Orifice Tube Section Analysis
The pictures below and accompanying S E M analysis give visual evidence of the large amount debris filtered out of the untreated system (B) during a simulated 36,000 mile test cycle. For comparison purposes a tube from new evaporator (A) is also shown along with the evaporator section of the treated system (C).
