The first installation of BITZER’s Digital Network (BDN) in Ireland is providing high-level monitoring, system diagnostics, and optimization for an award-winning deli food specialist.
The BDN system is integrated into a new high-performance low-temperature pack, based on BITZER ECOLINE inverter-controlled compressors supplied by RSL Ireland Ltd.
new refrigeration system
The new refrigeration system replaced two 30-year-old BITZER condensing units and Searle evaporators operating on R-404A, which had come to the end of their working life.
The new pack was equipped with discharge ball valves, tee-pieces, and pipe connections in the factory, enabling it to be connected directly to the site’s existing heat reclaim system, based on three Eureka EX units that produce hot water for process and domestic use.
Real-time data viewing
The compressors are connected to the BDN Gateway via Modbus, with BITZER UK providing support
To ensure continuity of cooling during the replacement project, the existing plant was kept running while the new equipment was installed, pressure tested, evacuated, and commissioned, ensuring cold room temperatures were maintained until the existing system was switched off and decommissioned.
The compressors are connected to the BDN Gateway via Modbus, with BITZER UK providing support to integrate and register the system on the network, enabling all commissioning and real-time performance data to be viewed and recorded, and activating a three-year extended warranty.
built-in capacity
The system has a built-in capacity for future expansion to cater to growth in the end user’s business, with an additional space in the pack for a third BITZER ECOLINE compressor.
Paul Lynch, Technical Manager at RSL Ireland Ltd, said, “The client was sold on the idea of a BITZER-based solution because the previous plant had operated so efficiently and trouble-free for 30 years. The additional warranty enabled by connection to BDN also gives peace of mind, knowing from a service perspective what the plant will cost over the next three years.”
Operational efficiency
Paul Lynch adds, “BDN is a great tool and deserves to be widely adopted. It enables you to drill down and see what is happening both historically and in real-time – at the level of each compressor."
He continues, “Performance can be compared against the operating envelope for each unit, giving valuable insights into what is happening through the operating cycle. This enables you to optimize operations and further improve efficiency. There is no doubt it can save a lot of time and money.”
Refrigeration performance improvement
Kevin Glass, BITZER UK Managing Director, said, “The project is a great example of how useful BDN can be, both to contractors and clients."
He adds, "It opens up almost infinite possibilities for improving refrigeration system performance, reducing running and servicing costs, and minimizing the impact of cooling systems on the environment.”
user-friendly format
Kevin Glass continues, “The need to deliver these improvements has never been greater. The key is timely information about how systems are performing in the real world, and the ability to easily adjust and optimize them. BDN delivers this, and in a user-friendly format that is easy to understand and apply.”
