Evaporator Fan Controller For Refrigeration

Conserve Energy By Controlling Evaporator Fan Motor Speed On Commercial Refrigeration Walk In Cooler & Walk In Freezer Evaporator Coils

Energy Saving Evaporator Fan Controller For Walk In Coolers & Freezers
Functional Devices Evaporator Fan Controller Model EFC4045T

Save money and electrical consumption on your Walk In Coolers & Walk In Freezers with the Refrigeration Evaporator Fan Controller by Functional Devices Inc. This is crucial, especially when you consider Commercial Refrigeration accounts for at least 20% of electrical consumption worldwide!

The process is simple: When the supply air from the Evaporator Coil is equal to return air, fan speed is decreased. When the supply air from the evaporator coil is colder than return air, fan speed is increased. The major benefits to installing this Controller are drastically reduced energy consumption and less heat generated into the conditioned space. This results in longer refrigeration off cycles & increased energy savings. Most Evaporator Fan Motors run 24 hours a day, so optimizing operation can achieve signifigant savings. The controller comes in two models: The EFC4045T can control both Shaded Pole Motors & ECM Motors; Model EFCECM1T is designed for use with ECM Motors only.

I’ve compiled a short list of the specifications & features of the Evaporator Fan Controller. For more information including a calculation of energy savings, money savings calculator, installation instructions  & data sheet downloads see the manufacturer’s website.

  • Simple Installation
  • For use With Walk In Coolers & Freezers
  • When Compressor Is Off Evaporator Fan Speed Is Automatically Reduced
  • Compatible with 120, 208 & 240 Volt Circuits
  • Compatible With ECM Motors & Shaded Pole Motors

Know When To Replace Your Commercial Refrigerator Or Compressor

When it comes to repairs, think of your commercial refrigerator like you would your car. Imagine the compressor in a cooler is like an engine in a vehicle. If the compressor goes bad and is replaced you get a new compressor, not a whole new cooler. The same way the garage doesn’t tell you to get a new car just because you need a bit of engine work. In other words, all the other components including coils, fans, controls, piping, and  gaskets (door seals) are still old. This is similar to an engine in a car going bad and being replaced. You end up with a new engine in an old car. There are a couple of key factors to consider when trying to decide whether or not to do a major repair on a piece of refrigeration equipment. Here are a few things to ponder before pulling the trigger on an expensive repair.

1. How old is the cooler? If older than 10 years it is advisable to price out a new one.

2. What kind of refrigerant is used in the cooler? If the answer is R12, R502, or R22, consider pricing out a new cooler. R12 and R502 have been banned by the EPA for years and R22 is currently being phased out by the EPA.

3. What is the overall condition of the cooler? Check door seals, hinges, floor in cooler, coils, and fans. If everything looks like it’s falling apart, it may be time to price out a new cooler.

We are happy to perform repairs for customers, but don’t want to see them throwing good money after bad.

Commercial Refrigerator Condensing Unit

Last week a customer in Chicago had a large walk-in freezer compressor go bad. The condensing unit that the compressor was part of was around 18 years old. The system was set up to run on R502 gas which is now obsolete, since it has been banned by the EPA. There were two options for customer: 1. Get same compressor and convert the  system to a newer style gas called R404A,  or 2. Replace the entire condensing unit including compressor, condenser coil, fans, controls, and enclosure with a new unit set up for R404 gas. The new unit is far more efficient than the old condensing unit.

Our customer ended up going with option #2 and we installed a new R404A condensing unit for their freezer. That was a good choice.

If your commercial refrigerator is set up to run on obsolete gas it’s time to replace it when any major repair comes up. The unit is most likely very energy inefficient.

Summer Sizzle Elicits One Word: Maintenance!

 

After this past week’s heat brief, but brutal, heat wave we just cannot stress enough the importance of maintaining your commercial refrigeration equipment. While we love the business, we hate to see you in a bind!

Even one of our friends learned the hard way at home in Lake County. “Who needs to check the air conditioning?”  Our friend has since changed her tune when the a/c unit refused to turn on as the temperature inside the house was soaring to 89 degrees!  The guilty will remain nameless to shelter her from further shame at the lack of preventative maintenance.

