Copeland ZB21KCE-TFD-551 Scroll Compressor for Refrigeration R404A/R448A/R449A

Copeland ZB21KQE-TFD-559 Scroll Compressor for Refrigeration R404A/R507AThe Copeland ZB21KQE-TFD-559 scroll compressor is designed for medium-temperature refrigeration applications and offers a reliable solution for various refrigerants. It is characterised by its robust construction and high efficiency.Copeland ZB and ZBD scroll compressors are designed for medium-temperature refrigeration applications using the refrigerants R407A/F/C, R448A/R449A, R404A, R134a, R450A and R513AThe ZB series covers a displacement range of approximately 5.9 to 87.5 m³/hThe digital ZBD models allow for stepless capacity modulation, typically from 10 to 100 %Copeland scroll compressors have significantly fewer moving parts than reciprocating compressors and feature a set of spirals that are axially and radially flexible, making them particularly robust against operational disturbances (e.g. liquid slugging)Thanks to their compact, lightweight design, they are ideally suited for chillers, compact refrigeration systems and process coolingThe Summit models (approx. 7–15 HP) are designed for high seasonal efficiency and achieve up to around 15 % higher efficiency than comparable semi-hermetic piston compressorsIf required, an optional soundproofing hood can reduce the noise level by up to approximately 10 dB(A)Axial and radial flexibility of the scrolls ensures high reliability and efficiencyWide operating range with low condensation temperatures and rapid cooling capacitiesHigh seasonal efficiency, optimised for typical operating pointsLightweight and compact design, weighing up to about half as much as comparable semi-hermetic piston compressorsOptional soundproofing hood for additional noise reductionDigital ZBD models for stepless capacity modulation (approx. 10–100 %)one compressor type for multiple refrigerants (R407A/F/C, R448A/R449A, R404A, R134a, R450A, R513A)Maximum permissible operating pressure (PS): ZB15 to ZB45: Low-pressure side 21 bar(g) / High-pressure side 32 bar(g)Maximum permissible operating pressure (PS): ZB50 to ZB114: Low-pressure side 22.6 bar(g) / High-pressure side 32 bar(g)Maximum permissible operating pressure (PS): Digital ZBD: ND 21 bar(g) / HD 28.8 bar(g)Maximum permissible operating pressure (PS): Summit ZBD: ND 22.6 bar(g) / HD 32 bar(g)Technical detailsMBP application rangeNumber of phases: 3Design: HermeticdB(A) 69Pressure line (inches) 1"Electronics includedFrequency 50–60 HzWeight 29Displacement 8.61 m³/hCooling capacity (kW) 55Refrigerant R134ARefrigerant R404ARefrigerant R507ARefrigerant R22Capacity at operating conditions: -10°C evaporator temperature; 45°C condenser temperature; 20°C suction gas return; 0 K subcooling for R-404A at 50 HzMax. operating current (A) 7Motor code TFDPre-filled oilOil quantity (l) 1.24Oil type: POEProduct family ZBSuction pipe (inches) 1 1/4"Compression type: ScrollSupply voltage 380–420 VSupply voltage 460VAdvantages and benefitsHigh reliability and efficiency thanks to the axial and radial flexibility of the scrollsOptimal performance at low condensing temperatures and with high cooling capacitiesLow weight and compact design allow for easy integration into various applicationsOptional soundproofing hood reduces noise levels and improves comfort Note:Oil: The compressor is pre-filled with oil at the factory.
