Kromschroder Relief Pressure Regulators VAR

Relief Regulators VAR is the  pressure regulators for combustion equipment and systems.

Relief pressure regulators for maintaining constant pressures in gas consumption equipment or for relieving brief pressure surges in control systems, in particular upstream of large-scale burners, circulation pressure control regulators for compensating for pressure fluctuations occurring on compressors or fans as the result of different flow rates.

Compressors and fans generate different outlet pressures in the case of different capacity demands. These fluctuations can be controlled by discharging a bypass flow from the outlet to the inlet of the compressor unit. Downstream consumers thus dispose of constant pressure over the entire capacity range.

The pressure regulators comply with the requirements of EN 88, Class A, Group 2
