Jenni Energietechnik Inc. products

Most of our tanks are constructed for the use as part of a thermal solar energy installation. All across Europe, we are known for the  Swiss Solartanks. The way we install solar plants for heaters and hot water has become a worldwide standard.

The tank is the central element of any solar energy system. The performance of the entire system depends largely on the tank and its management.

The heat exchanger is designed to deliver the heat from the solar circuit (which is filled with a mixture of water and antifreeze) to the tank water. It is important that this happens with as little loss as possible (AT max. 5-10°C). For this purpose the integrated flat tube heat exchangers in the tank have proved to be the best solution. Devices and machines specially designed by us allow the efficient production of heat exchangers.

Storing heat means insulating heat. The insulation (130 - 300 mm) can be delivered separately for the self-installation or be installed by our employees in place. Especially large tanks are increasingly being insulated in the factory and delivered along with a weather-protective film.

optional with integrated heating control. For a simplified and safe process, we offer armature groups (solar, heating, ventilation etc.) separate as well as pre-mounted on our tanks. The mounted and wired control system completes the energy centre. Complete offers from one source are less expensive. In addition, our armatures are serviceable and extremely longlasting due to the omission of pre-formed parts.
