Inspections and Corrective Actions
GENERAL CONDITION OF THE EQUIPMENT
The inspection should focus on following areas:
•
damage of corrosion protection
•
signs of scale formation or corrosion
•
accumulation of dirt and debris
•
presence of biofilms
Smaller damages of the corrosion protection MUST be repaired as soon as possible to prevent the damage from
getting bigger.
If there is evidence of scale formation (more than 0,1 mm) or corrosion, water treatment regime must be checked
and adjusted by the supplier.
If there is evidence of biofilms the system, including piping should be drained, flushed and cleaned of slimes and
other organic contamination. Refill system with water and apply biocide shock treatment. Check pH value and
functionality of ongoing biocide treatment.
On a monthly basis, inspect the frame and exterior panels, for signs of corrosion or any unusual conditions. If
corrosion is found, wire brush the area and treat with a cold galvanizing, zinc rich compound (ZRC).
ICE CHILLER® TANK
All ICE CHILLER
®
Thermal Storage Units are provided with sectional insulated tank covers, which, when kept in
place, will minimize the accumulation of trash or debris in the tank.
Quarterly, remove the access cover and inspect the interior of the unit for signs of scale formation, corrosion, or
biological growth on the tube bundle. If present, initiate or modify the water treatment program (see section "About
Repeated freezing and thawing can cause some minerals dissolved in the water to precipitate. If observed,
this is not a cause for concern.
ICE CHILLER® WATER LEVEL
On a monthly basis and at seasonal start-up, inspect the water level in the ICE CHILLER
®
tank. To properly check
the water level in the tank,
the ice must be completely melted
.
At seasonal start up, and at least once a month thereafter during the operating season, conduct a full melt-out and
continue to add heat to the tank until the water temperature is approximately 4,4°C. Then check the water level in
the sight tube. Add or remove water from the tank as necessary to restore the level to "0% Ice" in the sight tube.
