Surface Tech Offers DFNDR Dosing Systems
BY AsphaltPro Staff

The DFNDR is the latest evolution of a line of dosing systems offered by Surface Tech, San Diego. This model is fully encased, easy to set up and run, and fully automatic, according to the company. The redesigned and enclosed system is compact and allows for set-up anywhere in an asphalt plant. Producers will find it most useful when housed and set up permanently with a 120V power source and a steady 110 psi air supply, according to the company.
A programmable logic controller (PLC) continually measures the weight of any Surface Tech aramid product and/or length fed through the hopper and compares it to a desired target rate based on the plant’s production needs. Constant measuring ensures a consistent, uniform feed of the Surface Tech aramid into the mix. The company reports that producers will have no fly-away mess to deal with, and they’ll achieve a mix that contains the precise amount of 2.1 ounces of aramid per ton with no clumping.
“We have devoted many hours of study, field trials, and engineering to bring the DFNDR to the highest level of automation and accuracy available. It offers a dosing technology that asphalt producers can rely on with confidence,” said Steve Santa Cruz, President of Surface Tech. The DFNDR meets ISO 9001:2015 standards and is UL Listed. It’s made in the USA by HIS Innovations Group. Surface Tech provides training and support to ensure each job meets the desired specifications.
