Frequently Asked Questions
Yes, but recirculating systems must carefully manage inlet temperature. Since the Flow Torch 600 has a maximum inlet temperature of 392°F (200°C), systems designed for recirculation need temperature monitoring to prevent unintended preheat accumulation. Many customers add a secondary high-limit sensor upstream to protect the heater.
