Additional safety accessories are available for added safety when used in the most critical applications.
Materials
in contact with the materials, including PVC, ceramic, PTFE, 316 s / steel, Hastelloy C, GFRPP and PVdF are available to treat nearly all chemical lessolutions. Pipe connections are used for quick and easy installation.
Control Modes EWN-R / EWN-Y EH-E Series
The standard model EWN-R now combines comprehensive functionality for either a manual or automatic operation in a single range: Manual control capacity with either automatic or external pulse stop, or; Programmable automatic control either 4-20 mA, preselection counter or proportional pulse. Pulse fracture / functions multiply with alarm output (EH-E only), detection alarm rate and failure, reading rate in two liters / hr or min.
Capacity
10 of 12 models cover the maximum capacity of 0.7 from 2.28 to 75.0 liters / hour and discharge pressures up to 10 bar. Range of coverage from 720: 1 to 9.001.800: 1 (depending on the model) is available using a combination of manual racing length and automatic control of the running frequency.
Additional variants for the specific needs
EWN-A type – with a high compression / automatic degassing head lapompe for gassing chemicals such as sodium hypochlorite.
Type EWN-Y – includes all features of the EWN-R standard, as well as self-calibration capability, real-time reading flow when used with the EFS flow sensor incorporating feedback control. Simple flow monitoring functions can be obtained by using FCM or FCP flows optional controllers to detect abnormal flow conditions. Standard alarm and analog output functions provide additional options for flow checking.
The EWN-A self-degassing valve can be combined with the EWN-Y with EFS for complete self-calibration, self-degassing solution with fast automatic selection capability
Accessories
Anti-siphon valves charging, the flow detection with alarm output, automatic bleed valves, various connections.
