One Pod at a Time

There’s no Submer without sustainability. Driven by our mission to build sustainable datacenters and lead the way to a greener future, minimizing our environmental impact is at the heart of every decision that we make.


Planet-Friendly Cooling

The sustainable benefits of immersion cooling are the best way to hit your sustainability benchmarks and build a climate-resilient datacenter. 

  • Reduce Energy Consumption

    Bring your mPUE down to 1.03 and PUE to 1.1 with our immersion cooling solutions. 

  • Reduce Water Consumption

    With a 1MW DC using 6.6 gallons of water per year, it's time to leverage our solutions to reduce both your direct and indirect water consumption. 

  • Heat Reuse Capabilities

    Immersion cooling offers 100% heat capture from liquid in direct contact with your equipment, marking it as the best cooling technology for datacenter heat reuse. 

  • Biodegradable SmartCoolant

    Our biodegradable immersion cooling fluid has a lifespan of 15 years and a Global Warming Potential (GWP) of 0. 

  • Optimize HW Lifespan

    The removal of moving parts, dust, vibrations, and sudden temperature changes equates to a more stable environment for your hardware. 

  • Optimize Space

    Increase your density per square foot by up to 361 kW per tank for both greenfield and brownfield scenarios. 

  • Building a Green & Efficient Datacenter Industry

    The sustainable benefits of immersion cooling reach far and wide. In 2023 alone, our customers minimized their CO2, energy and water footprints by leveraging our immersion cooling technology. 

    Energy Savings

    527 Megawatt-Hours 

    Energy savings with customers PUE where available; default PUE is 1,1 compared to 1.55 for air cooling.

    Uptime Institute

    Water Savings

    • T.Loop Leverages High Heat Dissipation & Heat Reuse

      T.Loop’s first Data Energy Center®, DEC001, launched in 2023 at the Factory in Stockholm, utilizes immersion cooling by Submer. This technology offers superior heat dissipation due to the liquid's high thermal conductivity, reducing noise and energy consumption compared to traditional air systems. It also protects against contaminants, minimizing thermal stress and extending equipment lifespan. Ideal for advanced technologies like AI and machine learning, immersion cooling enhances both performance and reliability. T.Loop shares a commitment to sustainability with Submer, using recovered heat to warm our building, thereby improving energy efficiency, and creating a more environmentally friendly data center solution.

    • Is immersion cooling sustainable?

      Immersion cooling is the most sustainable form of liquid cooling:

      • It reduces power and direct & indirect water consumption, therefore reducing CO2 emissions.
      • It lets your infrastructure operate at higher temperatures, providing more free cooling time.
      • Higher power density leads to less real estate needed.
      • Immersion cooling fluid is non-toxic, biodegradable, GWP=0, and it can be recycled.
      • It protects the hardware from degradating agents such as dust, moisture and vibrations, which plays in favor of its lifespan.

    • Is single-phase immersion cooling fluid toxic?

      Submer’s validated fluids are non-toxic, synthetic fluids designed for immersion cooling. Some handling and operation guidelines must be taken into consideration, which are detailed in the safety data sheets.

    • How does immersion cooling reduce water wastage?

      The fact that the cooling infrastructure can operate at higher temperatures provides more opportunities for free cooling, therefore direct water consumption can be reduced to zero (depending on the location and operating conditions).

      More efficient and less demanding cooling infrastructure leads to reduced energy consumption, which positively affects the indirect water consumption. Keep reading about immersion’s effect on water consumption here.

    • How do I implement heat reuse in my immersion-cooled datacenter?

      Virtually all the heat generated by the IT is transferred into a single body of immersion fluid, which will be circulating through one of the sides of a liquid-liquid heat exchanger. The heat is transferred to a closed water loop circulating on the other side of the heat exchanger. This hot water can be used straight away for heat reuse applications if its temperature is high enough – depending on IT hardware selected and operating conditions – or it can go through a Heat Recovery Unit (HRU), which is a equipment designed to guarantee optimal energy recovery by adjusting the water temperature.

      Depending on the availability requirements of your datacenter and the SLAs with the heat offtaker, a standard heat rejection system may be needed.
