The Enervent LTR-7 XL unit is best suited for large detached houses and public spaces, such as schools and kinder gardens.

The LTR-series units are designed for installation in the roof, in the attic, in a false ceiling or in a technical space. The horizontal installation often saves a lot of space. LTR-series units are well insulated and can be installed in cold places. The unit needs additional insulation if the temperature around it drops below -10°C.

The simple but ingenious structure and the low pressure drop of the unit ensure an inexpensive and safe operation.

Enervent LTR-7 XL are‘non-residential ventilation units’ (NRVU) according to the EU Commission Regulation No 1253/2014. Ventilation units with maximum flow rate over 250 m3/h which the manufacturer has not declared intended as being exclusively for a residential ventilation application are called non-residential. Non-residential ventilation units (NRVUs) are excluded from EcoDesign labelling.

Our calculation software Energy Optimizer, reports whether the chosen NRVU unit fulfills the EcoDesign requirements or not for the intended project.

Duct connections

The LTR-7 XL is available only with a right-handed duct connection layout.
