Your benefits at a glance
The Pi Power Compact 450 is a powerful direct-flow reverse osmosis system for households, practices, and commercial applications with increased water demand. It filters tap water in real-time – completely without a storage tank. This means no standing water, ensuring maximum hygiene and significantly reducing the risk of germ formation.
Compared to the Compact 300, the 450 with three powerful osmosis membranes (150 GPD each) and higher filter performance provides a noticeably larger amount of water per minute – ideal if several people or devices need to be supplied simultaneously. Under an operating pressure of 9.5 bar, even the smallest pollutants are reliably retained. The result is highly pure osmosis water with a retention rate of up to 99%.
The system operates fully automatically: Permanent water quality monitoring (TDS measurement) ensures that the filter performance remains consistently high. Automatic flushing cycles regularly clean the membranes and protect the system from deposits and germs. Filter and membrane changes are indicated in good time via the touch display.
In its basic configuration, the Pi Power Compact 450 delivers particularly pure, low-mineral osmosis water. Remineralization or vitalization is not integrated but can be added at any time via external solutions or the retrofittable PI-Cell Vitalizer Special if required.
The UV module in your PI Power Compact 450 provides additional safety in the final purification step. A specially developed LED light irradiates the purified water with ultraviolet light, effectively eliminating any remaining germs or bacteria. This form of disinfection works entirely without chemicals and makes the water hygienically perfect.
The UV module was developed primarily for regions where germ contamination in tap water may be higher. In Germany, this is usually very low – however, the UV module offers an additional level of security for anyone who places particular importance on hygienic purity.
PI technology originated in Japan and aims to transform drinking water into a state that is as cell-friendly and natural as possible. It was developed based on decades of research into water quality, minerals, bioavailability, and the structure of water in living organisms.
PI water is characterized by the following principles:
PI water thus attempts to replicate the quality of natural spring water.
Das Ergebnis: Reines Wasser mit hoher Rückhaltequote von über 99 %.
The Pi Power Compact 450 is installed at the water connection where you want to draw water – usually in the kitchen. For installation, you only need a cold water connection, an electrical outlet, sufficient space for the filter, and a wastewater siphon.
In principle, you can install your Pi Power Compact 450 yourself. However, we recommend professional installation by our assembly service. This way, you ensure that everything is optimally connected – and you also receive a warranty on the installation.
