The Series UA infrared heaters offer rates of 40,000-220,000 Btuh. They can operate on natural gas and LPG, have gas connections of ½-inch NPT, and natural gas minimum gas inlet of 5-inch wc and LPG minimum gas inlet of 11-inch wc. Standard lengths range from 10 to 60 feet; extension options are available.
The Traceable® handheld digital barometer measures altitude, temperature, and barometric pressure. It also has a stopwatch/time-of-day clock, compass, and graphically displays the barometric pressure trend. The barometer measures barometric pressure from 8.85 to 32.45 inches of mercury (inHg).
The York® YVAA air-cooled variable-speed screw chiller uses R-134a refrigerant. Fewer joints and potential leak points keep the refrigerant inside the system, while a proprietary falling-film evaporator and advanced microchannel condenser coils reduce the refrigerant charge by as much as 15 percent.
Two filters have been added to the portfolio of Filtrete™ Commercial HVAC filters. The MERV A13 and MERV A11 are designed with an innovative open filtration media structure, precision pleat structure, and high-surface area mini-pleat design, resulting in low pressure drop, thereby helping decrease energy use.
A family of clamp meters and a four-channel oscilloscope is engineered to give users ways to work safely and reduce their exposure to electrical shock. The 381, 376, 375, and 374 current clamps and iFlex™ current probes are rated for use in measurement category IV environments (CAT IV 600V, CAT III 1,000 V).
The manufacturer’s Energy Star®-qualified ventilation products include exhaust fans and range hoods. The exhaust fans include the ECO-Exhaust Fan Series, Deluxe Quiet Series, the Quiet Series, the High-Performance Exhaust Series, and Fire-Rated Exhaust Series.
The Aegis™ SGR bearing protection ring protects the bearings of VFD-driven motors from electrical damage, and the Aegis universal mounting kit (U-Kit) simplifies its mounting on virtually any ac motor shaft. The kit includes the Aegis grounding ring and mounting hardware for most motor designs.
The BAS 1P™ single-phase motor starter is designed for use with exhaust fans, unit ventilators, and fan coil units in installations that have building automation systems, occupancy sensors, or timers. With electronic overload protection, the starter is flexible enough to thermally protect all single-phase motors up to 1 hp.
The AMI300 Series IAQ analyzer is a hand-held instrument designed to make analyzing on-site simple. It is an all-in-one tool for measurement and verification of air quality, including temperature and differential temperature, humidity, dew point, wet bulb, enthalpy, air pressure and air velocity, CO2, CO, current, and voltage.
The butterfly damper has a built-in virtually airtight permanent gasket and can be used in residential and commercial ventilation systems. According to the manufacturer, the nearly 100 percent efficient performance of the butterfly damper also helps prevent off-season condensation.
