Dayton Lamina™ hydraulic motors feature a design that allows four-times the torque to be produced at a quarter of the speed without gear reducers. According to the manufacturer, with torque ratings comparable to larger motors, they save size, weight, and cost over larger similarly rated motors.
Krueger-HVAC now offers five different models of blower coils that are divided into three different groups: Standard, Small Footprint, and Modular. The new models include KBH (standard, horizontal blower coil), KBV (standard, vertical blower coil), KSB (small footprint, vertical blower coil with rear return), KSL (small footprint, vertical blower coil with bottom return), and KBM (modular blower coil).
According to Johnson Controls, its York LX Series packaged units set a higher standard to heat and cool residential and light commercial buildings, featuring a contractor-friendly design, reliable technology, and an advanced manufacturing process. The units are 29% more efficient, earning a 14 Seasonal Energy Efficiency Ratio (SEER) rating and exceeding U.S. Department of Energy efficiency standards.
The Drives & Motion Division of Yaskawa America, Inc. has released three new motion control products. Each of the new devices is designed to improve the performance of automation systems, and to compound the improvement in system effectiveness when used in combination.
Camfil Air Pollution Control (APC) says its new HemiPleat® Synthetic dust collector filter combines a high-efficiency synthetic media with proprietary open-pleat technology for excellent performance and long life in harsh, humid environments.

E+E Elektroniks has expanded its product range with various sensors for passive temperature measurement for HVAC and building technology. The compact enclosure with protection class IP65/NEMA 4 facilitates allows for easy and fast installation of the sensors, according to the company. Due to external mounting holes the sensors can be installed with closed housing, which protects the device from building site contamination. The new temperature sensors line matches the design of the E+E humidity, CO2, and air velocity sensors.
Gems Sensors & Controls has announced the global market introduction of its F Series. The company says its F Series is a family of ruggedly designed solenoid valves, offering high-reliability for flow rate applications with a lifespan of up to 10 million cycles.
Trane is now offering its Air-Fi™ wireless technology for building controls. The company reports that Air-Fi wireless replaces the need for wired building controls, allowing installations to be completed quickly with less disruption to occupants in existing buildings, while also providing greater reliability, simplified installation, and more flexibility as building spaces change.
Leaning on experience and data from various K-12 cities and projects, the author pursues some less conventional design approaches. They may revolve around radiant heating and/or cooling, but depending on school size and other factors, the smart use of heat recovery, DOAS, and improved central plants could also put a project on the HVAC honor roll.
