Description
SUPER POLAR GRADE No-Freeze Concentrate – Propylene Glycol
Super Polar Grade No-Freeze Concentrate is pure high grade propylene glycol with special anti-corrosion inhibitors and color indicators. No-Freeze products contain propylene glycol because propylene glycol is the only material safe for most ordinary anti-freeze requirements. This is because propylene glycol is non-toxic and non irritation and eliminates the possibility of contamination domestic, potable water with toxic materials.
Best way to test freeze protection is with a refractormeter. Refractometers are extremely accurate, easy to use and effective, regardless of solution colors, dyes and temperature.
No-Freeze lubricates pumps, valves and moving parts and will not harm plastic or rubber seals, diaphragms or washers. No-Freeze will not support bacterial growth.
New Systems should be designed with an air cushion as much as 20% larger then required for water only systems to allow for low and high temperature expansions. In order to avoid a loss in heat transfer efficiency, new systems should be sized for increased flow rate to compensate for lower heat of no-freeze solutions and, therefore, have no efficiency loss.
