Delta-p®

Product catalog summary
Overview: The Delta-p® is a triple water softener system designed to provide a continuous supply of soft water without pressure loss. It features a patented control valve, electronically controlled blending, and is cost-effective. Suitable for both residential and industrial use, it is certified by DVGW.
Specifications: The system operates with capacities ranging from 3 to 80 m³ and is available in nominal diameters of 1”, 1 ¼”, 1 ½”, and 2”. It maintains a low pressure loss of less than 0.8 bar for efficient operation.
Functional Principle: Utilizing three exchanger tanks, two operate in parallel while the third regenerates, ensuring a continuous supply of soft water. A central control valve ensures symmetrical distribution of raw water to the tanks.
Ion Exchange Process: Hard water passes through a tank with cation exchanger resin, where calcium and magnesium ions are exchanged with sodium ions, softening the water until the resin's sodium ions are depleted.
System Types: Available in single, twin, and triple systems, the triple system increases capacity with an additional exchanger tank for uninterrupted operation.
Installation and Operation: Designed for easy installation and operation, the system includes an electronically controlled blending device for precise hardness adjustment, complying with DIN standards.
Construction and Hygiene: Complying with DIN EN 14743 and DIN 19636-100 standards, the design minimizes pressure loss and eliminates dead zones for hygienic operation.
Optional Accessories: Optional features include a low-on-salt alarm, connection sets, and pedestals for easy installation. An industrial version is available without a blending device.
Performance Data: Nominal flow rates vary by size, with maximum continuous flow rates decreasing with higher raw water hardness. The system is designed for efficient operation with minimal salt and water consumption.

Triple water softener Delta-p® Triple water softener Delta-p® Water softeners working according to the ion exchange process have been well proven state-of-the-art for several decades and have been used mainly in large housing estates, building complexes or industrial applications with high water consumptions. Pressure losses during softening and the considerable efforts regarding installation and dimensioning of the systems always turned out to be disadvantageous, however, with the new triple water softener Delta-p®, Grünbeck Wasseraufbereitung GmbH has found an entirely new solution to this...

Triple water softener Delta-p® In general, the exchanger tank can only soften the water for a specific time and then needs to be regenerated prior to resuming the process again. This fact resulted in the development of the following basic system types: 1. Single systems: They have only one exchanger tank. No softened water is available during the regeneration process but hard water may be provided in terms of an emergency supply. 2. Twin systems: Two exchanger tanks are used. While one tank is in regeneration, the other is in operation. As soon as the operating tank is exhausted, the modes are...

Triple water softener Delta-p® Water softening at the lowest pressure loss possible (< 0.8 bar) The following parameters allow this simple selection: The principle of the ball valve in the water softener Delta-p® does not only ensure the exact symmetry between all three exchanger tanks, but it is also proven to be the valve construction with the lowest pressure loss. This is due to the fact that it consists of only one switchable pipe without any narrow spaces. In addition, the height of the exchanger tanks was kept as low as technically feasible. Thus, all system components were dimensioned...
