Walk-in Freezers Used to Heat Water?
February 1st, 2010 commentsAt U.S. Cooler, we strive to bring more value to our customers. One of the ways we accomplish that is by keeping informed on opportunities to improve your bottom line.
Did you know your walk-in coolers and freezers are potentially capable of doing double-duty? It’s a well kept secret you may wish to consider. Depending upon your existing (or hopefully new, from U.S.Cooler) equipment, you may be able to save thousands of dollars annually by capturing the heat rejected from air-cooled condensing units and using it to pre-heat hot water.

Retrofitting LED Lights Can Pay Off In Your C-store
January 20th, 2010 comments
As a convenience store owner, if there was a change you could make to increase merchandise sales, lower your electric bill, reduce maintenance costs, and be environmentally responsible would you make the change? The opportunity to do just that is here with the advent of LED Retrofit Kits. These kits replace the existent fluorescent lighting on your glass door merchandising walk-in cooler and freezer with 4’, 5’ or 6’ long LED light strips.LED lighting provides a 68 to 85% energy savings over the fluorescent lights typically used in coolers and freezers. LED’s use only 15 watts for a 5’ model and 18 watts for 6’. But if energy savings was the only advantage, adoption of LED’s wouldn’t be near where it is today. The real difference is the attractive quality of the light it gives off. LED’s give your products a beckoning glow and more uniform illumination than fluorescent. You can choose between lights that give off a neutral or slight red or blue hue. Conventional wisdom suggests that the more appealing the product presentation, the more likely a customer is to take notice and purchase it. Read the rest of this entry »
Types of Refrigeration Systems Used in Walk-ins
January 13th, 2010 commentsRefrigeration systems consist of a condensing unit and an evaporation coil. The condensing unit is located outside the walk-in and the evaporator is located inside the walk-in. The compressor compresses gas to a liquid. The liquid is then pumped through the condensing unit coil while a fan blows outside air through the coil. Gas is condensed to a liquid and is then pumped through a small copper pipe into the walk-in to the evaporator coil. There, through the expansion valve located in the evaporator coil the liquid is allowed to expand back into a gas. The expansion of the liquid to a gas causes a rapid chilling of the evaporator coil. Since heat always flows toward cold, inside the walk-in air is blown across the evaporation coil to let the coil absorb heat from inside the walk-in. The gas is then allowed to exit the walk-in through a larger copper pipe to the condensing unit where it is once again compressed and cooled to a liquid state and returned to the evaporator coil inside the walk-in. There the cycle is started over.
The new EISA law requires all new walk-ins be equipped with high efficiency motors to be compliant. These cost a little bit more but save you money in the long run. Some suppliers may try to sell you non EISA compliant refrigeration systems. To be compliant with the law and purchase the best lifetime value always ask for EISA compliant equipment.
1. Remote Systems - Remote systems are the least expensive systems to purchase. They consist of a condensing unit, evaporator unit and misc. parts such as expansion valve, site glass, dryer, pump down solenoid thermostat, and on freezers a timer and drain heater to install the system. They require the use of a licensed refrigeration installer since they are pumped down and charged with refrigerant gas on site. The installer will also charge for any other parts needed for the install such as copper pipe, pipe insulation, connectors, and electrical. They are less expensive systems to buy with the walk-in but may cost more over all depending on what the going hourly rate is with the installer and the cost of the parts he provides. They also provide an advantage by allowing the condensing unit to be located outside the building. There the condensing unit can dump its heat without adding extra heat to the building and air conditioning systems. Read the rest of this entry »
Lighting Efficiency of Incandescent & CFL vs LED
December 30th, 2009 commentsLED lighting is becoming increasingly popular in the gas station c-store industry. This is not only due to the lower energy consumption of the LED lamps, but the new lighting also makes the beverages in the coolers more visually appealing!
OSRAM Opto Semiconductors recently released their findings from a study on the life-cycle assessment (LCA) of LED lamps. Here is a summary of their findings.
LED life-cycle assessment
Light Emitting Diodes are among the most energy-efficient light sources available on the market. LED lamps are already today more than five times more efficient than incandescent lamps and future technical achievements offer additional potential for the coming years.