She survived, but you don’t want the same thing to happen to your commerical refrigeration equipment!

You NEED your ice machine!

Commercial Refrigeration Going “Green” – R744 & Retrofit Viable Options Over R22

Refrigeration Goes Green

Even in the recesses of your local grocery store or corner pub, the initiative to provide cleaner air and a more stable environment is alive and well. We don’t often think about grocery stores, restaurants, bars, and other businesses as being Green, but in reality these types of businesses are being charged by The Montreal Protocol to clean up their act completely by 2030. Commercial refrigeration currently relies heavily on R22 as a refrigerant; however, this kind of refrigerant is known to deplete the ozone layer.

With the worldwide phase-out of ozone depleting HCFCs (hydrochlorofluorocarbons) including R-22, we need to start thinking of other alternatives, especially Green alternatives.

Under the terms of the Montreal Protocol, the U.S. agreed to meet certain obligations by specific dates:

  • January 1, 2004: U.S. is required to reduce its consumption of HCFCs by 35% below U.S. baseline cap.
  • January 1, 2010: U.S. is required to reduce its consumption of HCFCs by 75% below U.S. baseline cap.
  • January 1, 2015: U.S. is required to reduce its consumption of HCFCs by 90% below U.S. baseline cap.
  • January 1, 2020: U.S. is required to reduce its consumption of HCFCs by 99.5% below U.S. baseline cap.
  • January 1, 2030 U.S. is required to reduce its consumption by 100% below U.S. baseline cap.

What this means is that within the next four years the U.S. needs to be 90% below its previously allowed usage cap of R22. R22 has been the most commonly used refrigerant for decades. Both commercial and residential consumers need to find alternatives to R22 for their cooling needs.

R744: A Natural Alternative

One such option is provided by Linde, a leading supplier of refrigerants for over 40 years. Linde has operations in 40 countries on five continents. They are currently offering a more eco-friendly option to R22. A carbon dioxide called R744 is a refrigerant grade CO2. R744 can be used for a variety of refrigeration needs, such as, air conditioning, commercial refrigeration, process chilling, or heat extraction. Linde believes R722 will help meet the world-wide environmental regulations.

Carbon dioxide has been used as a refrigerant since the 19th century. When fluorocarbons were introduced the 1930s, CO2 fell out of favor, and was all but cast aside by the 1950s. Today, with its low environmental impact, CO2 is now seeing a resurgence in popularity from refrigeration system designers and users.

Advantages of R744

According to Linde, R744 is now regaining popularity due to a number of advantages:

  • Low toxicity
  • Non-flammability
  • Zero ozone depletion potential
  • Very low global warming potential (GWP=1)
  • Excellent thermodynamic properties and low energy requirement

RETROFIT: Another Option

Another option is to start thinking retrofit. There are numerous commercial refrigeration systems that still use R22 gas. Although it is currently still possible to use R22, because it is being phased out, the cost is going up drastically. We recommend replacing the compressor unit and TXV expansion valve on coolers or freezers and then retrofitting to a new style of gas. This is especially valuable when an old R22 system compressor fails. The failure of the system becomes an opportunity to retrofit it to run on a gas that produces less ozone depletion during the repair process.

Honeywell Has a Retrofit Option for Current R22 Users

“Supermarket customers are looking for an R-22 replacement that can work in both retrofits and new equipment installations,” said Paul Sanders, Commercial Director for Honeywell Fluorine Products in Europe, Middle East, Africa and India. Genetron Performax LT offers a significant reduction in total greenhouse gas emission with the added benefit of lower operating costs.” Genetron Performax LT is an A1- rated refrigerant, indicating it has low toxicity and is non flammable. Honeywell advises against retrofitting too soon. The company suggests considering all aspects including the energy consumption of the refrigeration equipment throughout its remaining life. Retrofitting could prove to be more harmful to the environment when you add global warming potential into the equation. Sound service and maintenance schedules are vital to keeping any cooling system healthy and environmentally sound.

Whichever option you choose to use should be a carefully considered decision.  Give us a call at Northeast Cooling to discuss what refrigeration option is best for you and your business. We strive to meet your needs in the Greenest way possible.
