Insulation & Heat Dissipation

  • Class F is encapsulated Nylon coil. Class H is encapsulated Phenolic coil (types H1 and H2 are open wound (not encapsulated)).
  • Consider the environment (see IP ratings). If the environment is higher than the IP rating of the coil takes measures to protect (ie shelter from the rain or heavy hosing).
  • Note that the coil must still be able to vent the excess heat (do not lag or place coil in a sealed housing without ventilation. This will cause the coil to heat stress and fail).
  • Coils can tolerate higher than rated ambient temperatures when energized for short periods of time. This time varies depending on the coil wattage, ambient and media temperatures.
  • Use the Power Saving plug (see website) to reduce the operating heat in process coils (only available in 240v Ac and 24v DC) that are energised for long periods of time in high ambient temperature applications.
  • Other considerations are Power, Media temperature and AC ripple in DC power supplies (they should be regulated and smoothed DC supply). Also the valve elastomer selected for specific chemical and media applications must be taken into consideration if operating in a high ambient environment.
  • Another consideration type H1 and H2 coils are open wound (IP54) and have the ability to dissipate heat quicker than the encapsulated coils (IP65) even though they are all Class H rated. Their lower IP rating must be taken into account.
  • Coils used in Process Systems valves are designed and tested for continuous service 100% duty cycle (ED100%). 
  • They all meet the IEC 216 thermal endurance specifications when factory tested. Specific field applications are outside of our control and the site engineer must test to suit the environment.

F 155°C 50°C
H encapsulated 180°C 50°C