At present, artificial lighting accounts for around 19% of global electricity consumption – that corresponds to 2.4% of worldwide primary energy consumption. Read the rest of this entry »
Firehouse Renovation on Illinois Stories
December 10th, 2009 commentsCraig Industries / U.S. Cooler’s corporate offices are located in a renovated firehouse in Quincy, Illinois. Engine House No. 4 was originally built in 1898 and housed two horse-drawn fire wagons. It was used by the fire department until 1940 and has subsequently been used for textile manufacturing. In the Fall of 2008, Craig Industries completed a restoration of the building that was faithful to the original design. The interior features modern amenities but still has a nostalgic feel with the original brick walls and wooden supports intact.
Engine House No. 4 will be featured on the PBS program Illinois Stories at 6:30pm, December 10th (WSEC – Jacksonville/Springfield, WQEC – Quincy, QMEC – Macomb).
Illinois Stories: From the river heritage of Quincy and Hannibal, to the bounty of the richest farmland on earth, Mark McDonald hosts this Emmy award winning series about the people and places of central and western Illinois. PBS
R-22 Phase out January 1st, 2010
December 1st, 2009 commentsJanuary 1st is just around the corner. Now is the time to start preparing for the R-22 refrigeration phase out. Starting in 2010, manufacturers can only produce R-22 refrigerant to service existing equipment. All newly manufactured units will use an alternate refrigerant.
Important Things to know about the R-22 Phase Out
The phase out of the ubiquitous R22 refrigerant gas changes many things for the consumer. If you need to know more about the phase-out, you should read the following pointers.
1) In the United States, there are regulatory bodies like the EPA that have laid down strict guidelines with regards to the regulation and maintenance of refrigerant leaks. The Montreal protocol and the Kyoto protocols have been initiated on an international level to regulate similar parameters. These protocols are being put into place to regulate the repair of refrigerant leaks and the disposal of older machines that use such refrigerants. Read the rest of this entry »
Food Safety Reform Bill Passes U.S. Senate Panel
November 24th, 2009 commentsWASHINGTON (Reuters) – A U.S. Senate committee voted unanimously on Wednesday to increase government oversight of food safety but the first significant overhaul in 50 years may not happen until 2010.
Pressure to overhaul the food safety system has grown following several high-profile outbreaks involving lettuce, peppers, peanuts and spinach since 2006 that have sickened thousands and killed several.
However, the full Senate probably won’t vote on the bill until 2010 as Congress is currently mired in debate about overhauling the U.S. healthcare system, said Tom Harkin, chairman of the Senate Health, Education, Labor and Pensions Committee.
“I really, honestly, I just don’t see how we’ll get to it before Christmas,” Harkin said of the food safety bill.
The Senate bill would expand U.S. Food and Drug Administration (FDA) oversight of the food supply and shift its focus toward preventing, rather than reacting, to foodborne outbreaks. FDA would have the power to order recalls, increase inspection rates and require all facilities to have a food safety plan. Read the rest of this entry »
How to Replace Walk-in Refrigerator Door Gaskets
November 6th, 2009 commentsThe following article is courtesy of Tundra Specialties.
The rubber door gasket on the inside edge of the doors of all your refrigeration equipment is very important. It prevents cold air from escaping, which means the unit will stay colder longer and use less energy. Old gaskets wear out and lose their seal. Even worse, older gaskets can pose a food safety risk because they begin to collect grime and food bits and become a breeding ground for bacteria.
Luckily, it’s easy to replace door gaskets! There are several different styles of gaskets. To insure you get the proper gasket, gather the following information:
1. Dimension of gasket – Measure from outside corner to outside corner for both height and width.
2. Manufacturer – Get the manufacturer’s name and the model and serial number of the piece of equipment (the serial number may not be needed).
3. Style – Check to see if the gasket is magnetic or non-magnetic(compression). Almost all newer refrigeration equipment will have a magnetic gasket. A magnetic gasket will be hard and square at the point where it contacts the inside frame of the unit. Magnetic gaskets will also snap shut when you hold the door less than an inch from the frame because the magnet attracts to the metal.
Magnetic door gaskets are the most common.Compression gaskets usually need a door latch to hold them tight in place to get a good seal. These gaskets are soft and compress easily at the point where they contact the inside frame of the unit.
A compression style door gasket.Door gaskets are also categorized by how they attach to the door. There are 3 ways a door gasket mounts on a door: snap in (or dart), push in, and screw in.

October 21st, 2009 commentsWASHINGTON — The U.S. Department of Energy (DOE) has announced three new steps to strengthen its ability to enforce energy efficiency standards. DOE has formed a new enforcement team within the Office of the General Counsel; established a program to randomly review manufacturers’ compliance with DOE certification requirements; and is publishing guidance that provides further details about DOE’s energy efficiency enforcement regulations.
In its new guidance, DOE confirms that under existing regulations, it can take enforcement action and assess civil penalties if a manufacturer fails to properly certify a covered product and retain records. Specifically, the agency clarifies that any failure to certify covered products according to DOE’s rules violates the Energy Policy Conservation Act of 1975 and DOE regulations. DOE will randomly select previously filed certification reports for review, request certification records as needed, and hold manufacturers accountable for failing to certify covered products according to DOE rules.
