GTEC Evaporative cooler


As the global demand for energy rises, the role that gas turbines play will be more and more important. Gas turbines are convenient, modular and flexible and can address demand for an increased energy baseload capacity. However, rising ambient temperatures have a negative effect on gas turbine power output. With the use of Munters well-established and tested evaporative cooling technologies the effects of ambient temperature on gas turbine output are countered.

These technologies can be applied to newbuilds as well as being retrofitted. Knowing which one will work best for you can be advised by Munters experienced team to provide cost-effective technology that is flexible and without adverse downstream effects such as pressure loss or corrosion.

The Benefits of pre-cooling for gas turbines

  • Ensure turbines operate efficiently – whatever the climate
  • Reduce or eliminate the need for additional turbines
  • Predictable power output at all times
  • Run turbines with optimal efficiency
  • Easy retrofit and installation
  • Increased power output
  • Enhanced fuel efficiency
  • Short payback

Munters Evaporative Cooling Media Technology
Our structured approach to temperature control is extremely cost-effective and quick and easy to implement.

Water is distributed downwards through a cooling media upstream of the gas turbine inlet at a controlled rate. The inlet air passes through the media (specifically designed to minimise pressure loss) and the water is evaporated to a cold vapour, chilling the air that passes to the turbine and increasing power output as well as the operating efficiency.

Get it right – first time
Get it right and you can ignore the temperature rise. Get it right and you can increase power output, eliminating the need to invest in new or additional gas turbine power generation. Get it right and you can ensure your gas turbines are always operating under optimal operating conditions, so they don’t have to work so hard, potentially extending their service life and minimising the maintenance requirement. Get it right and you will also save cost on filter replacement and reduced blade erosion.
