Upgrade to Ecosmart AIR – The Smarter Standard in Hybrid Welfare
Join the UK’s largest plant hire companies already using Ecosmart AIR to power their fleets. With lower running costs, reduced emissions, and superior comfort, this is the next generation of hybrid welfare units for sale.
Why Choose Ecosmart AIR?
Whether you’re a fleet operator, hire company, or site owner, the Ecosmart AIR gives you the perfect balance of efficiency, sustainability, and user comfort.
The Ecosmart AIR takes the standard hybrid system one step further with heating independant from the generator.
Using a Webasto AIR diesel heating system (fully HVO-compatible), it provides reliable warmth without needing the generator to run — perfect for busy sites or high staff rotation where comfort, uptime and low noise are essential.

Ultra-low emissions with HVO fuel

*Based on 10 hours per day for 260 days, 80 days in winter mode and 180 days in summer mode.
Each day is a typical usage day.
Solar panels achieve maximum output in direct sunlight, but they work in normal daylight and cloudy weather too. The amount of power a solar panel or charging kit generates in cloudy weather will be lower compared to direct sunlight. Also the positioning of the cabin will affect the solar charging of the batteries i.e. under trees, etc.
This assessment doesn’t take in consideration the usage of the hydraulics. This assessment is guidance only.
