Advancing Safety, Performance & Efficiency

At HR Auto-solutions, innovation drives every design, component, and system we create. Our commitment to engineering excellence ensures that each product — from refuelling assemblies to interlock systems — is built with advanced technology, superior materials, and deep industry insight. We continuously evolve to meet the modern demands of aviation and industrial fuelling operations, where precision and safety are non-negotiable.

Built for Performance and Safety
Our components form the core of refueling trucks, hydrant dispensers, and bulk fuel management systems. Every design goes through rigorous testing, validation, and performance calibration to meet international safety and operational standards.
We integrate mechanical strength, hydraulic precision, and electronic intelligence to ensure smooth, leak-free, and automated fueling operations.

Our Product Line

  • Hose Reel
    Heavy-duty, high-pressure hose reels engineered for smooth operation, easy retraction, and long service life.            Features: corrosion-resistant build, hydraulic assist, and anti-leak coupling design.
  • Swivel Joint
    Precision-machined swivel joints designed for leak-free rotation and reduced wear under high-pressure fuel transfer.
  • Three Lug Adapter
    Aviation-standard three-lug couplings providing tight, secure connections between hose ends and refuelling nozzles.
  • FDF Valve (3 Models)                                                                                  Fast-acting FDF valves designed for controlled fuel discharge, high flow rate, and safety under dynamic pressure conditions.
  • EMCO Type Manhole Cover                                                                Heavy-duty, pressure-tested manhole cover ensuring secure sealing, vapor containment, and easy access for maintenance.
  • Water Detection Sensor                                                                          High-sensitivity sensors designed to detect the presence of water in fuel, preventing contamination and ensuring fuel purity.
  • High DP Switch                                                                                  Differential pressure switches for monitoring filtration systems and maintaining optimal flow and safety parameters.
  • Deadman Timer System
    Safety-critical automatic shutdown system ensuring fuelling stops instantly if the operator becomes inactive.
  • Water Detection System
    Integrated solution combining sensors and indicators to continuously monitor fuel quality during transfer.
  • Annunciator                                                                                              Digital and analog annunciator panels for real-time visual and audible status indication during refuelling operations.
  • Close Circuit Sampler (3 Models)                                                Closed sampling systems designed to draw fuel samples without exposure to air — maintaining integrity and contamination-free results.
  • Remote Engine Throttle                                                                Precision control system enabling remote operation of refuelling truck engines during fuelling sequences.
  • PLC Integrated Interlock System                                          Advanced programmable logic-based system providing operational interlocks for maximum safety and automation.
  • Relay Integration Interlock System                                  Electromechanical interlock solution ensuring secure operation and sequence control across fuel transfer systems.
