CHICAGO—Master-Bilt, manufacturer of a full line of premier commercial refrigeration systems for 70 years, will display its energy-saving equipment and technology at the National Restaurant Association Restaurant, Hotel-Motel Show May 17-20, 2008 at McCormick Place in Chicago, booth No. 7213.
“Master-Bilt recognizes the growing trend and demand for ‘green’ equipment solutions,” says Bill Huffman, vice president of sales and marketing for Master-Bilt. “We are always looking for ways to provide products that will help our customers reap the environmental and economical benefits of energy efficient equipment.”
Some of the energy efficient equipment and technologies on display at the NRA show include:
• Master-Bilt’s Master Controller with patented Reverse Cycle Defrost for walk-in refrigeration systems offers up to 27 percent in energy savings for the user, due to its innovative technology. Reverse Cycle Defrost offers up to an 80 percent decrease in defrost energy usage, as well as significant reductions in defrost time. The reverse cycle process involves a valve that reverses the flow of high temperature refrigerant through the evaporator coil, heating along its entire length and eliminating frost buildup. A highly efficient electric expansion valve, an integrated part of the optional Master Controller system, eliminates the need to maintain a high head pressure, yielding higher capacity with less energy input.
• Master-Bilt’s ASM-115 “Greenheat” anti-sweat module for glass door walk-in units alleviates condensation build-up on glass doors and frames, for continuous product visibility, while also significantly reducing energy costs. Heaters on the Greenheat device are only energized as needed when the door surface temperature is lower than the dew point. An exterior mounted door frame sensor modulates the door and frame heaters as needed. The sensor is designed to automatically shut off glass and frame door heaters when door heat is unnecessary. Greenheat meets California energy standards.
• The MBWA-1 walk-in alarm system is designed to help eliminate energy waste on walk-in units. With one terminal dedicated to a door-open alarm, the second terminal option is either a light management system or a panic alarm. If a door is left open, the unit has both an audible and visual alarm for warning users. The light management system option features a timer, adjustable from one to 255 minutes, that shuts off the lights automatically, so as not to waste energy.
System Extends Life of Cooling Equipment
• MRS series modular multi-compressor refrigeration systems are designed to save energy and reduce in-store heat and noise in quick serve restaurants, convenience stores, hotels and other foodservice operations. By remoting all refrigeration systems, including those in reach-ins, walk-ins and ice machines, to a single MRS system, business owners can remove the heat produced by multiple refrigeration systems from their kitchen or store and reduce their air conditioning load. This outside system, typically roof-mounted, also reduces noise level and extends the life of equipment.
• Numerous cabinets and glass door walk-in freezers feature electronic (T8) lighting with electronic ballasts which use less electricity than electromagnetic ballasts. Electronic lamps and ballasts run at cooler temperatures, reducing heat buildup in the refrigerated space.
• Five- and six-inch thick panels are an option on Master-Bilt’s walk-in coolers and freezers to produce a higher R-factor (resistance to heat flow). Master-Bilt is one of the only manufacturers capable of supplying six-inch-thick ceiling panels up to 23 feet long with no additional support needed. Five- or six-inch panels are required to meet California Energy Code.
• Permanent Split Capacitor (PSC) fan motors are an option on Master-Bilt’s single-phase walk-in unit coolers and come standard on their condensing units. PSC motors are more efficient, requiring a low amount of torque and current to start, and run lower temperatures, reducing heat load to refrigerated space and allowing the compressor to run less frequently.
