The KEV series regulators feature a heating element that is in direct contact with the process fluid for maximum thermal efficiency and is removable for easy cleaning. It can be mounted horizontally or vertically and the one-piece body eliminates potential leak paths.

KEV series regulators are ATEX, IECEx, and CSA certified for critical/hazardous environments as listed in the product catalog and have a T3 temperature classification for all heater ranges.

Maximize your system’s effectiveness and minimize costly downtime.

Responding to Changes in Operator Input

Prevent shutdowns due to overheating caused by fluctuating operator inputs with the embedded temperature sensor.

Responding to Changes in Ambient Temperature

Help prevent blown fuses and overheating with the embedded thermal switch that automatically resets when ambient conditions change.

Reacting to Changes in Thermal Load

Ensure uninterrupted operation with integral control that enables quick response to deviations from system conditions.
