U23D Solar Linear Actuator for Desert CSP Tower Heliostats
Temperature and Operating-Cycle Selection for CSP Projects
The U23D is a 24V DC heliostat actuator with a specified ambient temperature range of -40°C to +70°C. For desert CSP projects, selection should consider site temperature together with movement frequency, working load and installation position.
-40°C Specified Lower Ambient Limit
+70°C Specified Upper Ambient Limit
24V DC Rated Voltage
IP66 Protection Class
Define the Site Conditions First
| Project Input | Information to Provide |
|---|
| Temperature Profile | Expected minimum and maximum ambient temperatures, including seasonal extremes |
| Actuator Location | Mounting position, direct sun exposure and any nearby heat sources |
| Movement Schedule | Travel per adjustment, movement frequency and rest periods |
| Operating Requirement | Push/pull load and required speed during movement; static load when stationary |
Temperature range is not a continuous-running rating. Confirm the required load, speed and operating cycle for the project configuration.
U23D Performance Reference
| Parameter | Specification |
|---|
| Application | Solar Tower Heliostat Tracking |
| Ambient Temperature | -40°C to +70°C |
| Rated Voltage | 24V DC |
| Rated Push & Pull Load | 40,000N |
| Maximum Static Load | 55,000N |
| No-Load Speed | 0.125–1.5mm/s |
| Code A Rated Speed | 1.0mm/s |
| Protection Class | IP66 |
| Minimum Installation Dimension | 200mm ±2mm; confirm against the selected configuration drawing |
| Stroke | S ±2mm; project-specific |
40,000N is the rated operating load; 55,000N is the maximum static load. The no-load speed range does not specify travel speed under working load.
Match Travel with the Movement Schedule
Provide the travel needed for each tracking adjustment and any longer positioning movement. Required travel and speed determine movement time, which should be reviewed alongside rest periods and site temperature.
Use the heliostat drawing to confirm mounting points and stroke. A change in mounting geometry can change both travel and actuator load.
