GEA GRASSO REFRIGERATION PACK

• Industrial refrigeration for large-scale cold storage facilities.
• Process cooling in chemical and pharmaceutical manufacturing.
• Freezing applications in the food and beverage industry.
• Air conditioning for large commercial or industrial buildings.

Typical refrigeration duty

Units of this class commonly offer duties from 150kW to over 1000kW, depending on the specific model and application parameters.

Refrigerant type

Ammonia (R717) is a common refrigerant for high-capacity industrial systems due to its excellent thermodynamic properties and environmental profile.

Compressor type

Screw compressors are typically used in these packs for their efficiency, reliability, and suitability for varying load conditions.

Evaporating temperature range

Industrial refrigeration packs can operate across a wide range, with low-temperature applications commonly requiring evaporating temperatures down to -40°C or lower.

Power supply

Typically requires a robust 3-phase industrial electrical supply, commonly 400V/50Hz in the UK, with significant current draw.

Footprint

For this class of equipment, a significant plant room footprint is typically required to accommodate the compressor, motor, oil separator, and associated pipework.

• What are the common maintenance requirements for a used ammonia refrigeration pack?

  Regular maintenance typically involves oil analysis and changes, compressor overhauls at specified intervals, leak detection, and inspection of valves and safety systems. Ammonia systems require specialist technicians.

• Is ammonia (R717) a safe refrigerant for industrial use?

• What additional equipment is usually needed to operate a refrigeration pack?

• Can this unit be adapted for different evaporating temperatures?

• What should I consider regarding installation of a used refrigeration pack?

Industrial chillers are valued for reliable temperature control in food processing operations. Buyers typically prioritise units with consistent cooling capacity and minimal maintenance history when purchasing used equipment. Key considerations include compressor condition, refrigerant type compatibility, and ease of spare parts availability. Industry sentiment favours models from established manufacturers known for durability. Common strengths include energy efficiency improvements in newer models and adaptability to various production scales. Proper installation and routine servicing remain essential for long-term performance.
