AEG 140CFA04000

Product Name: Hermetic Reciprocating Compressor
Model Series: 140CFA Series — Refrigeration Compressor
Applicable Products: AEG Refrigerators, Freezers, Wine Coolers, Built-in Cooling Appliances

Product Description:
The AEG 140CFA04000 is a hermetic reciprocating compressor used in AEG and Electrolux household refrigeration appliances. It is a R600a (isobutane) eco-friendly refrigerant compressor designed for high energy efficiency (A++/A+++ rated appliances). It provides the mechanical compression cycle that drives the vapor-compression refrigeration system.

Detailed content

Technical Specifications:

  • Part Number: 140CFA04000
  • Compressor Type: Hermetic reciprocating, single cylinder
  • Refrigerant: R600a (Isobutane) — 40g – 60g charge
  • Rated Voltage: 220–240V AC, 50Hz
  • Rated Input Power: 75W – 120W
  • Displacement: 9.8 – 11.2 cm³/rev
  • Operating Pressure: Suction 0.15 – 0.45 MPa / Discharge 1.2 – 2.0 MPa
  • Rotation Speed: 2850 – 3450 RPM
  • Lubricant: POE (Polyol Ester) oil — miscible with R600a
  • Noise Level: ≤ 42 dB(A)
  • Weight: 8.5 – 11.0 kg
  • Insulation Class: Class F (155°C)

Materials:

  • Shell: Welded steel (DC04 cold-rolled steel)
  • Cylinder: Cast iron or aluminum alloy
  • Valves: Spring steel (SUS302) with PEEK reed valve plates
  • Crankshaft/Connecting Rod: Carbon steel, nitrided surface
  • Motor Windings: Copper, Class F enamel insulation

Working Principle:
The compressor operates on the vapor-compression cycle: low-pressure refrigerant gas enters the suction port → piston compresses the gas → high-pressure gas exits through the discharge valve → gas flows to the condenser → after heat rejection, liquid refrigerant passes through the expansion valve → evaporator absorbs heat from the cabinet → low-pressure gas returns to compressor suction.

Advantages:

  • Ultra-low noise — optimized crankshaft balance and rubber mounting
  • R600a refrigerant — zero ODP, GWP = 3 (environmentally superior to R134a)
  • High COP (Coefficient of Performance) — contributes to A+++ energy rating
  • Long service life — hermetic seal prevents refrigerant leakage

Installation Requirements:

  • Must be installed in a well-ventilated compartment (minimum 10L air space around compressor)
  • Vibration isolators mandatory — use original rubber mounts
  • Electrical connection via PTC starter + thermal overload protector
  • Refrigerant circuit must be evacuated and charged by certified technician
