Installation and Service


The Anhamm barrier is delivered in one single unit and is positioned in the ground pit. After the barrier is adjusted to the correct position, the piers of the unit are bolted to the wall on either side. Next, mortar is poured into the recess beneath and surround the unit. The Anhamm design does not not need any external power supply or any other external connection. No switchgear cabinets or similar installations are needed.

Maintenance-Free Simplicity

The key to Anhamm Spillbarriers are their simplicity! Customers world-wide love the easy-to-use, easy-to-test reliability. All mechanical parts are maintenance-free and only require simple cleaning around the barrier gate. And the barrier, regardless of size, can easily be tested manually.


We do all the service that is needed to make the anhamm spillbarrier.


Activation of the spill barrier without external energy

Automatic activation of the barrier through incoming liquids.No external energy sources are required: no electrics, no pneumatics, no hydraulics.No sensors and no connection to sprinkler or fire alarm systems necessary.

High-quality material guarantees durability

Standard use of 1.4301 (AISI 304) stainless steel.The PTFE coating makes the gasket highly resistant to chemicals and aging.ATEX protection possible without additional costs, since no electrics are used.

Manufacturing and Installation

The Anhamm safety spill barrier is delivered as a complete assembly unit. It is individually manufactured to the respective planning case – whether for new buildings or refurbishments.Floor-level installation – therefore easy to drive over with forklift, trucks, etc. No ramps and sleepers guarantee unhindered factory traffic.Due to the sandwich construction highly loadable (3.25 tons wheel load tested by TÜV Nord according to DIN 1055).

No operating costs - low maintenance costs

The spill barrier is triggered purely mechanically. Provided proper maintenance is carried out, the Anhamm fire-fighting water and chemical retention system does not incur any operating costs.Maintenance work and costs mainly consist of cleaning and a manual function test.The mechanical function simplifies the repair on site.

Can be used for the retention of hazardous substances

The Anhamm spill barrier has already been approved several times by the authorities as hazardous substance retention.
