3-4000 series desuperheaters are almost solely used to reduce the steam temperature by directly injecting water inside the superheated steam flow.

• The above series includes 3-4100 variable area and 3-4500 fixed area models. LV variable area series, including LVL, LVP and LVM models, allows to solve the most common desuperheating problems without practical limits in flow rate and operating conditions.
• Fixed area LF nozzles, on the contrary, are designed for limited power processes with limited load changes.
