LIPP® Thermal Storage Tanks

For the intermediate storage of renewable energies – from 200 to 2,000 m³

The LIPP thermal storage tank is the tailored thermal storage solution for renewable energies with an effective volume ranging from 200 to 2,000 m3 which is suitable for individual customisation.

Expedient thermal storage is a prerequisite for the effective utilisation of heat from biogas plants, biomass cogeneration plants, solar plants or other heat sources. The flexible-capacity LIPP buffer storage tank provides the ideal solution for this application. The tanks are fabricated on site using the tried and tested LIPP Double-Seam System and the stainless steel VERINOX®.

Insulation can be tailored to the intended application in order to produce large-volume, above-ground storage tanks with an individually customised interior. The tanks are designed for non-pressurised operation with an operating temperature of up to 95 °C and are suitable for use with heating water. No additional nitrogen system necessary.
