Drain technology

Drainage for inside and outside

facilities must be created for the collection and discharge of wastewater. We can
offer you everything that you will need with our wide range of drains and
channels for commercial and private applications. Our products are characterized

Grease Separators

The professional separation of greasy gray water
Grease and oil get into the wastewater of many catering and food-
processing businesses (e.g.restaurants, hotels, motorway services and
butchers). The wastewater has a long way to travel before it reaches
the next wastewater treatment plant. A quantity of grease and food
residues deposits in the drainage systems. The consequence is pipe
blockage, corrosion and odour nuisance and impairment of the function of
wastewater treatment and lifting stations. Therefore, the legislator requires
grease separators to EN 1825 or DIN 4040 be installed in businesses in
which greasy water is produced

Grünbeck sediment filters are designed to protect building water systems
by removing particles such as sand, rust, and dirt from incoming water.
These filters use fine mesh stainless steel screens to trap sediments while
allowing clean water to pass through. A key technology used is the
backwash function, which automatically cleans the filter screen by reversing
the water flow, flushing out trapped particles without needing to
disassemble the unit—ensuring continuous protection with minimal
maintenance. Grünbeck’s best-selling sediment filter products include:

pureliQ – Ideal for residential use, featuring a modern design, easy filter
changes, and hygienic protection.
GENO® backwash filter FS-B – A robust, self-cleaning backwash filter
for larger systems or commercial use.
Boxer® R and RD – High-performance filters with manual or automatic
backwashing, suitable for both homes and commercial buildings.

Water Softeners
Grünbeck’s water softeners, such as the softliQ series, utilize advanced
ion exchange technology to effectively remove calcium and magnesium
ions from water, preventing limescale buildup in pipes and appliances.
These systems intelligently adapt to household water consumption
patterns, ensuring efficient softening while conserving salt and energy.
Notable models include the softliQ:SD18, designed for households
of 1 to 4 people, and the softliQ:SC23, suitable for up

Grünbeck offers advanced UV disinfection systems such as the violiQ:UV,

making it an eco-friendly and reliable solution for safe water. Additionally,
Grünbeck’s GENO-break® system combines ultrasonic and UV technology
to effectively combat Legionella and other bacteria in hot water systems,
providing an extra layer of protection in sensitive environments like
hospitals and residential buildings. These systems are easy to install,
feature continuous monitoring, and ensure hygienic, chemical-free water
disinfection for both residential and commercial use.
