The E355 series uses an innovative
and patented design that opens a port at the top of the outlet as the valve shuts off the
flow of water into the cup. By allowing air into the dispense pipe like this the flow of
water into the cup is improved, filling a standard sized cup in under 2.5 seconds.
The vent after vend design also gives a move precise shut off with a "cleaner"
end to the flow.
The E355 will operate successfully
with a very small head of water allowing it to draw water the hottest water from the top
of the boiler.
