Continuous Fryer Heat Source Selector
Electric, gas and thermal-oil heating are all available on the ST-YZJ range. They differ on how tightly they hold temperature, how fast they recover after loading, and what they need from your plant. Answer four questions and the tool states which fits and what it costs you.
Your Requirement
Standard palm oil should not be pushed past 363 °F (184 °C), the point at which the oil begins to crack, and the ceiling differs by oil.2
The Three Options Side by Side
| Heat source | Temperature stability | What it needs | The trade-off |
|---|---|---|---|
| Electric | Indirect-heated systems hold to about ±2 °F, the tightest of the three1 | Electrical supply sized for 120–180 kW at 380 V / 50 Hz | Highest demand on your electrical supply; energy cost depends on local tariff |
| Gas | Direct gas-fired systems swing 10–15 °F1 | Gas connection, combustion air and flue | Recovers temperature faster after loading, but the widest band of the three |
| Thermal oil | Thermal-fluid systems swing 7–10 °F1 | Heat exchanger circuit and pump; suits plants with an existing thermal-oil loop | Large pipe surface area removes hot spots while holding temperature accurately,2 at the cost of an extra circuit to maintain |
Whichever you choose, the operating rules are the same. Do not run the fryer below 80% of nominal capacity, and if production halts for more than 30 minutes drain the fryer and cool the oil rather than circulating it hot with no product.2
