Specific features

Air flows normally within AHU in countercurrent (direct current is also possible)

Recommended for applications with low flow rates

Supply and extract air stay on the same level throughout the AHU

Bypass

• Recovered energy can be controlled through a bypass
• The bypass valves must be equipped with a modulating actuator
• The fresh air can be bypassed (freecooling and frost protection). For ECOTWIN the extract air is also bypassed (energy savings).
• The fresh air bypass is necessary for applications with extract air with a relative humidity of >45%, low outdoor temperatures and at high efficiencies

Features

• Long service life & easy and flexible in use
• No humidity recovery
• Direct heat exchange without intermediate medium
• Static exchanger, no moving parts (except for the bypass valves)
• If there is no demand for heat recovery and in freecooling mode, the air side pressure drop across the recuperator and along the supply and extraction side almost equals 0 (energy savings)
• Category I according to EN308
