Ice Formation Pattern

Evaporator ice formation pattern analysis is helpful in

ice machine diagnostics.

Analyzing the ice formation pattern alone cannot

diagnose an ice machine malfunction. However, when

this analysis is used along with Manitowoc’s Freeze

Cycle Refrigeration System Operational Analysis

Tables, it can help diagnose an ice machine

malfunction.

Any number of problems can cause improper ice

formation.

1. Normal Ice Formation

Ice forms across the entire evaporator surface.

At the beginning of the Freeze cycle, it may appear

that more ice is forming on the inlet of the evaporator

than on the outlet. At the end of the Freeze cycle, ice

formation at the outlet will be close to, or just a bit

thinner than, ice formation at the inlet. The dimples in

the cubes at the outlet of the evaporator may be more

pronounced than those on the inlet. This is normal.

It is normal for ice thickness to vary up to 1/16" across

the surface of the evaporator. The ice bridge thickness

at the ice thickness control probe should be at least

1/8".

The ice thickness probe must be set to maintain the

ice bridge thickness at approximately 1/8 in. If ice

forms uniformly across the evaporator surface, but

does not reach 1/8 in. in the proper amount of time,

this is still considered a normal ice fill pattern.

Important

Keep the water cu rtain/ice da mpers in pla ce whi le

checking th e ice formation p attern to ensure no

water is lost.
