Cloth Duct Tape Alternative Fights Mold, Extremes

Venture Tape Corp. announces Venture Tape 1507, a black line set tape designed for use on foam pipe insulation. An alternative to cloth duct tape, Venture Tape 1507 is made of a tough polypropylene film that is waterproof, weatherproof, and UV resistant. It is coated with Venture Tape’s long-life CW® acrylic adhesive, a special cold-weather acrylic that provides superior performance in extreme environments ranging from -35F to 260F. The tape contains tested and approved mold inhibiting agents, a special feature of Venture Tape products made for the hvac industry.

New DB-Differential Bypass Valve

A new Differential Bypass (DB) Valve that is designed to control excess flow in hydronic systems has been introduced by Bell & Gossett. When there is a reduction in demand, the new valve acts as a bypass while ensuring adequate flow to the remaining open circuits. Designed to be used in systems where heating loads may be excluded from the circuit as zone valves close, the DB-Differential Bypass Valve also helps reduce velocity noise caused by excess flow through the circuits while maintaining the pump head at a constant value.

Features include an all-brass body with non-ferrous internals; horizontal or vertical installation; ¾-in. connection; maximum working pressure of 150 PSIG; and a maximum operating temperature of 230F.

Victor Equipment Company announces its Cutskill 450 series for cutting and welding, designed specifically for heavy-duty applications.

Features include Victor Professional Journeyman-size regulators; steel painted gauge housings, white-faced plates, and stainless steel diaphragms; built-in replaceable reverse-flow check valves; built-in replaceable flashback arrestors; multi-fuel gas mixer in the cutting attachment; ¼ in. X 25-ft. twin RM grade hose; and more.

Redesigned Air Conditioner Eliminates Need for TXV

Improvements to the York® [mc]2 MicroChannel MiniCube 13 SEER air conditioner eliminate the need for a thermostatic expansion valve (TXV). The redesigned unit features a microchannel coil with enhanced heat transfer characteristics, enabling the unit to achieve the desired performance levels with less coil surface area, and a piston-metering device. As a result, when moving from 10 to13 SEER efficiency, the unit’s footprint remains 21¾ inches square, making it small and an ideal fit for multi-family applications, or anywhere cooling is essential and space is limited.

Available in 1 to 2½ ton sizes.
