Commercial QV Series Heat Pumps – Bosch Thermotechnology
Bosch Thermotechnology introduced its ultra-quiet heat pumps, the QV Series, for commercial spaces in multiple sizes and both horizontal and vertical configurations.
The commercial-grade QV Series, a Florida Heat Pump (FHP) geothermal system, offers comprehensive sound performance. In addition to the lower sound levels, the QV Series also delivers a compact cabinet, making it ideal to fit into small spaces in commercial buildings.
The QV Series includes a constant airflow ECM DEC Star® blower that produces the same cfm as the Bosch LV model but at a lower rpm, resulting in decreased power consumption and sound. The QV heat pump also features Bosch’s patented compressor encapsulation, which includes high-density, mass-loaded vinyl insulation material wrapped around the blower and also installed in the lower compartment, dampening the sound it emits.

ARUX Airstage VRF Multi-Position Air-Handling Unit – Fujitsu General America Inc.
Fujitsu General America Inc. introduced its Airstage VRF multi-position air-handling unit (ARUX), featuring seven models ranging from 1-5 ton. It is designed to meet space, comfort, sound, and efficiency requirements in residential, multifamily, lodging, and other light commercial applications while offering all the advantages of VRF system technology.
The new unit is capable of providing up to 0.8 inch water gauge (wg) static pressure, and, at only 43 inches tall and 17.5 inches wide for a 2-ton model, it can be installed in tight spaces.
The flexible unit can be mounted in up-flow positions for narrow closets and basements, while horizontal left and right positions fit attic spaces. A wide range of optional electric backup heaters is available for maximum comfort and performance even in colder climates.

Newly Redesigned ProPEX Ball Valves – Uponor
Delivering higher value for residential projects and helping commercial projects meet stringent demands, Uponor North America introduced a newly redesigned line of ProPEX® ball valves for PEX-a plumbing and hydronic distribution applications.
Manufactured from premium, lead-free, dezincification-resistant brass, these full-port ball valves feature positive tube stops that ensure installers insert the valve into the pipe far enough without overextension. The valves all feature a blowout-proof stem design to ensure a lifetime of trusted reliability that professionals have come to expect from Uponor. In addition, the ASTM F1960 connection method offers a solid, strong seal without the need for glues, torches, or fire watch, providing greater safety and cost savings on job sites.

Dynamometer Line for Testing Electric Motor Efficiency – Sakor Technologies
Sakor Technologies Inc. developed a series of dynamometer systems ideal for customers required to test and verify the level of efficiency of electric motors in accordance with a variety of national and international standards, including IEC 60034-2-1, IEEE 112B, and Canadian standard C390-93. The Sakor units can be used test from two to eight pole motors ranging from 10 W to more than 3 MW.
As part of the global effort to reduce the use of fossil fuels and greenhouse gas emissions, regulators are developing energy efficiency standards for the billions of small, medium, and large electric motors used around the world. These regulations specify how to ensure motors are meeting the efficiency standards that have come into effect or are being phased in. First in line for regulation are induction motors, and it is likely that permanent magnet motors will be regulated in the coming years, followed later by inverter-driven motors.

NovoCon Digital Control Valves – Danfoss
With the new NovoCon® M, L, and XL digital actuators, Danfoss extends its range of smart actuators combined with pressure independent balancing valves (PICVs) to achieve digital control for hydronic heating and cooling systems. The new digital controls complement the existing NovoCon S for AB-QM™, ranging in sizes ½ to 1¼ inches (DN 10-32).
NovoCon digital controls enable solutions for smart building concepts. As a digital control valve, its high-precision hydronic balancing and control achieves and maintains steady room temperature requirements and design specifications (ΔT). This creates the fundamental basis for balanced comfort in commercial buildings, such as universities, hospitals, and office buildings.
The NovoCon M, NovoCon L, and NovoCon XL are specifically designed to accurately control high-flow rates in common applications, such as hot/chilled water fan coils, variable air volume (VAV), sensible-cooling terminal units, and chillers.

HVAC Airflow and Differential Pressure Sensors – Sensaphone
To help HVAC managers ensure conditions remain within required parameters in critical environments, Sensaphone offers sensors that measure airflow and differential pressure. These sensors are ideal for monitoring cooling towers, air- and water-cooled chillers, air handlers, refrigeration units, power generators, control rooms, clean rooms, computer rooms, and data centers.
The sensors are compatible with most Sensaphone monitoring devices, which provide the necessary alerting and data logging functionality. When a sensor detects a reading outside of the programmed high or low limit, the user will receive instant notification.
The Sensaphone Duct Mount Air Flow Transmitter measures the rate of airflow by monitoring the presence or absence of cool moving air. It measures relative airflow from 0-16 meters per second.
