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
water care" on page 21).
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.
During normal operation a solid layer of ice at the top of the tank will not form. However, should such a
layer be formed due to unforeseen and unwanted operational circumstances, the low level alarm can be
activated. In such case melt out the ice completely.
COIL
The coil should be observed when there is no ice on the coil.
1. Inspect the coil for
- obstructions
- damages
- corrosion
- fouling
2. Remove any obstructions from the coil
Any damages or corroded areas need to be repaired. Call your local BAC representative for assistance.
Regular checking of the total aerobic bacteria count (TAB) and maintaining it within acceptable levels are the key
to prevent fouling.
The coil support is a part of the structure of the tank. In case the coils need to be removed, the tank must be
emptied.
CAUTION
Do not remove or loosen bolts from the coil supports when the tank is filled with water.
ICE LOGIC™ ICE QUANTITY CONTROLLER
Check monthly the control sensors for any visual signs of damage.
GLYCOL
Every six months, or at the seasonal start-up, draw a sample of the glycol solution from the system and check the
concentration using a refractometer. If necessary, adjust the concentration using the proper type of industrially
inhibited glycol.
