Congratulations
You have chosen a product from Helios Ventilation Systems. This means that you have purchased a premium product and you will benefit from our
many years of experience. All KWL EC 220/340 D R/L units have been tested at every stage of production. Not only has the obvious function (e.g. the
fans running) been tested, but also the functions which you, as the customer, cannot test. For example, these include internal and external leakages and
electrical safety. We enable you to reduce operating costs through innovative ideas in the field of control and feedback control systems. We achieve this
through intelligent frost protection strategies, which only become active if the performance of the heat exchanger is affected.
However, if you unexpectedly have a problem with our unit, you can contact the specialist installer or our Helios customer service team.
