CMG’s HPD range of Ex d ‘flameproof’ motors are certified for use in Zone 1 hazardous locations. These motors are designed to contain any sparks within the motor without igniting external vapours. They incorporate features such as a robust cast iron construction and special terminal box to meet the stringent certification requirements.
The complete HPD range covers sizes 80 to 315, three phase 2, 4, 6 & 8 pole, with foot and flange mounting options.
The HPD range is specially designed and certified to IEC 60079.1 for use in a Zone 1, Group I & IIB, T4 class temperature, Ex d area. IEC certification number is IECEX TSA 10.0007X. ATEX certification number is Sira 0ATEX1001X.
HPD series motors are designed with the following parameters:
• Continuous duty (S1)
• Three phase 415 Volts, 50 Hz power supply
• Ambient temperatures up to 40°C
• Installation at altitudes up to 1000 metres
• Motors may be suitable for other operating parameters, enquire with CMG
Performance data is based on these parameters and may need adjustment for different conditions.
Motors can be manufactured for any supply between 100 and 1100 Volts and frequencies 40 Hz, 50 Hz or 60 Hz.
F class insulation, T4 surface temperature
HPD series motors have F class insulation and B class temperature rise. This design feature assures cool running of the motor. Certified Ex d T4 class motors have a maximum allowable surface temperature of 135°C. (T5) surface temperature class (maximum 100°C) is available on request (refer certificate, motor output will need to be derated).
Degree of protection
Level of enclosure protection for the HPD series is IP66.
