Supplier's note

1. Technical Breakthroughs:

   • High-Performance Heating: The Pro Model’s 1500W output (50% higher than Base) enables rapid preheating in sub-zero conditions.
   • Corrosion Resistance: Aluminum alloy construction outperforms traditional steel by resisting rust in saltwater or chemical environments.
   • Universal Fitment: The Pro Model’s compatibility with all Cummins diesel engines eliminates the need for multiple part purchases.

2. Version Selection Guide:

   • Base Model: Ideal for light-duty applications (e.g., ISL engines in delivery trucks) where cost efficiency is prioritized.
   • Advanced Model: Best for medium-duty machinery (e.g., QSC engines in agricultural equipment) requiring broader engine compatibility.
   • Pro Model: Suited for heavy-duty operations (e.g., mining or offshore equipment) demanding extreme durability and universal fitment.

With the Pro Model’s industrial-grade durability, you can operate in corrosive marine environments while maintaining consistent performance. Pair its high heating capacity with the adjustable fin design to optimize heat distribution for faster engine startup.
