Xpelair Ventilation’s Xcell Stratum low-profile heat-recovery unit is available in four models with heights from 170 to 350 mm to suit a variety of applications and ventilation needs in new builds and refurbishments. Made from B1-rated EPP structural material, these units are considerably lighter than those with metal cases. The high U-value means there is no cold bridging.
Key features include long-life ultra-efficient EC motors and 88 to 90% heat recovery. Other features include integrated programmable, multi-speed control units, frost protection and 100% summer bypass on some models. There are integral fixing points.
The F5 G4 filters can be changed without tools.
