AIR 10i, 14i, 22i

Speed-controlled air-to-water heat pumps, models 10i-22i, 2.5-22 kW.

AIR 10i, 14i, 22ND AIR-i is a series of ultra-efficient, speed-controlled air-to- water heat pumps which automatically adapt to the heating needs of houses, properties or small industrial premises during the year. When high output is required, the output increases. When less output is required, the compressor shifts to lower output. This means that you will always achieve maximum savings.

ND AIR-i is optimized to make the best possible use of eco-friendly energy in the air. It converts energy in the air into heating and hot water, and does not require boreholes or coils in the ground. ND AIR-i has automatic defrosting, which results in more heat, more power and a longer service life. ND AIR-i is equipped with a condensation tray with a built-in heater as standard.

ND AIR-i should always be installed with one of our indoor or control modules for best results. We recommend ND BASE 350i for control and hot water. To make heating and hot water adjustment easy, all of our indoor modules have colour touchscreens.

The ND BASE 350i indoor module is equipped with a highly efficient water heater, which produces over 300 liters of hot water. If you use a lot of water, you can connect ND AIR 22i to the ND BASE 550i Pro all-in-one multi-tank. It has a hot water capacity of more than 600 liters, which is enough for 15 shower-loving teenagers.

If you wish to connect the ND AIR-i to your existing installation, complement with the ND LOGIC control module. A unique control system that monitors and controls ND ’s heat pumps, additional heating, buffer tanks, pools, cooling, etc. for up to four different heating systems. If the energy requirement is particularly large, up to ten pumps can be run together.

All ND heat pumps and boilers are designed, developed and manufactured in Sweden. This gives us total control of all stages of the production process – from manufacture up to delivery of the finished product.

Control units compatible with ND AIR 10i-22i – refer to individual product sheets for more detailed information.
