The InRow Pumped Refrigerant product design closely couples the cooling with the IT heat load. This design prevents hot air recirculation, while improving cooling predictability and allowing for a pay as you grow environment. Available in overhead or floor mounted configurations, these products are designed to reduce power and whitespace consumption without introducing chilled water next to IT equipment. Data center operators looking to improve efficiency or deploy high density servers will benefit from the modular design of the InRow Pumped Refrigerant cooling products. The intelligent controls of the InRow Pumped Refrigerant cooling products actively adjust fan speed and refrigerant flow, with no minimum loading, to match the IT heat load to maximize efficiency and address the dynamic demands of today's IT environments.
