A significant milestone

Completion of the development of the OXY platform represented a significant milestone for the company.

Based on the platform, a family of of zirconium dioxide-based gas analysers, paramagnetic technology and fuel cells.

At the end of the same year, the OXY-ZM analyzer is acquired by is certified by LLOYD Marine for marine use.

Breakthroughs in aquaculture and the military

Another crucial moment in the direction for the company was the launch of the XB4-S probe. It is used to accurately measure the level of dissolved oxygen in aqueous media based on the optical principle.

The probe was quickly adopted by the world's leading aquaculture companies and the GRYF brand has become the brand name of choice for GRYF thanks to references such as MOWI, SalMar and Atlantic Sapphire has made an indelible mark on the environment of corporate aquaculture.

In cooperation with the University of Defence of the Czech Army Republic completed the development of the Sorptest system, a device for testing the permeation of combat gases through protective equipment using QCM (Quartz Crystal Microbalance) technology. In connection with this, GRYF has been awarded NATO approved supplier status.

Integrated Fish Farming Management

After intensive research and development in pandemic years, the platform was launched in 2022 Integrated Fish Farming Management (iffman.com).

The system is designed with the situation in which a number of previously established development companies aquaculture companies have lost their former size and a number of smaller successor companies are entering the market with a need for a strong, dedicated technology partner. The platform immediately gained the attention of of the resurgent Chilean market.
