FRASCOLD reciprocating semi-hermetic compressors General information Frascold produces a wide range of semi-hermetic reciprocating single- and two-stage compressors with displacement range from 4 to 240 m3/h at 50Hz and electrical ratings from 0.50 to 80 HP. Suitable for conventional HFC-based , new low-GWP, HFO and natural refrigerants. The compressors are suitable for use in a wide range of retail and industrial cooling applications, process chillers, air conditioning and heat pumps; in single, multi-compressor systems and cascade systems. A wide range of accessories broadens their application...

FRASCOLD reciprocating semi-hermetic compressors Protection of compressors series A - B – D All models are supplied with protection consisting of a chain of PTC thermistors inserted in the electric motor stator and connected to the INT69 electronic control module inside the electrical box. The INT69 devices is triggered and stops the compressor in the event of thermal overload due to electric motor or mechanical issues. Protection of compressors series Q - S - V - Z - W with the new Diagnose technology Frascold integrates the Diagnose technology on semi-hermetic reciprocating compressors, which...

FRASCOLD reciprocating semi-hermetic compressors Capacity control with RSH system The cooling load of many applications may be extremely variable at different times and cooling systems must adapt to this variability. However, there is a limit in the number of admissible hour cycles for the compressor and a minimum operation time to be complied with. It is obvious that complying with these limits and adapting to the required cooling load result in an operating compromise that is not always the most efficient one. In general, the compressor’s functional limits described above set the maximum and...

FRASCOLD reciprocating semi-hermetic compressors Kriwan Diagnose multifunctional device INT69 ®Diagnose and INT69TML ®Diagnose Kriwan Diagnose devices are a further development of compressors’ protection units. The Diagnose technology is not only limited to protecting the compressor, but also offers diagnosis and system optimisation features; providing detailed information to technicians in order to promptly diagnose any plant problems; it even makes it possible to prevent malfunctioning before it occurs thanks to data analysis. The additional protection features help extending the compressor’s...

FRASCOLD reciprocating semi-hermetic compressors ATEX compressors Within the European Union, mechanical and electrical equipment used in explosive atmosphere must comply with ATEX requirements. Frascold has been among the first compressor manufacturers to offer a comprehensive range of ATEX-certified compressors. All ATEX compressors produced by Frascold are approved also for use with hydrocarbons R290 and R1270. Contact Frascold for use with other conventional hydrocarbons. Construction concepts ATEX compressors are designed in accordance with safety requirements set forth for use in hazardous...
