Our subsidiary SND PorzellanManufaktur in Zeulenroda refines mugs and porcelainware with passion. The energy required for kilns and finishing processes is to be generated and used as efficiently as possible. As part of JCK Holding, SND makes targeted investments in modern energy and utilities technology. These investments increase efficiency while reducing the amount of energy purchased from external sources.
On site solar power with battery storage
Since early 2024, SND has covered around 30% of its electricity needs with power generated by its company owned photovoltaic system. With 78 kWp of installed peak capacity, solar power is generated directly on site. A 44 kWh battery ensures surplus energy is available even when the sun isn’t shining. With a self-consumption rate of over 70%, a large share of the electricity generated is used directly on site, reducing the amount of electricity drawn from the public grid.
The next step is already planned: an expansion to just under 100 kWp of PV capacity and a larger storage unit. By staying below this threshold, SND deliberately avoids the statutory direct marketing requirement, allowing the electricity generated to be used primarily on site and enabling the team to keep its focus on the core business.
Efficient compressed air supply
Compressed air is essential to many of SND’s production steps. To achieve an efficient supply, SND has equipped its compressed air center with state of the art KAESER technology: two stationary rotary screw compressors (SM 10) and a variable speed compressor (SK 22 / 8 SFC) provide dry, oil free air precisely as needed. Their interaction is coordinated by the SIGMA AIR MANAGER 4.0, which continuously monitors pressure, flow and energy use across all components. By automatically prioritizing the most efficient units, energy consumption and downtime can be reduced.
A key advantage: the setup is fully redundant. If one compressor requires maintenance or fails, the remaining two seamlessly take over—without production interruption and without costly express repairs or rental equipment. The result is high availability and planning reliability.
With these two flagship projects, SND demonstrates how modern technology and disciplined energy management go hand in hand. JCK Holding is proud of the innovative strength of its subsidiary: On-site solar power generation and demand-based compressed air control help SND reduce its reliance on externally sourced energy and use energy efficiently. At SND PorzellanManufaktur, craftsmanship meets forward looking engineering.
