    The MVHR unit casing is assembled from a self-supporting frameless construction, manufactured with double skinned, corrosion resistant, 50mm deep hot dip galvanised sandwich panels (0.8mm gauge).

    The outstanding mechanical strength, thermal and acoustic performance of the casing is assured by packing the panels with high density rockwool (88kg/m³) with excellent thermal and acoustic performance (D=0.041 W/m.K, fire resistance class A1 to 13501-1 + A1: 2009 - non-combustible).

    The panels are joined with internally enclosed self-screwing fixings which creates a smooth, crevice-free, interior surfaces which are easy to clean.

    The panels are finished with a powder paint finish for optimum corrosion protection.
    To avoid external air leakage both fixed and access panels are sealed with an high tightness, EPDM closed cell gasket.


    The HR95 MVHR unit is suitable for free standing internal or external installation as standard.
    The units can be configured as vertical (double-deck) or horizontal (side-by-side) with the exception of sizes 450 and 550 which are available in vertical configuration only.

    All units are supplied as a single piece package.

    Access & Maintenance

    Access to all the unit compartments is available through the tool operated access panels as standard. Top access panels on the units are supported by hydraulic support strut.

    All access panels are equipped with handles to facilitate handling during maintenance operations.
    The control panel is installed in an easily accessible, enclosure inside of the unit.

    The vertical units control panel is enclosed on the top of the unit, the horizontal units control panel is enclosed on the side of the unit.
