More Accurate Calculations at the Design Stage
The updated calculator has been developed around the practical engineering requirements of OEM refrigeration equipment manufacturers. Engineers working in industrial chiller development and refrigeration system design often face time-consuming manual calculations at the project scoping stage — a step where inaccuracies compound quickly as system complexity grows.
The new functionality addresses this directly. Users can now calculate operating parameters for systems equipped with an economizer, model compressor performance under part-load conditions, and select equipment configurations with greater accuracy — all while significantly reducing the volume of manual engineering work required per project.
- Calculate operating parameters for systems with an economizer
- Model compressor performance under part-load conditions
- Select equipment more accurately with less manual calculation
- Analyze multiple refrigeration system operating scenarios in a single workflow
- Obtain reliable performance data earlier in the development cycle
These capabilities allow engineers to analyze different refrigeration system operating scenarios more efficiently and obtain more accurate performance data during the development of new projects. The updated calculator is already available in the OEM Partner Zone for all MIRAI INTEX partners.
Expanded Operating Envelope
Alongside the calculator update, MIRAI INTEX has significantly expanded the Operating Envelope map of the MIRAI propane turbocompressor. This gives engineers and system developers the ability to evaluate compressor performance across an even wider range of operating conditions.
A broader operating envelope translates directly into greater flexibility at the equipment selection stage. Developers can now assess suitability across more scenarios before committing to a configuration, reducing the risk of specification changes mid-project and helping to shorten overall development timelines.
MIRAI Propane Turbocompressor — Key Parameters
The compressor operates on R290 (propane), a natural refrigerant with a Global Warming Potential of 0.02 and zero Ozone Depletion Potential. Part-load operation spans 10% to 100% of rated capacity, with soft start and fast restart capability in under 55 seconds.
Key Advantages of the MIRAI Propane Turbocompressor
MIRAI INTEX is a global leader in the serial production of refrigeration equipment, delivering high-efficiency systems that eliminate harmful fluorinated gases entirely — making them completely safe for the environment. Founded in Switzerland in 2015 and now headquartered in Brno, Czech Republic, the company holds a leading position in air-cycle refrigeration technology and has spent over a decade transforming the ultra-low temperature cooling market.
The company's proprietary oil-free turbocompressor operates seamlessly across a wide load range — from 10% to 100% — delivering ultra-precise temperature control without relying on electric heaters for regulation. This means fewer components, higher reliability, and significantly lower energy consumption compared with conventional systems. MIRAI INTEX technology is trusted across pharmaceuticals, biomedical storage, plasma freezing, lyophilization, metal hardening, semiconductor production and testing, the food industry, climate chambers, gas liquefaction, and chemical cooling processes.

Chillventa 2026: New Model Debut
The next major milestone for MIRAI INTEX will be its participation in Chillventa 2026, taking place in October in Nuremberg, Germany. At the exhibition, MIRAI INTEX will present a new model of its propane turbocompressor, expanding the existing product range and opening additional possibilities for integrating the technology into industrial refrigeration systems.
From 13 to 15 October, visitors to the MIRAI INTEX stand (Hall 4, Stand 4-540) will be among the first to discover the new compressor, explore its operating characteristics, and discuss integration opportunities for modern refrigeration systems.
Dates: 13–15 October 2026 · Venue: Nuremberg, Germany · Stand: Hall 4, Stand 4-540. Visit the MIRAI INTEX stand to see the new propane turbocompressor model and discuss OEM integration options with the engineering team.
The MIRAI INTEX product line currently includes the MIRAI Turbo 290 (MT 290) and the MIRAI Turbo 350 (MT 350). The new model announced for Chillventa will extend this range, providing OEM manufacturers with additional options for system configurations requiring natural refrigerant solutions.
The expanded Operating Envelope and updated engineering calculator give OEM manufacturers more accuracy and flexibility at every stage of refrigeration system development. For engineers working to tighter project timelines with stricter environmental compliance requirements, these tools reduce calculation overhead and improve equipment selection confidence before development begins.
