Since mechanical relays are prone to failure over time, this relay access port becomes especially valuable when replacement is necessary. 

(Of course, the recommended option is to bypass the mechanical relays for the long-lasting Quiet Drive Solid State Relay system. Read the next tab to understand why this is the right choice.)

Full Stainless Steel Jackets

Multi-section, multi-jacketed kilns were originally designed with the dual purpose of reducing production costs for kiln manufacturers and simplifying installation for the end user. While these objectives are commendable, they often result in compromised kiln quality, a compromise that Evenheat is not willing to make.

Evenheat prioritizes top-notch quality in its kilns. That's why they construct their kilns with full stainless jackets that extend from the top to the bottom. These full stainless jackets ensure rock-solid, long-lasting construction. With full stainless jackets, you can trust that there will be no leaks, no shifting, and no structural weaknesses. When it comes to true build quality, insist on Full Stainless Jackets.

Fed up with the frequent issues and expensive upkeep commonly linked to mechanical relays? It's time to make an upgrade.

Introducing the revolutionary Quiet Drive Solid State Relay System by Evenheat, a technological marvel that stands apart for its complete absence of mechanical components, promising enduring and maintenance-free operation. Immerse yourself in its exceptional performance, delivering precise and controlled heating that consistently produces superior results.

Unpacking the World of Relays: Solid-state relays (SSRs) emerge as a robust and dependable alternative to the conventional mechanical relays, those reliant on moving metal contacts and electromagnets. SSRs embrace a solid semiconductor block, entirely devoid of moving parts, eradicating physical wear and ushering in a new era of temperature control in kilns.

Advantage 1 - Uninterrupted Operation: SSRs boast unparalleled longevity. Unlike their mechanical counterparts, they operate without the wear and sparking commonly associated with mechanical relays. Bid farewell to the familiar clicking sounds in a kiln, signaling mechanical relay operation, which inevitably leads to wear and costly repairs. In contrast, Evenheat's SSRs operate silently and reliably, offering durability that aligns with the life expectancy of your kiln or oven.

Advantage 2 - Precision in Temperature Control: Mechanical relays are bound by limits in cycling frequency, balancing control effectiveness and relay lifespan, typically cycling every 10 to 14 seconds. SSRs, on the other hand, achieve a staggering cycling rate of up to 120 times per second, allowing for rapid adjustments and unparalleled temperature accuracy. Every Evenheat control, including the now-standard Icon controller that supersedes the previous Set-Pro, harnesses the rapid cycling of SSRs to ensure extraordinary temperature precision.

Advantage 3 - Prolonged Life for Heating Elements: Solid-state relays employ Zero Crossing technology, ensuring precise switching on and off at the zero-voltage point within AC power cycles. This innovation significantly extends the lifespan of heating elements, as they operate at the ideal voltage, minimizing wear compared to mechanical relays lacking this precision.

Design Excellence - 30 Amp Capacity: Evenheat thoughtfully selects SSRs rated for 30 amps, yet operates them conservatively at 15 amps, creating a substantial safety margin for consistent and dependable performance. This practice ensures SSRs function comfortably within their derating curve, even when handling a 15-amp load, fostering cool operation and extended longevity. It's a testament to Evenheat's dedication to superior design.

Design Excellence - External SSR Heatsinks: Effective cooling proves indispensable for SSR longevity. Evenheat addresses this by externally mounting the SSR heatsinks, promoting airflow and mitigating heat buildup within the control enclosure. This design effectively isolates heat transfer between the control enclosure and the SSRs, reinforced by standoffs creating an air gap for cooling. This intentional design choice underpins optimal SSR operation, underscored by an impressive track record boasting zero failures over six years.
