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
