 HydroGuard™ Makes Sure That Oil and Water Don't Mix D-A HydroGuard™ is designed to separate and shed water in applications where water is inevitable. Whether it is a result of a working environment, such as in a dredging operation, precipitation or moisture condensation, water can get into the lower gear case of a crane's travel mechanism and contaminate the gear lubricant. When compared to conventional automotive gear oils, HydroGuard ensures protection of gears in wet applications. More info. |

 D-A's eco-drill™ Protects Your Drilling Operation While Being Environmentally Friendly. As a biodegradable rock drill lubricant, D-A eco-drill™ is specially designed for use in extreme working conditions with percussive pneumatic tools, down-the-hole (DTH), and surface drilling equipment. This lubricant begins with naturally high viscosity index base oils for temperature shear stability and is formulated with our advanced ChemGuard additive technology. D-A's ChemGuard™ innovative formula has a vigorous EP/antiwear inhibitor that reduces welding or scoring in a constant shock load environment. It also protects against rust and corrosion in adverse high load situations. D-A eco-drill™ has a built-in emulsifier for severe circumstances where water and compressed air coexist. A robust tackifier is added for the desired adhesiveness that protects against undesired misting or when water spray is present and sustains its strength where superior lubricity is expected. D-A eco-drill™ is rigorously tested for its performance as well as its environmentally safe components. This product is highly recommended for use in monitored or environmentally sensitive locations. D-A eco-drill™ may also be utilized in Mining and Tunneling, Jack-Hammers, Paving Breakers, Chippers, Tampers, Scalers, Impacters, Roofbolters, Screamer Pumps, and Water Injection Plunger Pumps.
