

But most of us don't realize the ways which America is gaining rather than losing global influence. 
There are many great things happening in America and with our economy. The biggest growth can be found in the manufacturing industry. 

Many things have contributed to the recent rise in the American economy.  Lower energy prices, innovative information technologies, 
and advances in robotics all have influenced growth. The growth of material science is impacting the manufacturing revolution, and are predicted to make 
America's industrial sectors the most competitive in the world.

The Change:

One of the biggest changes we've seen is in the energy sector. The United States already has the second-largest shale gas reserves 

in the world. Recent developments of new technologies are predicted to grow the sector even more. Fracking, in which gas and oil is 
extracted from shale rocks by fracturing them, is driving an energy boom in the U.S. that will soon lower natural gas prices and give American manufacturers a unique competitive advantage.


The use of robotics in manufacturing plants is also predicted to increase efficiency and precision in the manufacturing industry. 

As robotics continue to expand and grow in America, the cost to produce them is shrinking. 
As the use of robotics grows, a decline in job creation will naturally follow. Machines are likely to replace many workers, but America's dominance in computing and electronics
will create an edge in the automation of manufacturing processes.

New Materials:

The emergence of new materials that use nanotechnology and biotechnology will offer products and production unique to America. 

Applying the technology to carbon nanotubes and grapheme has allowed the growth of high-performance transistors and light composite materials, which 
can speed up the diagnosis of illnesses, detect contaminants, and provide accurate glucose monitoring.

Many large companies such as General Electric are already relocating operations from Asia to Silicon Valley to take advantage of America's information technology. 
Moving production back home will create savings in transport costs, and benefit from the lower energy costs at home.

At Legacy Chiller Systems, all of our parts and products are produced and manufactured in the USA.
