Copeland Scroll ZR40K3E-TFD-522 Hermetic Compressor - 3.5 HP / 33,300 BTU (3 Phase - 380-420V)

Manufactured by Emerson Climate Technologies, the Copeland Scroll ZR40K3E-TFD-522 hermetic compressor is designed to deliver maximum performance in commercial air conditioning systems, chillers and industrial process cooling applications. Featuring 3.5 HP motor power and a cooling capacity of approximately 33,300 BTU/h (11.7 kW), this model runs on a 380-420V 3-phase power supply and, thanks to its innovative scroll technology, offers high energy efficiency that lowers your operating costs.

High Efficiency and Axial-Radial Compliance

Equipped with Copeland's patented axial and radial compliance technology, this compressor provides extra protection against liquid refrigerant slugging and extends the mechanical life of the system. With low noise and vibration levels for comfortable operation, the unit works with refrigerants widely used in the industry such as R407C, R134a and R22, giving a flexible range of applications.

Practical Usage Note for Technicians in the Field

Technician's Note: When installing the compressor in the system, remember to cool the area around the tubes with a wet cloth to prevent overheating during brazing (silver brazing). The unit is factory-charged with POE oil, which is highly hygroscopic; therefore, do not remove the compressor's plugs until the very moment you braze it into the system. After installation, a deep vacuum with a quality vacuum pump is essential. In addition, if you energize the crankcase heater before the first start-up so that the oil reaches the proper viscosity, you will completely prevent mechanical wear at the first start.
