A Double Shaft Seal for the Refrigeration Compressor |
 |
 |
|
A shaft seal is the most fragile part of the industrial refrigeration system because 85% of mechanical seals fail prematurely and unexpected. Therefore, mechanical seal failure continues to be the single greatest problem in compressor operation. RM Support has developed a perfect solution: a double shaft seal with a pre-warming system.
The double shaft seal, also known as the double barrier seal, actually contains two seals, a primary and a back-up seal, found within one housing. Double shaft seals contain their own cooling system. When the primary seal fails, the back-up seal takes over, while simultaneously activating the warning system.Refrigerant (e.g. ammonia gas) will not leak into the atmosphere and production can continue.
Read about the role of a double shaft seal in the refrigeration process, and about blistering and the reasons why shaft seals fail.
