Tamrotor Marine Compressor E6 CC1056758

Tamrotor Marine Compressor E6 (Part Code: CC1056758) Screw Air Compressor

The Tamrotor Marine Compressor E6 (Part Code: CC1056758) is an oil-injected rotary screw air compressor engineered for continuous marine, offshore, and industrial duty cycles. Built to handle harsh engine room ambient temperatures up to +55°C, high vibration, and severe pitch/roll conditions, the E6 platform delivers dependable service and control air for commercial vessels, platform supply vessels (PSVs), workboats, and offshore rigs.

Technical Details

Features

1. Advanced 5:6 Asymmetric Rotor Profile: Precision-ground helical rotors maximize volumetric displacement while lowering inter-lobe back-leakage, reducing power consumption per cubic meter of delivered air.
2. Marine-Duty Heavy-Bearing Assembly: Incorporates matched angular contact ball bearings and cylindrical roller bearings designed to endure axial dynamic thrust and constant marine vibrational loads.
3. Integrated Thermostatic Bypass & Minimum Pressure Valve: Guarantees rapid warm-up to prevent internal moisture condensation in high-humidity engine rooms, keeping oil injection temperatures strictly above dew point.
4. High Roll/Pitch Tolerant Lube Circuit: Modified sump baffles and deep suction pick-up prevent oil foaming, cavitating, or starvation during heavy sea states (compliant with IACS dynamic angles up to 22.5°).
5. Low Maintenance Spin-On Modular Filtration: Simplified spin-on cartridge configurations for both full-flow oil filtration and coalescing air/oil separation allow sub-30-minute turnarounds during offshore maintenance intervals.

Marine Applications

• Shipboard Service & Working Air: Supplies continuous low-pressure compressed air across machinery rooms, deck connections, workshop tool air manifolds, and sea chest blowout lines.
• Pneumatic Automation & Control: Drives pneumatic actuators, remote quick-closing fuel shutoff valves, exhaust valve booster circuits, and 3-way thermostatic mixing valves.
• Instrumentation & Deck Purge: Serves as dedicated feed air for pneumatic tank level gauging systems (bubbler systems), radar mast air horns, and cargo hold air-purge circuits.
• Nitrogen Generator & Membrane Feed: Delivers constant, stable mass flow to on-board nitrogen membrane systems for inert gas blanketing on chemical and offshore support vessels.
• Marine Sanitation & Sewage Plant Aeration: Supplies low-pressure, continuous aeration air for biological sewage treatment units (STP) requiring steady volumetric flow without cyclical pulsation.

Frequently Asked Questions

What does part code CC1056758 refer to on the Tamrotor E6?

Part code CC1056758 designates a specific OEM assembly configuration of the Tamrotor E6 rotary screw air end. This includes the designated shaft taper/keyway, casting porting (BSPP/NPT), internal clearance class, and seal materials tailored for marine auxiliary compressor packages.

Can the Tamrotor E6 air end be driven by both belt and direct couplings?

Yes. The Tamrotor E6 is engineered with reinforced cylindrical roller bearings at the drive end capable of absorbing radial side loads from multi-groove V-belts or poly-V drive belts. It is equally adaptable to direct drive installations via bellhousing flange adapters and flexible shaft couplings.

How often should the bearings and seals be replaced on this unit?

Under standard marine engine room conditions with high-grade synthetic oil, the mechanical shaft seal assembly should be renewed every 8,000 operating hours or 2 years. A full bearing replacement and overhaul cycle is recommended between 20,000 and 24,000 operating hours, or immediately if vibration analysis reveals harmonic anomalies on outer race pass frequencies.

How do I troubleshoot high discharge air temperature on a Tamrotor E6?

First, verify oil level in the sight glass while the compressor is running under full load. Second, check the thermostatic mixing valve element to ensure it is not stuck in bypass mode. Third, check the oil cooler differential pressure and clean any oily scale or sea-salt fouling across the cooler matrix. Finally, verify that the scavenge line restrictor is clear and the air intake filter is clean.

What is the acceptable oil carryover rate in the discharge air?

With an intact, properly seated OEM coalescing separator element, residual oil carryover should remain below 3 ppm (3 mg/m³). If oil consumption climbs significantly or downstream air lines exhibit pooling lubricant, replace the separator element and inspect the scavenge line one-way check valve for debris.

Is the CC1056758 compatible with variable speed drive (VSD) operation?

Yes. Provided the motor and drive inverter maintain rotor speeds strictly within the certified 1,450 to 6,000 RPM range, the E6 functions efficiently in variable delivery systems. Speeds below the minimum limit must be locked out in the inverter parameters to prevent inadequate lubrication and rotor thermal growth.
