Technology that satisfies all standards

First-rate ROMOLD quality

100% VIRGIN MATERIAL

Only virgin material ensures lasting quality, welding capability and thereby absolute tightness Only our 100 % knowledge of the material alows definite statements on the durability of our products and welds.

PRODUCT RANGE

Over 160 different, industrially produced chamber bases (from DN/OD 160 to DN/OD 630) are available within a very brief time.
Connections are possible from 90° to 270° and are suitable for nearly all materials. Additional, custom connections are also no problem.

INSTALLED UPLIFT RETENTION

ROMOLD chambers all have integrated uplift prevention thanks to their external ribs. These ribs mesh with the backfilling material. No additional constructional measures are necessary. The chamber base is sufficiently secure against deformation, therefore lining with concrete is unnecessary.
Please note assembly and installation instructions. Backfilling of the chamber construction must be done using materials of type ATV-DVWK-A 127 (group 1 and group 2 of table 1) or in accordance with DIN 1055 part 2 (non-cohesive soils - see table 1). Backfilling and compacting of the chamber construction  must be carried out in accordance with EN 1610 and DWA-A 139. According to static calculations, a ROMOLD chamber of DN 1000 (height 5.0 m, groundwater up to top ground surface) has a safety factor of 2.3 against uplift by groundwater.

INSTALLATION SITES

ROMOLD chambers can be deployed from class A 15 / group 1, to class E 600 / group 5, in accordance with EN 124. Tested in accordance with EN 14802 and deployed in Europe‘s streets for over 20 years.

CHAMBER ELEMENT SEAL

EN 681-1 and EN 1277: watertight to 0.5 bar. ROMOLD element seals (Triple-Safety-Seal) meets the material requirements specified for EN 681-1 (EPDM material) and is available for all chamber diameters. ROMOLD element seals are 3-sided lip seals, which can easily be installed (manually without force). Increasing internal or external pressure increases the effectiveness of the seal. The labyrinth lip seal on both sides provides twice the safety of single -sided seal systems

CHAMBER CONES

EN 476: Minimum access opening DN 600 required for accessible chamber systems. ROMOLD chambers have a DN 625 access opening.

INSTALLATION HEIGHT ADJUSTMENT

As opposed to the traditional construction, the height of ROMOLD plastic chambers is adjusted by shortening the upper component. On the outside, at intervals of 1 cm marking rings / small ribs permit precise level cuts. Chambers / cones can be shortened using a saw suitable for woodwork, e.g. a handsaw or jigsaw. DN 1000 and DN 800 chambers can be shortened by up to 250 mm, DN 625 and DN 500 chambers by up to 300 mm. All chambers are available in overall heights that differ by the shortening amount. This allows all overall heights to be created precisely and to the nearest centimetre.

CLIMBING STEPS

EN 13101 and/or EN 14396:
Corrosion-free climbing steps are factory fitted for ROMOLD DN 800 and DN 1000 accessible chambers. The strength fulfills standard requirements. The climbing steps are 250 mm apart.


ATV-DVWK-A 157:
The bottom climbing step is from ≥ 250 mm to ≤ 500 mm from the berm.
Safety is increased by a textured surface. If necessary, the climbing steps can be removed.

ACCESS AIDS

ROMOLD chambers can be fitted with access aids. Access aids can also be retro-fitted to installed chambers.

RINGS

Overall heights of DN 1000 rings  are 25, 50, 75 and 100 cm. Overall heights for DN 800 are 50 cm and 100 cm, for DN 625 and DN 500 they are 10–40 cm, 30–60 cm, 60–90 cm.

BERM

DIN V 4034-1 / ATV-DVWK-A 157:
Angle of step surface ≤ 1:20. The berm is anti-slip.

CHANNEL

DIN V 4034-1 and/or ATV-DVWK-A 157:
Channel height 1/1 D (for channels up to ND 400)

GRADIENT

The gradient is at least 0.5%.
