Atlas Copco TC52P-N4240041 080
Product Introduction:
The TC52P-N4240041-080 is the premium VSD variant of the TC52 frame, configured for 41 bar maximum working pressure, with no integrated dryer (“N”). The model code breaks down as: TC52P = TC52 Premium (VSD), N = no dryer, 4240 = 42.4 m³/min FAD, 041 = 41 bar max pressure, 080 = 400V / 50Hz / 3-phase electrical code. This is the highest-efficiency 41 bar compressor in the TC range, combining IE4 PM motor technology with high-pressure capability.

Material Composition:
- Rotor Housing: Cast iron GG25 — 41 bar rated
- Rotors: Atomized alloy steel, 50 HRC — high-compression-ratio geometry
- PM Motor: Neodymium permanent magnets, IE4 rated, 41 bar compatible insulation class
- Oil Separator: 41 bar rated, glass fiber coalescing
- High-Pressure Valves: 41 bar rated minimum pressure valve, safety valve (set at 43.05 bar)
- Cooler: Aluminum plate-fin, 41 bar rated
- Inverter: IP54 rated, 41 bar vibration-resistant mounting
Structural Features:
- TC52P chassis with VSD inverter integrated in canopy
- All pressure-wetted components rated to 41 bar
- Elektronikon Mk5 controller with VSD algorithm optimized for high-pressure operation
- Condensate drain with auto-timer
- Vibration-isolated PM motor mounting (PM motors have different vibration characteristics than IE3 motors)
- Sound-attenuated canopy with acoustic lining
Working Principle:
The PM VSD motor varies speed to maintain the set discharge pressure (up to 41 bar). At partial load, the compressor reduces speed, and because power scales with the cube of speed, energy savings are substantial. The high-pressure compression train uses a higher compression ratio rotor geometry and reinforced internals to safely achieve 41 bar. The Elektronikon Mk5 controller manages the VSD algorithm, pressure regulation, and all protection functions.
Key Advantages:
- IE4 PM motor + VSD = up to 35% energy savings vs. fixed-speed 41 bar compressor
- 41 bar capability in the most efficient TC variant available
- No dryer included — full flexibility to select dryer type
- Elektronikon Mk5 with remote monitoring (Elektronikon Connect)
- PM motor has zero rotor losses — highest electrical efficiency in the TC range
Applicable Industries:
PET blowing, high-pressure painting, CNG feed, fire-fighting, laser cutting, any facility needing 41 bar air with minimum energy cost.
Installation Requirements:
- Indoor, 1.5 m clearance all sides
- Ambient: 0°C to +45°C
- Floor load: 1,400 kg
- Electrical: 400V/50Hz/3-phase, 100A breaker (Code 080)
- All downstream piping, valves, and equipment rated to minimum 41 bar
- Separate dryer required — install refrigerated or desiccant dryer downstream
- Safety valve discharge pipe to safe location
Usage Notes:
- Oil: Atlas Copco Roto-Inject Fluid, change every 8,000 hours or 2 years (VSD extends oil life)
- Air filter: every 4,000 hours
- Oil separator: every 8,000 hours
- Desiccant dryer (if selected): media replacement every 3–5 years
- Refrigerated dryer (if selected): pre-filter every 4,000 hours
- PM motor requires no maintenance — no brushes, no slip rings, no excitation current
- Annual inspection of all 41 bar rated components (valves, separator, piping)
