Occupancy scheduling without an energy management solution is performed by the Wi-Stat IIIp-S, a standalone programmable pneumatic thermostat. The thermostat is designed for easy retrofit to existing two-pipe pneumatic HVAC infrastructures without disruptive and expensive rewiring.
The WhisperRecessed™ ventilation fan is an 80-cfm fan-light combination that is recessed into the ceiling offering quiet, energy-efficient, and powerful ventilation. The Energy Star®-rated compact fluorescent lamp provides diffused, uniform illumination with the 18-W CFL bulb.
The Econar® ColdClimate™ Series of geothermal heat pumps is designed to meet the demands of heating-dominant climates without sacrificing efficiency, said the company. The series features heat-cool balance and leaving air temperatures of up to 106°F. TruBalance™ technology regulates heating and cooling operation.
NeoTherm® LC condensing boiler is a fully packaged, 1 million Btu, space-saving hydronic unit that offers 94 percent thermal efficiency. It is a direct vent, sealed combustion boiler that modulates with a 10 to 1 turndown. Zero clearance to combustibles with all piping and wiring from the back makes it a good choice for tight installations.
With the 38-inch telescoping probe, a line of in-duct HVACR instruments — two psychrometers (SRH3 and ARH5) and a hot-wire anemometer (STA2) — makes it easier for techs to take temperature, percent rh, or air velocity readings in the duct. The standalone STA2 uses a hot wire for measuring air velocity.
With a capacity of 25 tons of refrigeration, the Performer® SH295 scroll compressor for air conditioning has been added to the manufacturer’s large commercial scroll compressor portfolio. Cooling capacities range from 183 to 374 kBtuh/53 to 110 kW at 60 Hz and 150 to 310 kBtuh/44 to 90 kW at 50 Hz.
Lightweight, the BT-637 portable bench-top airborne particle counter can monitor particulate matter, temperature, and relative humidity in the workplace and verify the health and safety of the environment. The particle counter can detect airborne particles in the mold spore size range of 1-10 microns in diameter.
The Add-A-Wire™ thermostat accessory allows for the easy addition of extra wiring to virtually any 24-V thermostat in applications where additional wiring otherwise cannot be added. According to the manufacturer, the accessory is easy to install; allows five-wire thermostats to work with only four wires; and more.
Added to the WattNode® family is the WattNode BACnet® meter (MS/TP), which offers cost-effective energy and power metering for building automation communications protocols. The meters provide line-powered single- and three-phase wye or delta configurations up to 600 vac and 6,000A.
