Air heaters / duct heaters

Electric Volta air heaters are used for the efficient direct heating of flowing air and gaseous media. The electrical energy introduced is transferred almost without loss to thermal energy and passed on to the process.

Thanks to its full vertical range of manufacture and extensive process know-how, Volta is able to optimally take all requirements into account and implement them with a short delivery time. The entire air heater range is covered with outputs from 0.5 kW to over 1 MW and from laboratory applications to power plants.

A modular system, a wide variety of designs and possible combinations allow either model series and series to be defined inexpensively and individually, depending on requirements, or a design that is optimized for each project and order. Whether duct installation, pipe installation or device installation, we can optimally cover your wishes for your electric heating register.

The equipment, material and accessories can also be combined in different ways to ideally cover the respective application.

The Volta heating elements of the heating register are also extremely versatile in their specification and possible application. Their large-scale, resistant and fiber-free design makes them extremely durable, environmentally friendly and ideal for use in both low and high temperatures.
