Customer Benefits

Energy Efficiency: Industry spends more money on the energy to power its compressed air systems than on any other part of the manufacturing and process applications. With energy use accounting for roughly 80% of the total cost over the life of the compressor, creating energy-efficient solutions for industrial use is a priority at Belliss & Morcom. Our reciprocating air compressors offer up to 10% lower energy consumption than comparable screw compressors through lower specific power requirements and more efficient load and unload cycles. This translates to significant cost savings, with potential annual savings of up to £20,000. 

Longevity: Belliss & Morcom compressors are built to last, with a design life of up to 25 years without the need for major overhauls. This long lifespan ensures dependable performance and reduces ongoing capital expenditure. Additionally, our compressors are designed for ease of maintenance, with extended service intervals of up to 8,000 hours. This minimizes downtime and maintenance costs, providing total peace of mind and maximizing productivity. 

Total Cost of Ownership: Our compressors deliver up to 33% savings on total cost of ownership over 10 years. This is achieved through superior energy efficiency, reduced maintenance requirements, and the elimination of air end replacements. By choosing Belliss & Morcom compressors, you benefit from lower operational costs and a tangible return on investment. 

Reliability: Belliss & Morcom compressors are engineered to provide reliable air delivery even under demanding conditions. Our unique design features and engineering refinements ensure consistent performance, greater uptime, and reduced energy consumption. This reliability is crucial for maintaining continuous production and minimizing operational disruptions. 

Ease of Maintenance: Our compressors are designed with wear reduction and ease of access in mind. All wearing parts are easy to access and work on, reducing service complexity and downtime. Regular and scheduled maintenance is straightforward, allowing for ease of budgeting and ensuring that your compressor remains up and running efficiently. 

How Our Compressors Work?

Belliss & Morcom compressors are designed with a unique combination of features that ensure maximum efficiency, reliability, and ease of maintenance. Here’s how our compressors work to deliver outstanding performance: 

  • Shaftless Motor Technology: Our compressors are equipped with shaftless motors, which eliminate the need for belt drive systems. This means 100% of the motor’s output power is transferred directly into the compressor’s running gear, with zero degradation over the lifetime of the equipment. This results in significant energy savings and reduced maintenance costs. 

  • Diagonal Cylinder Design: The unique diagonal design of our compressors ensures that each compression stage runs on its own cylinder line. This design reduces static piston ring loading by up to 29.3% compared with horizontal cylinder lines, minimizing wear and eliminating the need for interim turning of compression or bearing rings. This leads to longer service intervals and reduced downtime. 

  • Water-Cooled Motor Protection: In harsh environments, our bespoke water-cooled motors eliminate the risk of de-rating or failure associated with air-cooled motors. With IP56 protection and a cooling system that doesn’t rely on or impact the surrounding environment, our water-cooled motors can run reliably where air-cooled motors cannot. 

  • Compact Footprint: The diagonal design of our compressors makes them significantly more compact than competitors’ equipment. This means more air delivered for a given amount of factory floor space, allowing for valuable extra space for productive activity. 

  • Ease of Maintenance: Our compressors are designed for ease of access and maintenance. Key components are easy to access and work on, reducing service complexity and downtime. This ensures that your compressor is up and running quickly, maximizing uptime and productivity
