Commercial refrigeration systems

The scope of commercial refrigeration includes small to medium-capacity refrigeration systems that supply cooling for the storage of goods at low to very low temperatures. The range of applications is extensive and our clients include food service companies, supermarkets, meat markets, bakeries and many other enterprise types.

Achieving the highest level of energy efficiency has come to play an ever more important role for our clients. The selection of an appropriate refrigerant to match the system concept can have a major impact on the cost effectiveness of the implemented refrigeration system. The effective utilisation of waste heat now plays a central role in the planning of all refrigeration systems.

Industrial refrigeration systems

As an experienced engineering firm working in the area of refrigeration systems, we offer tailor-made and energy efficient solutions for your refrigeration needs. We provide our services to enterprises in a full range of industries, including logistics, food production and chemical manufacturing.

Reaching the highest degree of energy efficiency depends on a careful evaluation of the relevant facility concept and the proposed means of refrigeration. We focus on natural refrigerants such as ammonia (NH3), propane or carbon dioxide (CO2). This enables us to realise cost-effective systems for our customers, systems that also achieve the highest degree of energy efficiency while also accounting for future ecological standards.

As an engineering firm, we are independent of suppliers and manufacturers. This allows us to offer cost-effective products that are ideally suited to the needs of our customers.

Given our extensive experience, we know the various strategies and their corresponding advantages and disadvantages. Moreover, we align our services optimally to your existing HVAC and plumbing systems, making sure while doing so to minimise the number of interfaces and therefore lower the associated risks. We offer comprehensive planning services.

Industrial heat pumps

Environmentally sustainable heating has come to play an ever more important role. This applies universally, whether the aim is to heat buildings, supply hot water, realise district heating solutions, enable high temperature applications or supplement existing heating systems. Industrial heat pumps combined with anergy grids often make for ideal solutions. As an experienced engineering firm in the area of refrigeration systems, we are the right partner for all kinds of industrial heat pumps that make use of natural refrigerants such as ammonia (NH3), propan or carbon dioxide (CO2).

Our experience in the design of refrigeration systems allows us to integrate heat pumps into larger systems in an energy-efficient manner.

Air conditioning systems

As an engineering firm with its own refrigeration division, we are able to develop system concepts that can be optimally integrated into larger existing systems, whether for office buildings, hospitals or other facilities that demand higher levels of ambient comfort.

Energy efficiency and cost effectiveness are at the centre of all of our air-conditioning concepts. Indeed, all of our system concepts are also based on a profitability calculation. The use of natural refrigerants is also one of our top priorities.

Given our extensive experience, we know the various strategies and their corresponding advantages and disadvantages. Moreover, we align our services optimally to your existing HVAC and plumbing systems, making sure while doing so to minimise the number of interfaces and therefore lower the associated risks. We offer comprehensive planning services.

Ice rinks

Our experience in the planning of ice rinks encompasses direct-evaporation systems and pump circulation, indirect systems and pump circulation with CO2 technology and systems with glycol circuits.

Systems that use ammonia (NH3) as a refrigerant for the creation of ice offer optimal efficiency. The use of waste heat at various temperature levels (e.g. high temperature release via heat pumps) makes an additional contribution to excellent energy performance.

Our comprehensive planning services for ice rinks and building systems engineering helps us to reduce the number of interfaces and their associated risks.
