Weather transmitters

WXT520 weather transmitters measure wind speed and direction, liquid precipitation, barometric pressure, temperature, and relative humidity. Outdoor measurement of temperature, relative humidity, and barometric pressure is needed to calculate the enthalpy of outdoor air. With similar information from inside a building, a building-automation system can calculate the most efficient way to reach desired conditions. Wind-speed and direction measurements can be used to improve ventilation control.

Turbine pumps

Available in 4- to 12-in. suction sizes and with 75 to 6,000 gpm, vertical turbine pumps come with high-profile ductile heads and stuffing box, stainless-steel shafting and couplings, and an optional stainless-steel basket strainer. The pumps are practical for use in condenser- and chilled-water, water-transfer, pressure-boosting, and water-supply applications.

Air conditioners

Useful for spaces in which space is at a premium, such as server/telecom rooms, CM12 ceiling-mounted packaged spot air conditioners deliver 10,500 Btuh of cooling. The air conditioners mount with standard, off-the-shelf hardware in tight drop-ceiling spaces and require no special electrical connections. The air conditioners can connect to a building-control system and works with fire-alarm controls for safety shutoff.

Web server

BCM-Web, a BACtalk control-module Web server, automatically reads building-automation-system BACnet data from Alerton's BACtalk system and translates the data to Web pages. The Web server offers quick setup and enables users to create and edit schedules, alarms, and trendlogs, which save time when jobs are updated and reconfigured. Building owners can view facility data from any Internet access point in the world.

Air curtains

Available with electric or steam and hot-water heating options, LoPro commercial air curtains deliver a stream of air that separates one environment from another, reducing air-conditioning and heating expenses and deterring flying insects to help improve sanitation levels.

Tankless water heaters

Light-commercial T-K3-Pro tankless water heaters include heat exchangers made with HRS35, an advanced heavy-duty copper alloy that is more resilient against erosions and leaks. The water heaters, which feature a thermal rating of 86 percent for liquid propane and 84 percent for natural gas, begin heating water at 0.5 gpm, but can generate an unlimited supply of hot water at a maximum flow rate of 7.0 gpm.

Scroll compressors

Apexx VSH high-capacity (12 to 40 tons of refrigeration) R-410A variable-speed scroll compressors for air conditioning and heat pumps offer continuous matching of cooling capacity to cooling load, resulting in high energy efficiency and enhanced cooling comfort. In each application range, a high-efficiency scroll compressor and variable-speed drive are designed to operate with each other and optimized for efficient performance.

Bypass technology

For motors and drives, E-Clipse bypass technology is practical for wall mounting and/or fitting into air-handling units and pumping packages. The bypasses allow building managers to keep motors in constant-speed operation, if and when drives need to be maintained. Such operation can be critical, particularly to ensure the performance of intake- and exhaust-air fans during all conditions, including fire. The bypasses communicate directly with building-automation systems.

Commercial-ventilation products

Fantech has expanded its line of commercial-ventilation products to include power roof ventilators, wall fans, and air circulators. These products join the company's line of inline exhaust fans, heat- and energy-recovery ventilators, and dryer booster fans. The fans range in size from 50 to 76,000 cfm.

Boilers

Available in six models with inputs from 900 to 3,000 mbh, HE-AB Series forced-draft gas-fired flexible watertube water boilers feature a guaranteed efficiency of 85 percent. The high combustion efficiency is caused by an integrated extended-surface heat extractor and is supported by 7 sq ft of heating surface per boiler horsepower. The boilers operate at normal operating temperatures without special venting or condensing material.
