    1. General 1.1 Introduction of ATEX ATEX is an acronym of “Atmosphéochres Explosives” from French. This includes two European Union (EU) directives which regulate the manufacture, selection and usage of equipments in dangerous zone and has become a compulsory act between members of EU since July 2003.

    management system, and each product can reach the same standard as an EU model tested sample. According to different conditions of conformity assessment the appendix of ATEX 2014/34/EU also regulates corresponding QA requirements. The confirmation of requirement of the above mentioned QA system is supervised by EU designated authorities, and the so called QA system is not only the field covered by ISO 9001.

    In addition, Hanbell also offers 250W oil heater to keep adequate lubricant oil temperature for large external oil separator and applications in areas with low ambient temperature. Specification： 250W; 110V or 220V; IP 54; Outer diameter of cable: 6~8mm Note: If compressor is installed in low ambient temperature, it is recommended to insulate oil separator against cold ambience.

  • Page 31: Solenoid Valve

    Note: Before using oil drain valve, the compressor must be switched off and the refrigerant must be recovered completely to avoid dangerous leakage of refrigerant which threats the environment. 2.13 Solenoid valve Figure Solenoid valve Degree of protection IP 67 -40℃~+65℃...
  • Page 32 Percent voltage unbalance = 100 x NEMA states that poly-phase motors shall operate successfully under running conditions at rated load when voltage unbalance at the motor terminals does not exceed 1%. Furthermore, operation of a motor with over 5% unbalance is not recommended for it probably results in motor damage.

  • Page 33: Lubricants

    To solve this problem, use of oil heaters can warm up oil before starting. If the compressor operates under critical operating conditions, an extra oil cooler is required – please refer to Hanbell selection software for the required capacity and oil flow of the extra oil cooler. High-viscosity oil is recommended to apply in high operating conditions because high discharge temperature will make viscosity of oil lower.
