Here at High Tech Insulators, we understand the rugged needs of the explosion proof mining industry. Our products can meet the strictest safety standards and are built to the rugged conditions needed in the field. Our insulation increases the safety and efficiency of your mining equipment by insulating your engine’s manifold and exhaust systems so they will maintain a surface temperature below 150 degrees Celsius. The effects are extraordinary; By insulating your engine you will see marked improvement in horsepower as well as safety. This means fewer accidents and better profits. Also, by reducing the engine surface temperature so dramatically, your staff will be able to repair your engines more quickly without using an engine blanket.
Mining environments are full of flammable and explosive materials. Many of these are difficult to observe and monitor. They have no scent and are rarely visible. The simple starting of a motor can ignite these gases and can result in loss of property, injury, or even death.
