Heatcraft Refrigeration Products introduced its intelliGen™ Refrigeration Controller, the newest addition to the Heatcraft controls portfolio. intelliGen is a factory-mounted electronic controller that aims to deliver reliable operation and improved system efficiency. Officials said the controller helps reduce product spoilage by maintaining better temperature control and provides energy savings through optimizing defrosts.

Heat Transfer Products Group LLC released its new EcoNet® Enabled Unit Coolers. Developed in conjunction with Rheem Manufacturing, the company says it builds on the efficiency of Rheem’s EcoNet® technology and brings it to the commercial refrigeration market.

In May 2017, this column addressed additions to existing BAS. It recommended that most building owners should sole-source these projects using the base-building’s BAS manufacturer.

Greenheck’s new line of ceiling radiation dampers are UL classified for installation in wood truss floor/ceiling assemblies. Model CRD-1WT is designed with a plenum box for side inlet or outlet duct connections. Model CRD-2WT’s inlet or outlet duct connection is made on top of the damper.

The new Metasys® 9.0 building automation system from Johnson Controls offers enhancements to the Metasys product line, including two new IP/Ethernet-based controllers and user interface (UI) features that make finding critical information and resolving issues easier, according to the manufacturer.

Carrier is offering an electronically commutated motor (ECM) direct-drive fan option for the Aero® 39M commercial air handler product line. According to company officials, adding the new ECM fan option enables customers to further improve the system’s energy efficiency. Onboard electronics determine the position of the rotor, which then provides an electronic pulse to actuate the motor windings.

Johnson Controls says its new SMART Equipment Controllers (SEC) use a smart mobile device interface that gives engineers the flexibility to easily access their Johnson Controls water-to-air water source heat pump controls through any Wi-Fi-enabled device and any internet browser. The controllers feature an onboard backlit local display with pushbuttons and BACnet Automatic Discovery support that enables integration into any BACnet BAS.

Today, in 2016, we often see BAS installed in new commercial buildings with microcontroller hardware that was designed up to 10 years ago.
