BITZER Ammonia Packs Provide 1.4MW of Cooling for Huge New Pizza Production Facility

Date: 03 January 2019

Two BITZER Ammonia Compressor Packs (ACP) with a combined cooling capacity of 1.4MW are supplying high performance, high efficiency refrigeration for a vast new pizza production plant in the North of England.

The industrial scale single-stage pumped ammonia system serves all the cooling needs of the brand-new 60,000sq ft food production facility. Carried out by Integral UK for one of the UK’s leading food companies, the installation uses the BITZER ACP systems to deliver multi-temperature cooling for the plant’s 2°C chill store, -5°C spiral chillers, -18°C freezer cold store.

The ACP units selected have three compressors per pack, giving standby capacity and resilience needed for such critical process applications. It enables engineers to service a compressor while the others remain operational, reducing process down-time and improving life-cycle cost.

ACP has been designed to meet the requirement for high efficiency cooling for industrial applications with a zero Global Warming Potential (GWP) refrigerant. In addition to its exceptional part-load efficiency, it enables rapid commissioning due to its plug-and-play design.

In addition to the inherent efficiency of screw compressors, the speed of the lead compressor is controlled by an integrated variable speed drive (VSD), which significantly increases part-load efficiency and enables soft-start. Efficiency can be further enhanced with the addition of an optional economiser module. 

A further benefit for end users is that screw compressors have much longer maintenance intervals than reciprocating compressors, which substantially reduces the cost of ownership over the life-time of the plant.
