Proposed Rulemaking for Walk-in Coolers and Freezers

Proposed Rulemaking for Walk-in Coolers and Freezers

Since EISA was passed January 1, 2009, the U.S. Department of Energy (DOE) has been working to mandate a standardized energy efficiency test for walk-in coolers and freezers.  The first step was taken with an informal meeting on February 4, 2009 to discuss comments and suggestions from industry professionals on determining a testing procedure. After nearly a year’s worth of research, DOE has published their proposed testing procedure for walk-in coolers and freezers. A follow-up meeting was scheduled to discuss these proposed rulings, but due to winter weather the meeting was cancelled and has not been rescheduled at this time.

In accordance with section 312 of the Energy Independence and Security Act (EISA), DOE published a Notice of Proposed Rulemaking (NOPR) for the test procedure on walk-in coolers and freezers. The NOPR is the first published document for the test procedure rulemaking process for walk-ins. DOE proposes the procedures explained in the NOPR be used to test walk-in equipment. Once performance standards are accepted, manufacturers will be required to use the accepted test to determine compliance and for all representations regarding the energy use of the product.

DOE proposes to adopt a test procedure that contains two separate testing methods; one for the insulated box and the other for the refrigeration equipment. Each of the two components, the insulated box and the refrigeration system, will be tested separately. The manufacturer will be responsible for testing their product respectively and must provide compliance with all testing standards.  Read the rest of this entry »

New! Copeland Scroll Outdoor Condensing Unit

Copeland now carries outdoor condensing units for the food service industry. There new light weight, slim shaped units are available in medium and low temperatures ranging from 2 – 6 horsepower.

Copeland Scroll Outdoor Condensing Units are perfectly suited for walk-in cooler and freezer applications. All units integrate the many benefits of the Copeland Scroll compressor technology, fan speed control and Copeland Performance Alert™ diagnostic controls, and are available in 208/230 single-phase and 208/230 three-phase voltage applications.

Scroll compressors offer the highest energy efficiency levels to lower energy bills. With integrated controls that optimize fan motor speed to maximize the heat transfer through over-sized condenser coils, additional energy savings are achieved. The average energy savings for end-users is $350 per year for a 3HP medium temperature unit, however this number could be greater depending on the application.

Walk-in Freezers Used to Heat Water?

At 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.

Types of Refrigeration Systems Used in Walk-ins

Refrigeration 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 »

Firehouse Renovation on Illinois Stories

Craig 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

January 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.

How to Replace Walk-in Refrigerator Door Gaskets

The 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.

Walk-in Saves Lives

On Wednesday, August 19th, a tornado ripped through the village of Williamsville, IL leaving parts of the town a disaster with many home’s lost. One particular building that was in the direct path of the storm was a Casey’s General Store. When the storm rolled in, there were 9 employees and customers in the store. The entire front wall of the building was blown out leaving no shelter for the group in the store. Immediately they took cover in the walk-in cooler where they safely remained until the storm ended. After the storm, the only structure of the building still intact and left unharmed was the walk-in combination unit. Check with your local emergency center for the emergency plan that best fits your location.

U.S. Cooler is now leasing walk-ins

Buying a walk-in cooler or freezer is a large expense for any business and not all companies have the cash flow available to purchase a walk-in outright. U.S. Cooler has another option for our customers. Leasing.

By leasing your walk-in, you avoid having to come up with the complete purchase price necessary to buy it outright. Instead, with leasing, the cost is spread out comfortably over a fixed period of time, and only a small initial down payment is required. Leasing removes the need for equity financing. It also allows you to acquire and use an asset without having to make a substantial down payment. Thus, minimizing the affect on your cash flow and working capital.

U.S. Cooler has partnered with Advantage Leasing to provide our customers with a financing program for their walk-in equipment. For more information on the program visit the leasing program page on our website or contact Advantage Leasing for details.
