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.

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.

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.

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.

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.

Water filters
Automatic self-cleaning water filters remove micron-size suspended solids, independent of specific gravity, from water in once-through and recirculating systems, such as cooling, process, reclaim, effluent, intake, and wash waters. Single filters handle flow rates up to 12,000 gpm but can be banked to handle unlimited flows. Water-filter installation can be vertical, horizontal, or diagonal in new or existing piping systems.

Chillers
Air-cooled chillers are available from 7½ to 350 tons with integrated free cooling. Fifty-percent free cooling is achieved with ambient temperatures 10°F below chilled-water temperature and 100-percent free cooling with 20°F differential. The chillers offer energy savings for any year-round cooling application, such as data centers and other mission-critical sites. Typical investment payback occurs in less than one year.
