high efficient screw compressor

   


Name: High Efficient Screw Compressor

Brand: Hanbell /Bitzer

Original: Taiwan / Germany



high efficient falling film evaporator

Name: High Efficient Falling film Evaporator

Original: China


high efficient flooded evaporatorName: High Efficient Flooded  Evaporator

Original: China

 ●  EVAPORATOR: The evaporator (shell&tube) is single-pass on both the refrigerant and water sides for pure counterflow heat exchange and low refrigerant pressure drops.

 ●  CONDENSER: Shell & tube condenser with water flowing inside the tubes and refrigerant condensing outside. The bottom of the condenser is provided with subcoller section fo better refrigerant capacity. The tubes are enhanced for maximum heat transfer and rolled into steel tube sheet and sealed.

 ●  COMPRESSOR: Hanbell semi-hermetic compressor, screw type with gate-rotors made of carbon impregnated engineered composite material. The compressor has one or two slides managed by the unit microporcessor modulating the capacity from 100% down to 25%. An integrated high efficiency oil separator maximizes to the oil separation and standard start is Wye-Delta(Y-Δ) type.

   REFRIGERANT CIRCUIT: Each unit has one independent refrigerant circuit and includes: compressor with integrated oil separator, Expansion valve, Filter drier, Charging valves, Liquid line shut off valve, Sight glass with moisture indicator, High pressure switch, High pressure transducers, Low pressure transducers, Oil pressure transducer, Suction temperature sensor.  

 ●  ELECTRICAL: Control and power sections are located into the main electrical panel that is manufactured to  ensure protection against all weather conditions. The electrical is IP45 and intrnally protected with plexyglas panel against possible accidental contact with electrical component (IP20 when doors are open). The main panel doors are interlocked to the main switch(standard) in order to guarantee safe operation when the doors are open.

 ●  CONTROLLER: Siemens type. Providing monitoring and control functions required for an efficient and trouble free operation of the chiller. Sophisticated software with predictive logic selects the most energy efficient combination of compressor load and electronic expansion valve position keeping stable operating conditions and maximizing chiller efficiency and reliability.
