Budget and delivery speed have always been challenges when designing an HVAC or pressure boosting system, but system efficiency is becoming a bigger concern every year.

If you suddenly have the need for a two-way, flow control valve — from a valve-selection standpoint — what kind of questions do you ask yourself?

Distributing water on a large scale has been a challenge that the world has tackled for decades.

Taco Comfort Solutions’ 0018e high-efficiency circulator now features Bluetooth communication to a mobile app, providing real time control, diagnostics and reporting, such as installation history, power consumption, performance, and runtime. Installers can select between multiple constant speed, proportional pressure, and constant pressure modes as well as activeADAPT™, Taco’s self-adjusting proportional pressure mode.

The new TYCO DV-5A deluge valve from Johnson Controls offers improvements on the DV-5 valve while keeping the original key features. The company says DV-5A deluge valve has a higher pressure rating of up to 300 psi and lower pressure drop, allowing water to travel further at specified system pressure.

The YORK® brand of Johnson Controls has released two new commercial units — the 6.5- to 12.5-ton Predator™ series and 15- to 23-ton Large Sunline™ series. With efficiencies reaching as high as 21 IEER, these products comply with requirements set by the United States Department of Energy (DoE), ASHRAE 90.1-2013, 2015 International Energy Conservation Code, and the Consortium for Energy Efficiency’s Advanced Tier*.

What risks are being taken to not measure/monitor/control airflow directly and who is at risk?

Biosafety Level 3 (BSL-3) space pressurization is critical to reducing the potential spread of infectious diseases in laboratories.
