City Water Bypass - The Cost Effective Backup System for Process Chillers

Posted Wednesday, 09 March 2016 11:29 by Martin King in Company Updates

The city water bypass option is available for all Legacy Chiller models, but it is often not included because buyers are unaware of its benefits. Although we do everything in our power to prevent chiller downtime, which often results in downtime of the process, there is always room for the unexpected. Power failure is a common reason that a city water bypass becomes necessary, and can be utilized in order to preserve the critical process.

We recommend that every process chiller be bought with the city water bypass option because it provides a cost effective backup system for the chiller. If the chiller goes down for any reason, the PLC recognizes that there is a problem. The city water panel will isolate the fluid from the chiller, and start flowing city water through the process, and then to a drain. In this way, the process can seamlessly continue to function properly while the chiller problems are diagnosed.


Every unique process has its own set of negative implications, including downtime and cost, when the critical process is halted. In the case of an MRI machine, if the chiller goes offline leaving the MRI without coolant, a process called “quinching” begins. After about an hour of the chiller being down, the liquid helium that is used for refrigerant will start to boil off at a rate of up to $1000 an hour. In cases like this, having a city water bypass preserves the function of the MRI, while saving money and preventing downtime.

How Does the COP21 Conference Affect Your Business?

Posted Tuesday, 05 January 2016 14:33 by Martin King in Company Updates

Paris UN Climate Conference

"The Paris UN Climate Conference represents a historic opportunity to put the world on course to meet the climate change challenge. The world needs a new model of growth that is safe, durable and beneficial to all. COP21 seeks to delivera clear pathway with short and long term milestones, and a system to help us measure and increase progress over time until we get the job done.  The Paris Agreement is not only possible, it is necessary and urgent. We are counting on everyone's contribution."

-Christiana Figueres, Executive Secretary UNFCCC

Recently, there has been a lot of media attention surrounding the conference that was held in Paris from November 30th to December 12th of this year. The 2015 United Nations Climate Change Conference, being referred to as COP21, was a gathering of 195 countries with one purpose: To find a way to lower carbon emissions in an effort to limit global warming to 2 degree Celsius. The result of the conference was the Paris Agreement, a controversial document that attempted to be universal, taking into consideration the strengths and weaknesses of all countries involved.

Key Decisions:

1. Temperature Goals
It was decided that all countries should strive to limit their carbon emissions in an attempt to limit global warming to 2 degrees Celsius. The long-term goal is to only emit what the natural resources of your country can absorb, through the use of things like forests that absorb greenhouse gases.

2. Revision
Every 5 years, updates will be made to the policy plans to keep them on track.

3. Carbon Reducing Projects
"The agreement establishes a "mechanism to contribute to the mitigation of greenhouse gas emissions and support sustainable development", and paves the way for voluntary co-operation between countries in meeting their pollution goals." (Fairfax Media)

4. Transparency
Governments in attendance agreed to a framework in which detailed records would be kept of what they buy and what they burn, in an attempt to provide transparency to their efforts. Developing countries were given lower requirements, and there aren't any punitive regulations in place yet. "An agreement that required actually legally binding targets would have many countries unable to participate," said Todd Stern, US Special Envoy for climate change.

5. Finance
Developed countries are encouraged to help developing countries financially, paying for policy implementation that would reduce pollution, as well as adapting to the effects of climate change, which are sometimes devastating.

So, what does this mean for your business? According to Harvard Business Review, "As Scarborough says, "Reducing emissions while still growing as a company is the defining business challenge of the 21st century… There's a sense that COP21 will be - must be - the transformative moment the world needs." As consumer's preference for sustainable products provided by "green" businesses continues to develop and grow, the companies that respond with innovation will benefit greatly. It is important to see these changes as an opportunity.

Legacy Chiller Systems is taking this opportunity, joining the high-efficiency movement...

Medical Imaging: The Growth of An Industry

Posted Wednesday, 18 November 2015 13:33 by Martin King in Company Updates

X Ray Hand

Medical imaging equipment, such as CTs, MRIs, PET scans, and ultrasounds, are key tools in helping medical professionals observe the inner workings of the human body, without actually going inside. While some use magnetic resonance, others use x-ray technology — and all are essential to diagnostics and therapeutics. 

As the medical industry changes and develops, aided by new technology and advanced medical techniques, another industry that is experiencing growth is medical imaging. Whether a patient enters the hospital for trauma care, or is simply checking on an ailment, the diagnostic use of medical imaging significantly decreases the need for exploratory surgery. It also helps with shorter wait times and fewer hospital admissions. As a result, the medical imaging industry is seeing steady growth. 

A report by the Transparency Market Research (TMR) recently announced a study based on the global medical imaging equipment market, where it is anticipated to develop at a CAGR of 5.4% between 2013-2019, and will reach over $35 billion by the end of 2019. Furthermore, the study attributed this growth to the global geriatric population increase, which is associated with far more cases of cardiovascular disease, as well as disorders associated with brain, lungs, and the buccal area. 

Although a large portion of the global market revenue for the medical imaging market is currently in North America, China, and the Middle East, it is expected that developing economies will play a large role in the growth of the industry. 

Some of the factors encouraging the growth of this industry include the increased pressure to reduce healthcare costs, causing the healthcare sector to change its strategy and priorities. According to Frost & Sullivan, more focus is being placed on developing IT solutions in order to optimize processes:

"They expect that in the future manufacturers of medical technology and imaging systems will primarily develop and produce inexpensive, energy-saving, and ergonomic medical equipment that requires little maintenance and involves less potential risk."

- Frost & Sullivan (

Legacy Chiller Systems has heard the needs of the market, and is responding to them. Our new line of high-efficiency process chillers will address these specific areas for growth, with energy savings of up to 60%. Self-diagnostics mean that hospitals will save on repairs, and labor for technicians. We are joining the team, and want to be part of the growth of this industry as it evolves and changes for the better.
