ATLANTA, GA – At a Tuesday morning press breakfast, Danfoss introduced several new products, including a new series of wireless thermostats.
Building on its TP 75 models introduced last year, the new models use wireless communication from the thermostat location to a receiver module that can be up to 30 yards away. According to Danfoss representative Mike Taala, the new wireless thermostats can solve the problems of inconvenience and high labor costs where cabling to the thermostat would require damaging the finish or structure of a building.
According to Taala, each thermostat has a unique identity code as part of the information packet decoded by the receiver.
“Unlike many other systems on the market that use matched thermostats and receiver pairs, the Danfoss system has technology that allows a receiver to learn the unique identity code of its thermostats during installation. After commissioning, the receiver responds only to its own unique thermostat,” said Taala. “If it is ever necessary to replace the thermostat or receiver, the new component can be taught to communicate to the existing unit.”
Receiving units are available in one-, two-, or three-zone versions, and can be used with any two versions of the company’s wireless thermostats.
Danfoss also unveiled its new 6000 series of electronic, programmable, 5/2-day heat/cool thermostats. According to Taala, there are models for heating or cooling applications such as 2-pipe non-changeover systems, and also heat/cool models for use in 2-pipe changeover systems and in 4-pipe non-changeover systems.
All models have a fan output; selected models provide manual 3-speed fan selections.
SCROLL COMPRESSORSThe company also introduced its 20- and 25-ton PerformerÒ scroll compressors. With today’s new models, the Performer range of capacities is from 7 to 25 tons, with tandem, trio, and quadro assemblies extending up to 100 tons. According to Danfoss representative Jeff Weber, the multiple compressor circuit capability of the Performer helps standardize construction, simplify manufacturing, reduces lead times, and lower costs.
“The Performer line is used in a wide variety of applications, including liquid chillers, split air-conditioning systems, rooftop units, and close control air conditioning. These compressors have EER’s among the highest on the market, low sound and vibration levels, and a large refrigerant charge limit,” said Weber.
