  • Page 8: Ignition Protection Concept

    2 | Product description 2.2 Ignition protection concept The compressor described in these instructions for assembly is suitable for use in device category 3 for explosive gas atmospheres up to temperature class T3 and explosion hazard subgroup IIB/IIC in accordance with Directive 2014/34/EU. The entire compressor, including motor, is perceived as technically tight and therefore does not need an ignition protection. To prevent ignition risk caused by working materials also during system malfunctions, all used working materials have to meet the requirements for the temperature class of the compressor. The surface temperature of the compressor may not exceed 80 % of the ignition temperature of the working material. For this reason all working materials need to have an auto-ignition temperature of > 250 °C. The scope of delivery of the standard compressor comprises a conductive paint finish, that is suitable for the use in explosion group IIC. If the compressor is delivered with the accessory "Offshore Paint Finish", the application is restricted to explosion group IIB.
  • Page 9 2 | Product description Accessories Heating elements for the compressors to protect against explosion risks are designed in the protection types increased safety (Ex d) and have to have to be mounted stationary at the designated areas in the compressor housing. The heating elements can be operated without temperature- and oil level control since the thermal type testing by the manufacturer verified that the heating elements prevent the exceeding of the temperature class of the compressor. The control has to be carried out in a way that the heating element can only be operated during shutdown of the compressor.

    3.2 Important information on the use of hydrocarbons Hydrocarbons (combustible refrigerants) may be used in the compressors named in the title only if all relevant and applicable regulations, standards and technical rules are followed. National safety regu- lations must be observed. In addition, we refer to the following applicable standards and regulations: EN 378, BGR500, TRBS 2152, EC Directives 1999/92/EC and 2014/34/EU. The compressor and the refrigeration system must be permanently equipped with clear, identical labels/plates (ISO 3864) that state that combustible refrigerants are used. This warning plate must be unremovably attached to the compressor. A hazard analysis in accordance with the Operational Safety Ordinance must be performed for the set-up location. Use and handling of the refrigeration system and compressor are to be governed in the explosion protection document. Installation, placement into operation, service and repair (as permitted by the manufacturer) may only be performed by personnel who have been specially trained on combustible refrigerants. If the compressor has to be removed from the system for inspection/maintenance/repair, the remaining refrigerant must be suctioned out and the compressor evacuated, filled with nitrogen (< 0.5 bar) and closed gas-tight. The compressor must be equipped with a tag that clearly states that the compressor was operated with combustible refrigerant (name the refrigerant). If the system contains combustible refrigerants or residues, extreme caution must be exercised when working on the compressor due to the danger of explosion. This applies especially for the use of fire, open flame or other ignition sources (e.g. electronic devices, mobile telephones, static charges, sparks, ...). During maintenance and repair, it must be noted that hydrocarbon residues may remain dissolved in the oil. In addition used dryers contain bottoms of the inflammable refrigerants. Flush the dryer with nitrogen and supply it to the recycling. It should be noted that the solubility of hydrocarbons in oil can be very high, especially at high suction pressures. A high-viscosity lubricant may be required, depending on the application and experience. The lubricant must be released for use by GEA. Depending on the application, a pump-down switch should also be added (e.g. when the refrigeration system is set up outside).

The INT69 EX2 trigger unit must be installed according to the wiring diagram. The hot gas sensors of the cylinder cover and the temperature sensors of the motor are observed by the electronic trigger unit INT69 EX2. In case of excess temperature in the motor winding and/or in the hot gas, the INT69 EX2 deactivates the motor contactor. Once cooled, it can be restarted only if the electronic lock of the output relay (terminals 1+2) is released by a mains reset > 5 sec. The INT69 EX2 fulfills the requirements of the IPL 1 (Ignition Prevention Level) as prescribed in the EN 80079-37 and has an appropriate EX identification. The unit trips when an overload or inadmissible operating conditions occur. Find and remedy the cause.
