Howden Ammonia Refrigeration Pack

• Large-scale cold storage facilities for food processing and distribution.
• Industrial refrigeration for chemical and pharmaceutical production.
• Blast freezing and chilling operations in the food industry.
• Breweries and distilleries requiring precise temperature control.

Typical capacity

Industrial ammonia refrigeration packs commonly range from 500 kW to several megawatts, with this specific unit offering 884 kW total capacity.

Compressor type

This unit features Howden screw compressors, known for their efficiency and reliability in continuous operation.

Refrigerant

Ammonia (R717) is the specified refrigerant, valued for its high efficiency and zero ozone depletion potential, though it requires specific safety protocols.

Configuration

Units of this type often feature multiple compressors (e.g., two high-side, one low-side) to provide redundancy and optimise performance across varying loads.

Power supply

Industrial refrigeration packs typically require a three-phase electrical supply, commonly 400V or 415V, 50Hz, with significant current draw.

Ancillary equipment

Such packs are usually paired with evaporative condensers (e.g., Baltimore VXC series), receivers, and control systems.

Maintenance

Regular servicing and maintenance are crucial for ammonia refrigeration systems to ensure safety, efficiency, and longevity.

• What are the primary benefits of ammonia refrigeration?

  Ammonia is highly efficient, has excellent thermodynamic properties, and is environmentally friendly with zero global warming potential (GWP) and ozone depletion potential (ODP). It is also generally more cost-effective as a refrigerant.

• What safety considerations are important for ammonia systems?

• Can this unit be integrated into an existing refrigeration system?

• What is the typical lifespan of an industrial ammonia refrigeration pack?

• What is the significance of having a spare motor?

• Is the Baltimore Condenser included with the refrigeration pack?

Cold rooms and refrigeration units are considered essential assets in food processing operations. Buyers typically prioritise reliability, energy efficiency, and ease of maintenance when selecting used models. Industry sentiment favours equipment from reputable manufacturers known for durability. Key considerations include checking refrigerant systems, insulation condition, and temperature consistency. Well-maintained units often deliver strong performance at reduced cost compared to new alternatives, making them attractive for budget-conscious operations seeking dependable temperature control.
