METOS ICS+ RACK CONVEYOR MACHINES
Where do the savings come from?
Two problems and two solutions for savings – with the Metos ICS+
Problem 1
Switch
A standard 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
Standard dishwasher
slower programme
50 racks/h
Rinse time 72 sec. / rack
Most of the 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.
