GT Expansion Tanks
Available in different sizes from 8 liters to 3000 liters, GT tanks are suitable for vertical installation. GT tanks from 24 to 80 liters can be installed both vertically and horizontally.
A non-toxic butyl rubber diaphragm in GT-H tanks divides the tank chamber into two chambers. The upper chamber contains compressed nitrogen. The lower chamber is lined with polypropylene (PP) and filled with water from the pump.
GT-D tanks are double diaphragm.
GT-U tanks, on the other hand, have a non-toxic butyl rubber replaceable inner tube wrapped in compressed nitrogen. The inner tube is the only part in contact with the liquid.
