The distribution of the refrigeration production reduces the charge of the main refrigerant and therefore the risk of leakage. The refrigeration production is decentralised, so that the condensing loop contains only water in a closed circuit with low hydraulic pressure. Simple installation Adaptation to the performance and needs of each system. Energy saving. The units integrate a system that adapts to the demand of the installation, and therefore energy savings. The waterloop system is applicable to new and existing centralised direct expansion installations. The system is easily adaptable to changes in service provision. Unlike others, waterloop is designed to work in climates with high temperatures, without the need for additional refrigeration systems.
