Atlas Copco TC54S-4240-0450-81
Product Introduction:
The TC54S is the larger frame variant within the TC Standard series. It delivers the same 42.4 m³/min FAD as the TC52S but is built on the TC54 chassis, providing a larger oil sump, higher thermal mass, and enhanced durability for demanding duty cycles. The “0450” designation indicates a maximum working pressure of 50 bar (5,000 kPa / 725 psi), making it suitable for high-pressure applications. Voltage code “81” = 400V / 50Hz / 3-phase.

Material Composition:
- Rotor Housing: Cast iron (GG25)
- Rotors: Atomized alloy steel, 50 HRC
- High-Pressure Components: Reinforced steel for 50 bar rating (valves, piping, separator rated to 50 bar)
- Cooler: Aluminum plate-fin, high-pressure rated
- Tank: Carbon steel S235JR, tested to 50 bar
Structural Features:
- TC54 frame with reinforced baseplate
- Larger oil reservoir for extended thermal stability
- Heavy-duty belt drive system (B-section or C-section belts)
- Full canopy with acoustic insulation
- High-pressure rated safety valve set at 52.5 bar
Working Principle:
Identical to TC52S — two helical rotors compress air with oil injection. The 50 bar variant uses reinforced internals throughout the compression train, oil separator, and discharge piping to safely contain pressures up to 50 bar.
Key Advantages:
- 50 bar maximum pressure — eliminates need for a secondary booster in many applications
- TC54 frame provides superior thermal management for continuous operation
- Higher motor power (75 kW) ensures stable performance at full pressure
- Same Elektronikon Mk5 connectivity as the entire TC range
Applicable Industries:
Petrochemical, high-pressure pneumatic tools, paint spraying, PET blowing, laser cutting assist gas, CNG filling, fire-fighting air supply.
Installation Requirements:
- Indoor, well-ventilated space with minimum 2.0 m clearance
- Ambient temperature: 0°C to +45°C
- Floor load capacity: 1,800 kg
- Electrical: 400V/50Hz/3-phase, 160A circuit breaker
- High-pressure piping downstream must be rated to 50 bar minimum
Usage Notes:
- No dryer included — install downstream dryer rated for 50 bar inlet
- Oil: Atlas Copco Roto-Inject Fluid, change every 4,000 hours
- High-pressure safety valve inspection: annually
- Do not exceed 50 bar — the controller will shut down at 52.5 bar
