RynoWorx 18" x 48" Modular Mini Infrared Asphalt Heater - Version 1 - R4-IR-V1

The RynoWorx R4-IR-V1 Infrared Asphalt Heater is designed for contractors handling larger pavement repairs, continuous repair sections, commercial parking lots, municipal work, and higher-volume asphalt maintenance.

The R4 uses a 100,000 BTU infrared heating system to soften existing asphalt so damaged material can be reworked, supplemented where needed, compacted, and blended back into the surrounding pavement instead of completely removing and replacing the repair area.

RynoWorx’s newer catalogue specifies a 19" × 51" heating area, approximately 6.7 sq. ft., with an 8-minute heat cycle to approximately 325°F. It is rated for roughly 25–40 repairs per day depending on job size and working conditions. RYNOWORX 2026 PRODUCT CATALOGUE…

The R4 is also RynoLink compatible, allowing multiple compatible heaters to be connected together for substantially larger repair areas.
