Innovative benefits with the KONZMANN Group in the field of cooling technology

Optimised energy use

By using modern technologies and natural refrigerants, energy use can be optimised according to requirements and operating costs can be reduced.

Reliability

Our customized refrigeration solutions ensure maximum operational safety and long service life of your systems.

Resource and energy use

By using natural refrigerants and demand-based system design, energy use can be optimised and the use of certain fluorinated refrigerants can be reduced.

Comprehensive service

From planning and installation to maintenance, we offer you everything from a single source.

Use the online F‑Gas Check! Clarity in 5 minutes

With the current F-gas Regulation (EU) 2024/573, the EU is tightening the requirements for the use of fluorinated refrigerants in refrigeration, air-conditioning and heat pump systems. The aim is the gradual phase-out of HFCs by 2050. Quantity restrictions and application-specific bans on refrigerants with a high GWP (Global Warming Potential) already apply. For operators and planners, this means: Early consideration of low-GWP refrigerants and natural refrigerants such as CO2 (R744), ammonia (NH3) or propane (R290) can help align systems with future regulatory requirements.

Energetic Optimization
of Your Refrige­ration Systems

Whether ice rink, machine tool cooling, or NH3 application in a dairy, brewery, or food production – all industrial refrigeration systems are individually designed.

Leistung_Kaelte_Klimaschutz_u_Co2_Neutralitaet

Reduce emissions and optimise energy use

Particularly in light of the new F-gas Regulation, considerable attention is paid to demand-based energy use and the selection of suitable refrigerants during both planning and implementation. Regardless of company size, the energy performance of a refrigeration system should be considered from the planning stage onwards. Life-cycle criteria can play an important role, as can the use of waste heat through heat recovery. Economic payback periods and operational reliability are also key considerations.

Food refrige­ration
without interruption

Refrigerated cabinets, cold rooms, or liquefaction and combined systems: KONZMANN supports your business in setting up cooling rooms and storage facilities of any size – from standard refrigeration to ultra-low temperature cooling.

Complete provider for cold chain systems

Around 50 per cent of total energy consumption in food retail can be attributable to refrigeration. In addition, the F-gas Regulation introduces phased restrictions on certain fluorinated refrigerants. It can therefore be worthwhile to modernise existing systems or replace them with technically optimised solutions. As a full-service provider, we support you and your cold-chain system from project planning and implementation through to regular operation and beyond.

Compact ice storage systems

Ice storage systems are used in industries with short-term high cooling demands and phases of low cooling load. These systems are commonly employed in the chemical industry, breweries, dairies, and the food industry.

Storing cooling energy in the form of ice is a proven technology for many sectors, as it allows the required cooling capacity to be supplied in sync with the cooling demand—without the need for a large cooling unit with high electrical power consumption.

  • Wide performance range: 12 capacity levels from 20 kW to 260 kW storage capacity
  • Compact ice storage system
  • Required cooling capacity synchronized with cooling demand
  • Proven technology

Liquid coolers (Chillers / chilled water units)

Refrigeration systems for cooling liquids in industrial applications are designed for demand-based energy use and high operational reliability. Depending on the application temperature, free cooling systems can help improve the seasonal performance factor.

The integration of renewable energy sources is also possible. To optimise energy use, individually adapted cooling systems with heat recovery via desuperheaters, heat recovery condensers or economisers are available.

  • high economic efficiency with high availability
  • optional: design based on life-cycle criteria
  • process-oriented design possible (refrigeration circuit, hydraulics, control and regulation)

Rethinking energy: Heating and cooling with large-scale heat pumps for commercial and industrial applications

Rethinking heating and cooling with innovative technology – unlock potential within your business.

Large-scale heat pumps provide a technical solution for supplying heating and cooling in industrial and commercial applications. They make it possible to use previously unused waste heat from production processes or building services as an energy source and reduce the use of fossil fuels. Modern large-scale heat pumps can operate at high capacities and can also be used for industrial processes with higher temperature requirements, for example for heating, air-conditioning or hot water production in large buildings and production facilities.

Integrating large-scale heat pumps into existing systems, often combined with heat recovery and intelligent controls, can reduce operating costs and the use of fossil fuels. Energy use can be further optimised where systems are operated using electricity from renewable energy sources or in combination with photovoltaic systems. Flexible cascade configurations of several heat pumps make it possible to meet heating and cooling demand according to requirements, even under fluctuating loads.

Large-scale heat pumps are used in applications including the textile and food industries, paint shops, data centres and the heating and cooling of office and commercial buildings. By using available waste heat and potentially replacing fossil fuels, they can contribute to reducing operational CO2 emissions.

The companies of the KONZMANN Group provide complete planning, design and implementation of large-scale heat pump solutions, tailored to the individual requirements of each industrial or commercial operation. By analysing existing processes and energy sources and integrating modern control and heat recovery systems, each system is designed according to the specific requirements. In this way, the experts of the KONZMANN Group support customers in optimising energy use and making use of available potential to reduce fossil fuel consumption and operational emissions.
