Barrel Pump Unit
●Safe and leak-free, efficient and reliable
●High-pressure internal circulation prevents liquid from vaporizing
●Automatic oil return improves system efficiency
●It can supply liquid over a long distance, and the efficiency of full liquid supply is about 30% higher than that of direct expansion liquid supply.
●Expand the operating range and upgrade the motor temperature to NTC configuration

Application Case
2022 Winter Olympics Venue (National Speed Skating Stadium)
Refrigeration host:
The system configuration uses 6 CO2 transcritical parallel compressor units, each unit uses 6 compressors to meet the cooling capacity requirements of the project's transcritical ice pouring conditions.
Gas cooler: The system configuration uses 6 CO2 cooling gas coolers to meet the cooling needs of all equipment in the project;
The barrel pump unit: The system uses four 14m³ CO2 barrel pump units independently developed by ARKREF and is equipped with a dedicated low-temperature circulation pump for CO2 to meet the system cooling capacity and CO2 storage requirements.
