The Quiet Drive is widely regarded as one of the most efficient and reliable solid-state systems available today. See the Solid State Relay tab for more detailed information for why this feature is so critical to your new glass kiln's performance and longevity.

Relay Access Port

The GTS 17 incorporates Evenheat's Relay Access Port for simple, no-panel-off relay replacement. Why is this important when this kiln doesn't have mechanical relays?

That's because the solid state units utilize a mechanical relay to work as a safety relay.

This is a very smart design. Technically, solid states are never fully on or fully off, meaning without a physical/mechanical contact, there would be leakage current from the Solid State going to the elements, barely noticeable but still present. Disrupting the circuit with a physical contact ensures there is absolutely no leakage. The mechanical relay on a Solid State unit actuates one time when the program is started (allows current to reach Solid State and begin firing), and one time when the program ends (cuts all current to Solid State to stop firing). There are no expectations to ever have to replace the safety relay, but if for some reason it becomes necessary then having this Relay Access Port makes life really easy. Now, that's smart!

Benchtop operation

The GTS 17 offers versatile placement options—set it directly on your counter or bench-top, or use the included floor stand (details below). The choice is yours!

Important: Ensure that your counter or bench-top is made of non-combustible material and is sturdy enough to safely support the kiln's weight.

Elemented Fiber Lid

The lid of the GTS 17 is crafted from a specialized fiber material, offering outstanding thermal performance while keeping the lid lightweight and easy to handle. This design allows the heating elements to be placed directly on the surface, ensuring maximum heat transfer and firing efficiency.

To enhance durability, the lid heating elements are carefully positioned horizontally (left to right). This thoughtful arrangement prevents sagging or bunching over time, even with repeated opening and closing. It’s a small but crucial detail that ensures reliable performance and long-term satisfaction.

Floor stand - yes, it's included!

The GTS 17 is supplied with a 16" stand for optional floor placement, if desired.

Maintenance Parts Tag

To make maintenance a breeze, the GTS 17 includes a convenient parts tag that lists the correct Evenheat part numbers for commonly replaced items.

It's a simple yet invaluable addition that takes the guesswork out of ordering maintenance parts.

Power Interrupt Switch

The GTS 17 comes standard with a power interrupt switch that automatically cuts off electrical power to all heating elements if the lid or chamber is opened.

This feature is essential for those who need to access the kiln during firing, such as for glass manipulation or roll-ups, ensuring safety and peace of mind throughout your creative process.

Choose the voltage that matches the electrical service where the kiln will be installed. Some kilns are available in only one voltage, while others can be ordered in multiple voltages. If both 120V and 240V are available, 240V is generally the preferred choice because it places less demand on your electrical system, while 120V offers the convenience of operating on a dedicated standard household circuit. If both 208V and 240V are available, select the voltage that matches your building's electrical service—240V is most common in homes, while 208V is common in many commercial, educational, and institutional buildings. If you're unsure which voltage you have, confirm it with your electrician before ordering.

Your kiln must be built to match the electrical service where it will be installed. Choose single-phase if that's what your building has (almost all homes do). Choose three-phase only if your building has three-phase power available. If both are available, three-phase is generally the preferred option. If you're unsure, verify the available electrical service with your electrician before placing your order.

Mechanical relays are standard and reliable. Solid-state relays (SSR) offer silent operation, faster cycling, greater precision, and longer lifespan—ideal for frequent or high-accuracy firings.
