Aquatherm 500 gal. 6′ x 8′ Trough w/ 8 drink tubes
These highly insulated field-proven troughs provide dependable water access in extremely cold conditions without an external heat source. Tapered drink tubes (wider as they extend down towards the bottom of the trough) allow for movement of the ice layer and prevent solid freeze-up.
Water can be supplied by two means;
a) overhead via a centrifugal pump, typically from a well with the pipe draining back to the source (or)
b) underneath via a pressurized line buried below the frost line.
