Hi, I am a Refrigeration Engineer from Indonesia.

Eg is sold with correct inhibitors either for steel, copper or for aluminium.
Antifreeze for cars is inhibited for aluminium.
Antifreeze for HVAC is inhibited for steel and copper.
Contact DOW chemicals or other suppliers for the correct antifreeze inhibitors and trade name.

Why use ethylene glycol? Its deterimental to the environment. Use propylene glycol, its safe and not much more in cost than the EG.
