Why is Trane different from other manufacturers?
The Trane Climatuff® compressor was the world's first successful heat pump compressor. Over the years, its reputation has been built on the fact that it handles the extreme operating conditions of heat pump applications with ease. For example, a compressor's reliability is directly related to its ability to handle stress. The Climatuff's all-aluminum frame not only dissipates heat, but its light weight reduces stress on its mounting springs, as well. Valves are another critical factor because they experience more stress than any other component. For that reason, Trane manufactures compressor valves to extremely tight design specifications.
A large shell volume is another Trane difference. Climatuff® reciprocating compressors have more volume inside the shell than other compressors, which gives it an additional safety margin against slugging, often caused by overcharging or low indoor airflow. The differences add up to the most durable compressor manufactured in the industry today. Read on.
Designed To Handle Thermal Stress.
The Climatuff® compressor's stress handling ability begins with its aluminum frame, and its aluminum pistons and connecting rods. An aluminum frame reduces thermal stress and allows the compressor to run cooler than compressors with cast-iron frames, which tend to retain heat, resulting in higher operating temperatures.
The frame is designed with a very large intake area to minimize the pressure drop of suction gas. Suction gas flow to the valve is virtually unrestricted.
The lightweight aluminum pistons and connecting rods provide for easy starts and relieve stress on the crankshaft. Trane uses an industry-unique pearlitic cast-iron cylinder liner for enhanced durability.
