• Permanent sound, pitch fixed • optionally with switchable interval- / permanent sound • Devices available in 2 enclosure versions: - I- and-version, e.g. IK _ _ _ _ with depth 61 mm, with terminals at the bottom for installation systems and industrial distribution systems according to DIN 43 880 - S-version, e.g. SK _ _ _ _ with depth 100 mm, with terminals at the top for cabinets with mounting plate and cable duct • Width: 17,5 mm

Optigrun Pitched Roof Board FKD 58SD is used for pitched roofs with a pitch in between 15° and 35°. Made from expanded polystyrene. With precisely fitting Z-fold on top and bottom edge and lateral indentations for safe shear stress transfer in direction of the water flow; no possibility of substrate reaching the protective layer thanks to tight fit of horizontal and lateral edges. The integrated chambers provide excellent anti-slippage for the substrate, high water storage capacity and an integrated water distribution system. Lay out according to manufacturer informations with max. 80 mm overfill (incl. vegetation mat).

The stable structure of Betonbau modular units enables factory equipping with plant and equipment. Factory installation is particularly economical, considerably reducing your co-ordination outlay for many minor tasks on the construction site. On-site commissioning time is considerably reduced as a result. The spectrum in this respect ranges from the basic 230V/400V installation for lighting, heating and socket circuits to the integration of emergency lighting and explosion protection. We can supply a standardised sub-distribution system with the delivery if requested, meaning you simply have to connect everything on site. Cable trays, electrical heating equipment, ventilators, air conditioning systems and sanitary equipment can be fitted in the manufacturer's facilities if required. Experienced engineers and master craftsmen plan and monitor the production and, together with our installation technicians, ensure that quality and safety standards are reliably realised.

Large heat and flow meters are often used continuously for decades after an initial calibration at external test benches. A recalibration of these meters within their actual operation conditions was not possible so far. In the best case scenario those flow meters are unmounted and recalibrated on an external test bench. Drawback of this method is an interruption of supply in addition to its already high costs. Furthermore, calibration conditions can differ greatly from actual operation conditions compared to test bench conditions, so even if calibrated, the measurement uncertainty in operation remains fairly unknown. This often leads to more difficult fluid distribution optimizations and leaves billing fairness to a gamble. More precisely measured values of flow sensors may uncover hidden saving potentials within the fluid distribution system and allow more exact performance indicators, improving energy efficiency.
