MADDA and MASDA are hospital steam sterilizers built for central sterile services departments (CSSD). The range covers 15 models from 90 L to 845 L (1–12 STU), in single-door (MASDA) and double-door pass-through (MADDA) versions, with an EN 285 compliant sterilization system and a 316L stainless steel chamber. An integrated steam generator and HMI touch panel deliver reliable saturated-steam sterilization of heat- and moisture-resistant medical instruments.
Both series share the same chamber volumes and steam generators; the difference is the door design and the installation. Your CSSD layout decides.
8 models · 90–845 L
Loading and unloading happen in the same room. Suited to operating theatre preparation areas and compact sterile processing units.
7 models · 165–845 L
Mounted in the wall between the dirty and clean zones. Loads go in on the dirty side and come out on the sterile side, keeping the CSSD workflow one-directional.
Size your sterilizer by daily tray volume, container format (STU 300×300×600 mm or ISO 600×400×200 mm) and available installation space.

MASDA: single door, MADDA: double door (pass-through). All dimensions in millimetres.
Pressure, temperature, vacuum and door position are monitored throughout the cycle.
The optional water recovery system recycles vacuum pump process water through a closed-loop cooling circuit.
The sterilization system complies with EN 285; the unit is manufactured in an ISO 13485 certified facility.
From a compact 90 L unit to an 845 L system, the range fits healthcare facilities of every size.
Mixta plans the hospital steam sterilizer together with the whole CSSD. Washer-disinfectors, packing tables, sterilization baskets and sterile transfer units come from a single manufacturer in Ankara, Türkiye.
Our project planning and design team works with you on the CSSD layout across dirty, clean and sterile zones.
MASDA is single-door; MADDA is double-door (pass-through). Chamber volumes and steam generators are the same; the difference is the door design and the installation.
Single-door MASDA starts at 90 L and double-door MADDA at 165 L; both go up to 845 L, a capacity of 1–12 STU (300×300×600 mm).
Tabletop autoclaves are small clinical units (EN 13060). A hospital steam sterilizer is built for high-volume, continuous CSSD use; large steam sterilizers of 60 L and above fall under EN 285. For small volumes, see our tabletop autoclave.
When the CSSD separates dirty and clean zones with a wall. Loads enter on the dirty side and leave on the sterile side, so the workflow stays one-directional.
134 °C and 121 °C wrapped cycles, a 134 °C fast cycle, a heavy surgical instrument cycle, Bowie-Dick test, automatic leak test and custom material programs.
Optimized vacuum and steam algorithms plus the optional water recovery system cut water consumption by up to 30%.
