Fujitsu introduces ductless split systems that offer up to 33 SEER to operate with optimal efficiency at ambient temperatures of -15° F. The new 9,000, 12,000 and 15,000 Btu inverter systems are available with these capabilities off the shelf with no modifications needed for low ambient operation. Fujitsu’s Extra Low Temp Heating (XLTH) models feature a built-in base heater and drainage holes so condensation doesn’t freeze and can drain out when ambient temperatures are low. All RLS3H inverter wall-mount systems are available as split-system heat pumps and offer super-quiet operation and nearly full heating capacity down to -15° F ambient and cooling operation down to 14°. Refrigerant pipe lengths can reach 66’ between the evaporator coil and the condensing unit.
