Is Your Chiller Having a Heart Attack?

A heart attack begins when blood flow to a part of the heart muscle becomes blocked. A fatty material, called plaque, builds up on the walls of the coronary arteries.

Your chiller could be experiencing an event similar to a heart attack.

Goodway goes for the gold. And wins, twice!

DDA_GOLD_2013-RGB-72dpiJust an update because, well, we’re beaming with pride here. Goodway has won two gold Dealer Design Awards from The News, a favored trade publication in the HVAC industry. The two products receiving the highest honors are the following.

CC-400 HiFlow

CC-400 HF. This portable coil cleaner is designed to clean thick coils, up to 8″ thick without damaging them. It outputs 400 psi of cleaning power at an incredible 3.0 gallon per minute of flow rate to deliver the perfect combination of pressure and flow to deep clean thick, nasty dirty coils. In fact, it took us three years to develop the custom pump and design that would accomplish this feat. There’s simply nothing like it on the market today. It also includes an integrated siphon to pull in CoilShine, our foaming alkaline coil cleaner that leaves coils, shiny and smelling great.

RAMPRO Tube Cleaner

The other product to win this important accolade was the RAMPRO portable chiller tube cleaner. This product was designed from the ground up with the high volume user in mind. It features quick connect shafts and brushes for faster, easier tool changes and offer chain driven technology for increased performance. Additionally it integrates a sturdy roll cage into it’s design to protect it from the environments of the transport and facilities rooms it is used in.

Please keep Goodway in mind for all your HVAC and facilities maintenance products needs and as a special reward to our loyal blog readers we are offering 10% off product sales valid ONLY by clicking on this link.

Today is the first day of summer – and that means it’s time to crank up your facility’s AC. Is your facility’s cooling system ready?

How-to-HVAC-Cleaning-Checklists-77x300Last year we offered three checklists to help you prepare for the cooling season. It’s time to revisit our checklists before the real summer heat arrives. Give your facility’s cooling system attention now to keep it operating efficiently.

Checklist 1: How to Clean Chiller Tubes

Checklist 2: How To Clean Air Conditioner Coils

Checklist 3: How to Clean Cooling Towers

HVAC, Building Performance: Chiller Performance and Energy Usage

Chillers typically use about 50% of a facility’s electrical energy during the seasons when they’re in use, according to the N.C. Department of Environment and Natural Resources.

OLYMPUS DIGITAL CAMERAPoorly maintained cooling towers reduce the chiller efficiency by 10% to as much as 35%; a dirty coil condenser can reduce efficiency by 5% to 15%, according to the agency.

Efficiency Technologies Inc. estimates that there are over 100,000 chillers in use in the United States, and inefficiencies among them cost industry billions of dollars in energy each year.

HVAC, Building Performance: Cooling Tower Maintenance & Goodway’s Cooling Tower Vacuum

We’ve talked about cooling tower maintenance quite a bit on the Goodway blog. And now that it’s spring and we’re starting to think about air conditioning maintenance, the subject is on our minds once again.

iStock_000022676282SmallIf you look back at past posts, you’ll see that the top two reasons for cooling tower maintenance resonate through them all: energy efficiency/system performance and health.

Often the importance of cooling tower efficiency is a bit overlooked because the focus is on chiller efficiency.

“Chillers use about five times the energy of the cooling tower. Consequently, more attention is paid to the chiller than the cooling tower in most facilities,” Steve Spielmann, Goodway’s Customer Service/Technical Manager, explains in this post about cooling tower maintenance.

Post-Hurricane Sandy Series: Clearing Flood Waters

This week we continue our Post-Hurricane Sandy Series with what you need to know about clearing flood waters.

Our next posts in the series address mold and mildew management, cooling towers and FEMA (Federal Emergency Management Agency) assistance.

Safety is probably the most crucial factor to consider in dealing with flooding. Flood water can contain a host of infectious organisms including E. coli, shigella, salmonella, hepatitis A virus, as well as typhoid, tetanus or paratyphoid agents, according to the Occupational Safety & Health Administration (OSHA).

But it doesn’t stop there because flood waters may also become contaminated by industrial chemicals from flooded hazardous waste sites.

Risk Management When Using Ammonia as a Refrigerant

Ammonia is looking like one of the more plausible solutions for replacing refrigerants that damage the environment including HFCs (hydrofluorocarbons), as we note in our previous post, Ammonia As A Refrigerant: Pros and Cons – Follow Up.

Our 2009 post, Ammonia As a Refrigerant: Pros and Cons, has become one of our most popular blogs, possibly because of the buzz that’s been generated around using ammonia to replace common refrigerants.

While ammonia has been used less in the past because of health hazards as well as its smell, the newer technologies are making ammonia use safer in chiller tubesair conditioner coils and cooling towers.

A Greener Choice: Ammonia as a Refrigerant

Supermarkets are high energy users, with more than half of their energy usage attributed to refrigeration, according to an article in Environmental Protection.

The online publication points to a paper from the Oak Ridge National Laboratory that puts the average supermarket energy usage at 1 million to 1.5 million kWh per year. Compare that to the 11,040 kWh an average home uses per year. High energy usage, particularly with some of the older technologies, leads to more wear and tear on our ozone layer, according to the article.

The EPA’s GreenChill partnership program works with supermarkets and other food retailers to reduce refrigerant emissions by making operational changes, investing in new systems and focusing more intensely on leak prevention. Retailers showing the most improvement in energy efficiency initiatives are recognized yearly by the EPA. The most recent awards ceremony was held in early September.

Newer stores have the upper hand in emissions reductions as they can use newer refrigeration systems. Many of these newer stores offer technologies not available when the GreenChill program originally started.

Ammonia is part of a group of natural refrigerants, similar to propane, carbon dioxide and other gases, that is showing more use throughout the industry in, according to Supermarket News. These gases have little impact on global warming and don’t harm the ozone layer.

While ammonia has been used less in the past because of health hazards as well as its smell, the newer technologies are making ammonia use safer in chiller tubesair conditioner coils and cooling towers. Ammonia is becoming a potential replacement for other refrigerants, such as R-22, which are known to harm the ozone and affect global warming harshly.

Keilly Witman, a representative for the EPA’s GreenChill program, spoke last spring at the Food Marketing Institute Expo about ammonia and other natural refrigerants dominating the food retail industry, according to Air Conditioning, Heating and Refrigeration News.

“In the U.S. supermarket industry, misconceptions of ammonia (R-717) and the codes that govern it, coupled with a lack of knowledge pertaining to the systems, serve as major hurdles that will need to be cleared before ammonia can be accepted as a viable alternative to traditional halocarbon refrigerants,” says Caleb Nelson of CTA Architects speaking at the International Institute of Ammonia Refrigeration’s annual conference in 2012.

In the same speech Nelson explains that ammonia has been used safely and efficiently for years in other industries around the world. The initial cost and training can be substantial, but they’re only temporary. And the issues with ammonia use are no different that the issues faced in using other natural refrigerant technologies.
