Tyco Thermal Controls showcased the Raychem XL-Trace heating cable systems, designed to freeze-protect fire suppression systems. The FreezeAlarm freeze-protection device from Control Products featured wireless sensing technology that allows up to 10 sensors to monitor different zones. When temperature falls below setpoint, the unit can call up to three phone numbers. Rittling’s vertical water source heat pumps use R-410A refrigerant and provide heating/cooling to single and multiple-zoned spaces. The heat pumps are certified to ISO13256-1 for water loop, groundwater, and ground loop applications. Enertech Manufacturing offered the GeoComfort Compass multiposition packaged water-to-air geothermal heat pump. It is shipped as left-hand return/top discharge, but can be field-converted to right-hand return and/or bottom discharge. The EN Series from Dectron is a modularly constructed and energy-efficient precision air-conditioning line for data and electrical equipment centers. Bry-Air’s EcoDry desiccant dehumidifiers with BrySmart control technology reduce energy use up to 45%. BrySmart can also be retrofitted to existing systems.

that enables users to store and share digital assets such as job site videos and photos, job reports and maintenance records.

EnviroFlo HVAC pumps from Patterson Pump feature an end-suction design that minimizes energy consumption and increases efficiency. Control, From Page 10 son Climate Technologies, Rheem, and Watsco, as well as 16 other contributing and adopter members. Climatetalk Alliance recognizes that multiple protocols will exist in the home. ClimateTalk is an open communications model, designed to be simple to use and low cost while providing advanced control and diagnostic capabilities for residential applications. It defines a standard set of application-level messages that makes communications among energy appliances possible. Auto configuration is a key to success in this part of the industry. By being one company in the Alliance, a member doesn’t need to make all of the HVAC and grid products that homeowners need. “The Alliance sustains the life of the product. The value of the alliance is that the protocol is developed to protect my

intellectual property,” said Kelvin Kleman, engineering manager, electronics and controls at Rheem. Kleman said that from a system perspective an alliance “helps the contractor to access the fault history of the equipment, allowing them to do their job more efficiently.” “We need to grow as an industry. There’s lots of opportunities,” said Kleman. International, From Page 12 Another company exhibiting its wares was Shanghai Moons’ Electric of Shanghai. General manager Roger Hsiao, P.E.

I have not found anyone yet,” (as of the second morning of the Expo) “but it’s a big Show, and I am sure there is time.” It appears that with the influx of international exhibitors, AHR Expo will only get bigger in the future. Also, it may only be a matter of time before some of these international companies become players in the U.S. HVAC&R marketplace.
