Dilute Phase Pneumatic Conveying

The Economical Way to Convey

Dilute phase pneumatic conveying is a means of transferring dry powdered or granular bulk materials through a pipeline. From sorbent injection to truck unloading to all manner of general applications requiring transfer of powdered or granulated bulk materials, dilute phase pneumatic conveying is another proven technology Nol-Tec provides.

Nol-Tec’s Dilute Phase Pneumatic Conveying – the difference

Our Dilute Phase Pneumatic Conveying Systems utilize large amounts of low-pressure (<15 PSIG) or vacuum high-velocity (3,500-9,000 ft/min) air to transfer powdered or granular bulk materials through enclosed convey lines in an airborne state. Dilute phase systems are extremely cost-effective and ideal for handling durable, non-abrasive, or light materials.
