The VariCool desuperheater integrates the precision of a control valve into a desuperheater to attain maximum range ability, responsiveness and control - coupled with the high-thrust FlowAct pneumatic diaphragm actuator.
The multi-stage design allows the VariCool to manage a wide spectrum of differential pressures (up to 90 bar/ 1305 psi) as it directly injects atomized cooling liquid to cool process steam.
Temperature reduction occurs as the atomized cooling liquid rapidly vaporizes into the process steam. The perforated, flow-to-close plug and nozzle design maintain accurate control of varying process conditions through precise throttling of the cooling liquid in response to feedback from a controller and downstream temperature sensor. Up to 14 kvs- /cv-values are available per size.The sturdy design minimizes vibrations and wear. The VariCool is capable of operating within temperatures ranging from -10°C to +530°C / 14°F to +986°F.
