Ceramic control discs for maximum efficiency in refrigeration technology
Expansion valves are the heart of modern refrigeration systems and heat pumps.They control the refrigerant flow to the evaporator and thus have a direct influence on the efficiency and operational reliability of the entire system. Ceramic control discs from CERA SYSTEM set new standards in this area:
They minimize internal leaks, offer excellent sliding properties, and ensure precise control—even at high pressures, changing temperatures, and aggressive media. The result: stable processes, less energy loss, and a significantly longer service life for the system..
Typical applications
Where ceramic control discs are convincing
- Expansion valves in refrigeration systems – precise control of the refrigerant flow
- Heat pumps – reliable sealing at high pressure differences
- Industrial refrigeration and air conditioning systems – durable components for continuous operation
