Extraneous Water Sealing System for street manholes (inspection shafts) protects against surface water entering through the ventilation openings of the manhole cover.The Extraneous Water Sealing System is proven to be effective especially with these advantages: It has an aeration and deaeration function, is low-maintenance and convenient due to automatic closing and opening. All materials used are suitable for permanent use in sewer systems.Application areas of the Extraneous Water Sealing SystemSuitable for manhole openings with a diameter of 625 mm +- 5 mmApplicable for overflow heights up to 0.5 m above street levelDesigned for manholes according to DIN 4034 and manhole covers according to DIN 19584 (standard BeGu frame), special mounting supports available on requestAdvantages of the Extraneous Water Sealing SystemReliable sealing of manholes in case of surface water inflowFull aeration according to DIN EN 124 after surface water inflow ceases
Low maintenance due to large sediment collection space
Suitable for overflow heights up to 0.5 m

Prevention of biogenic corrosion in sewer systems with aeration and deaeration function
Eliminate odor from manholes and protect your manhole structures from corrosion with our odor control system FVA-4 DN1000.
As an alternative to conventional filters deployed at the top of the manhole, this system is installed above the berm. Gaseous pollutants from the sewer system such as hydrogen sulfide (H2S) are therefore retained, preventing odor and sulfuric acid corrosion above the installation level.
Application areas of FVA-4Designed for municipal and industrial wastewater systemsSuitable for manholes with an inner diameter of 1000 mm +- 5 mm and an entrance opening of min. 600 mmThe minimum depth of manhole shafts should be 1.2 mOur odor control systems are designed for manholes according to DIN 4034 and manhole covers according to DIN 19584 (standard BeGu frame), special mounting supports available on request
Get rid of odor complaints from citizens with the Uni-AdSorber! Satisfied sewer system operators choose our Uni-AdSorber DN625 manhole odor cushioning system to efficiently eliminate malodors from sewer shafts. As an alternative to conventional biofilters or activated carbon filters, the Odor Cushioning Systems from UNITECHNICS do not require replacement of the filter material. The filter material rinses itself through rainwater flowing into the shafts or condensed water vapor in the filter. Thus, the filter material is only decomposed by UV light and does not need to be changed. For an additional decomposition of odorous substances, microorganisms are settled in the filter material, which activate the essential biochemical processes.Our manhole odor filter is designed for application in municipal and industrial wastewater systems. Manholes according to DIN 4034 and manhole covers according to DIN 19584 (standard BeGu-frame), special mounting supports available on request.Basic variant - for medium H2S-loads.HD variant - for extreme H2S-loads. HD stands for Heavy Duty - the high-performance version.Please note: special dimensions and special applications (e.g. for aggressive media in industry) are available on request.We have the matching odor filter for every challenge!Application areas of the UNITECHNICS manhole filterManhole filters for municipal and industrial wastewater systems.Our manhole filters are designed for manholes according to DIN 4034 and manhole covers according to DIN 19584 (standard BeGu frame), special mounting supports available on request.The Uni-AdSorber-B (B for Basic, the basic model) manhole filter is designed for predominantly medium H2S loads.The Uni-AdSorber-HD (HD for Heavy Duty, the high performance version) manhole filter for extreme H2S loads.

Having complaints about odor in the sewer? We have the effective solution for you: Odor Sealing System GVS-450-150 for effective prevention of odors from street drains. Fast installation and dismantling is possible with the comfortable handle. The odor sealing flap ensures unobstructed rainwater runoff. Installation position is below the dirt collector. As no consumable material is required, maintenance costs are minimal and no other subsequent costs are incurred.Application areas of GVS-450-150Designed for permanent use in both municipal and industrial wastewater systemsSuitable for street drains according to DIN 4052 (diameter 450 mm)Special dimensions are available on request
Fight against rats and other pest rodents efficiently and in compliance with the regulations with the Rat Ball.The problem is familiar to many sewer system operators: rats and other pest rodents that live on the surface and in sewer systems carry and spread diseases. In cooperation with pest controllers and sewer system operators, we developed a target-oriented solution: The Rat Ball.The small handy ball is approximately the size of a soccer ball. It reliably protects the bait from water. It can be replaced quickly, but will not be washed away by inflowing water. Installation does not require entry into the manhole. Completely without damage (no drilling required), the ball is attached to the dirt collector with a rope.We also offer the Rat Balls in a practical pest control set with transport box. Your advantage: Practical handling for transport, cleaning and storage of the Rat Balls.Application areas of the Rat BallManhole structures with an opening of Ø 300 mm or larger.Advantages of the Rat BallSmall and handy in size (like a soccer ball)
No flushing away of the bait possible
No entry into the manhole for installation
Damage-free installation (no drilling), fastening by rope to the dirt collector
Quick bait change
Easy relocation to another manhole
Reliable protection against backflow through elevator principle (see animation)
Reliable protection of the bait from inflowing water from above
The UNITECHNICS Rat Ball is an effective pest controller for sewer system operators
The Rat Ball is also available as a rat control set (the rat control set consists of 5 Rat Balls and a transport and cleaning box)The rats love it!NoticeThe Rat Ball meets the current legal requirements of the Biocide Ordinance for sewer baiting. Please find more information in the "Downloads" tab.
