Questions and answers

Why use glycol in a hot climate where water never freezes?

In Oman the main reasons are corrosion control, pH buffering and slowing microbial growth. Inhibited glycol carries an inhibitor package that protects steel, copper and aluminium, and loops below 25% glycol are prone to microbial growth and glycol breakdown. It also protects low-temperature process loops and units exposed to cold desert nights.

What percentage of glycol should be in a closed-loop HVAC system?

Typical working dilution is 25% to 65% glycol by volume, balance purified water. Solutions below 25 to 30% may not give adequate corrosion protection. Choose a freeze point at least 3°C (5°F) below the lowest expected ambient or operating temperature, and do not go below 25% for inhibitor and biostatic protection.

Should I use ethylene glycol or propylene glycol at a rig camp?

Ethylene glycol transfers heat better and has lower viscosity, but it is moderately toxic. Propylene glycol is much less toxic and is the choice wherever incidental contact with people, food or drinking water is possible. At camps where kitchens, potable water and cabins sit near the HVAC plant, we recommend the propylene (MPG) grade.

Can I use automotive antifreeze in an HVAC chiller?

No. Automotive antifreeze is unsuitable for HVAC and industrial loops because its high silicate inhibitor levels can foul heat exchangers and cause pump seal failures. Use an industrially inhibited glycol made for closed-loop HVAC, and do not mix glycol types or brands in the same loop.

How do you test glycol concentration in an HVAC system?

A refractometer is the practical field check for glycol percentage. Check pH as well, and send samples for periodic lab analysis of reserve alkalinity, inhibitor level and contamination. Warning signs of degradation are pH falling below about 8, a sharp or septic odour, rising iron and copper, and microbial growth.
