An increasing variety of buildings and industries employ VEAB duct heaters for the primary heating of fresh air supply in HVAC systems, for supplementary heating to individual zones and rooms, and for heating air supplies in industrial processes.
They can be supplied with thermostats and temperature controls as well as “run on timers” for fan control.
VEAB – Rectangular Duct Heaters
Rectangular duct heaters are available in ratings up to 2000 kW and are used for heating the supply air in duct systems, central ventilation units and for industrial processes. If correctly rated, rectangular duct heaters can provide heating for entire houses and buildings. Our flexible production system enables us to adapt the duct heaters accurately to the application. This may be heaters for air handling units, industrial processes or very arduous environments. This may involve the need for strengthened electrical insulation, the use of stainless steel, high power ratings, high operating temperatures or the like.
VEAB – Circular Duct Heaters
Circular electric duct heaters are used for heating the ventilation air supplied to rooms and zones with individually controlled temperatures. In correctly designed systems, they can also heat the entire building. Circular electric duct heaters are also used for reheating the supply air in ventilation units with heat recovery. The duct heaters are available with built-in electronic regulator or for external control. All stocked heaters have an electronic flow monitor as standard.
