Water manager
For water reclamation, the AX-CTI Water Management Center processes and directs rainwater, graywater, groundwater, and condensate for use in non-potable applications, such as cooling towers, toilets, and irrigation. The management center is BACnet compatible to enable easy integration with building-management systems.

Humidity/temperature sensors
Using a 418-MHz transmitter, Series WHP wireless humidity/temperature sensors can transmit data up to 100 ft without the use of a repeater. When coupled with a receiver and output module, the sensors can output voltage, current, or resistance values for humidity and temperature.

Building-information modeling
Building-information modeling (BIM) is now available on Siemens' most commonly used HVAC products, making field components more easily obtainable during the design phase. BIM files can be downloaded from Autodesk Seek, www.seek.autodesk.com, an online source for product specifications and design files, or the Siemens Website at www.usa.siemens.com/hvac.

Control valves
With a built-in pressure differential controller maintaining constant pressure, AB-QM pressure-independent control valves have 100-percent authority at all load conditions, eliminating overflows and underflows resulting from pressure fluctuations in a system. The valves are available with a range of actuators for all control strategies: on/off, three-point floating, and modulating.

End-suction pumps
The line of CR-H horizontal multi-stage end-suction pumps now includes additional American National Standards Institute (ANSI) sized pumps in ductile-iron construction. For flows of up to 635 gpm, the pumps offer an ANSI dimensional plug-and-play solution that will fit into existing pump and piping footprints, offering optimized duty points to maximize pump efficiency and minimize internal wear.

Energy-management system
The USE Controller energy-management system (EMS) is designed to provide a savings of 10 to 35 percent on oil and gas usage, as well as payback in less than two years. Fully integrated with the USE Manager online building-management system, the EMS is digital and wireless. Additionally, the EMS integrates outdoor and indoor temperatures with a proprietary mathematical function to help boilers run more efficiently and cycle off and on when specific temperature presets are achieved.

Fan-coil units
Enviro-Tec floor-mounted fan-coil units include wireless networking capabilities that enable communication with a building-automation system. A programmable thermostat that uses a clock for unit setback or a passive infrared (PIR) sensor that senses occupancy to determine setback helps manage energy consumption. The units consume 30- to 50-percent less energy than comparably sized units.

Portable air conditioners
A redesigned portable air conditioner that delivers 5 tons (60,000 Btuh) of cooling capacity, Strategic Air Center (SAC) Model 6021 features a high-tech design in a compact package that measures 24-in. wide by 52-in. long by 57.5-in. high. It has a hyper-twin-direct (HTD) drive, which uses less space than belt drives, resulting in a smaller footprint.
