The RevFlo (no gauge) and the RevFlo-G (with a gauge) reversible flow units are additions to the Heater Treater® line of scale prevention systems for tankless water heaters. The units incorporate a newly created mounting bracket that can be adjusted on the head assembly of the housing, allowing the water to flow in either direction. 

The Infinity® Touch Control, the next generation of touch-screen communicating controls, provides Touch-n-Go™ programming and energy-management features when utilized as part of a complete Infinity HVAC system. With Touch-n-Go programming, a homeowner can control the temperature, humidity, and fan speed. 

The FAMCO IAQ Economizer™ kit is a control system designed to provide cutting-edge economizing, free-cooling, and IAQ functionality to split-system air conditioning systems by using external air to reduce internal temperatures. It allows low temperatures to be realized at times when they can be achieved using less energy. 

Refrigerant leak detector Model 316-3 is a hand-held detector that delivers optimal sensitivity to all refrigerants, detecting leaks as small as 0.15 oz/year. The detector is resistant to contaminants such as dust, dirt, and oil, the company said. 

The high-efficiency, variable-speed CSV Series screw compressor features an integrated frequency inverter. The inverter is cooled by refrigerant and includes automatic, infinitely variable-speed control to ensure the right temperature profile at the lowest possible power consumption. 

The Automatic Tube Cleaning System (ATCS) provides energy-saving, on-line condenser tube cleaning for water-cooled chiller applications. The system periodically injects sponge balls into the condenser water stream, and prevents condenser tubes from developing scale or microbial fouling deposits.

Model DDSM1 draft simulator allows HVAC professionals to accurately test pressure switches and calibrate adjustable pressure switches to any furnace. This allows technicians to carry adjustable switches on their trucks, instead of switches for a variety of furnaces, said the company.

With the HOBO wireless temp/rh monitoring kit, users can monitor critical temperature and humidity conditions, log data for trend analysis, and stay notified of alarm conditions via text or email. Features include centralized monitoring straight from the desktop. 

Designed for high-voltage fan coil and baseboard applications, the SimpleComfort® SC700 series of fan coil thermostats includes four UL-listed, nonprogrammable models. They support 24 or 115-277 vac, three-speed fan, four-pipe heat/cool applications with precise comfort controls accurate to ±1°F. 

The 175-gallon capacity model has been added to the Heavy Duty Electric line of commercial water heaters. According to the manufacturer, when an order is placed before noon, the manufacturer will either ship the 175-gallon model the same day or customers can pick it up the same day.
