Grasso Compressor

• Industrial refrigeration systems for cold storage and food processing.
• Providing cooling for large-scale air conditioning systems in commercial or industrial buildings.
• Use in chemical processing plants requiring precise temperature control.
• Supporting freeze-drying processes in pharmaceutical or food industries.

Compressor Type

Typically a reciprocating or screw compressor, designed for refrigeration duties.

Refrigerant Type

This unit uses Freon. Modern equivalents often use HFCs or natural refrigerants, but Freon units are still operational.

Cooling Capacity

For this class of equipment, cooling capacities typically range from 50 kW to several hundred kW, depending on the specific model and application.

Power Supply

Commonly 400V/3-phase/50Hz for industrial applications in the UK, with motor power typically ranging from 30 kW upwards.

Associated Equipment

Often supplied as part of a larger system, including a condenser (like the mentioned Baltimore unit), evaporator, and control panel.

Footprint

A compressor unit of this type, with motor, can typically occupy a floor area of 1.5m x 1m to 3m x 2m, excluding the condenser.

• What does 'Freon' mean in this context?

  Freon is a brand name for several halogenated hydrocarbons used as refrigerants. While some specific Freon types are phased out, the term often refers to various HFC or HCFC refrigerants still found in older systems.

• Is a Baltimore condenser suitable for this type of compressor?

• What maintenance is typically required for a used compressor?

• Can this compressor be used for applications other than a belt freezer?

• What should I consider regarding installation for a unit like this?

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.
