Ice bank silo

A BUCO Ice Bank Silo with its extremely large ice surface enables the fastest possible product cooling even with a small refrigeration system, despite extreme load peaks. The efficiency of dynamic ice production with hot gas defrosting of a Buco Ice Bank Silo is based on the avoidance of thick ice sheets on the evaporator . In comparison, the heat conduction in static storage evaporators is hindered by the ice layer. Ice grants the maximum power reserve and safety.

For the best possible quality of food and dairy products, the cooling performance at peak loads must not break. The BUCO icemaker in the silo not only makes ice, but can also cool water directly to 0.5 ° C with even higher COP. Anevaporator of the ice storage system can be available at any time with free space without ice shells and therefore also be used as a direct cooler for heated return water. Direct cooling at the free evaporator allows a much higher efficiency of the refrigeration system due to a higher evaporation temperature and thus saves expensive electric drive energy.

This mode of operation should be used as often as possible for the base load, which can be controlled automatically by a PLC, depending on the return temperature of the water, automatically.

The ice freezes on the vertical evaporator plates to a thin layer of a few mm, which always keeps the thermal resistance low. After a few minutes of ice formation, hot gas is fed into the evaporator plates for a few seconds via an automatic controller, SPS, to separate the ice surface. Thereafter, the evaporator is again in effective form ready for a new icr msking cyclus.

We have always assimilated engineering science and thermodynamics optimally in the various manufacturing processes.

Thermodynamicists,mechanical engineers and welding engineers define the dimensioning, design and construction of customised heat exchanger panels and systems in materials ranging from mild and austenitic steels through to titanium, and ensure successful distribution of their work worldwide.

In doing so they fall back on production engineering expertise and calculations developed in the course of the past hundred years that are still being continuously optimised in an ongoing process.

In the perception of our customers, the Buco product stands for:

  • Technical and process-oriented consulting
  • Thermodynamic efficiency
  • Quality and longevity
