Technical Design

Refrigeration systems engineered by EPTA

Choosing our Group means choosing refrigeration systems designed and built to client specifications. In fact, Epta uses specialized teams to meet the needs of clients by designing the perfect solution for every refrigeration system.

The first step is an analysis of the specific needs and environmental conditions, followed by the design, development and installation of refrigeration systems that fully respond to the desire to curb energy consumption and ensure the best performance levels.

Epta is known for its ability to produce and install CO2 refrigeration systems all over the world, its experience increasing over the years with the many trans-critical, subcritical systems built and installed: a truly significant expertise, considering the current need to comply with increasingly stringent restrictions on the use of synthetic refrigerants as opposed to natural systems like carbon dioxide.

FTE (Full Transcritical Efficiency) system

Within this environmentally friendly landscape, Epta developed a revolutionary transcritical system: CO2 FTE (Full Transcritical Efficiency) System that matches simplicity and performance, with installation and maintenance costs that are up to 20% lower compared with traditional CO2 systems. Simple, Global, Industrialized and Reliable: These are the features of the new system that guarantee utmost efficiency for Retailers worldwide thanks to its outstanding performances in any climate. In the 2.0 version, the FTE Full Transcritical Efficiency can be fully integrated in the power pack thus requiring no extra space in the technical room and further reducing installation and startup times.

ETE (Extreme Temperature Efficiency) system

ETE Extreme Temperature Efficiency is a new technology by Epta that can be combined also with FTE to guarantee operation of the transcritical CO2 system at any latitude and at any temperature, even higher than 40°C, also on non-booster installations, and in industrial refrigeration applications. The technology works without the support of synthetic, flammable refrigerants, or the use of water: the system uses the same CO2 of the transcritical system as its work fluid. The “secret" of the ETE lies in the reduction of refrigerant temperatures before it is distributed to the final utilities.  The gas, going out from the air exchanger, at a value close to ambient temperature, is cooled further. The system allows the almost total disappearance of “flash-gas" (refrigerant to recompress), for significant energy saving and guarantees of the reliability of the correct operation of the system, also above 40°C. Another strong point of FTE and ETE is the choice of standard components, easily available and known to the operators, to ensure not only easy installation, but also greater efficiency in the start-up and maintenance phases.
