The GreasePak Battery Operated Dosing Module is a wall-mounted, self-contained unit that automatically dispenses a bio-enzymatic solution into commercial kitchen drain lines. Its purpose is to break down fats, oils, and grease — collectively referred to as FOG — before they accumulate and cause blockages or drainage failures. The unit holds a 5-litre reservoir and runs entirely on battery power, requiring no mains electrical connection.FOG build-up is one of the more persistent and disruptive maintenance problems in commercial kitchens. Slow or blocked drains interrupt service, generate odours, and can create compliance issues under BS EN 1825, the standard governing grease management in commercial kitchen drainage. The GreasePak module is tested to this standard and carries BBA approval, which means water authorities and environmental health inspectors generally accept it as a compliant approach to FOG management — particularly where a traditional passive grease interceptor is not installed or is not a practical option for the site.Key operational advantages include: Automatic dosing maintains consistent drainage treatment without relying on staff action Battery operation removes the need for a mains supply close to the installation point Bio-enzymatic action continues working between service periods to break down residual FOG Helps reduce drain odours in kitchen and front-of-house areas BBA approved and tested to BS EN 1825 for compliance confidence Installation is straightforward — the unit mounts to a wall and doses directly into the drain line. The battery-powered design offers useful flexibility in positioning, particularly in areas where running a cable would be awkward. It is worth checking with your local water authority or environmental health officer whether a dosing unit alone satisfies your specific compliance obligations, as requirements can vary depending on site type and waste volumes produced.This unit is well suited to cafés, pub kitchens, restaurant prep areas, and similar smaller to medium-volume operations where a full grease interceptor is not in place. For higher-output sites producing significant volumes of FOG waste, a higher-capacity solution would be worth considering.If you are unsure whether this unit is the right approach for your site's drainage compliance, we are happy to talk through the options with you.
