Description
The Frymaster MJ340 is a triple open-pot commercial gas fryer system designed for foodservice operations requiring increased frying throughput, dependable recovery performance, and simplified maintenance. Each frypot provides 43 lbs of oil capacity and uses Frymasters Master Jet burner system to deliver efficient heat transfer and even heat distribution around the frypot, supporting consistent frying results for French fries, pre-breaded foods, snack items, and other high-demand menu applications. The open-pot design simplifies cleaning and maintenance, while the deep cold zone and forward-sloping frypot bottom help separate sediment from the cooking area to maintain oil quality and improve frypot sanitation.
Designed for operational simplicity and long-term reliability, the MJ340 utilizes millivolt controls that require no electrical connection for standard fryer operation. A centerline fast-action temperature probe helps maintain accurate oil temperatures for fast heat-up and recovery, while the Master Jet burner system eliminates the need for burner cleaning or air shutter adjustments. Stainless steel construction, EZ Spark push-button ignition, and triple-frypot battery configuration make the MJ340 a strong solution for restaurants, concession operations, cafés, and commercial kitchens requiring dependable multi-fryer performance with low maintenance demands.
