Keep your Data Centre or Computer Room Cool with Evaporative Cooling Systems


Vent-Tech's innovative evaporative cooling systems cool air, without relying on expensive-to-run air conditioning, and are suitable for data centres, server rooms or computer rooms, where it is required, by:

  1. Cooling fresh air over water in the summer to provide cool air and then exhausting the hot stale air
  2. Mixing recycled warm air with cool fresh air from outside in the winter to reach the right temperature and reduce energy use

Substantially reduce the costs of expensive air conditioning in your Data Centre

Cooling Data Centres with Evaporative CoolingCooling costs are pivotal to data centre profitability. Vent-Tech's data centre evaporative air cooling installations slash these costs and are rigorously tested to keep business-critical computers, servers and hardware strictly within specified temperature and humidity ranges.

While evaporative data centre cooling systems are still a relatively new phenomena in the UK, globally their use is widespread – Google, for instance, use this technology in all of their data server centres.

The Benefits of Computer Room Evaporative Cooling (CREC)

1. Improved power usage effectiveness, so a greater proportion of electricity is used to run your computer server equipment (rather than running cooling systems)
2. Massive electricity bill savings: companies that have ripped out and replaced expensive-to-run air conditioning systems typically more than recoup their investment in eco cooling within a couple of years
3. Carbon emission reductions of around 90%

S3 now have a data centre cooling system that delivers fantastic savings and is great for the environment too. I fail to see any downsides to the system – it pays to be green!”

Savings from Evaporative Cooling vs Traditional Computer Room Air Conditioning (CRAC)

Typical Server Room being cooled using an Eco Air Cooling SystemVent-Tech eco air cooling systems outperform CRAC systems by a huge order of magnitude – here are the facts:

The most efficient CRAC systems (generally with variable fan speeds and free cooling facility) have a Coefficient of Performance (CoP) of 3.7, meaning that 3.7kw of cooling is produced for each 1kw of energy consumed. Standard air conditioning systems do not have these energy saving features, and have a CoP of around 2 or less.

By startling contrast, eco-cooling systems fitted by Vent-Tech have a CoP of 23.8, and consume only 1.5kw of energy to produce 35KW of cooling

Controlling the Humidity in your Server Computer Room

As a leading eco cooling supplier for computer data centres, we provide expert advice to clients on effectively controlling the humidity within their computer rooms. Humidity control set-up is a standard part of Vent-Tech’s rigorous installation and maintenance procedure, and we provide your operators with concise, clear training to ensure the most benefit is provided from our cooling systems.

Modern computer servers now operate in a broader range of temperature and relative humidity. Most machines specify a 10°C to 35°C operating temperature, while relative humidity is less important with old tape to tape and paper systems in much less use. Vent-Tech's Computer Room Evaporative Coolers ("CREC's") are proven to be able to maintain these standards, even in extreme outdoor temperatures without resorting to expensive-to-run air conditioning.
