3 Theory of Operation
SSHLV Series gas fryers utilize a welded, stainless steel fryvat that is directly heated with high
efficiency, atmospheric burner tubes. The atmospheric burner tubes eliminate the maintenance heavy
and inefficient (over time due to clogging) blowers used in other fryers. Heat tubes provide as much as
80% more surface area for heat transfer than open vat fryers (tubeless), providing faster recovery
without scorching the oil. Each tube, four total, is fitted with proprietary, incoloy baffles that are heated
by air/gas jet emitted from our patented burners. The baffles transfer heat to the fryvat by means of
infrared radiation and conduction plus convection flow from the air/gas jet. The tubular heat also allows
for a “cold zone” below the tubes where cooking debris will settle at t temperature much lower than the
cooking temperate. The lower temperature prevents the debris from carbonizing and oxidizing the
cooking oil prematurely as typically found in non-tube style fryvats. In full-vat units, gas flow to the
burners is regulated by one electromechanical gas valve. In split-vat units, each burner bank has its
own valve to independently control each vat. All fryers in this series are equipped with 24 V AC gas
valve systems, and all are configured with matchless ignition.
3.1 The Matchless Ignition System
An ignition module, mounted behind the gas valve, is connected to an ignitor/pilot assembly between
the burners. The ignition module performs three important functions: provides an ignition spark,
supplies voltage to the gas valve, and proofs the pilot flame. The module employs a four second time
delay circuit (after flame sense) and a signal that activates the gas valve. Two types are currently used:
A closed-box design is used in most fryers, but in some fryers built for export, the module is packaged
differently. A single “one-spark” module is used on current production full-vat fryers. All dual-vat fryers
use two single “one-spark” modules. The ignitor/pilot assembly consists of an igniter, a pilot tube/hood,
and a flame sensor.
