The basic element of AOW tanks are the evaporators, which our company manufactures entirely from stainless steel. This ensures a much longer service life for the evaporators, which are submerged in water at all times. To efficiently transfer the cold from the evaporators, we use highly efficient agitators that create a constant flow of chilled water around the evaporator coils. We manufacture evaporators for various factors, such as NH3 ammonia, propylene/ethylene glycol, potassium formate (freezium).
The purpose of AOW reservoirs is to accumulate the cold generated at times of overproduction (usually at night) in order to be able to use it at peak production times when it is needed most. The cold is stored in the form of ice, which is deposited on the evaporator coils when they are operating, then cools the ice water.
Benefits of using a storage chilled water tank:
- Saving on production costs: ice is accumulated at night when electricity is cheaper.
- Less wear and tear on chillers: even load operation without sudden capacity peaks/stops.
- Reducing aggregate electricity consumption through night-time production at lower outdoor temperatures.
- Reduced cooling power requirement for the entire plant.
- Having a secure buffer that is able to meet the needs of the production facility for a short shutdown for maintenance or servicing of equipment.
- Reliability and longevity of AOW due to low complexity, and reliability due to the use of only proven technologies.
The advantage of using AOW tanks:
- Accumulation of cold
- Having a secure buffer
- Less power requirement for the entire installation
- Reduction of overall electricity consumption
