Quaternity™ by Daikin Gets New SEER Rating
Daikin AC is pleased to announce that Quaternity™ (model number RXG09HVJU and FTXG09HVJU) has been rerated to achieve a SEER rating of 26.1 from the Air Conditioning, Heating and Refrigeration Institute (AHRI).

The Quaternity system, initially introduced in 2009, has been rerated to better reflect the actual performance of the system. The Quaternity system comprising 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 respectively of 26.1, 24.2 and 21.0.

Quaternity can dehumidify in two different ways. In "Quaternity dry mode," the system lowers humidity without affecting the room temperature by mixing dry cool air with warm air to produce comfortable dry air. If the indoor temperature becomes too high,

Quaternity's "dry cooling" operation cools and dehumidifies to a relative humidity setting. Users can set higher set-point temperatures, but with a 50% humidity set-point realizing significant energy savings yet still providing a very comfortable environment, sources say.

Caleffi Announces New Manifold Mixing Stations
Caleffi's 171 and 172 series manifold mixing stations regulate the system's fluid temperature and are specially designed for use in manifold-based hydronic distribution systems.

The 171 series motorized manifold mixing station incorporates a modulating three-point floating actuator to regulate the temperature of the fluid sent to the system flow manifold according to the actual thermal load, in response to a separately-sourced outdoor reset controller. The 172 series thermostatic manifold mixing station maintains the flow temperature at a constant set value for use in low temperature systems such as floor radiant panels. Both series come complete with a motorized three-way mixing valve (171 Series) or thermostatic three-way mixing valve with built-in temperature sensor (172 series), three-speed pump, supply temperature and pressure gage, return temperature gage, purge valve, primary circuit shut-off valves, 3 to 13 supply manifolds equipped with flow meters and balancing valves, and automatic air vent with hygroscopic cap and drain cock.

A removable primary circuit hydraulic separator with check valve is also supplied. The hydraulic separator is essential when there is a primary circuit circulation pump and when radiator circuits or fan coils are controlled by thermostatic or thermo-electric valves.

The 171 and 172 series stations can also be ordered with optional TWISTOP™ thermo-electric zone actuators.
