The Enervent LTR-3 unit is best suited for terraced houses and smallish detached houses. 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.
