The food products frozen using the ηmax Refrigeration System are greatly appreciated around the world for their high quality, and many have been exported to EU countries. However, the freezers are often required to meet the standards set by the importing country. Another potential issue associated with exporting is how to ensure reliable operation by local staff after installation.
The following outlines how the ηmax Refrigeration System obtained the CE marking certification and gives some examples of overseas operations.

With the certification, a mark (commonly called “CE mark”) to indicate conformity with applicable regulations can be placed on products sold in the EU. The mark ensures the buyer that the product has met the requirements of applicable EC directives and standards. A product bearing the CE mark is guaranteed free access for sales and distribution within the EU.
Nakayama Engineering went through the following five steps and, in 2014, obtained CE marking certification for its ηmax Refrigeration System.
1. Identification of applicable directives and standards
2. Identification of requirements
3. Compliance evaluation
4. Preparation of technical documentation
5. Preparation of conformity declaration and affixing CE mark
With CE marking certification, exporting the ηmax Refrigeration System to the EU is now much less challenging. We welcome all inquiries from customers who are considering the installation of the system in the EU.
Below are some of the highlights for the use of the ηmax Refrigeration System outside Japan. The version for the EU, Oceania, and North America has the following features:
The ηmax Refrigeration System for export has a simple design to ensure reliable operation in the local environment. It is unique in that it creates ultra-low temperatures (–70°C) with HFC refrigerants and a two-stage compressor.
Ultra-low-temperature refrigeration systems typically employ dual refrigeration using refrigerants with low boiling points. However, as refrigerants with low boiling points create high pressure at ambient temperature, proper pressure management is rather complicated and accidental leakage can occur, making stable operation difficult. The ηmax Refrigeration System has a simple configuration that allows operational reliability and cost saving.
The ηmax Refrigeration System achieves reliable freezing by drastically reducing frost build-up. The key to this is a small temperature difference (TD) between refrigerant and ambient air. When the ambient temperature is around –60°C, TD (the difference between the temperature in the freezer room and the refrigerant evaporation temperature) is 4°C, and when the ambient temperature is about –70°C, TD is 2°C. This TD is far smaller than that of any other commercially available refrigeration system. With this minimal TD, frost build-up severe enough to cause operational problems is prevented throughout the freezing process, thus achieving reliable, high-quality freezing.
The current operating status of the ηmax Refrigeration System can be remotely monitored for review. Periodic maintenance is conducted by engineers from the local installation contractor. The combination of these services enables your local staff to run the system smoothly.
