Company: Bally Refrigerated Boxes
Headquarters: Morehead, N.C.
Newest feature: SmartVap II controller
Supplier statement: Bally Refrigerated Boxes makes defrosting simpler and smarter with the new SmartVap II controller, introduced last spring. The controller addresses a major installation challenge: the addition of control wiring between condensing units and evaporators. SmartVap's two pipes and two wires eliminate wiring back to the condensing unit, and the unit is factory preset to suit most applications. Once installed SmartVap electronically controls box temperature, defrost initiation, defrost termination and fan delay. In addition, Bally says it uses energy-efficient HFC-245fa blowing agent to foam the panels in its walk-in coolers and freezers. Bally manufactures custom lengths and widths as well as standard modular units.
Company: Emerson Climate Technologies
Headquarters: Sidney, Ohio
Note: Emerson offers a Copeland Scroll compressor for walk-in coolers and freezers.
Supplier statement: Walk-ins require constant opening and closing, which translates into a recipe for high energy costs. Opting to outfit your walk-in with a Copeland Scroll compressor allows you to take advantage of the technology's inherent ability to maintain more consistent temperature levels and use less energy. The Scroll compressor trades a piston-and-cylinder design for continuously pressurized refrigerant, which typically results in more even refrigerant flow, even temperature and superior efficiency. Thus, says Emerson, the Scroll compressor saves energy and also impacts your maintenance costs due to the durability of the technology and its ability to handle the toughest applications.
Company: Harford Duracool/Manitowoc
Headquarters: Aberdeen, Md.
Supplier statement: All custom walk-ins from Harford come equipped with standard 4"-thick non-CFC polyurethane-insulated wall panels. For units installed outside, a membrane roof cap offers weather protection, and a sloped roof keep rain away from your building. Harford's Super Door construction offers smooth, cam-action hinges and a flush fit. Meanwhile, a freezer defrost time clock is mounted inside the weather housing and set to defrost four times a day. All units are shipped preassembled on a Harford truck, and a drain line from each evaporator is completely factory installed and trapped to the exterior of the walk-in.
Company: Hussmann Corp.
Headquarters: Bridgeton, Mo.
Newest feature: Door Anti-Sweat Heater
Supplier statement: Many anti-sweat heaters in doors operate 100% of the time, regardless of conditions. Hussmann's DASH control ensures optimal energy savings by turning the heat on only when needed and turning it off when not needed. Further, many anti-sweat heaters have externally mounted sensors on the doors. Hussmann's DASH control is integrated into the door-frame assembly and is invisible to the consumer. Finally, many anti-sweat heaters must be installed in the field. Hussmann's DASH control is factory-installed in the door-frame assembly, and the exact location and position of the sensor required for optimal performance is set at the factory.
Headquarters: North Parsons, Tenn.
Newest feature: HFC-245fa insulation
Supplier statement: Kolpak has converted to "green" foam for panel insulation in its entire walk-in refrigeration line. Kolpak builds all panels using the water-based, zero-ozone-depleting HFC-245fa insulation blowing compound, which eliminates the harmful impact of other foaming agents and processes. In addition, HFC-245fa foam can offer higher energy efficiency than comparable insulating foam. Kolpak walk-ins feature a host of other energy-saving features, including Super Door construction, door sweep gaskets, Posi-Loc panels and adjustable door hinges for airtight fit, and reduced compressor run times. Green-friendly R-404A refrigeration systems are also available as an option on all Kolpak units.
Company: Kool Star/Standex
Headquarters: Long Beach, Calif.
Newest feature: Klear Sight Door
Supplier statement: Kool Star says the Klear Sight Door provides energy savings, increased efficiencies and reduced product loss while providing an aesthetic advantage. The Klear Sight Door allows you to view product and inventory before entering the walk-in, encourages staff to keep the walk-in clean and organized, offers an open and non-claustrophobic environment, provides lighting into the walk-in if lights are turned off, and gives management the ability to monitor and decrease product theft and tampering. The Klear Sight Door was designed as an alternate to a full Plexiglass or acrylic door and meets federal energy requirements.
Company: Leer Mfg.
Headquarters: New Lisbon, Wis.
Supplier statement: Leer says its walk-in coolers and freezers feature 4" foamed-in-place panel structures that exceed the requirements of the 2007 Energy Independence and Security Act. All Leer walk-ins incorporate a 12-ga. all-welded steel frame foamed into the door panel for structure and rigidity. Leer corners are two-piece panels that fit together to form a perfect 90� angle for ease of installation. Leer's standard floor is 16-ga. stainless steel, which is strong, resistant to staining and easy to clean. Options include stucco or smooth-panel finishes; prepainted steel, aluminum or stainless steel panel surfaces; and preassembled remote and self-contained refrigeration.
Headquarters: New Albany, Miss.
Newest feature: Master-Controller defrost system
Supplier statement: The Master-Controller process uses less energy than electric defrost heaters, says Master-Bilt, resulting in an 80% reduction in defrost energy usage. This savings, coupled with that from the demand defrost, dramatically reduces electrical bills. While other reverse cycle methods exist, Master-Bilt says the Master-Controller is unique because it's controlled by the electric expansion valve found within the system. Some other systems rely on mechanical components, such as check valves and extra thermostatic expansion valves, to control the reverse cycle valve. This patented system is an example of Master-Bilt's ability to provide the technology and innovations demanded by today's increasingly energy-efficient industry.
Headquarters: Hudson, Wis.
Newest feature: Alarm and light management system
Supplier statement: Nor-Lake's NL708 alarm/light management system was designed to save energy and protect inventory by automatically turning off lights as well as providing an alert when a door has not closed properly. Options available with this system are a door switch that will automatically turn on lights when the door is open, an alarm that will sound when the door has been left open, a motion sensor that will turn on lights when the walk-in is occupied, and a phone dialer that will notify pre-determined phone numbers when the high- or low-temperature limits have been reached.
