  • Time to thaw: In-house testing finds DEF within hose warms from −40°F (−40°C) to liquid (ca. 32°F, 0°C) in 3 minutes of full duty power.
  • Hoses: Two EPDM hoses (SAE 20R3EC) with SAE J2440 push-to-connect fittings:
    • A Hose: 3/8" inner diameter, ℓ 10 ft 3 in. (312 cm).
    • B Hose: 5/16" inner diameter, ℓ 10 ft (305 cm).
  • Voltage: 24 V nominal.
  • Current draw: 
    • Full duty 375 mA/ft (1.23 A/m), total 7.5 A.
    • Temperature maintenance: 0.18 duty (total 1.35 A) at −40°F (−40°C). Less at higher temperatures.
  • Wattage: Full duty 9 W/ft (30 W/m), total 182 W.
