The PEAK Final Charge Global formulation is built to address the rigorous cooling requirements found in commercial and heavily loaded van applications, keeping temperatures stable during intensive stop-and-go routes or long highway hauls.

The inclusion of robust heat transfer properties ensures that modern emission-control components, such as EGR and SCR systems, operate within safe thermal thresholds. Furthermore, its versatile composition allows it to be mixed with other coolants when necessary, provided contamination levels remain below 25 percent to preserve optimal corrosion protection.
