the operator ' s objective that the refurbishment be carried out during the operational break in May / July 2021 . By September 2019 , the planning could be completed in this respect and handed over to the client . With the documents , explanatory reports were written for the requested funding sources in order to transparently present the conversion measures . The state of Thuringia and the federal government then reviewed the documents and approved the funding in 2020 . With the release of the funds , the specifications for the conversion measure ’ s compressor replacement and new construction of control technology could be drawn up and published in the fall of 2020 . The contract was then awarded to Gesellschaft für Kälte- und Klimatechnik , Cologne , in a public tender in February 2021 . In mid-February 2021 , the concrete implementation began . In the course of work preparation and ordering , it was possible to quickly start clarifying all relevant boundary conditions for a smooth rebuild . This was done with a clear project schedule , drawn up and followed up by the engineering firm Möller & Meyer . On May 4 , 2021 , the old cooling generation plant of the Erfurt Ice Sports Center was decommissioned . However , this did not happen overnight . Thanks to the targeted efforts of all the companies , planners and builders involved , the complete conversion of the facility was completed on August 23 , 2021 .
GEA solution GEA supplied three SP1 SB-5A single-stage screw compressors for refrigeration at the Erfurt Ice Sports Center . The GEA Grasso SP1 series of single-stage screw compressors are designed to meet highly individual needs from medium to the largest cooling capacity ranges . The

Screw compressor package with GEA Omni control panel
SP1 series consists of 16 models ranging from 524 kW to 7,721 kW ( R717 | -10 / + 35 ° C | 3,600 rpm ) cooling capacity . The Grasso SP1 series is particularly attractive because of its versatility , whether in the food industry or in a high-pressure version for CO2 in a heat pump system or in an explosion-proof version for chemical applications . GEA customers can choose from a wide range of options and tailor packages to meet all individual needs . And here , the choice of the Erfurt Ice Sports Center and all project partners fell on the use of three SP1 SB-5A single-stage screw compressors .
Omni Control Panel The " command center " of the refrigeration plant at the Erfurt Ice Sports Center also relies on GEA technology . The GEA Omni Control Panel is designed as an open system . This means that it can be used to monitor and control not only the relevant components from GEA , but also components from other suppliers . As a universal command center , the customized GEA Omni system works closely with the S7 control system . The control panel displays operating statuses not only for main components , but also for auxiliary equipment . Operators at the Erfurt Ice Sports Center can control the entire cooling system from a single control panel - whether for monitoring and managing primary equipment such as compressors , condensers , vessels and evaporators , or the position of individual valves and pumps . The GEA Omni System Control Panel also has integrated energy management functions . For the operators and users at the Erfurt Ice Sports Center , GEA Omni offers everything operators expect from a control panel : maximum efficiency and reliable operation of their facility . This advanced , industrial control panel optimally integrates and coordinates all necessary system components , resulting in a demand-driven , highly energyefficient operating plant , coinciding with all the necessary qualities of the ice center .
