Fermentec’s medium-scale and small-scale pilot fermenters are good for producing high-value precision fermentation goods or research.
Pilot fermenters that are designed and produced to ASME-BPE standards to satisfy international standards cause no corrosion or abrasion, minimize material quality degeneration through delicate processing processes, and are produced after being approved as pressure vessels that are safe in high-temperature and high-pressure situations.
The compact pilot fermenters can be installed in narrow spaces or research rooms, and can be easily operated and maintained and repaired due to their automated systems and proper arrangement of devices. They have adopted the highest-standard controllers to secure precise control and reliability of operation data, and their control program of the highest technology in the industry guarantees improved results.
Fermentec’s spirit of putting customers’ safety first is reflected in the control system and the multiple safety systems adopted for their vessel part.
