The EP designation signifies enhanced espresso performance features including individual group temperature control, volumetric dosing with manual override, and the signature Slayer slow pre-infusion that has become a benchmark in specialty coffee. The 5-liter steam boiler delivers relentless steam power for high-volume milk drink service. Each group operates independently with dedicated PID-controlled brew boilers maintaining temperature within 0.1 degrees Celsius. The machine communicates with Slayer's cloud-based telemetry system for remote monitoring, shot logging, and maintenance scheduling. Custom powder coating in any RAL color allows cafes to match their branding precisely. The Steam EP represents Slayer's vision of what commercial espresso should be — uncompromising extraction quality with workflow efficiency that keeps baristas moving during peak service.
The Slayer Steam EP comes equipped with PID temperature control for precise brewing, pre-infusion for even extraction, pressure profiling for advanced shot manipulation, flow control for barista-level precision. It features a dual boiler boiler system made of copper with a 500 ml capacity. The rotary pump delivers 9.0 bars of pressure for optimal extraction.
Priced at $12,000, the Slayer Steam EP is designed for passionate enthusiasts and semi-commercial users who accept nothing but the best. As a semi-automatic machine, it gives you control over the brewing process while handling pressure and temperature automatically.
