MARS 03 Premium — Professional 3kg Coffee Roaster

Take control of your roasting with the MARS 03 Premium, a 3kg commercial coffee roaster designed for coffee shops, specialty roasters, and businesses looking to roast their own coffee in-house.

Built with a combination of manual controls and computer-based roasting profile management, the MARS 03 gives roasters the flexibility to develop, monitor, and reproduce roasting profiles using Artisan software.

Its Semi-Hot Air heating system uses a combination of 60% radiant heat and 40% hot air, providing a balanced approach to heat transfer during the roasting process.

Designed for Commercial Roasting

The MARS 03 has a 3kg per batch capacity, making it a practical choice for coffee businesses that need more roasting capacity than a small sample or home roaster while maintaining a relatively compact footprint.

A typical roasting cycle is specified at approximately 10–20 minutes, followed by a 3–5 minute cooling time.

Manual Control with Artisan Compatibility

The machine uses a manual control system, while allowing roasting profiles to be managed through a computer using Artisan software.

This allows roasters to:

• Monitor roasting data
• Record roasting sessions
• Store roasting profiles
• Manage and reproduce roasting records
• Develop more consistent roasting processes

The machine also features an automatic coffee discharge function that opens the discharge door when the set temperature is reached.

Semi-Hot Air Heating Technology

The MARS 03 uses Semi-Hot Air heating technology, consisting of:

60% Radiant Heat + 40% Hot Air

This heating configuration is one of the defining characteristics of the MARS 03 and is designed as part of the machine’s roasting system.
