A-Gas, a company involved in the supply and lifecycle management of refrigerants, clean agent fire suppression, and performance chemical blowing agents, recently announced that it is expanding into Canada. A-Gas also recently announced that it has acquired Singapore-based refrigerant company, VEMAC Services.

The technological innovation of the Circlemiser air-cooled chiller series lies in the design and development of its special cylindrical condensers.

In late 2015, Two Roads Brewing Co. in Stratford, Connecticut, was looking to expand its fast-growing brewery and needed the expertise of an HVACR manufacturer to assist them. Phil Markowski, master brewer, and Mike Wight, director of operations, contacted a local HVAC contractor who put them in touch with Gregg Mello in the Carrier Enterprise (CE) Connecticut office.

HVAC chiller manu­facturers are offering a range of products in multiple configurations that use new refrigerants, consume less energy, communicate more effectively, can be serviced more easily, and may be designed to fit a wide range of applications.

Performing regular maintenance on chillers ensures they will operate as efficiently, and for as long, as possible. And while maintenance plans and practices can vary from region to region, manufacturer to manufacturer, and even client to client, HVACR contractors agree that minimal maintenance is better than no maintenance.

Optimum Energy, a provider of HVAC energy optimization for enterprise facilities, has introduced its Predictive Free Cooling software module, which is an add-on to its OptiCx Platform. The software eliminates guesswork for building operators who want to use free cooling.to reduce overall energy consumption in chiller systems.

Enterprising companies and contractors are striving to lessen the burden of this expense by optimizing chiller systems to achieve greater efficiency.

Manufacturers are on a quest to create more efficient equipment than ever before, and they're urging contractors to stay up to date on the latest technology.
