Desuperheater Inquiry Information

Most desuperheating applications can be accommodated with one of our three designs:

SA - Steam-Atomizing desuperheaters can handle large flow variations at a reasonable cost. Recommended whenever atomizing steam is available.
SV-1 - Double-Venturi desuperheaters are our most commonly sold style and can accommodate most desuperheating applications.
SV-2 - Single-Venturi desuperheaters have limited capability and a very low cost.

The table below can help you determine if a Graham desuperheater can accommodate your requirements. Fill out the Desuperheater data sheet and submit your inquiry to Application Engineering. We will quote within 3-5 days, sooner if needed.
