Hydronic fan coil units for fast heating and chilled-water cooling — wall, bulkhead, cassette and concealed ducted models. AHHAC supplies the MAXA Grimper, HCN, HCNP, HCNA and VE fan coil ranges.
Fan coils are the workhorse emitter for hydronic cooling and fast-response heating. A fan blows room air across a finned hydronic coil — warming it from the boiler/heat pump in winter, or cooling and dehumidifying it from chilled water in summer. Where underfloor is silent and slow, fan coils are fast and powerful, making them ideal for cooling-led climates and rooms that need quick warm-up.
AHHAC supplies the full MAXA hydronic fan coil range: the Grimper Anviro series, the HCN / HCNP / HCNA cassette and bulkhead units, the VE residential and inverter range (VMI, VMF, OMP, OMI / VII, VIF, OIP, OII), and concealed hydronic wall units. Each pairs with the MAXA Airmust and CRA thermostat range for precise control.
Wall-mounted (high or low) — the simplest retrofit, like a split-system head but hydronic. Bulkhead / under-ceiling (HCNA) — concealed above a doorway or in a service zone. Ducted cassette (HCN, HCNP) — fully concealed in the ceiling with grille outlets, the premium invisible option. Concealed floor units — for under-window placement. AHHAC sizes each unit to the room's heating and cooling load and specifies the matching MAXA thermostat.
