Grasso RC411 Compressor

• Industrial refrigeration for large-scale cold storage facilities.
• Freezing applications in food processing plants, such as meat, fish, or dairy.
• Climate control for pharmaceutical production and storage.
• Chemical and petrochemical process cooling.
• Ice production plants, as indicated by its previous use with an ice machine.

Typical refrigeration capacity

For this class of industrial compressor, capacities commonly range from 100 kW to over 500 kW, depending on refrigerant and operating conditions. Buyers should contact the seller for exact unit performance.

Power supply

Industrial compressors of this size typically require a three-phase electrical supply, commonly 400V/50Hz in the UK, with significant current draw. Specific electrical requirements should be confirmed with the seller.

Refrigerant type

While this unit was previously used with Freon, modern installations often utilise HFCs or natural refrigerants. The specific refrigerant compatibility of this unit should be verified with the seller.

Compressor type

Grasso RC series compressors are typically screw compressors, known for their efficiency and reliability in industrial applications.

Footprint

As a skid-mounted unit, it will have a self-contained footprint, typically several square metres, which facilitates installation. Exact dimensions should be obtained from the seller.

Maintenance requirements

Industrial compressors require regular scheduled maintenance, including oil changes, filter replacements, and system checks, to ensure optimal performance and longevity.

Control system

This unit is described as 'without control panel', meaning an external control system would be required for operation. Buyers should factor this into their installation plans.

• What is a Grasso RC411 compressor typically used for?

  The Grasso RC411 is an industrial-grade compressor commonly used in large-scale refrigeration and freezing applications, such as cold storage, food processing, and ice production plants.

• What does 'skid-mounted' mean for this unit?

• Can this compressor be used with refrigerants other than Freon?

• What does 'without control panel' imply for installation?

• What is the typical lifespan of a used industrial compressor like this?

• What should I consider when buying a used compressor of this type?

Used air compressors for lab and pharma applications are generally valued for reliability and cost savings. Buyers typically prioritize checking maintenance history, confirming pressure ratings meet specific requirements, and verifying oil-free operation where contamination control matters. Key strengths include durability when properly serviced, consistent performance across extended operational hours, and significant capital cost reduction compared to new units. Inspecting seals, checking for corrosion, and confirming recent servicing records are standard considerations when purchasing secondhand.
