Why Artists Love the GTS 41:

Massive Workspace for Maximum Creativity
Whether you're working on architectural panels, casting molds, or large platters, the GTS 41 provides unmatched firing area and a clean, studio-ready footprint. No need to split projects between firings—just go big and get it done.

Hybrid Build for High-End Results
The fiber lid offers quick, efficient heating while minimizing shedding. The firebrick body stores and gradually releases heat, helping maintain a smooth, consistent annealing curve.

Enhanced Safety and Efficiency
The Power Interrupt Switch cuts all power when the lid or chamber is opened—perfect for artists performing mid-cycle manipulations. The new Two-Position Venting System gives you greater control over adhesive burn-off and cool-down speeds.

User-Friendly Design from Top to Bottom
From the wide lid handle and spring-loaded lift assist, to the intuitive Swing View Control Enclosure, every aspect of the GTS 41 is designed with artists in mind. No awkward angles. No unnecessary strain. Just smart, thoughtful engineering.

Solid State Reliability
The Quiet Drive Solid State Relay system is now standard, replacing outdated mechanical relays with silent, accurate, and low-maintenance technology. No clicks, no failures, and no worries—just consistent performance, every time.

Maintenance Made Simple
The Relay Access Port means you’ll never need to remove panels to service your kiln. Just a screwdriver gives you access for easy replacement—saving you time and frustration down the road.

Controller Options:

Choose the control system that matches your firing style:

• TAP II – Full-featured, Wi-Fi-enabled touchscreen

• Icon / Icon+ – Streamlined and user-friendly touchscreen interfaces

• Rampmaster III – Reliable 12-key digital interface (non-touchscreen option)

All Evenheat controllers include a Special Limits thermocouple for enhanced temperature precision and a non-metallic faceplate for better Wi-Fi connectivity.

Optional Mobility – Rolling Base Add-On:

The GTS 41’s base comes pre-drilled for caster installation. Simply attach the wheels during setup—no special frame or extra parts needed. Want to wait and install them later? No problem—it’s easy either way.
