HJ4520A Sprayer (With built-in Heater)

Spray grade modified bitumens and cut-back asphalts respond favorably to temperature increase. The viscosity of the fluid becomes more efficient and allows it to be delivered through longer lengths of hose and with greater effectiveness at the point of airless atomization. The Hennes-Johnson Model 4520A with built- in heater provides a steady 20 - 25 degree boost in fluid temperature giving you peak performance from a single component package. The 4520A with built-in heater includes all of the standard features found on the Hennes-Johnson model 4520 including the rugged 630cc Honda engine and Xtreme pump system combination.
