Setup A: Worst Case Typical installation. The actuator is in an enclosed environment with very little cooling. No insulation on pipe nor venting. Setup B: Good To insulate the pipe will drastically reduce ambient temperature at the actuator level. Easy to accomplish and low cost. Setup C: Best of all Combination of insulation and extra vent added. Not always easy to accomplish. Ambient temperature will not be an issue. Note: Spartan Actuator uses a high temperature resistant …
