The Imperial IRT-18-LP is a gas, floor-standing commercial rethermalizer, not an oven or fryer, built for indoor use in high-volume kitchens. It has a 16-gallon water capacity, four tube-fired burners, and 140,000 BTU output, with plumbed water connection, through-the-body drain, and mobility on four 6" casters with two brakes. Standout specs for comparison are the stainless steel vessel/exterior, hinged cover, auto-fill with rapid fill bypass, overfill protection, temperature limit switch, and a preset 200°F thermostat; it runs on propane and requires professional installation, so it suits restaurants, catering, and institutional service rather than light-duty prep.
