Double wall insert HSI Varia 05.09.03

The HSI 150 VARIA modular grommet is an innovating system allowing easy passage of cables and pipes in concrete constructions. Modular grommets will be studied as early as the worksite preparation, so that they can be planned and positioned during concreting. They are delivered per part or assembled in matrices, suited to the wall thickness.

The HSI 150 VARIA has an interior diameter of 150 mm .

The VARIA system adapts to the shell thickness encountered on the worksite.

Benefits

Double safety thanks to the closing covers and protection
Pressure sealing with respect to concrete by seal with 3 injected grooves
Quality label: factory tested for watertightness. Possibility of checking in case of untimely or unauthorised opening of the closing cover
Water and gas tight up to 2.5 bar
Possibility of connection on either side for watertight system (e.g. connection for grommet sheath and cable tightness)
With its nestable system, double flange HSIs can be battery-mounted on-site
Adjustable on-site to the shell thickness

LEVIAT technical advice

Many combinations are possible with the HSI systems. By reporting your specific case to our sales engineer, who will be able to advise you on your project.

+ Accessories

1. Jointed wrench for opening the plug cover and tightening the closing cover

2. Covers

Please refer to the Covers section

3. Spacers

When connecting large cross-section pipes (diameter 160 or the KES system), always use the spacers between the HSI elements to allow subsequent fitting of accessories.

4. HSI 150-DG

The HSI 150-DG system is composed of an HRK watertightness ring as well as an adaptation ring. It is not possible to place an HRK watertightness ring without the adaptation ring as the diameters do not match. The complete HSI 150-DG system can be ordered, but if you already have HRK rings, it is also possible to supply adaptation rings separately.

+ Covers

1. Multihole cover for cable passage

Different covers are available according to the HSI passage diameter used (HSI 90 or HSI 150).

All covers are available with watertight sleeves, which are hot retractable (standard) or cold retractable.

For HSI 150, there are 3 covers for 1, 3 or 7 passages respectively, diameters 25-78 mm, 22-56 mm or 12-31 mm

2. Plug

When all passages in the cover are not used, the holes can be closed with plugs

3. Centring strip

The centring strip allows the user to centre the cable in the passage while avoiding damage to the cable, and optimising the watertightness of the heat-shrinking or cold-shrinking sleeve.
