A new generation of copper brazed heat exchangers feature design improvements that provide higher thermal efficiency performance, resulting in energy and cost savings. Models CB30, CB60, CB110, and CB112 cover a wide range of duties and will replace the CB27, CB52, CB76/77, and AC120 models.

The Evolution® Extreme variable-speed heat pump (280ANV) has efficiencies of up to 13 HSPF and up to 20.5 SEER. When combined with an Evolution control and Evolution gas furnace or fan coil, the heat pump utilizes a variable-speed compressor to precisely match its operation to the heating and cooling needs of the home.

Featuring low-H2O technology that enables the unit to heat quickly, the Linea Plus radiator can be used with low-temperature hydronic systems and renewable energy sources such as solar or geothermal. The discreet design allows for pipes and vents to be completely hidden behind the front panel and cabinet.

The B26 AsyMatrix® brazed plate heat exchanger (BPHE) is designed for heat pumps. It is an asymmetric condenser for ground-source and reversible air-to-water heat pumps with a wide capacity range between 5-40 kW.

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.

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 lightweight Tradesman Pro™ Organizer Backpack (SKU# 55421-BP) provides 39 pockets for maximum tool storage. A large front pocket can easily fit service books, computers, and iPads. The wide opening of the interior fits power drills, meters, and flashlights, while the rugged molded bottom protects tools.

The Eternal Hybrid™ GU100 water heater offers endless hot water and is Energy Star listed at 0.94 EF (energy factor). The water heater can support up to two simultaneous applications, such as running two showers or a shower and a dishwasher at the same time.

The redesigned Model TZ-60B is part of the Topaz® line of portable air conditioners. The 6-ton portable air conditioner offers 76,500 Btuh of cooling and can also provide heat with a built-in electric heat coil. Other new features on the TZ-60B include a digital programmable thermostat.

By combining auto-ranging and auto-zeroing technology, the DP-702LH differential air pressure (∆P) sensor board offers low-end sensitivity and a broad measurement range. The unit incorporates a 250-Pa (1 inch H2O) range sensor and a 10-kPa (40 inches H2O) sensor on the same board.
