Backwash Device Type RSL-EKF



11.15

Wasseraufbereitung Application: For the fully automated backwash of closed gravel-filter-systems, e.g. type EKF, which are installed be-tween well pump and pressure boiler, and for the (available-for-retrofitting) automated regulation of the pressure cushion in the water boiler. Suitable for both retrofitting or third-party-installations. Consisting of: 1 backwash machine in plastic casing with integrated SIEMENS small-control-system for the

programming of backwash times, with hand-0-automatic-choice-switch 1 automatic backwash valve, connection 1 ½“ made of glass fiber reinforced PA-plastic, with

integrated magnetic pilot valve (directly controlled) with manual control and customizable flow limits

1* flap-float-valve made of plastic for installation in the boiler, with 3 m cable, connection ½“ outside, max. 6 bar (*2 switches with pressure-cushion-regulation-option)

Magnetic valve 230 V, 50 Hz. incl. check valve and installation material for automatic air back-feed in case of pressure shortage in the water boiler (pressure-cushion-regulation-option)

Equipment of the well pump and intermediate pump with their respective motor protection switch-es and a pressure switch on the boiler has to take place on site.

Characteristics of backwash device RSL / DPR for EKF: Freely programmable backwash times Increased operational safety and economical service thanks to consumption-dependent backwash Backwash in automatic or manual service Optimal utilisation of the available boiler volume for

gravel-filter-backwash High switching capacity of the pump (20 A / 4 kW) Easy installation and initiation Alarm output (optional) Item-Nr. without pressure-cushion-regulation: 705118 Item-Nr. with pressure-cushion-regulation: 705119

Image. RSL-EKF with pressure-cushion-reg. Functional Description: In delivery status, a time-controlled forced backwash is pre-installed to take place once a week, at 2.00 in the night, to ensure system hygiene. Depending on the used amount of water (adjusta-ble), an additional backwash takes place, also time-delayed at 2.00 at night, and if necessary even daily. If necessary, a backwash can also be initiated manually at all times. After initiation of the backwash, the pure water contained within the water boiler is flushed backwards through the opening of the automatic valve into the drain, until the laterally inserted flap switch in the boiler reacts and the backwash valve closes. Afterwards the well pump is turned on again as often as necessary until the turn-off pressure of the pressure switch is reached and the automatic valve opens again. The (changeable) number of these backwash runs is pre-selected at 4 per back-wash, regardless of the required duration. Accordingly, initiation of the system is easy and re-quires a minimal amount of adjustments. For the option with pressure-cushion-regulation a second flap-switch is installed at the top of the boiler, which automatically supplements a deficient pressure-cushion via a magnetic air valve. If a INDUWA-Oxidation-air-compressor is installed, it takes over and ensures the necessary pressure-air-provision. Otherwise, a customary, oil-free compressor station is necessary.



Air-Cushion-Regulation



11.15

Wasseraufbereitung

Application: For the automatic check and correction of the air cushion in pressure boilers of gravel-filter-systems. For the service and, in particular, for the proper backwash in gravel-filter-systems, a correct air cushion within the pressure boiler is essential, especially if an automatic backwash system is installed. Furthermore, unnecessary on/off-switching of the well pump is prevented, which goes easy on the pump. Correction of the air cushion is achieved by either a preexisting oxidation-air-compressor or an external (oil-free) compressor station. Consisting of: 1 terminal box made of plastic, for surface installation 110 x 110 x 65 mm 1 flow switch for water-level assessment, for installation in the boiler 1 automatic magnetic valve ¼“ made of brass 230 V, 50 Hz. 1 check valve ¼“ made of brass 1 plug-in-T-piece for 8 mm pressure hose, for installation in the oxidation line 1 PE hose 8 x 6 mm, ca. 3 m long, incl. 1 plug connection ¼“ x 8 mm Characteristics of air-cushion-regulation Fully automated Air cushion continuously checked and corrected Always available for retrofitting, in all available

systems Easy assembly

Item-Nr.: 705035

Functional Description: The float valve is built into the pressure boiler from the outside, at appropriate height. (Sleeve exists in appropriate height on every standard boiler). During the filling of the pressure boiler, the float valve checks whether the filling level exceeds the target level. If the maximum filling level is exceeded during the automatic filling, a magnetic air valve is opened automatically, until the well pump is turned off again via the pressure switch. During this time, either the compressor for oxidation air or an external unit sends air into the boiler. This process is repeated until the float switch does not react anymore und thus enough air is contained within the boiler.



OKF-Level Control



11.15

Wasseraufbereitung Application: For the control of a well pump in pressureless gravel-filter-systems via a dynamic-pressure-membrane-switch. Functional description: The intermediate pump, which sucks the water from the pressureless filter container, is turned on and off by the pressure switch on the pressure container. As a result, the water level in the OKF-container decreases repeatedly and has to be refilled by the well pump. Since the well pump constantly delivers more fluid than the intermediate pump sucks off, the well pump has to be turned on and off again and again. This pump control takes place via a height-adjustable dynamic-pressure-tube, which is immersed into the container from above, in combination with a stationary membrane-pressure-switch (ca. 10cm hysteresis). The well pump is switched on and off directly by a contactor, with a maximum switching capacity of 20 A. The motor protection switch for the well pump is to be provided on side. Consisting of: 1 terminal box made of plastic, for surface installation 200 x 200 x 120 mm 1 230 V contactor, 3 turnkeys up to 500 V 1 automatic magnetic valve ¼“ made of brass 230 V, 50 Hz 1 check valve ¼“ made of brass 1 plug-in-T-piece for 8 mm pressure hose, for installation in the oxidation line 1 PE hose 8 x 6 mm, ca. 3 m long, incl. 1 plug connection ¼“ x 8 mm Characteristics of OKF-level control Fully automated Universally applicable for different systems and

manufacturers High switching capacity Easily programmable Easy assembly

Functional description of the backwash device: In delivery status, a time-controlled forced backwash is pre-installed to take place once a week, at 2.00 in the night, to ensure system hygiene. Depending on the used amount of water (adjustable), an additional backwash takes place, also time-delayed at 2.00 at night, and if necessary even daily. If necessary, a backwash can also be initiated manually at all times. After initiation of the backwash, the pure water contained within the water boiler is flushed backwards through the open-ing of the automatic valve into the drain, until the laterally inserted flap switch in the boiler reacts and the backwash valve closes. Afterwards the well pump is turned on again as often as necessary until the turn-off pressure of the pressure switch is reached and the automatic valve opens again. The (changeable) number of these backwash runs is pre-selected at 4 per back-wash, regardless of the required duration. Accordingly, initiation of the system is easy and requires a minimal amount of ad-justments.
