Metos Innovative Dishwashing Systems

METOS ICS+ RACK CONVEYOR MACHINES
Where do the savings come from?
NOW THREE PROBLEMS AND THREE SOLUTIONS FOR SAVINGS – WITH THE METOS ICS+
Problem 1
A standard rack conveyor dishwasher runs idle, i.e. washes empty
spaces between racks about 50 % of the operation time. Even if
one corner of the rack is in the tank the machine is running and
consequently a great amount of water, electricity and chemicals
are used.
The illustration on the right shows how fresh water
consumption increases when the washing process time
increases, i.e. the slower conveyor speed may even double
the rinsing time compared to the faster programme.
Metos ICS+ final rinse fresh water consumption is always
constant, with both the faster and slower programme.

Problem 2
Most of the rack conveyor machines have two conveyor speeds.
Programme 1= faster programme (100 racks/h) has a final rinse
time of 36 seconds per rack.
Programme 2= slower programme (50 racks/h) has a final rinse
time of 72 seconds per rack.
With the slower programme fresh water consumption is doubled,
because the rack moves through the rinse zone with a slower speed.
Consequently the costs of fresh water, electricity and chemicals
are doubled.
