Condensing Units
Split System Cooling Units . . .
The Evolution Continues
2TTB0, 2TTA0 split systems represent a product that is not only an engineer’s dream, it’s also a customer’s dream. The design team’s mission and accomplishment is enhanced performance and efficiency, improved reliability and durability, and improved installability and serviceability. Trane’s experienced design team applied
“six sigma principles”, the latest computer technology and customer research to develop the next generation of leadership outdoor products. Couple the Trane reputation for reliability and durability with the above mentioned mission and accomplishments and you continue to have systems that prove “It’s Hard to Stop a Trane®. ”
This unit must be designed to operate at outdoor ambient temperatures as high as 115°F. Cooling capacities shall be matched with a wide selection of air handlers. Exterior must be designed for outdoor application.
Casing
Unit casing is constructed of heavy gauge, galvanized steel and painted with a weather-resistant powder paint.
Corrosion and weatherproof CMBP-G30 Duratuff™ base.(2TTB/2TTA)
Refrigerant Controls
Refrigeration system controls include condenser fan and compressor contactor. High and low pressure controls are inherent to the compressor. Another standard feature is the liquid line dryer.
Compressor
The Climatuff® compressor features internal over temperature and pressure protector, total dipped hermetic motor and thermostatically controlled sump heater. Other features include: roto lock suction and discharge refrigeration connections, centrifugal oil pump, and low vibration and noise.
Condenser Coil
The Spine Fin™ coil shall be continuously wrapped, corrosion resistant all aluminum with minimum brazed joints. This coil is 3/8 inch O.D. seamless aluminum glued to a continuous aluminum fin. Coils are lab tested to withstand 2,000 pounds of pressure per square inch. The outdoor coil provides low airflow resistance and efficient heat transfer. The coil is protected on all four sides by louvered panels and has a 10 year limited warranty.
Low Ambient Cooling
As manufactured, this unit has a cooling capability to 55°F. The addition of an evaporator defrost control permits operation to 40°F. The addition of an evaporator defrost control with TXV permits low ambient cooling to 30°F.
