We're in big business
Appliances and vessels leaving our workshops often attract all eyes. They weigh tons and are many meters long, so they demand everything from our employees. Highly complex engineering services, top quality and technical perfection in production as well as solution-oriented thinking are among the skills and abilities that our employees in apparatus and tank construction use every day.
Apparatus and tank construction
High-pressure apparatuses of carbon steel alloy. Pressure vessels made of CrNi steels for corrosive processes. Welding constructions weighing tonnes for very high loads. All this with unexampled precision, made possible by one of the most modern machine parks in Europe. Spatially strictly separated, we work the very latest materials from plant construction. For CrNi and Nibas steels, one of the biggest pickling plants in Austria takes care of the perfect finish. The high quality is assured by our certifications and the in-house NDT department with state-of-the-art testing equipment.
Perfect support and complete solutions for your process. Our engineering seamlessly joins the basic engineering of the process provider and the customer. Consultancy, development, analytical and FE stress calculations, heat technology designs, detail engineering and welding technology are carried out directly by our technology sections.

Apparatus and tank construction
Heat and electricity are generated according to the principle of combined heat and power. A heat accumulator allows the de-coupling over time of the heat and electricity production, in that the “excessive” production of heat energy is temporarily stored practically without any loss over several days. The heat accumulator thus optimises the operation of a power plant and allows flexibility in the changing conditions of the power market.
- Pressure-less heat accumulators: up to V=50,000m³
- Pressurised heat storage units: factory-manufactured up to ø4.4m
- Pressurised heat storage units: manufactured at the site from ø4.45m
- Conceptualisation of the required tank size
- Design, from a process engineering perspective, of the tank parameters like the nominal width of the inlet and outlet, the size of the water distribution diffusers, the splash water system for roof space inertisation, the safety devices for securing against overpressure and underpressure or against overfilling.
- Detail engineering for heat accumulators, operating steel construction and integration piping
- Detail engineering for the insulation, including the heat loss calculation in accordance with the Cogeneration Act (max. permissible heat loss = 15 W/m²)
- I&C detail engineering like planning, manufacturing and supply of the switch cabinets or the PLC programming
- Prefabrication
- Delivery
- Installation of heat accumulators and operating steel construction
- Installation and wiring of the I&C components
- Insulation

Apparatus and tank construction
Process engineering processes, such as thin film evaporation, are complex procedures that require an exact design – from feasibility studies, process engineering considerations, engineering outputs, laboratory and pilot tests and their implementation and installation, up to commissioning and maintenance. For the process industry, too, Kremsmueller supplies concepts that cover the entire life cycle of a plant.
