Energy Efficient Dehumidifiers

With over 300 operatives working on the London Bridge Station Redevelopment, our welfare facilities and drying rooms, that are used for both day and night shift working, require constant heating and cooling to allow for a comfortable climate and adequate drying facilities.

Given the high demand for the requirement of heating and cooling, it was recognised that this would be extremely energy intensive for the 6 year duration of the redevelopment project.

London Bridge are committed to reducing energy usage and operational costs and therefore sought energy efficient dehumidifiers for the new welfare rooms.

The EL-Bjorn A155HW dehumidifier uses a water based auxiliary heating system that quickly raises the temperature in the room using softer air flow in comparison to traditional heating.

By providing short drying times this unit showed energy efficient benefits and reduced costs for the project.

To exemplify these benefits, a whole life comparison study was carried out between the water based auxiliary heating and cooling system and the standard dehumidifier.

The study confirmed that fantastic savings were being made by using the water based dehumidifier as it emitted 50% less carbon and used 40% less kWh per week in comparison to the standard unit.

Looking at this from a whole life perspective, with two dehumidifier units in our welfare facilities, we would see a payback period of as little as 14 weeks with an anticipated total whole life saving of over £14,000.

These units have proved both cost effective and a sustainable solution at London Bridge.
