Kalymnos VRU Couplers (proximity)

KALYMNOS FUEL ENGINEERING presents its specially designed Vapour Recovery Unit (VRU) coupler, a critical component for the safe and environmentally compliant recovery of fuel vapours during refueling operations.

Purpose & Function
This coupler connects the fuel dispenser to the service station’s vapour recovery system. Its purpose is to effectively capture petrol vapours displaced from the tank during filling, preventing their release into the atmosphere and ensuring compliance with environmental regulations.

Key Design Features

• Robust One-Piece Construction: Integral coupler body made from aluminum casting EN AW-42000 for lightweight durability and corrosion resistance.
• Visual Flow Verification: Two side-mounted sight glasses for immediate and clear visual monitoring of flow and connection verification.
• Positive Seal Mechanism: Integrated clapper valve system ensuring a tight seal and preventing vapour leakage when the coupler is not in use. Includes:
  • Durable aluminum clapper assembly.
  • Pressure spring made of stainless steel AISI 302.
  • Sealing O-ring from FKM (Viton) for fuel compatibility.
• Connection & Compatibility: Features a female A5 4″ connection, the standard interface for vapour recovery systems, ensuring full compatibility with existing dispensers and station infrastructure.
