The system’s expanded water (fully compatible with water/glycol mixtures) is contained in a heavy-duty bladder preventing tank corrosion and waterlogging problems.  If the bladder extends beyond the normal movement, Wessguard monitor will activate an audible and LED alarm to notify maintenance staff of a potential system issue.  In the case of compromised bladder integrity, water level will rise to activate the alarm.
