Screw Style Chiller

XC-XXS series screw style chillers host used German BITZER semi-hermetic screw compressors have outstanding technical characteristics in single-compressor and two-compressor models. It is applicable to R22, R407, R134a and other refrigerants. High efficiency horizontal shell and tube condenser and evaporator have "BR1" state permission to create a pressure vessel, heat stability and maintenance convenience. An advanced micro-computer controller, a powerful, high-speed embedded microprocessor performance is much higher than similar products used in the single-chip machine.

Features
·Germany semi-hermetic screw compressors, bearing longevity will ensure long-term operation;
·Double-conditioning compressor energy, following customer demand, made adjustments to achieve energy-saving effects;
·Condenser and evaporator meet national needs, the highly efficient heat exchanger performance, and maintenance convenience;
·Controller dilate in good condition and can facilitate the expansion and upgrading of hardware and procedures;
·Watchdog technology to the micro-computer controller hardware components with self-diagnostic capabilities, automated troubleshooting:
·Equipped with the high stability of memory, storage capacity of 512K, procedures for interfacing to power outages and maintain data capacity, and also a substantial loss of data storage.
·Sieve Protection System, which allows for a unique auditorium, Sieve life span of 10 years or more;
·Inquiries can be functional fault by fault and statistics serial numbers of failures that occurred and to analyze the causes for failure to be improved;
·Actual temperature and can be checked at any time to check the changes in the set changes, in addition to an hourly and a one-day show on the temperature curve;
·Machine with remote control switches can be realized by a timer switch plane and weekly machine timer switch applications. Switching planes can be set up 3 per day;
·Switching to support multiple languages online.
