Stew Leonard's
Danbury, CT
As the world's largest dairy store, refrigeration is key to Stew Leonard's success. Stew's Danbury store sports a 10,000 square foot refrigerated storage room and a 5,000 square foot freezer storage room - plus seemingly endless in-aisle cold cases that are vital to Stew's famous in-store atmosphere. When the time came for an upgrade from R-22 refrigeration to R-404A and CO2, Stew Leonard's chose McKenney Mechanical.
12,000 hours of minus 20F working conditions - mostly 3rd shift. Strict business continuity requirements. Cutting edge, massive-scale systems. And 2 miles of new glycol piping store wide. This was not your everyday refrigeration retrofit. But, McKenney is not your everyday refrigeration contractor. Tight project management, unparalleled in-house prefab capability, and focus on safety meant the project was completed with continuous store operation and no accidents. And McKenney continues to provide onsite preventative maintenance and emergency service.

Danbury Hospital
Danbury, CT
Danbury Hospital's 371 bed facility plays an important role in providing health services to the surrounding community. A facility dedicated to saving lives requires its power source to be reliable regardless of surrounding disasters. A 4.5 Megawatt cogeneration power plant makes Danbury Hospital independent of the power grid while reducing carbon footprint and energy consumption.
The plant consists of one 4.5 Megawatt natural gas fired turbine which provides electrical power for the building. During winter, heat captured from the turbine's exhaust supplements the building's heat. During summer, the exhaust heat is put through an absorption chiller which supplements the buildings cooling.
Easy to say. Hard to build. Hospital operations have to continue. Complex high-pressure stainless steel piping with 100% x-ray testing of welds were required. McKenney Mechanical was up to the challenge. And completed the job - safely.

Hommocks Park Ice Rink
Mamaroneck, NY
An ice rink represents the most demanding of large scale refrigeration and HVAC challenges. High load requirements and high-humidity conditions means HVAC/R equipment can take a real beating. After 30 years of use, the Hommocks Park Ice Rink needed a major refurbishment. As Mamaroneck's largest energy user, town engineers sought to leverage more efficient designs and technology while providing a face lift for recreational skaters and local hockey teams.
McKenney Mechanical rebuilt the entire ice making and refrigeration plant - installing new chillers, dehumidification and condensing units. The project included construction of a 3,000 square foot addition to house the new plant as well as complete reconstruction of the ice rink itself. The refurbished rink greatly reduces the town's energy costs while extending the rink's use from 9 months per year to year round.
Demanding energy efficiency requirements. The latest in cutting edge technology. McKenney Mechanical delivered and the renovated ice rink opened on schedule and to the delight of local skaters.
