Compress 3400i Outdoor Unit and Tower Unit Professional

Compress 3400i Outdoor Unit and Tower Unit overview

Super efficient and flexible heat pump solution.

Our CS3400i AWS is available in 4, 6, 8 and 10kW outputs. Our quiet, space-saving outdoor units are suitable for renovation (building dependent) and new build projects providing a solution for maximising garden space.

The pre-configured indoor unit is quick and easy to install with a built in multi- functional back up electric booster for heating and hot water.

Bring boilers and heat pumps together with the hybrid unit that can be coupled with our 4-8kW outdoor units.
