Hermetic scroll compressors ESP-200-2

Product catalog summary
Overview of the ELH7 Series: The ELH7 series by BITZER consists of horizontal scroll compressors designed for transport air conditioning, ideal for compact A/C units in trains and electric buses. Models range from 7.5 to 15 HP and are compatible with refrigerants R134a, R407C, and R22.
Technical Features: These compressors feature spirals with equal temperature through a patented cooling process, ensuring optimal alignment and minimal leakage. They offer high capacity and efficiency due to optimized spiral geometry and motor efficiency. The design is robust, with controlled spiral pressure and reliable oil supply via centrifugal lubrication.
Design and Installation: The compressors have a suction gas-cooled motor, low sound and vibration levels, and require minimal space, facilitating easy installation. They are fully hermetic with a welded shell and include a terminal box with IP54 protection.
Working Principle: The compressors operate with a moving spiral within a stationary spiral, creating compression chambers that compress the refrigerant gas, which is then discharged at high pressure through a muffler and check valve to the condenser.
Application Limits: Limits are based on a 20°C suction gas temperature, with specific parameters for refrigerants R134a, R407C, and R22, based on dew point conditions.
Performance Data: Based on the European Standard EN 12900 at 50 Hz operation, performance data considers evaporating and condensing temperatures based on dew point conditions, affecting cooling capacity and efficiency values. Data excludes liquid subcooling.
Model Designation: Model codes indicate scroll type, refrigerant compatibility, series, displacement, ester oil charge, and motor code. Variants with direct brazing connections are available.
Special Equipment: Options include oil heaters, shut-off valves, discharge gas temperature sensors, ester oil charge, and motors with special voltages.
Technical Specifications: Detailed specifications for models ELH725, ELH730, ELH736 using refrigerants R407C and R22 include cooling capacity and power consumption data across evaporation temperatures from 12.5°C to -15°C, for condensing temperatures of 30°C, 40°C, and 50°C.
Refrigerant and Oil Requirements: For R407C, polyolester oil BSE55 is required, while for R22, oil B5.2 is necessary. Saturated suction and discharge temperatures are based on dew point values according to EN 12900, with a maximum suction superheat of 10 K.
Technical Data: Includes compressor displacement, oil charge, weight, and pipe connections, as well as electrical data such as maximum operating amps, power consumption, and starting current.
Dimensional Drawings: Provides dimensional drawings and connection positions, including high and low-pressure connections and suction and discharge gas lines.
Additional Notes: Conversion factors for different voltages are provided, and options for oil heaters are mentioned. Other voltages and electrical supplies are available upon request.

Leistungsangaben Leistungsdaten basieren auf der europäischen Norm EN 12900 und 50 HzBetrieb. Die Verdampfungs- und Verflüssigungstemperaturen beziehen sich darin auf „Taupunktwerte“ (Sattdampf-Bedingungen). Bei zeotropen Gemischen, wie R407C, verändern sich dadurch die Bezugsparameter (Drucklagen, Flüssigkeitstemperaturen) gegenüber bisher üblicherweise auf „Mitteltemperaturen“ bezogene Daten. Als Konsequenz ergeben sich (zahlenmäßig) geringere Werte für Kälteleistung und Leistungszahl. Alle Daten sind ohne FlüssigkeitsUnterkühlung dokumentiert. Basierend auf EN 12900 ergeben sich dadurch deutliche...
