NORPRO provides sales, installations, and complete parts and service for a wide variety of production and automation equipment for asphalt plants. We also custom build equipment and systems for special applications. Some examples of the things we do -




Chemical Only WMA Skid
  • Norpro Warm Mix Systems - Proven technology to help you lower mix temps, save on dryer fuel costs, and improve the workability and compaction of mixes at lower lay-down temperatures. Norpro can provide warm mix systems as either water inject/foaming only, chemical inject only or combo systems with the flexibility of either water foaming or chemical inject both on-board. Our systems are reliably simple, efficient and very economically priced. Each system is supplied complete with all necessary hoses, fittings and the easy-to-install Norpro in-line mixing chamber for your AC delivery line. Systems can be provided as either compact skid-mounted, or as a complete trailer mounted package for the ultimate in portability and fast jobsite setup. Trailered systems come complete with holding tank, interior lighting and heat for cold weather operation.

Electric Fuel Pre-Heater
  • Electric Fuel Pre-Heaters - Designed for the operation that is firing on heavier fuels and needs to boost the fuel temperature prior to delivery to the burner. Built for simple, efficient, reliable and safe operation.
Electric Hot Oil Heater
  • Electric Hot Oil Heaters - For plants that have full-time commercial power available, an electric hot oil heater system can be an economical choice for keeping your plant and storage tanks up to temperature. Simple and reliable by design, they can eliminate a lot of nuisance problems often associated with older fuel-oil fired heat systems. Our latest models now incorporate a touch-screen control panel that has the capability of being remotely accessed over the internet by either computer or smart-phone. Why send your plant operator out to the plant in the middle of the night to check on the heater when he can simply dial it up, make sure the heater is running, turn it on or off and even adjust the setpoint temperature - all by remote access control !
