Rinnai Commercial Natural Gas Rice Cooker, 55-Cup - RER-55AS

The Rinnai RER-55AS is a high-capacity commercial natural gas rice cooker for batch rice production in restaurants, sushi bars, cafeterias, catering operations, and other high-volume foodservice kitchens. It cooks 25–55 standard 180 mL cups of uncooked rice per batch, yielding up to approximately 110 cups of cooked rice, with cooking times as low as 20 minutes.

A 35,000 BTU natural gas burner combines thermostat control with an automatic two-stage burner and simmer cycle for consistent bulk rice cooking with less operator intervention. The main burner shuts off automatically when cooking is complete, while a flame-failure safety device provides gas-operation protection. An aluminum cooking pot, enameled commercial casing, stainless steel lid, and NSF and CSA certifications reinforce its role as dedicated restaurant rice-production equipment rather than a residential rice cooker.

The Rinnai RER-55AS natural-gas rice cooker handles 25–55 supplied cups of uncooked rice per batch. The 180 mL rice measure and marked aluminum pot help restaurant teams set up repeatable batches for rice bowls, plated meals and other high-volume service.

A 35,000 BTU/h natural-gas input supplies the cooking heat. The cooking control rises and the main burner shuts off when the cooking stage ends. Leave the lid closed for the manufacturer’s additional 15-minute minimum rest with the pilot lit before serving. Follow your establishment’s food-safety procedures for any holding after cooking.
