- [Desuperheater](https://croll.com/desuperheater/): Desuperheaters Return steam to its optimal, saturated state for heat transfer applications About Desuperheaters Although process steam is typically throttled and superheated for efficient distribution, it must be cooled before it’s condensed because it’s less efficient than the saturated steam for many heat transfer operations. The most efficient way to reduce the temperature of superheated steam is to “desuperheat” it, by bringing superheated steam into direct contact with pressurized cooling water sprayed in form of small particles. This steam desuperheater mist of cooling water particles is dispersed using specially designed spray nozzles to maximize efficiency. The desuperheated steam is cooled through […]
