Probably the most technically advanced mid-sized water well drilling rig operating in the UK today, our new Conrad Combi 500 is a state of the art
machine. It’s powerful and effi cient modern engine is compliant with the highest emissions standards, making it one of the cleanest rigs in the business.
It’s smart, too. Intelligent power management automatically reduces engine rpm to stationary when no function is operated for 5 seconds. Equipped with remote controlled hydraulic functions, designed to eliminate manual handling, also provides a safe working environment.
The reduced noise and exhaust emissions, coupled with the ability to operate in an incredibly small footprint, make WJ and our Conrad rig the ideal solution for installing wells up to 500mm diameter and up to 200m depth in restricted urban sites.
