The Sentinel HD55 Dehumidifier is an excellent unit for crawlspaces, cellars and basements. It is robust, compact and versatile

The main benefits for all the Sentinel range is that the machines can be controlled remotely. A controller plugs into the unit via a Cat 5 cable. The controller displays the temperature and humidity in the environment that is being controlled.

The machine can be operated in two modes. Both the controller and the HD55 unit have a Humistat in them and you can set the controller to work from either humistat.

Mode One: Controlling on the HD55 Humistat.

In this mode you could have your machine in the basement and control the humidity and monitor your basement conditions on the remote control unit which could be in a different room above the basement. You can alter the RH from the comfort of your living room!

Mode Two: Controlling on the remote control Humistat.

In this mode you could have your dehumidifier outside the room space you want to control and duct the air to the room. This would work in a similar way to your central heating system and thermostat as you don’t have your boiler in the room (it is remote) but you want to control the temperature in the room via your thermostat.

The unit has a gravity water outlet feed allowing it to be situated above a collection vessel or above a collection point. Alorair Solutions UK can also provide pumps to remove the condensate from cellars and basements if required.

Please go to the accessories page for the remote control unit and ducting pricing.
