condensers( 10.8MW), high-pressure accumulators, economisers, separators and various consumer pumps. The plant supplies 6.3MW of power for an alcohol – water system for tank storage and utility cooling( temperature-8 ° C) and 2MW for a brewing water system with a storage unit to cool the brewing water( temperature 0 ° C). This provides cooling for the tank storage unit, the storage tanks and several production processes, as well as air conditioning for the production halls and data centre.
A provisional design by Heineken Supply Chain( the designer) was revised and improved by Johnson Controls Service GmbH, which was responsible for the implementation and commissioning stages. This led Paulaner( as the customer) and Heineken to revising the entire footprint of the plant. This plan will now serve as a blueprint for further brewery construction projects.
The customer, the designer, the companies involved in implementation, and the testing organisations all worked closely together to ensure the project could be completed on time and within the specified budget, with constant monitoring of the schedule and implementation process. The plant design pays particular attention to ensuring that on-site employees can operate it without difficulty( for example recording operating hours for all drives to optimise maintenance work; an error app from Johnson Controls for on-site troubleshooting and fault rectification; comprehensive on-screen displays; and

Category: Commercial refrigeration Project: R134a / R744 cascade for walk-in refrigerators and freezers at Cytec Solvay in Östringen A new freezer with an upstream coolroom was implemented for Cytec Solvay in Östringen. The coolroom is cooled to + 4 ° C and the freezer to-23 ° C, respectively, using two R134a / R744( CO 2
) cascades installed in two technology containers on the roof of the building. Each cascade works as an independent system, providing 100 % redundancy. Even though it meant higher investment costs, a system using natural coolants was adopted. The technical features include a well thoughtout

oil management system, heating for condensation water basins and pipes, a gas warning system in the technology containers, container cooling with ductfree inverter evaporators, integration of the cascades in a process control system with measurement data trend recording, archiving of error messages, and a cascade display via a touch panel. Besides using PLCs, the plants were also fitted with a monitoring system that ensures even greater plant availability, efficient operation and optimised maintenance. Structural parameters meant that the rooms could be cooled only gradually by 3K per day( that is, 14 days were needed to reach the target value in the freezer). This was controlled using the Rütgers monitoring system.
The technical requirements were worked out in detail by the designer
