Compressor Applications

Mechanical Seals Used In Compressors

Reliability, durability and ease of maintenance are design aims that are understandably taken for granted for most applications, but they are especially applicable to the refrigeration compressor market.

Roplan develops mechanical sealing solutions for open refrigeration compressors, which are crucial to food quality. They are used within refrigeration plants employed for freezing, cooling or processing meat, vegetables, dairy products and fish – and also for conditioning fruit such as bananas.

The mechanical seal must also meet evolving environmental requirements without compromising its performance integrity. The increasingly demanding needs of wholesale and retail food sectors hinge on the performance combination of compressors and Roplan mechanical seal assemblies.

Roplan’s ability to design and engineer a seal assembly to meet the specific requirements of a compressor – and thus increase customer value – is a major factor in our being selected by a number of leading refrigeration compressor manufacturers.
