Why Choose a Quality Low Pressure Sewer System from Delta


DFC FLOAT CONTROLS
DFC float controls by Delta Environmental Products, is an innovative approach to today's pump control system requirements with standard features unmatched by most competitors. Through the use of a standard sub-door and raised back panel. Delta Environmental offers a revolutionary design for housing common control panel features such as circuit breakers, start components, contactors and a terminal strip. Some standard features include: lockable latches, a flashing red alarm light with an electronic horn, and the innovative touch to silence pad all in a NEMA 4X enclosure. In addition to unsurpassed standard features Delta Environmental offers an exclusive control circuit board. Conveniently located on the Sub-Door the float indication lights allow the user to see the status of each float and flashes should a float fail.
Float Systems provide for accurate On/Off/Alarm liquid level control in sewage environments. These float switches can also be utilized for direct alarm activation on separate alarm systems.

DPC PRESSURE BELL CONTROLS
DPC Pressure bell controls by Delta Environmental Products, allow the user to change all settings and adjustments outside of confined space with no electrical level system components in wet areas, no cords to tangle or adjust, no mercury, no mechanical switches to fail, no probes to corrode, and no venting required. These systems combine the features of a pressure transducer, a pump controller with remote level settings and manual test / run switches, as well as battery backed up audible alarms. The duplex systems also include built in alternation, ten second lag pump delay, and separate lag pump on level setting. Because the pressure systems use the pressure bell to operate, they exceed intrinsically safe Class 1, Division 1 standards. The pressure bell transmits a pressure only signal to the controller so no voltage from the level sensing device enters the wet well. As the water level rises in the basin, pressure is created in the pressure bell sending an air only signal to the controller. The higher the level in the basin gets, the more pressure that is created in the pressure bell. Through the use of a control circuit board, conveniently located on the Sub-Door, this system allows the user to adjust all settings to precise levels, in inches, by simply turning a knob.

The pressure bell liquid level systems allow the user to change all settings and adjustments outside con. ned space with no electrical level system components in wet areas, no probes to corrode, and no venting required.

The pressure bell liquid level is nonelectric and transmits a pressure only signal to the controller. No voltage from the level-sensing device enters the wet well. As the water level rises in the basin, pressure is created in the pressure bell sending an air pressure only signal to the controller. In fact, installation of the pressure bell is as simple as mounting the bell and connecting it to the control panel using the provided 50 of " poly tubing.

Through the use of a control circuit board conveniently located on the sub-door, this system allows the user to adjust all settings at precise levels by simply turning a knob.
