Active recovery Circuit dedicated to recovery, with independent control, adapted to the air refreshing requirements in order to raise the COP and EER of the unit set. • Centrifugal fan in top box MRC1 or electronic lower plug-fan MRC0. • Air circuit comprised of coils with copper pipes and aluminium fins. • Thermostatic expansion valve with external equalisation. • Hermetic scroll-type compressor with sound insulation, assembled over antivibration mounts. • Crankcase heater. • Four-way cycle reversing valve (heat pump units). • Anti-acid dehydrator filter. • Condensates drain pan.
Comfort / indoor air quality options Gravimetric filter G4. Gravimetric filter G4 of low pressure drop. Opacimetric folded filters F6 to F9 + gravimetric G4. Opacimetric folded filters F7 and F9 of low pressure drop + G4 of low pressure drop. Double stage creased opacimetric filters (F+F standard or F+F of low pressure drop). With this option, a technical consultation must be made due to changes in unit dimensions (with MS assembly and top or bottom return).
Air quality probe for installation in the environment to enable measuring CO2 and/or volatile compounds. Supply and/or return fan with high available pressure. Control of the overpressure with the MC0 and MC1 assemblies. Condensates drain pan for the outdoor circuit in galvanised steel (consult dimensions drawing). This option is not available when maritime transport by container is required. Outdoor coil protection grille. Outdoor coil antihail grille. Compression latches of quarter-turn in filters and / or fans access panels. Hinges + compression latches of quarter-turn in filters and / or fans access panels. Standardised pre-assembly frames made of galvanised steel panelling, thermally insulated. Adjustable height. Adaptation frames for replacing units on site.

Installation options -
Passive recovery Rotating heat exchanger in a module attached to the machine, with electronic plug-fans for supply and/or return (MWC1 assembly). Available for models 415 to 960. This wheel recovery allows to transfer heat and humidity of the return air from the conditioned premises to the take in air, before to expel it outdoor. This support for free-cooling reduces the operating time of the machine, with the consequent energy saving and benefit to the environment.
Antivibration mounts made of rubber
