Innovative SiC Inserts Technology

The Problem with Traditional Radiant Tubes
In a standard radiant tube, the burner leg releases up to 45% more energy than the exhaust leg. This is because:

• Burner Leg: Benefits from both radiation and convection heat transfer from the luminous flame.

• Exhaust Leg: Relies primarily on convection alone, as hot gases have a very low emissivity (~0.05), leading to inefficient heat distribution and wasted energy.

Our Solution: Patented Twisted "Y" Design
ZG Industrial's SpyroCor™ SiC inserts transform this inefficient system. The innovative twisted "Y" design creates a non-turbulent, high-convection flow that maximizes heat radiation.

How It Works & Saves Fuel
Installed in the critical last two-thirds of the exhaust leg, our inserts act as a high-emissivity engine:

1. Dramatically Increases Emissivity: The SiC material boasts an emissivity of 0.95, turning the exhaust leg into a powerful radiant heat source.

2. Balances Heat Transfer: Both radiation and convection are now present throughout the tube, balancing the heat output between the burner and exhaust legs.

3. Delivers Proven Efficiency: This balance allows for a direct reduction of burner input by up to 20% while maintaining the same total energy transfer to your workload.

Key Benefits at a Glance:

• 20% Fuel Savings: Directly lower operational costs.
