1 2-pole design Semi-hermetic compressors with 2-pole drive motor for mains voltages of Hz New: Now for Hz mains voltage

2 Baureihe HG series HG 2-pole 2-polig - t a glance t a glance Based on our compressors of the luscom series with its outstanding advantages and features, Bock offers already for some time a compressor version with 2-pole drive This compressor version makes mains voltages of Hz possible and therefore a corresponding higher refrigerating capacity compared to an operation with Hz mains voltage. This increase in the maximum possible compressor capacity can be realised through the use of a special valve plate system. The socalled Bock K-valve plate, which was developed by Bock especially for mobile applications, is already used thousands of times in the area of bus air-conditioning and sets the international standard for quality and reliability. Special features --High performance with 2-pole drive motor (up to rpm) -- With oil pump lubrication as standard --Bock K-valve plate --lso available in aluminium lightweight design (option) (ca. % weight savings) --vailable with terminal box with reduced height rpm rpm Hz Hz Type key HG 2-pole HG34 / 35-2 S K vailable models Design luminium design Motor variant 4) Number of poles Swept volume luscom 3) Number of cylinders 3) Size ster oil filling 2) Series ) ) HG = Hermetic Gas-cooled (suction gas-cooled) 2) = ster oil filling (HFC refrigerants e.g. R34a, R7C) 3) = dditional declaration for luscom compressors 4) S = More powerful motor e.g. air-conditioning applications Displacement Hz (3.480 rpm) HG34/35-2 K 65,6 m 3 /h HG34/35-2 K 65,6 m 3 /h HG34/35-2 S K 65,6 m 3 /h HG34/35-2 S K 65,6 m 3 /h HG34/380-2 K 79,3 m 3 /h HG34/380-2 K 79,3 m 3 /h The K-design for Hz Design for Hz The Bock K-valve plate with ring fins for higher loads --Valve design, tried and trusted all over the world, with onesided fixed finger reed valves, suction and pressure side -- Valve made out of high quality, impact resistant spring steel 2 I

Compressor application limits should not be chosen for design purposes or continuous operation. For operation with frequency converter: Minimum frequency = 5 Hz Maximum frequency = Hz erformance data The performance data for R34a are based on N 2900 at Hz power supply frequency. This signifies: 20 C suction gas temperature without liquid subcooling. This results in significant differences compared to specifications with liquid undercooling and/or suction-gas temperatures. erformance data for other operating points, see Bock software. Calculations Calculating the maximum possible frequency of the compressor under specific operating conditions: The following calculation is used to obtain the maximum possible frequency at the selected operating point: Calculating the corresponding refrigerating capacity: Refrigeration capacity can be determined as a function of frequency from the following calculation: f max = max x Hz e o operation = f operation x 0 Hz Hz f max max = maximum permissible frequency [Hz] = maximum power consumption [kw] (see technical data, compressors) o operation = refrigerating capacity at the chosen operating point [W] f operation = frequency at the chosen operating point [Hz] e = power consumption at the operating point at Hz [kw] (see performance data, compressors) o Hz = refrigerating capacity at the operating point at Hz [W] (see performance data, compressors) i s a rule, the maximum permissible power consumption of the compressor max must not be exceeded. The maximum permissible frequency is always restricted in case of high evaporation temperatures associated with high condensing pressures with refrigerant R7C. I 3
