Electric air heaters

The air heaters with integrated electrical heating elements, flange frame or fixing plate as well as casing for electrical connections are laid out and assembled according to the customer's specifications and operating manual.

A higher thermal efficiency is attained using a specific surface load (pa), which is optimally adjusted to the operating conditions.

Materials are made of steel or stainless steel according to customer's instructions.

The temperature monitoring for protecting the heater and maintaining of the temperature classification is achieved using temperature sensors, which are located on the heating elements and electromechanical or electronic switches or monitoring devices. Usually flow monitoring is required for safe operation.
