Severn – High Temperature Water Source Heat Pump

The Severn can generate up to 180F leaving water for your system. This can either be for comfort heating or domestic hot water. The Severn SWH model is designed and built with double walled vented heat exchanger.

Six models have capacities ranging from 60 to 1000 MBH.

The source can be a number of modes, such as ground source, cooling tower water, or any other source where the Severn can be used in a heat recovery application. Thereby not only performing the heating load, but also generating chilled water for the process. Thereby doubling the overall COP. Source loads can have high or low entering water temperature.

The units are front serviceable. This means the heat pumps can be installed side by side. Also, they can be mounted against a wall or have two rows back-to-back.

The pipe headers are accessible from the front. This would result in a substantial amount of MBH/ft2 inside a mechanical room.

The heat pumps are 34” wide so they will fit easily through door ways and elevators. They can be moved using a dolly (hand truck). Even up/down stairs.
