Free cooling with air

Swapping your cooling tower for a dry liquid cooler or an adiabatic cooler is a great way to eradicate the risk of bacteria growing in your water. In fact, more countries are making the change to a more hygienic system a legal requirement every year.

When a dry liquid cooled condenser is far away from the chiller, a high level of glycol is added in the system for it to function correctly. To solve this, we can install an intermediate plate heat exchanger and minimize this circuit. So, you can save on glycol and unnecessary cost!

Cooling with heat exchanger


When your dry liquid cooled condenser is far away from your chiller, extra glycol is used to make sure everything works correctly. The volume of glycol needed in this case is very high, and so is the cost. Installing a plate heat exchanger will substantially decrease the glycol circuit, reducing the volume and cost of your cooling system. On top of that, a plate heat exchanger will allow you to control the temperature of your protected loop to fit capacity and help avoid condensation on the outside piping.

Every loop in your system has a natural risk of condensation outside your media when the temperature contrast reaches it's dew point. This condensation can cause damage to the sensitive area inside your data center, so the more loops in your system, the more likely you are to have problems.

Cooling without heat exchanger


Glycol is used in systems where the outside piping is at risk of ambient temperatures dropping below 0°C/32°F. That said, there are still many benefits to reducing your loop volume, even if freezing the cooling media is not a risk for your system.

Shield your data center with heat exchangers

There are many risks that come with using liquid in your cooling system. So, it’s important to protect the white space in the cooling loops from contamination and minimize the risk of leakages around electrical servers.

At Alfa Laval, we are constantly improving the design of our heat exchangers to help alleviate these challenges. To make that dream a reality, we have combined our world-leading expertise in data center cooling with proven heat exchanger solutions. This is guaranteed to increase reliability without compromising on the high efficiency levels you need.

The benefits of a gasketed plate-and-frame heat exchanger

  • Volume isolation
  • Minimize the volume of glycol in your cooling circuit
  • Reduce the risk for condensation and damage inside your data center
  • Reduce the cost of cooling your production
  • Certified performance in accordance with AHRI regulations


Savings across many dimensions

Combining a dry or adiabatic air cooler with a well-designed gasketed plate heat exchanger is a great way to protect and improve the cost-efficiency and sustainability of your data center. For example, using AHRI performance certified heat exchangers can reduce your power usage effectiveness (PUE) by 1%. It will even decrease the carbon usage effectiveness (CUE) of your facility by the same amount. Plus, a heat exchanger will enable heat recovery, which inevitably means lower OPEX.
