For jobs where steam alone isn’t quite enough, the Evo 304 Detergent adds a genuine chemical cleaning capability on top of everything the Evo Blu already offers. It’s Tecnovap’s most capable Evo-series unit, built around the same stainless steel AISI 304 boiler and unlimited steam autonomy via automatic water refilling, but running at a higher 8 bar operating pressure and reaching a genuine 174°C — noticeably hotter than the Evo Blu’s 165°C.

What sets this model apart is its detergent injection system, delivered through a separate 1-litre tank alongside the standard 3-litre water reservoir. Rather than relying on heat alone to break down grease and grime, operators can inject detergent directly into the steam stream at temperatures between 90°C and 160°C — a genuinely useful capability for stubborn, greasy build-up that steam by itself would take longer to shift. Everything is managed through the same electric control panel found across the range, displaying live operating pressure and steam temperature so operators always know exactly what the machine is doing.
