The GeoComfort® Compass Series geothermal outdoor split system can be installed in new and existing homes. The space-saving footprint makes it an excellent choice for homes with minimal space for mechanical equipment, said the company. 

Five million- (FBN5000) and 4 million-Btuh (FBN4000) units have been added to the Crest® condensing boilers. The line also has been expanded to include a dual-fuel gas train. Additional product enhancements include lower-firing input-derate numbers in high-altitude applications.

A complete line of laser-built, insulated, metal-building roof curbs is available. The curbs are fabricated using 14-gauge and 18-gauge AZ-55 GALVALUME® material with welded construction, built-in diverter, and integral conforming notches for compatibility with GALVALUME roof panels and a water-tight seal. 

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.
