Atosa USA ATFS-40ES-NG Natural Gas Floor Fryer, 40 lb, 3 Burners, 66,000 BTU, Stainless Steel
Atosa USA ATFS-40ES-NG — 40 lb Natural Gas Floor Fryer
The ATFS-40ES-NG is the workhorse 40-pound fryer: three heavy-duty burners producing 66,000 BTU/h under a welded stainless steel tank, with a millivolt thermostat holding oil anywhere from 200°F to 400°F. A cool zone in the bottom of the tank drops crumbs out of the cooking area instead of burning them, which is the single biggest factor in how long a batch of oil actually lasts.
Key Features of the ATFS-40ES-NG
A fryer lives or dies on recovery time, oil life and how safely it fails. These are the build details behind all three.
Three 22,000 BTU Burners
Each burner contributes 22,000 BTU/h for 66,000 total, with independent manual control and a standing flame on standby pilots — strong recovery when a full basket of frozen product hits the oil.
Cool Zone Extends Oil Life
The oil cooling zone sits below the burner path at the bottom of the tank, capturing crumbs and sediment where they will not carbonize — cleaner oil, less off-flavor and fewer change-outs.
Millivolt Thermostat, 200–400°F
A high-quality millivolt T-stat holds the selected temperature automatically across the full 200°F to 400°F band, so fries, chicken and delicate product all get their own correct setpoint.
Layered Safety Systems
A safety valve with automatic voltage stabilizing and a self-reset high temperature limiting device shut the gas down before oil can reach a dangerous temperature — and reset without a service call.
Two Baskets and Crumb Screen
Ships with two nickel-plated baskets with coated handles, a wire mesh crumb screen and a basket hanger — the full working set, not a bare fryer you have to accessorize.
Welded Tank, Four Casters
The tank is welded stainless rather than folded and sealed, and the unit rolls on four casters so it pulls out of a battery for filter-day cleaning without dismantling the line.
Gas supply note: this is the natural gas version, set for 4" W.C. intake pressure and supplied with a matching 4" w.c. regulator on a 3/4" NPT rear connection. The propane version is a separate model (ATFS-40ES-LP, 10" W.C.) — order the one that matches your building's gas service rather than planning to convert it.
Ideal Applications
Forty pounds is the standard single-fryer size for most independent kitchens — enough throughput for a full menu without the oil cost of a 75 lb pot.

Frequently Asked Questions
Can this fryer be converted to propane?
The ATFS-40ES-NG is built and regulated for natural gas at 4" W.C. Atosa sells the propane version as a separate model, the ATFS-40ES-LP, set for 10" W.C. Order the version matching your gas service.
What does the cool zone actually do?
It is a section at the bottom of the tank below the heat path. Crumbs and breading fall into it and stay well under frying temperature instead of carbonizing in the oil, which keeps the oil cleaner, tasting neutral and usable for longer.
Does it come with baskets?
Yes. Two nickel-plated baskets with coated handles are standard, along with a wire mesh crumb screen and a basket hanger.
How does it compare to the ATFS-50ES and ATFS-75ES?
All three share the same 30-1/8" depth and controls. The ATFS-40ES has 3 burners and 66,000 BTU/h in a 15-1/2" cabinet; the ATFS-50ES has 4 burners and 88,000 BTU/h in the same width; the ATFS-75ES steps up to 5 burners, 110,000 BTU/h and a 21-1/8" wide cabinet.
What gas connection does it need?
A 3/4" NPT connection at the rear of the unit. A 4" w.c. regulator is supplied with the natural gas model.
Can it be installed on legs instead of casters?
Yes. Four casters are standard, but Atosa offers a leg kit, part number 301110006, for installations that call for fixed legs.
