The flooded evaporator technology reduces operating costs by approximately 10-12 percent, says the company. The Bubble Expansion Valve washes cold refrigerants through 100 percent of the evaporator. The control signal for regulating refrigerant is via the condensate instead of from the superheated evaporator return gas.
Sound Blankets are now available for commercial compressors. Their universal-fit design makes them compatible with most brands of scroll and reciprocating compressors from 5 to 30 tons. They provide a 5-dB noise reduction, minimum, which is about a 40 percent decrease, says the company.
The Hi-Velocity pulse width modulation (PWM) control is unique in the small duct, high velocity sector because it is a true energy-saving zoning control system, claims the company. The controller is pressure-reactive and will change the energy input to maintain constant cfm flow of open outlets from 150-1,250 cfm.
The Ward Industries duct connection product Quick Flange™ cuts flange installation time in one-half for commercial and industrial ductwork applications, saving time and money for ductwork fabricators without reducing connection strength, says the company.
The Copeland Scroll® outdoor condensing unit is designed for medium- and low-temperature refrigeration applications. With advanced PerformanceAlert™ diagnostics and a fault history feature, it offers diagnostic protection capabilities for the entire system and permits more accurate troubleshooting.
The portable superlight professional welding kit is, according to the manufacturer, the first one of its kind that uses disposable cylinders. The combination of Map-Pro and oxygen guarantee high output temperatures up to 5,500°F. The disposable cylinder eliminates the cylinder’s recharge lead time.
EZ-Ject™ dye injection kits feature the EZ-50 dye injector assembly, an a/c hose/coupler with check valve and ¼-inch flare low-loss fitting, two EZ-Ject dye cartridges, and a purge fitting. The dye injector is said to be easy to use because it requires only one connection to add dye into an a/c or refrigeration system.
The AXTC fiberglass tubular in-line centrifugal fan features the design advantages of an axial fan with the airflow and pressure capabilities of a centrifugal fan, says the company. The fan offers several standard configuration options for duct (horizontal or vertical) or roof mounting.
Uni-Wrap is a strong, puncture-resistant, polyethylene plastic that can be used for the temporary protection of the open ends of HVAC sheet metal ductwork and other construction materials during transit and jobsite storage. When applied to ductwork, it seals out dust, dirt, rain, snow, paint, and other contaminants.
TC Series single-stage, double-suction, vertical split case pumps are designed for commercial heating, a/c, pressure boosting, cooling water transfer, and water supply applications. Top suction and discharge are said to make this product an ideal choice for minimizing installation footprint in tight mechanical rooms.
