New and imaginative ideas with design diffusers – Explore your creativity

We conduct all types of air-conditioning; from ventilation of industrial facilities, business premises, residential facilities, to cleanrooms. Ventilation is the supply of fresh, less humid and clean air into the area, thereby replacing spent, unclean and damp air. Ventilation is absolutely necessary, as staying in poorly ventilated facilities is harmful to our health

As a leading manufacturer of floor convectors reliability, availability and efficiency have top priority in the field of floor convector operation.

Floor convectors can be used either as a highly effective primary heating system or as a secondary heating system to help increase overall heating system efficiency.


Displacement Technology? – Effiecient and Economical

What exactly is air treatment? Nowadays stricter requirements are imposed on the air climate in commercial buildings. After all, it is important that a healthy work climate prevails. This is not only a requirement, it also significantly increases the productivity of employees. An air handling unit or air treatment installation ensures that the air in a building is always of good quality. Gerhman Displacement Technology is the market leader in this field and is happy to help you with clean air and a healthy working climate.

Introduction to design engineering

It is important to note that all Gerhman displacement ventilation diffusers are supplied with adjustable air pattern controllers. The ability to adjust the shape of the air pattern and the resultant adjacent zone can be of great benefit when dealing with furniture, occupants and obstructions.
