Thermostat

Specified for maintenance teams seeking a dependable alternative spare part, the Thermostat (OEM 550 557 78) is a high-quality aftermarket component for compatible rock drilling and mining equipment within the compressor system. It monitors or regulates compressor temperature so the system can respond at the specified thermal operating point. Typical compatible references in the supplied list include DD311, DD311-40 and DD320 S.

For long-term reliability, the part is exposed to heat cycling, vibration, oil-system exposure and changing ambient conditions. Its temperature-sensitive operating element and connection geometry are selected to provide repeatable response in the compressor control circuit. Correct temperature regulation supports efficient warm-up, stable lubrication conditions and protection against abnormal thermal operation.
