Refrigeration Equipment
Partner no.1
Modern supermarkets, grocery stores, butcher shops, bakeries, discount stores and other retail premises require a reliable refrigeration solution that can operate every day with a large number of refrigerated display counters, cold rooms and different temperature zones. This is why CO₂ refrigeration systems are becoming increasingly important in professional refrigeration for commercial premises.
When a refrigeration system is designed from the outset around the actual requirements of the premises, it is not enough to simply select a refrigeration unit or central system. It is essential to coordinate the refrigerated display counters, cold rooms, evaporators, pipework, controls, automation and overall energy efficiency of the system.
Frigo Zika approaches each project as a complete solution, from concept development and design, through the selection and production of refrigeration equipment, to fitting out the retail premises with a functional and professional refrigeration system.
CO₂ technology is particularly suitable for premises with a large number of refrigeration units and the need for different temperature zones. These include:
For larger premises, the advantage of a centralised system is that multiple refrigeration units can be connected to a shared refrigeration pack.
This allows the entire installation to be designed as one functional system, rather than as a collection of separate, independent units.
Refrigeration in a supermarket needs to be much more than a system that simply “maintains the temperature”. It must ensure stable operation throughout the day, appropriate conditions for different product categories, efficient energy consumption and straightforward management of the entire system.
CO₂ is a natural refrigerant and is designated as R744. Its GWP is 1, making it significantly different from refrigerants with a high global warming potential. The European Commission lists a GWP of 1 and an A1 safety classification for R744.
When a supermarket has a large number of refrigerated display counters, cold rooms and freezers, a centralised CO₂ solution can be highly practical. A well-designed refrigeration pack can serve a large number of refrigeration units.
Not everything in a supermarket needs to be kept at the same temperature. Dairy products, meat, fruit and vegetables, frozen food and products stored in cold rooms all have different requirements. For this reason, the system is designed according to the specific premises and the customer’s requirements.
Regulations and the market are increasingly moving towards refrigeration technologies with a lower environmental impact. The new EU F-gas Regulation 2024/573 further tightens rules on fluorinated gases and promotes the transition towards more climate-friendly solutions.
For this reason, an investor planning a new supermarket or the renovation of an existing premises should consider not only the current investment, but also how the refrigeration system will perform and operate in the years ahead.
Transcritical CO₂ systems are commonly used in larger commercial premises. Their specific characteristics are related to the way CO₂ systems operate and the fact that their operating parameters differ from those of conventional refrigeration systems.
This means that designing a CO₂ refrigeration pack requires experience, the right choice of components and precise sizing. Simply increasing or reducing compressor capacity is not enough.
The entire refrigeration load of the premises, temperature zones, number of refrigerated display counters, pipework lengths, operating conditions and control strategy all need to be taken into account.
In a well-engineered system, attention is also paid to ensuring stable operation under varying loads. A supermarket does not have the same refrigeration demand in the morning, during peak shopping hours, at night or during holidays.
The system must be able to adapt to the actual operation of the premises and changes in refrigeration load.
A complete refrigeration solution for a supermarket consists of several interconnected components. Each of them affects the reliability, energy efficiency and overall performance of the system.
CO₂ refrigeration pack is the heart of the system. It connects different refrigeration loads and enables centralised control of refrigeration capacity.
Refrigerated display counters are the part of the system that customers see directly. They must provide the appropriate product temperature, good product visibility, easy restocking and an attractive appearance in the retail space.
Frigo Zika offers various types of commercial refrigerated display counters, including horizontal and vertical models, as well as other professional refrigeration solutions.
A retail premises cannot operate efficiently without adequate storage facilities. Cold rooms and freezer rooms enable larger quantities of products to be stored before they are displayed in the retail area.
The correct selection of evaporators and other system components directly affects heat transfer and the stability of the refrigeration system. For this reason, their selection is based on the specific operating conditions rather than nominal capacity alone.
A modern refrigeration installation requires an appropriate control and automation system. Monitoring pressures, temperatures, compressor operation and other components allows the system to adapt to changes in refrigeration load.
The most costly mistake when fitting out a supermarket is not necessarily choosing more expensive equipment. A much greater problem can arise when equipment is selected without proper calculations and without considering the premises as a complete system.
Refrigeration system design begins before any equipment is purchased. We analyse the sales area, display layout, product types, storage capacity, temperature zones, opening hours, site conditions and planned intensity of use.
