Emerson Copeland Scroll Compressor YB81K1G-TFDN-JCE for R290 refrigerant (propane)

Emerson Copeland Scroll compressor YB81K1G-TFDN-JCE is a three-phase refrigeration compressor designed for operation with R290 (propane, A3 flammable refrigerant) in medium-temperature applications. Power supply 380–420 V / 3~ / 50 Hz, displacement 36.40 m³/h at 2900 rpm and cooling capacity 17.7 kW (according to manufacturer data for R290) make it a suitable solution for condensing units, central systems and refrigeration equipment using natural refrigerants.

Features, advantages and benefits

• Operation with R290 (propane) → natural refrigerant with a very low global warming potential; installations using R290 typically require about half the refrigerant charge compared with HFC systems. → easier adaptation to F-gas restrictions and a smaller amount of refrigerant in the circuit.
• Copeland Scroll compressor (single scroll set driven by a three-phase motor) → the scroll compression system handles temporary liquid refrigerant in the suction line (e.g., during flooded starts). → greater resistance to typical transient disturbances in refrigeration systems.
• Three-phase motor 380–420 V / 50 Hz and 460 V / 60 Hz, without capacitor → one compressor supports both 50 Hz and 60 Hz networks, and the design does not require a starting capacitor. → simpler wiring and broader applicability in equipment for European and export markets.
• Motor thermal protection (Thermally Protected) → the motor is protected against overheating. → lower risk of winding damage in the event of overload or system failure.
• Terminal box with IP65 protection rating → protection against dust and water jets at the point where power cables are connected. → safer operation in demanding conditions, e.g. in outdoor-mounted condensing units.
• PAG RLF 68 EP oil in the amount of 3.40 l → factory fill with oil matched to propane operation. → the compressor is ready for installation without selecting the original factory oil, and during service it is clear which oil to use.
• Cooling capacity 17.7 kW (R290, evaporation temp. −10 °C, condensation temp. 45 °C, superheat 10 K, subcooling 0 K, 50 Hz) → clearly defined reference conditions. → easier selection of the compressor for a condensing unit or central system with a known cooling capacity.

Technical data

Application

The YB81K1G-TFDN-JCE compressor is intended for medium-temperature refrigeration systems operating on propane (R290), including condensing units, refrigeration plants, commercial and catering refrigeration equipment, as well as compressor replacement in systems designed for R290. Before selection, check compatibility with the existing system and with the Copeland application guidelines.

Frequently Asked Questions (FAQ)

Which refrigerant does the YB81K1G-TFDN-JCE compressor operate with?

YB*K1G series compressors are designed for R290 (propane), classified as a flammable A3 refrigerant. It should not be used with other refrigerants without confirmation from the manufacturer.

What power supply voltage is required?

The compressor is three-phase: 380–420 V at 50 Hz and 460 V at 60 Hz. It is not designed for single-phase power supply.

What is the compressor displacement?

36.40 m³/h at 2900 rpm (50 Hz) and 43.90 m³/h at 3500 rpm (60 Hz).

What are the maximum operating current and starting current?

The maximum operating current is 28.2 A. The locked rotor current (LRA) is 133–140 A at 50 Hz and 150 A at 60 Hz – these values should be considered when selecting protection devices and supply cables.

What oil is in the compressor and how much is there?

The compressor is factory-filled with PAG RLF 68 EP oil in the amount of 3.40 l (114 oz).

Does the compressor require a starting capacitor?

No. The compressor nameplate indicates no capacitor (No Capacitor).

What are the allowable pressures and temperatures?

The maximum allowable pressure PS is 32 bar on the high-pressure side and 14.0 bar on the low-pressure side. The allowable temperature TS on the low-pressure side is in the range from −35 °C to 44 °C. The compressor falls under PED category 2.
