Product Overview

HFCC-LEC-35 is a custom-designed efficient coolant with low conductivity tailored specifically for the unique designs and operating conditions of fuel cell systems. It features a proprietary formula that specifically inhibits ion leaching. The coolant is composed of ethylene glycol, deionized water, and a non-ionic corrosion inhibitor that undergoes a customized reaction and purification process. This results in exceptionally low conductivity, enabling efficient heat dissipation while simultaneously forming a protective film inside the cooling system. This film provides unmatched protection for both metal and non-metal components, achieving ultra-long service life with a single fill-up.

Product Advantages
