Daikin AC Introduces Quaternity™
Daikin AC (Americas) introduces the QuaternityTM described as North America's first inverter split system heat pump capable of dehumidifying room air to a user defined relative humidity (RH%) set point and air cleaning functions.
Daikin's Quaternity system, comprised of indoor unit (FTXG) and outdoor unit (RXG), is available in 3 sizes with nominal cooling capacities of 9,000, 12,000 and 15,000 BTU/hr, with SEER levels of 22, 22 and 21 respectively and EER levels of 15.8, 14 and 12.9 respectively.
During the summer, a high degree of ambient air humidity, even at moderate temperatures, can make a room feel hot and stuffy. Daikin sources say, Quaternity reduces indoor humidity without affecting the room temperature. It does this by mixing dry cool air with warm air to produce comfortable dry air (essentially reheating dehumidifying). This feature prevents overcooling. daikinac.com.

Detector Electronics Corporation (Det-Tronics) introduces an NTMOS hydrogen sulfide (H2S) gas sensor that detects low H2S gas concentrations in five seconds or less while tolerating harsh environments that experience extreme temperature and/or humidity conditions.
COMFORTECH PRODUCT SHOWCASE AWARD
Third-party tested to ISA-92.0.01, the NTMOS H2S gas sensor detects hydrogen sulfide in conditions that harm electrochemical and standard MOS sensors. The sensor is packaged in a rugged housing, protected by a sintered stainless steel flame arrestor, and can be installed in Class I, Division 1 locations. The NTMOS gas sensor can be installed as a stand-alone sensor or combined with a display for local indication.
Mr. Slim® M-Series Offers Larger Capacity
At HVAC Comfortech 2008, 15 products were recognized as Product Showcase Award winners.

Mitsubishi Electric HVAC Advanced Products Division has introduced the Mr. Slim® M-Series D30/36NA, available in cooling only and heat pump systems.
Hydro-Delta Corporation Introduces Mega-Tek Heat Pump
The D30/36NA line is available in the MSY/MUY cooling only and MSZ/MUZ heat pump systems. The heat pump systems feature the Mitsubishi Electric hot-start technology, which provides warmth from the very beginning of system operation. As the coil is warmed the fan increases in speed to deliver the precise amount of warm air to the indoor space. The new MSY/MSZ indoor units use a multi-part filter system to remove contaminants such as dust, pollen and other particles that can cause allergic reactions from the air as it circulates.
The HydroHeat Mega-Tek TS Quadro-Therm heat pump provides space heating, air conditioning and hot water heating in one compact appliance.
Featuring TS compressor technology, a variable speed ECM blower motor, patented dual domestic water heating condensers, on demand plus desuperheating, and a microprocessor controller, the TS Quadro-Therm offers the ultimate in performance, comfort and savings.
The TS Quadro-Therm is suited for residential installations.
