Description

For sale is one (1) Siemens PE•21 PLUS AC induction motor, 75 HP, 575V, 3-phase, 1775 RPM, Frame 365TS, Part No. 30000838971, Serial H06TG0838971 1. 

The Siemens PE•21 PLUS is a Mill and Chemical Duty induction motor — a heavier-duty construction designation above standard TEFC motors, designed for demanding process environments involving shock loads, vibration, moisture, and chemical exposure. This is the specification typically selected for pumps, compressors, conveyors, and mixers in oil sands, mining, chemical, and heavy industrial applications.

Three features distinguish this motor from standard surplus offerings:

1. Mill and Chemical Duty ConstructionThe RGZESD type designation and "Mill and Chemical Duty Quality" nameplate designation indicate reinforced frame construction, enhanced bearing protection, and robust end-shield design suited for the most demanding industrial drive applications. This is not a standard commercial-duty motor.

2. Class I, Division 2 Certified (NEC 501-125(B))The motor carries a factory-fitted certification plate confirming it meets the National Electrical Code (2005) definition for motors permitted to be installed in Class 1, Division 2 hazardous locations. This certification is required for installation in areas where flammable gases or vapours may be present under abnormal conditions — standard in oil sands, upstream oil and gas, petrochemical, and refinery facilities.

3. NEMA Premium EfficiencyNominal efficiency of 94.1% — NEMA Premium certified. The 1.15 service factor provides additional thermal headroom for overload conditions.

The motor is equipped with a 120V / 130W space heater (leads H1–H2) for cold-climate condensation prevention during standby — standard specification for Alberta industrial installations.
