Two neoTower 25.0

For the new hall, two neoTower® 25.0 cogeneration units have been selected as a particularly efficient option in terms of both electricity and heat, as the two units provide between 12.5 kW (individually) and 50 kW (combined) of electricity and between 34.8 kW and 109.8 kW of heat in a continuously modulating manner. Krauss Haustechnik GmbH from Klein Offenseth-Sparrieshoop was responsible for the installation. neoTower® cogeneration units are characterised by the robustness of their Yanmar gas engines, which can run on either natural gas or biomethane and are already approved for hydrogen blends of up to 40 per cent. One reason for this longevity is the impressive 3.3 litre displacement. Combined with a low engine speed of 1,530 rpm and a 90-litre engine oil capacity, the result is a long maintenance cycle of 8,000 hours. Ongoing remote maintenance, remote monitoring, remote evaluation and remote reporting also ensure long-term worry-free operation. This can be rounded off with one of the various maintenance contract models offered by RMB/ENERGIE.


The ever-expanding company Oxytabs, a manufacturer of descaling and cleaning products for households and agriculture based near Rendsburg, relied on the dual power of two 25 kW el neoTower® combined heat and power units for the basic supply of heat and electricity in its new hall. Power. A centralised power and heat supply is important for the operator to secure its own energy supply.
