To guard against air conditioner copper thefts, the ACAL-SHARK (Strobe, Horn, and Relay Kit) is a siren-based alarm with an integrated control board. The integrated control board eliminates the need to have a separate control panel or central alarm. 

In some cases, the proper HVACR tool simply doesn’t exist. In those instances, some entrepreneurial contractors take it upon themselves to craft their own solutions. Thus was the case with Mitch Livingston, his nephew Corey Livingston, and their ACAL-SHARK copper alarm.

Ranging from an innovative geothermal heat pump to a copper theft deterrent system, the winners of this year’s AHR Expo Innovation Awards represent a broad cross-section of the HVACR industry.

EZ-Roll™ line sets from Great Lakes Copper provide the benefit of factory assembled line sets to simplify installations, says the company. Eliminating the hassles of on-site sleeving, EZ-Roll provides tight-fitting insulation to maximize the efficiency of the system.

GL Plus™ pressurized MED/ACR copper tubing from Great Lakes Copper is available in 10-, 12-, and 20-foot lengths and a variety of sizes, both Type L and K.

Bigger is not always better, and one recent example is the new MicroGroove technology, which was introduced in 2010. This technology is defined by smaller diameter copper tubing with enhanced inner surfaces for the purpose of reducing refrigerant charge, minimizing material content and improving heat transfer.

Mueller Streamline Co. has been working with Underwriters Laboratories (UL) to conduct a series of performance tests regarding its copper tube and fittings and some of the newer higher pressure refrigerants. As a result, the company’s Streamline® copper tube and fittings are UL recognized to 700-psi operating pressures.

Siemens appoints building technologies division leader; Mueller Industries’ Streamline copper tube and fittings recognized up to 700 psi; Johnson Controls names director of marketing for unitary products; Rotobrush International announces partnership.

The Great Recession has hit few places harder than Flint, Mich. Yet Ken Hardin, owner of Ken Hardin Heating and Cooling, has found continued success through traditional cost-cutting measures and an innovative invention that is helping his customers during difficult economic times.
