HiLTO EC heat recovery unit

The HiLTO EC is an energy-efficient, high-performance heat recovery unit. With the HiLTO EC, more than half of the thermal energy in exhaust air can be recovered and used to reduce the heating costs of a property.

Excellent for both new and renovated buildings, the energy-saving HiLTO EC transfers heat from exhaust air for use in heating supply air, warm water or heating system water.

Core components of the heat recovery unit are finned coils, operating with heat transfer fluid combined with the HiFEK EC technology. The motor utilises the permanent magnet technology combined with an integrated frequency converter. Manholes on both sides of the HiLTO EC make the unit easy to install and maintain. Filters and the finned coils equipped with condensation water basins have been installed in a vertical position. The hinged fan can easily be moved to the maintenance position.
