Air Cooled Quick Frozen Spiral Freezer Bitzer Compressor Racks

1. Brief Introduction - Condensing Unit 1) It adopts the world-famous Bitzer ECOLINE series semi-hermetic piston compressor, offering high reliability and efficiency. 2) Multi compressors are parallel connected to provide bigger capacity sharing same discharge pipe, suction pipe, condenser, liquid receiver, etc. 3) Compact design for easy installation and small installation size. 4) Multi-stage energy adjustments according to cooling capacity to save operation cost. 5) Can meet medium and low temperature requirements. 6) Other kinds of power supply not mentioned in the specification is optional, such as 220/440/460V-3Phase-60Hz. 7) Application: Meat, vegetable, fruit cold storage, food prepare workshop, chemical cold room, medicine cold room, freezer tunnel, blast freezer, walk-in freezer, supermarket food display cabinets, fresh keeping, etc. 2. Characteristics 2.1 Variety of Options Piston type 2 compressor parallel unit Piston type 3 compressor parallel unit Piston type 4 compressor parallel unit Adopted to multiple refrigerants such as R404a, R507, R407C, R22. 2.2 Stable & Reliable The units are equipped with world-famous brand high-quality compressors and components, following the latest design, the perfect combination provides a safe and reliable system. The unit comes standard with a controller that can effectively avoid turning on/off the motor frequently as well as safety protection modules including the following: Phase loss protector, Inverted sequence, Overvoltage protector, Undervoltage protector, Oil pressure, High pressure, Low pressure, Motor overload. 2.3 High Efficiency & Energy Saving Because of a huge demand difference between seasons for refrigerating capacity, the unit must have a high level control for capacity, so that the unit can keep running under high efficiency mode. The average parallel unit efficiency, according to different refrigeration system is 30% higher than single compressor unit. Using multiple compressor parallel units can provide a multiple energy level control, the refrigeration output can be dynamically allocated more smoothly according to actual situation. With high efficiency oil separator, only a small amount of lubricating oil enters the system, this largely brings up the heat exchanging efficiency. 2.4 Compact & Nimble Components such as compressor, reservoir, gas-liquid separator, oil separator, electrical control equipment, etc., are all centralized, making sure every inch of the space is fully used. The unit has a compact structure, the space saved during assembly can provide more space for commercial use, benefiting the end user with extra profit. 3.
