Compressor shutdown on Code 35 — High 3rd-Stage Scrubber Liquid Level. The FW Murphy TTD shutdown panel received a high-level signal and stopped the engine-driven reciprocating compressor. I inspected the third-stage scrubber, sight glass, and liquid-level shutdown switch/float assembly to locate the problem. One small safety device can shut down the entire compressor package. 🔧⚙️#ACFieldAndRanchServicesLLC #Oilfield #GasCompressor #ReciprocatingCompressor #Scrubber
