Compressor Bristol H7NG244FRDF, R407C, 220V/3F/50Hz, 54.5 kW, Rotalock

Copeland ZR250KCE-TWD-523 Scroll Compressor for Air Conditioning/Heat Pumps R134A/R407CThe Copeland ZR scroll compressor is designed for comfort, process and precision cooling using the refrigerants R513A, R407C and R134a. Typical applications include chillers, rooftop air-handling units and precision air-handling units. By using multiple Copeland-certified tandem and trio combinations, higher capacities can also be achieved with high seasonal efficiency.Copeland ZR scroll compressors are designed for comfort, process and precision cooling using the refrigerants R513A, R407C and R134aTypical applications include chillers, rooftop air-handling units and precision air-handling unitsBy using multiple Copeland-certified tandem and trio combinations, even higher capacities (e.g. air-cooled chillers up to approx. 500 kW) can be achieved with high seasonal efficiencySpecial ZR models for R513A (GWP 631) are available to meet current requirements for low GWP valuesThe series covers approximately 2 HP to 30 HP (ZR24–ZR380 for R407C/R134a, ZR24KRE–ZR190KRE for R513A/R407C/R134a) and, thanks to low superheat (approx. 5 K), enables good system optimisation and cost reductionAxial and radial flexibility of the scrolls ensures high reliability and efficiencyExtensive ZR range for R407C, R134a and R513ALow TEWI (Total Equivalent Warming Impact)Low noise and vibration levelsLow oil carryoverCopeland-certified tandem and trio configurations for high seasonal efficiencyMaximum permissible operating pressure (PS): ZR24 to ZR81: ND 21 bar(g) / HD 29 bar(g)Maximum permissible operating pressure (PS): ZR108 to ZR380: ND 20 bar(g) / HD 32 bar(g)Technical detailsDimensions (length × width × height) 43.2 × 37.6 × 71.7 cmApplication range ACApplication range HBPMBP application rangeNumber of phases 3Design: HermeticdB(A) @ 1 m 72Pressure line (inches) 1 3/8"Electronics includedRecommended crankcase heater 120Frequency 50–60 HzWeight 140Air flow rate 56.6 m³/hCooling capacity (kW) 52.2Refrigerant R134ARefrigerant R22Refrigerant R407CCapacity under operating conditions: 5°C evap. temp.; 50°C cond. temp.; 10 K suction superheat; 0 K subcooling for R-407C at 50 HzMax. operating current (A) 42Motor code TWDOil pre-filledOil quantity (l) 4.70Oil type: POEProduct family ZRSuction pipe (inches) 1 5/8"Compression type: ScrollSupply voltage 380–420 VSupply voltage 460VAdvantages and benefitsHigh reliability and efficiency thanks to the axial and radial flexibility of the scrollsLow noise and vibration levels ensure quiet operationOptimal system adaptation and cost reduction thanks to low overheatingHigh seasonal efficiency thanks to certified tandem and trio configurations Note:Oil: The compressor is pre-filled with oil at the factory.
