Individual solutions
Our flexible organization allows us to respond to individual requirements and non-standard needs of a specific project. An individual, tailor-made system designed for a specific application guarantees the customer the best possible solution without compromise.
Equipment can be designed to meet the needs of a given project to:
- Increased energy efficiency of the system – individual design of equipment with efficiency exceeding current EU legislation with ecodesign requirements.
- High or low ambient temperatures – equipment operating in regions where ambient temperature extremes occur.
- Strict noise regulations – several low noise design options, including night mode in reduced power mode (adjustable).
- Cost criteria – for simple applications (e.g. with very low operating time), a low-cost solution can be designed to meet only basic technology requirements.
- Spatial requirements – design solutions designed to meet the needs of confined spaces.
- Individual logic functions – all algorithms for our devices are developed in-house, which allows individual functions to be added according to the technological needs of the project.
- Individual configurations – ALPENTASel design software allows you to choose from thousands of different energy configurations and additional equipment.
- Individual color design – on customer request, the final finish can be made in any RAL color.
Freecooling
Freecooling is an energy method that uses low ambient air temperatures to cool a liquid, which can then be used for industrial refrigeration or air conditioning. This system can supplement or completely replace the work of compressor cooling and achieve significant energy savings. In industrial processes, freecooling is used to cool the process fluid, and in commercial applications it is used to cool the medium for air conditioning units in buildings. If the outside temperatures drop below the corresponding value, the chiller ensures that the fluid passes through the freecooling system, which results in the use of the lower outside air temperature to cool the fluid in the system.
The application of freecooling makes more sense as the difference between the desired outlet fluid temperature and the ambient temperature increases. ALPENTA liquid coolers maximize savings by utilizing all modes of free cooling operation – i.e., also the simultaneous operation of the freecooling system and compressor cooling
to supplement cooling capacity during the transient period.
Heat recovery
In refrigeration systems, heat recovery is used to capture the waste heat generated by the cooling system. The recovered heat can be used for a variety of purposes such as heating of the building or heating of domestic and process water. The heat recovery process can thus lead to reduced energy consumption, lower greenhouse gas production and a lower carbon footprint.
ALPENTA chillers and heat pumps can be equipped with partial or full heat recovery according to the requirements of the specific installation.
- Partial heat recovery – a desuperheater is a device that extracts heat from the superheated refrigerant gas at the discharge of the compressor so that the refrigerant does not condense. It is usually located between the compressor and the condenser in the refrigeration system. This allows the condenser to use the high temperature energy of the superheated refrigerant gas to heat the water to a higher temperature than would be possible in a condenser.
- Full heat recovery – the unit is equipped with an additional water condenser that allows all the thermal energy, including condensation heat, to be recovered. The total energy recovered is then the approximate sum of the thermal energy extracted by the evaporator and the electrical energy supplied by the compressor section.
Intelligent control system
ALPENTA is developing the ALPENTA Control System (ACS), which provides several advantages for the technological efficiency of the plant, the possibility of connectivity via different interfaces and the automatic recording of operating data independently of all data connections.
- The control system is equipped with a number of protective functions, the so-called power limitation for operation at conditions at the technological limits and is also equipped with a multifunctional protection against mains power failures.
- Thanks to the implementation of various bus interfaces, ALPENTA devices can be easily integrated into existing technology systems. These interfaces include industrial Ethernet, Modbus-RTU, Modbus-TCP/IP and BACnet, among others.
- Operational data logger - recording and analyzing a wide range of process data is increasingly important. The PLC automatically saves data as a *.csv file on an SD memory card with the option of retaining a complete history for 5 years from the time of commissioning (standard setting). Data can be easily uploaded to a PC at any time and converted to visualize operating conditions, calculate energy savings, check limit states, operator interventions, etc.
- By connecting and pairing the WIFI module with the unit, the unit can be remotely controlled using an Android/iOS smartphone app. In the app, it is possible to check the current values of all parameters or change the basic settings and operating mode.
For IOS devices
With the ALPENTA app, you can control the device yourself, without special knowledge.
For ANDROID devices

Switching to eco-friendly refrigerants
Regulation of fluorinated greenhouse gases based on the European Union regulation, which aims to gradually reduce the amount of fluorinated greenhouse gases used until 2030, sets annual quantitative limits for placing these gases on the market. The maximum amount of these gases throughout the EU has been gradually reduced since 2015. Modern refrigerants are produced with regard to reducing greenhouse gas emissions and protecting the environment. These refrigerants are designed to have a low climate impact while maximizing energy efficiency. Alpenta develops, tests and gradually markets equipment using refrigerants with low global warming potential (GWP) – R454B, R452B, R32, R513A, R290.
Devices filled with certain types of refrigerants (e.g.: R290) are equipped as standard with refrigerant leak detectors with an automatic system for disconnecting electrical devices from the voltage, possibly with a ventilation system for critical parts of the device. To process the technical design of equipment with class A2L, A3 refrigerants, it is possible to use the ALPENTASel design software or contact the ALPENTA sales office directly.
