Napoleon® 25 SEER Ductless Inverter Heat Pump Mini-Splits – Single Zone

[tabby title=”Description”]
Stay comfortable year round with these single zone high efficiency ductless heat pump mini-split systems with energy saving inverter technology. Based on the heating and cooling needs of the space, the compressor adapts to produce consistent comfortable temperatures while saving energy year-round. This is a great option as either an alternative to a ducted system, or if adding duct work is not possible. One of the most common needs for a ductless system is in retrofitted additions to houses, loft and office spaces, and are also ideal for newly enclosed spaces such as decks and garages. They are also popular for zone cooling in a particularly sunny room, or a theater or computer room where electrical equipment may heat up the space. Hamilton is offering Napoleon’s line of inverter heat pump mini-split systems which are available up to 25 SEER. The system is designed for residential and commercial applications and consists of the outdoor condenser, indoor head unit, remote control, and 25 ft. insulated line set. The condenser is charged with R-410A refrigerant and has a side air discharge. The system is AHRI Certified, and ETL Listed in Canada and U.S. Final connections from line set to coil and condenser must be done by a certified technician.

[tabby title=”Features”]

Up to 25 SEER (Seasonal Energy Efficiency Ratio) ensures optimum comfort without intensifying utility bills

9,000 to 36,000 BTU models of heating and cooling capacity

EER (Energy Efficiency Ratio) range from 8.6 to 14.5 in the NH25 series

Environmentally friendly R-410A Chlorine-free refrigerant

Refrigerant Leak Detector

WHISPER QUIET™ operation with an indoor sound rating as low as 25 dB and the outdoor unit as low as 55 dB. See the brochure for noise levels of each model

Easy to use remote control thermostat, controls all functions of the indoor unit

Air filtration, filter helps clean volatile organic compounds (VOC’s) and harmful gasses and odors and consistently provides healthy air

Auto restart, if the air conditioner turns off unexpectedly due to power failure, it will restart with the previous function setting automatically, once power is restored

Sleep mode, Maintain energy savings and comfort in night operation. Automatically increases cooling or decreases heating 1.8°F/(1°C) per hour for the first two hours and then maintains temperature for the next five hours until it shuts off

Auto swing, distributes air to the farthest reaches of your home by automatically moving the blades

Easy clean panel, front panel of indoor unit is detachable for easy cleaning

DC inverter, high efficiency for lower fuel bills. Superior operation drastically reduces noise

LED display, the flat panel LED display window illuminates the temperature for easy reading; select either Celsius or Fahrenheit

Hyper Heat feature; functions in temperatures as low as -22°F/-30°C (NH25-09F, NH25-12F, NH25-18F, and NH25-24F models only)

NH25-30F and NH25-36F Models function in temperatures as low as 5°F/-15°C

Different from the cooling operation, the independent dehumidification mode efficiently removes humidity from the space without lowering the temperature

When the heat mode is started the fan speed is automatically regulated from the lowest level to the preset level according to the temperature rising of the evaporator. This prevents a blast of cold air being released upon start up
