3" Firebrick with No Loss in Chamber Volume

As the narrative of kiln design unfolded, the 2-1/2" firebrick played a foundational role. Nevertheless, the emergence of high-temperature requirements took the spotlight, leading many kiln manufacturers to alter their direction. They chose to reduce the size of the firing chamber to accommodate the thicker insulation while keeping the kiln's external dimensions unchanged.

In contrast, Evenheat embarked on a distinctive journey. Instead of diminishing the chamber's size, they maintained its generous interior space and expanded the external dimensions. This innovative approach safeguards the chamber's capacity, ensuring a seamless fit for standard kiln furniture. This thoughtful design decision reflects a commitment to preserving compatibility and user-friendliness.

Swing-Away Peephole Covers

Evenheat's kiln designs welcome swing-away peephole covers, departing from the customary use of plugs.

With ease, users can remove the access plate to gain direct access to the mechanical relays, bypassing the need to remove the control panel or navigate intricate internal wiring. This process is remarkably straightforward and efficient, requiring only a screwdriver.

Acknowledging that mechanical relays may encounter issues over time, Evenheat's inclusion of the relay access port proves to be an invaluable resource during such circumstances.

While Pottery Pulse highly recommends the Quiet Drive Solid State Relay system, for those mindful of budget constraints, this feature remains a practical and accessible choice.

Single Maintenance Line

Evenheat firmly adheres to the use of a solid stainless jacket design. This choice signifies exceptionally robust construction—free of gaps, shifts, and engineered for lasting durability.

In their deep 27" High Fire models, Evenheat introduces what they term a "maintenance line." This innovative feature allows for the chamber to be partially disassembled to facilitate maintenance and delivery requirements.

The Maintenance Line is securely held in place through the utilization of stainless steel plates and screws. By simply removing these screws, you can effortlessly separate the sections for maintenance or installation purposes.

In stark contrast to the use of buckles, which are prone to loosening and permitting shifting during loading, unloading, and use, this method guarantees stability and unwavering reliability.

The HF 2927 offers a diverse selection of Multi-Zone control options, including the RampMaster II, Icon+, and TAP I. These Multi-Zone controls rely on multiple thermocouples (temperature sensors) to ensure exceptional temperature uniformity within the firing chamber.

When delving into Relay Technology, it becomes evident that Solid-state relays (SSRs) offer a robust and reliable alternative to conventional mechanical relays, which are prone to wear due to their moving parts and electromagnetic coils. SSRs employ a solid semiconductor mechanism, eliminating mechanical wear and offering significant advantages in kiln temperature management.

Advantage 1 - Exceptional Durability: SSRs are celebrated for their extended lifespan, resistant to the mechanical wear and electrical arcing often associated with mechanical relays. The familiar clicking sound from kilns, signifying the operation of mechanical relays, can lead to wear and costly repairs over time. In contrast, Evenheat's SSRs provide silent and reliable operation that seamlessly integrates with your kiln.

Advantage 2 - Superior Temperature Precision: Mechanical relays have limited cycling frequencies to extend their lifespan, whereas SSRs can cycle as frequently as 120 times per second. This enables swift adjustments and unmatched temperature precision, benefiting all Evenheat controls, including the standard Icon controller, to ensure precise temperature control.

Advantage 3 - Prolonged Heating Element Life: SSRs incorporate Zero Crossing technology, engaging and disengaging at the zero-voltage point of AC power cycles. This significantly extends the lifespan of heating elements by ensuring they operate at optimal voltage, reducing wear compared to mechanical relays lacking this feature.

Design Excellence - 30 Amp Capacity: Evenheat carefully selects SSRs with a 30 amp rating but operates them at a cautious 15 amps, providing a significant safety margin for reliable performance. This practice ensures that SSRs remain well within their derating curve, promoting cooler operation and enhanced longevity, all upheld by Evenheat's commitment to quality.

Design Excellence - External SSR Heatsinks: Effective cooling is crucial for SSR longevity, and Evenheat addresses this by externally mounting SSR heatsinks. This improves airflow and prevents heat buildup inside the control enclosure. The design minimizes heat transfer between the control enclosure and the SSR, with standoffs creating a gap for cooling air. This meticulous approach guarantees that SSRs function at their optimal capacity, as demonstrated by an impressive six-year track record of zero failures.
