The Future of Coolant

Future coolant technology ( Read Less )

Currently, most coolants use either ethylene glycol or propylene glycol as a base. The difference between the two is that ethylene glycol, while less expensive, is considered more toxic than propylene glycol. While these traditional coolant types are still the industry standard, new technologies are emerging.

Renewable glycol-based coolants ( Read Less )

Although its relatively environmentally friendly, conventional propylene glycol comes from a non-renewable resource. But that’s changing. Now, propylene glycol can be made from both biodiesel and corn. HD Expert uses these resources to provide a more ecological option for our customers.

Ethylene glycol can also be made safer for the environment. It’s able to be recycled through processes like distillation and reverse osmosis. HD Expert produces its own redistilled ethylene glycol at a facility in Quebec, Canada. This redistilled ethylene glycol meets the highest industry standards.

Additional coolant types ( Read Less )

Other coolant types are beginning to pop up as well. Recently, interest has risen in glycerin and 1,3 propanediol (PDO) as coolant base fluids. Glycerin is of interest because it can be made from biodiesel. Likewise, PDO is an isomer of propylene glycol that can be made from natural products. Early research indicates PDO may even perform better – and be less toxic – than propylene glycol.

Taking care of our planet is a task everyone shares. HD Expert is contributing by developing new coolant technology for an ever-changing world.
