Commercial Cooling Introductions for 2011



It’s time again for the annual Cooling Showcase. For those who are unfamiliar with The NEWS’ annual showcase, it has traditionally introduced the latest air conditioning units available for the upcoming summer season. The intent is to help contractors prepare for this busy period by doing the research that will help them to distinguish between brands.

The Cooling Showcase is split into two parts – commercial and residential. In this issue, we will focus on the commercial side of the air conditioning industry, while our April 11 issue highlighted new offerings in the residential cooling market. Included in the coverage is feature-specific information about each individual product as submitted by the manufacturers.

This showcase coverage consists of the 2011 Commercial Cooling Showcase product grid (see PDF link at the bottom of this article), which includes technical facts, such as unit tonnage, refrigerant type, efficiency rating, and cooling capacity. The photo feature below provides more in-depth information on the features of each individual unit and also includes technical support information from the manufacturer.

The manufacturers provided all of the data included in the product grid, as well as in the photo feature. Therefore, any questions should be directed to them via the contact information provided in the photo feature section.
