Deep dives
Recirculation vs open exhaust
Loring S7 Nighthawk recirculates hot gas — exhaust temperature drops and afterburner load shrinks.
Open-drum platforms vent more heat per batch. Model your gas meter at 50% and 75% charge before signing.
IR radiant heat transfer
Diedrich IR drums radiate through a double-wall — different first-crack timing than convection.
Operators switching from Probat or Giesen need 15–20 calibration batches, not a copied profile.
Electric vs gas site work
Stronghold S9 X skips gas permitting — but panel upgrade may equal gas line cost.
Get MCA off the nameplate and a load calc from a licensed electrician before lease signing.
What to verify with your dealer
Neither OEM publishes binding street prices — quotes move with queue and freight.
