ECOROT Rotation Heat Exchanger

Principle and Operation

This energy recovery system consists of a slowly rotating wheel (max. 5-20 rpm), made of thin undulated aluminum plates, that accumulates the heat and/or humidity from the extract air and transfers it to the fresh air.

Features and Focal Points

Not suitable for hygienic applications or potentially contaminated exhaust air systems since the extract and supply air can get mixed in a very small degree (<1%) by use of the same exchange surface
Self-cleaning effect by countercurrent principle with rinsing zone if supply and extraction fans are installed at the suction side with respect to the wheel
High heat and humidity recovery depending on the selected rotor
Simple power control by speed control
Duo Ecorot arrangement is also possible
Easily meets the Erp Eco Design Directives of 2016-2017 and 2018
3 types of wheels are available based on the recuperation requirements:

Rotor (according to EN308)	Recuperation	Hygroscopic
Condensation (cat. IIIa)	Heat and humidity (only with condensation)	No
Enthalpy (cat. IIIb)	Heat and humidity	Yes
Absorption (cat. IIIb)	Heat and especially humidity	Yes
