In late March 2012, ClimateMaster announced an efficiency breakthrough with the introduction of the Trilogy™ 40 se­ries, the first geothermal heat pumps ever certified by the Air Conditioning, Heating, and Refrigeration Institute (AHRI) to exceed 40 EER (energy efficiency rating) at ground-loop conditions.

The outcome of a five-year-collaboration between ClimateMaster and ORNL’s Building Technologies Research and Integration Center, the revolutionary Trilogy™ 40 uses variable-speed technology to provide an extremely wide range of heating and cooling capacities, with the ability to perfectly match loads to as low as 30% of maximum. Based on field tests and analysis by ORNL, the Trilogy 40 Q-Mode can save 55–65% of annual energy use and cost for space conditioning and water heating in residential applications versus new minimum efficiency (SEER 13) conventional sys­tems and 30–35% versus current state-of-the-art two-stage geothermal heat pumps.

"The Trilogy 40 Q-Mode represents a major break­through in comfort and efficiency," said John Bailey,  senior vice president of sales and marketing at ClimateMas­ter. "With variable-speed fan, pump and compressor (Trilogy technology) plus four operating modes (Q-Mode technol­ogy), it far exceeds the capabilities of any other HVAC unit on the market today. Plus, it can completely eliminate the use of auxiliary heat even in far northern climates."

Headquartered in Oklahoma City, ClimateMaster is the leading manufacturer of geothermal and water-source heat pumps, which are considered to be the most energy efficient and environmen­tally friendly type of heating and cooling systems available on the market today. The Trilogy 40 Q-Mode series is currently in limited production, with full availability scheduled for late 2012.
