No-Flow Devices

Ariel now offers a selection of factory-installed no-flow devices with varying capabilities, power options, and multiple hazardous area classifications. Installed on each primary distribution block for system protection, these factory-supported devices are available configured for integral battery or 24 VDC power. Each device carries a 12-month warranty and is classified by CSA, IEC, and ATEX for hazardous area installation.

Compressors with DNFTs can either use the no-flow switch to directly shut down the unit or use the included proximity switch with the package control panel to create customized control logic. Advanced panels can watch both the no-flow alarm signal from the DNFT and the proximity switch circuit, allowing customized alarms and shutdowns, as well as cycle time and oil consumption trending.

From a simple proximity switch through a programmable digital no-flow timer with LCD information display, we can meet your no-flow monitoring and control needs working through our Distribution Network partners.
