Are you concerned about the fire hazards during centrifuge operation in your bulk pharmaceutical unit? Centrifuge blanketing systems play a crucial role in ensuring the safe and efficient operation of centrifuges, particularly in industries such as pharmaceuticals where high-speed processing of solvents is common.

What is a Centrifuge Blanketing System?

Centrifuge blanketing systems provide continuous inertization, encompassing blanketing and purging processes, to mitigate the risk of fire and explosion associated with centrifuge operation. These systems use nitrogen gas to displace oxygen inside the centrifuge enclosure, keeping the atmosphere below the explosive limit at all times.

Application and Importance

In pharmaceutical applications, centrifuges are utilised for separation processes involving various solvents at high rotating speeds. The high-speed rotation can generate sparks in the bearing housing, posing a significant fire hazard. Nitrogen purging is conducted before startup, while continuous nitrogen blanketing is recommended during operation.

Centrifuging operations often involve handling flammable liquids, further heightening the risk of fire and explosion. To mitigate these risks, inert gas purging — typically using nitrogen — is employed before operation, and inert gas blanketing is maintained throughout, effectively reducing the oxygen concentration to safe levels.

Key Functions

• Purging of the basket and bearing at startup
• Continuous blanketing of the basket and bearing during operation
• Pressure relief for the basket and bearing
• System inertization and reduction of oxygen levels to below explosive limits

Configuration and Features

Centrifuge blanketing systems are available in fully automated or manual configurations. They include nitrogen supply, pressure regulation, flow measurement, and safety interlocks to ensure safe operation at all times. Nirmal's CBS Series systems are factory assembled, tested, and supplied complete for easy installation.
