Ice bank is basically the immersion chiller, namely a assembly of many pillow plates banked together and immersed in a
container filled with liquid.
The Ice Bank system is a technology by storing cooling capacity at night and using it the next day to cool. At night the electricity cost is relatively lower, chillers cool water and store it normally as icy water or ice.
Moreover, lower temperatures at night allow refrigeration equipment to operate
more efficiently, reducing energy consumption. Less chiller capacity is required, which means lower initial
capital equipment cost.
Using off-peak electricity to store cooling capacity reduces peak daytime power consumption,reducing additional expensive power charges.
How does an Ice Bank work?
An ice bank is a assembly of Pillow Plates that is hung in a container with water.
At night when the energy cost is low, the plates freeze the water in the tank.In the daytime when the power is more expensive, the cooler is turned off. The stored ice melts into ice water, which can be used to indirectly cool down your products.

Laser welding pillow plate:
Heat exchange pillow plate is machined by full automatic laser
welding and forming process. Its unique pillow structure makes
fluid into optimum turbulence state to achieve high efficient heat
exchange. It also boasts various advantages such as dust proof,
high temperature and high pressure resistance and easy cleaning,
Pillow plate concept:
Pillow plate is laser welded by two plates all around and in the
middle area full of weld flowers. After the forming process, the
inner part of the heat exchange plate forms a pillow type cavity.
Pillow design creates excellent turbulence and provides self
supporting structure. In practical applications, the additional
welding path is often added in the pillow heat exchange plate, in
order to adjust and control the flow of fluid into and out of the
heat exchange plate nozzle position, the fluid velocity and flow
rate inside plate, so as to optimize the heat exchange effect.
Pillow plate Advantages:
- Excellent turbulence design, high heat exchange coefficient
- High welding realiability
- Small external surface resistance, not easy to product dirt
- High temperature and high pressure resistance
- Wide channel, low pressure drop, easy to clean
- Flexible shape to maintain optimal heat exchange effect
