Four fans connected in parallel provide built-in redundancy in the PowerAire® Quad fan assist module. Designed for data center installations, the module manages the cooling requirements for dense server racks and blades. It provides a blast of cooling through the DirectAire® airflow panel.

A line of PVC and CPVC duct dampers offered in butterfly, gravity, and blast gate types for fume removal applications is available. The backdraft dampers come in three flow control types: butterfly for balancing airflow, a gravity backflow preventer which closes when the air pressure stops, and a blast gate for on-off.

The Therm C 1050 ES tankless water heater has had an efficiency increase of 2 percent made to it; increasing its total energy factor (EF) to 0.94. Also, the C 1050 ES, along with three other Therm models meet the new, stricter, Low NOx requirement passed by utility regulatory agencies in California and Vermont.

The 2012 Kühl room air conditioner with optional Wi-Fi control is a room cooling solution that can help simplify building operations management and curtail energy consumption in dorms, apartments, commercial, and industrial facilities. Facilities management personnel can remotely control units.

The nation is ready for renewable energy products. It just might not know it yet. Not all contractors are experiencing this majority interest. In fact, some have found that for different reasons, some of their customers are not interested at all. How can they overcome customer objections?
