Swirl Cartridge Heater Manufacturer

Frequently Asked Questions

• Q: How does a swirl heater work?

• A: It has an internal spiral baffle. As fluid is pumped through the heater, the baffle forces it to spin rapidly. This turbulence breaks up the boundary layer around the heating element, allowing for much faster and more even heat transfer.

• Q: What are the main benefits over a standard screw plug heater?

• A: The main benefits are higher efficiency (less energy to heat the fluid), self-cleaning (less maintenance), and a more compact design for the same heating capacity.

• Q: Do I need a pump to use a swirl heater?

• A: Yes, a swirl heater is designed for forced circulation applications. A pump is required to push the fluid through the heater at a sufficient velocity to create the turbulent flow.

• Q: Can these heaters be used with dirty or sludgy fluids?

• A: Yes, this is one of their key advantages. The self-cleaning swirling action helps keep the heater element clean, even when heating fluids that contain suspended particles.

• Q: What information do I need for a quote?

• A: Please provide the fluid type, desired flow rate (GPM or L/min), inlet and outlet temperatures, available voltage, and the desired connection size/thread type.

• Q: Can you make them from corrosion-resistant materials?

• A: Absolutely. We can manufacture the entire heater, including the sheath and body, from materials like 316 stainless steel or Incoloy to resist corrosive fluids.

• Q: What is the pressure and temperature rating?

• A: This varies by size and construction. We can design them to handle pressures up to 3000 PSI and temperatures up to 750℃, depending on the materials chosen.

• Q: Are they difficult to install?

• A: No, they are installed much like any other inline heater. They have standard threaded or flanged connections that are welded into your piping system.
