The range of EWD electronically controlled condensate drains is synonymous with safe, dependable and economical condensate management. The intelligent drain function monitors condensate build-up with liquid level sensors and evacuates only when necessary, thus avoiding wastage of compressed air and giving considerable energy savings.
Scope of Supply
- Electronically Controlled Condensate Drains
- Reliable electronic sensor
- No air loss of compressed air upon draining
- High energy efficiency
Options (available for the EWD75 and above)
- Hard-coating for oil-free and aggressive condensate
- Alarm mode
- Thermostatically controlled heater
- Insulating shells
The working principle
As condensate forms in the system, it is transferred to the EWD drain where it gathers as shown in Figure 1. Once the level of condensate within the drain reaches such that is recognised by the Electronic Sensor, Figure 2, the Outlet Valve opens to allow the condensate to drain from the system. Once the level of condensate reaches that as in Figure 1, the valve closes, leaving some condensate within the drain but most importantly preventing any of the compressed air from escaping.
Control and Monitoring
The draining of the EWD is controlled by a reliable electronic sensor which prevents any loss of compressed air. Monitoring takes the form of an alarm contact which activates in case of failure or a blockage in the drain pipe.
EWD fitted with a reliable for sensor control of evacuation with option of hard-coating and corrosion resistance to increase longevity and reduce maintenance. Insulating shells and thermostatically controlled heaters are available as options to suit the drains to low temperature environments.
