An improved version of the Minneapolis Blower Door™ can be used to measure the airtightness level of building envelopes, diagnose and demonstrate air leakage problems in buildings, estimate natural infiltration rates, estimate efficiency losses from building air leakage, and certify construction integrity.
The Lubi™ solar air heater features significant energy savings and quick paybacks for commercial, institutional, and industrial facilities. The wall-mounted solar collector simulates an aesthetic architectural glass-like facade, and provides up to 80.7 percent peak heating efficiencies.
The redesigned Q-TRAK™ multifunction IAQ Monitor Model 7575 provides real-time, simultaneous display of up to five key IAQ parameters including temperature, relative humidity, CO2, and CO quickly and accurately. The monitor also calculates dew point, wet bulb temperature, and percent outside air.
The gasoline-powered N-Series trucks are powered by a General Motors Vortec 6.0-liter V8 engine that produces 297 hp at 4,300 rpm and generates 372 foot-pounds of torque at 4,000 rpm. The NPR (12,000-pound GVWR) and NPR-HD (14,500- pound GVWR) trucks are available in single-cab models.
The Wireless Comfort™ zone control panel is part of the Wireless Comfort zoning system line. The line is unique, as all components are wireless, including the dampers and thermostats, says the company. The installer is not required to cut drywall and run wires, which helps keep labor fees low and labor time down.
The DA 3500i portable dehumidifier offers the highest water removal capacity available in a portable unit both in low and high humidity settings, says the company. The dehumidifier removes 170 pints at Association of Home Appliance Manufacturers (80°F/60 percent rh) while drawing only 10.5 A.
The Porta-Vac 23 air duct cleaning vacuum can be transported to a jobsite and wheeled to a convenient exterior location. According to the manufacturer, the machine uses shorter, more efficient hose runs and an external filter bag for near truck-mount performance. It offers more power than an electric unit.
The Route multivehicle route planning, optimization, and scheduling system has been enhanced with new advanced business analysis tools. The tools expedite the integration of customer requirements into the software, and build intelligent routes that take into consideration such variables as driver schedules.
The crawl space ventilation unit ventilates the entire crawl space, controls the airflow by utilizing replenishment air exclusively from the upper levels, and maximizes air circulation. The unit extracts moisture and air pollutants out of the crawl space and maintains a drier and healthier environment.
The T620 and T640 professional-grade thermal imaging cameras offer a 307,200 pixel (640 x 480) infrared resolution coupled with 2 percent accuracy, <0.04° to <0.05°C thermal sensitivity, a 2,000° temperature range, and available 8x digital zoom. The cameras feature a 4.3-inch touchscreen.
