NX Filtration uses residual heat from data centre for its new megafactory

Provider of hollow fibre nanofiltration (NF) technology NX Filtration has entered into an agreement with Dutch IT solutions provider Previder — part of Odin Groep — to source residual heat from Previder adjacent data centre for its new megafactory. This is the first peer-to-peer heat exchange between a data centre and an external user in the Netherlands, that reduces CO2 emissions of both parties.

NX Filtration is in the process of constructing a new mega factory for the production of its hollow fibre NF membranes in Hengelo, the Netherlands. NX Filtration NF membranes combine the removal of small contaminations such as per- and polyfluoroalkyl substances (PFAS) or pharmaceuticals, with strong sustainability benefits, as they reduce energy consumption and avoid the use of pre-treatment chemicals.

NX Filtration new mega factory is scheduled to start up in the first half of 2024

Through the agreement with Previder, NX Filtration replaces the traditional primary source for its heat requirements, being high yield heat pumps and natural gas, with residual heat from the data centre. A new 300m underground pipeline will transport the residual heat from the data centre to NX Filtration, and at the same time bring back cold water from NX Filtration for the data centre cooling requirements. As both parties run a 24/7 operation, this provides a stable source of heat and cooling, reportedly avoiding a significant amount of CO2 emissions.

NX Filtration CEO Jeroen Pynenburg said, “This unique heat exchange agreement with Previder adds to a broader set of sustainability initiatives that we are implementing at our new factory, and enables us to avoid the usage of fossil fuels in our production processes.”

This peer-to-peer heat exchange agreement complements a broader set of sustainability initiatives that NX Filtration is implementing with the construction of its new mega factory, that includes the installation of more than 400 rooftop solar panels, the use of high yield heat pumps, and an extensive heat recovery system that enables the reuse of heat from internal sources such as wastewater streams.
