By implementing such solutions, we can reduce our dependence on harmful fossil fuels and focus on effective alternatives that protect our environment. Companies that implement these measures will not only reduce their operating costs, but also make a positive contribution to the environment and generate long-term benefits for their businesses.

Explanation of the individual components of efficiency

What are industrial ice banks and their energy efficiency?

Industrial ice storage is an innovative solution for energy generation and storage. The principle of phase change heat makes it possible to store large amounts of energy and make it available when needed. By freezing water during cheaper energy prices or at times when the energy supply is less stressed, the stored cold can be used during the day or when needed. This offers companies great flexibility in their energy supply and helps to reduce costs. Industrial ice storage is therefore not only a sustainable alternative, but also an economically sound investment. Especially in summer, when energy costs and demand are higher, the ice in the ice storage is used to meet the cooling needs of the industrial process.

How do industrial ice banks work?

The evaporator plates are placed upright in a rectangular or round water tank and form ice at an evaporation temperature between -4 and -10 °C. This ice remains static on the evaporator plates. This remains statically attached to the evaporator plates and is evenly distributed by water running back to the bottom of the tank via a distribution system. In addition, a special distribution system ensures intensive swirling of the air to guarantee perfect heat transfer and low ice water temperatures. This is particularly important to ensure continuity in ice production. The automatic start-up of the air circulation only when needed also ensures more efficiency and energy savings.

Unlike other energy storage systems, such as batteries, ice storage systems are very durable and have a high storage capacity. They can also be installed quickly and easily and require only low maintenance costs.

Efficient cooling is of great importance for many companies. Especially in industries such as food production or pharmaceuticals, maintaining low temperatures is essential to ensure the quality of the products and thus the trust of the customers. With the technology of an almost constant ice surface until the end of the cooling phase, maximum cooling performance is achieved at the lowest ice water temperatures. In this way, companies can ensure that their products are always delivered in the best possible quality.

How does a heat pump work?

Heat pumps are an excellent option for heat generation and use, as they can absorb heat energy from various sources and bring it to higher temperatures in no time. The principle of operation is similar to that of a refrigerator, with the difference that the heat absorbed is used to heat buildings or processes. There are numerous ways to operate heat pumps, such as by using the ambient air, the ground or groundwater. With a view to sustainable and efficient heat production, the use of heat pumps is a smart option.

What Is a Heat Pump?

A heat pump is an innovative technology that allows heat energy to be efficiently transferred from a place with a lower temperature to a place with a higher temperature. This device is particularly successful in industrial use, as it provides a sustainable and emission-free way to use the heat from the ice storage and transfer it to the cooling system of the industrial process. A heat pump can extract energy from the ambient air, groundwater or geothermal heat, making it a renewable energy source. Unlike conventional heating systems, which are based on fossil fuels and pollute the environment, the heat pump is an environmentally friendly option that offers economic and operational advantages at the same time.

Combination of industrial ice banks and heat pumps as sustainable energy efficiency

How can industrial ice banks be combined with heat pumps?

Combining industrial ice storage with heat pumps offers an efficient way to generate energy in the form of heat. With the help of heat pumps, the stored cold energy can be converted into usable heat energy during the warm season. In doing so, the system is not only energy-efficient and environmentally friendly, but also offers an economical alternative to traditional heating systems. Especially for companies that focus on sustainability, this technology is an interesting solution to save costs and at the same time contribute to climate protection.

How can the combination of industrial ice storage and heat pumps contribute to energy savings?

Combining industrial ice banks and heat pumps is a promising way to reduce energy consumption in industry. This method uses surplus energy to fill the ice storage, which is then used to generate thermal energy when it is needed. Thanks to this innovative technology, industrial companies can effectively counteract their energy consumption while also reducing their CO2 emissions. Companies that want to underline their commitment to sustainability and environmental sustainability should therefore consider this advanced technology.

Using industrial ice storage in combination with heat pumps is an extremely effective way to save energy and significantly reduce a company's energy needs. By using surplus energy in the form of cold to generate heat, considerable progress can be made in energy efficiency. In fact, by combining ice storage and heat pumps, businesses can save up to 50 per cent energy compared to traditional heating and cooling methods. Investing in a company's energy efficiency in this way can help reduce costs, protect the environment and improve the company's image.

Industrial production is an important part of our modern world, but it requires an enormous amount of energy. Traditionally, this energy is derived from fossil fuels, which is unfortunately both expensive and harmful to the environment. For this reason, companies are looking for new and advanced ways to lower their energy costs while reducing their carbon footprint. One promising technology for this is the combination of industrial ice storage with heat pumps. This can not only save energy, but also produce more sustainably - an important step towards a cleaner and more efficient future.

Will a heat pump lower my energy bills?

Ice banks in combination with heat pumps offers numerous advantages for the industry:

  • Energy savings: Ice storage allows for cost-effective storage of energy while energy prices are lower. This stored energy can then be used to meet the cooling needs of the industrial process. This reduces the energy demand of the industrial process and lowers energy costs.A big advantage of this technology is that it is very efficient. Heat pumps can generate up to four times more thermal energy than they consume electrical energy. Since ice storage can store thermal energy at a very low temperature (down to -8°C), it is possible to generate thermal energy with a high level of efficiency. Thus, by combining industrial ice banks and heat pumps, a significant amount of the total energy required can be saved,
  • Environmentally friendly Ice storage in combination with heat pumps reduces CO2 emissions and is therefore more environmentally friendly than conventional systems. By using renewable energies such as ambient air or geothermal heat, the environment is protected. The combination of ice storage and heat pumps is environmentally friendly. Since less energy is needed to cool the production facilities, less CO2 is emitted.
  • Efficiency: The combination of ice banks and heat pumps enables a higher efficiency of the industrial process. The cooling systems can be operated at a higher efficiency and thus the energy demand is reduced.
  • Long-term cost savings: Although the investment costs for installing an ice bank system and a heat pump can be higher than for conventional heating systems, these systems lead to significant cost savings in the long run. The advantage of this combination lies in the energy savings. Since the ice is produced at night when electricity is cheaper and used when it is needed, the company can optimise its electricity consumption and save costs. As the heat pump is also a renewable energy source, the company can reduce its CO2 emissions and produce in a more environmentally friendly way.


Industrial ice banks combined with heat pumps has become a promising technology in the energy saving market. By using cheap electricity and renewable energy sources, the company can reduce its energy costs and at the same time reduce its CO2 emissions. Companies that try this technology will not only save money, but also make an important contribution to environmental protection.
