Glycerin for RO Membrane Freeze Protection & Lubrication

Glycerin Lubricant & RO Membrane Freezing Protection

To winterize an RO system and protect RO membranes from damage due to freezing, preserve the membranes in a solution of 2% AM-88 and 20% AM-225. The glycerin will not prevent freezing below 32°F, but the crystals are soft and the membrane is not damaged.