Following the analysis, the refrigeration system concept is defined and the appropriate components are selected. Only then does it make sense to proceed with the detailed equipment selection.
The investor receives more than just “refrigeration equipment” – they receive a fully engineered refrigeration solution tailored to the specific premises.
When opening a new supermarket, butcher shop, bakery or other food retail premises, the entire facility needs to be planned so that the equipment is functional, easy to navigate, accessible to staff and convenient for customers.
Frigo Zika approaches the fit-out of each premises as a complete project. A wide range of professional equipment categories can be planned in one place – from refrigerated display counters and cold rooms to cooking and neutral equipment.
A key advantage is the ability to consider the refrigeration area together with the functional layout of the premises.
Every commercial premises has a different workflow, different needs and specific requirements. That is why equipment is not selected in isolation, but as part of a functional whole.
Professional supermarket fit-out requires much more than a few refrigerated display counters. Depending on the concept of the premises, refrigeration, retail, storage and cooking equipment need to be integrated into one functional system.
Butcher shops and meat retailers have specific requirements. In addition to refrigerated display counters, they often require cold rooms, refrigerated work tables, meat preparation equipment and various elements of professional butcher shop equipment.
In these premises, it is important to organise the product flow correctly, from receiving and storage, through preparation, to display and sales. The refrigeration system must support this workflow.
Bakeries require a completely different combination of equipment. In addition to cooking equipment for preparation and baking, suitable bakery display counters, bread shelving, heated display counters and refrigeration equipment are required where products need controlled conditions.
A well-designed bakery must connect the production and retail areas. The equipment must not interfere with staff workflow, while customers should have an easy view of the products and a comfortable flow through the retail space.
Frigo Zika can participate in the planning and fit-out of various types of commercial premises, from smaller specialised stores to larger retail systems.
Every serious project begins with a discussion with the investor. It is essential to understand what the premises will sell, how much space is available, what capacity is planned and what the business requirements are.
The advantage of this approach is that the investor does not have to coordinate a large number of different suppliers and contractors. When the project is managed as a whole, it is easier to control the functionality, layout and compatibility of the equipment.
In commercial refrigeration, electricity consumption represents an important operating cost. That is why energy efficiency is not achieved simply by choosing a compressor. It depends on the entire system – from the display cabinet and evaporator to the control system and the way the refrigeration plant operates.
A well-designed system should operate only as much as necessary to maintain the required conditions, without unnecessary equipment operation. Changes in load throughout the day, seasonal temperatures and the number of active refrigeration consumers must all be taken into account.
Properly selected display cabinets contribute to temperature stability and the overall energy efficiency of the system.
Efficient heat transfer enables stable operation with an optimized refrigeration system load.
The system should adjust its operation according to the actual needs of the facility and changes in refrigeration load.
A properly sized refrigeration plant enables efficient operation of a larger number of refrigeration consumers.
That is why, when choosing a refrigeration system for a supermarket, it is important to consider long-term costs, rather than just the initial investment price.
A cheaper solution that consumes more energy or requires more frequent maintenance can ultimately be more expensive than a properly designed and engineered system.
With a professional refrigeration system, the most important thing is that the equipment is adapted to the facility. That is why Frigo Žika does not view refrigeration equipment as an isolated product, but as part of the complete commercial space.
Our product range includes commercial refrigeration, thermal and neutral equipment, while our experience in equipping different types of facilities allows us to approach each solution from the perspective of the investor, employees and end customers.
There is no single refrigeration solution that is suitable for every facility. A small store with several refrigeration units does not have the same needs as a supermarket with dozens of display cabinets and a large cold room.
That is why the best first step is an analysis of the specific project. Based on the size of the facility, type of products, required temperatures, number of refrigeration consumers and operating conditions, it can be determined whether a central CO₂ refrigeration system is the optimal solution.
If you are planning a new supermarket, grocery store, butcher shop, bakery, discount store or other retail facility , planning the refrigeration system at an early stage can make a significant difference to the facility's long-term operation.
Frigo Zika can be your partner from the initial concept to a fully equipped facility – through design, equipment selection and manufacturing, as well as the implementation of the complete solution.
From choosing a CO₂ refrigeration system and engineering the solution to equipping supermarkets and other commercial facilities – answers to the most important questions before starting a project.
