PET Bottle Blowing - Every Detail Matters

In the competitive world of PET bottle blowing, every efficiency-gain and cost-saving matters. Every bottle matters, every second of every production run matters. And every cubic metre of compressed air matters. 

Building on decades of innovation, every Belliss & Morcom compressor is engineered from the ground up, to deliver outstanding levels of efficiency, quality and performance, specifically for PET.

A combination of unique design features and engineering refinement adds up to real advantages for customers – including reduced energy consumption, greater uptime, lower total cost, and the sheer reliability of air delivery, when the pressure is on.

Every One Percent Matters

In PET bottle blowing, success depends on fine margins, which is why machine efficiency matters. The unique Belliss & Morcom shaftless motor offers 100% drive efficiency to deliver the lowest system running costs in the industry. 

The smallest issues in the transfer of power from the compressor motor can result in significant energy loss, and serious financial impact. In fact, belt drive system inefficiencies can add up to 12% to energy bills. That is the reason why every Belliss & Morcom PET compressor is specified with a shaftless motor as standard.

As a result, 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. So you start by saving, and you continue saving, year after year.
