GEA Blu-Red Fusion – High-efficiency cooling and heating in one
The GEA Blu-Red Fusion combines high-performance cooling and heating in a single system. It integrates GEA Blu chillers (low stage) with GEA Red heat pumps (high stage), delivering extended capacity and temperature ranges for demanding industrial applications. CE-certified and equipped with advanced compressor models, it supports energy-efficient, future-ready operations.
Designed for applications with large temperature lifts, Blu-Red Fusion achieves best-in-class efficiency – especially where single-stage systems fall short. Typical uses include food, dairy, and beverage processing (e.g., hot water washdowns, pasteurization), as well as heating-only applications such as district or facility heating using low-grade heat sources like environmental water or wastewater. The system is based on GEA’s proven Blu and Red platforms and can be configured as a single unit for seamless integration.
Optimized for efficiency and sustainability
A high-efficiency ammonia-to-ammonia cascade heat exchanger connects the low and high stages without an intermediate liquid circuit. This minimizes pressure drop, system footprint, and refrigerant charge while reducing energy use and CO₂ emissions by double-digit percentages.
Operating modes for full flexibility
- Simultaneous cooling and heating (full or part load)
- Cooling only when no heating is required
- Heating regulation independent of cooling demand
- Option to be sized for lower, constant heating demand, avoiding oversizing and reducing overall costs
Key features and highlights
- Combined cooling and heating using ammonia (R717)
- Low energy consumption and reduced emissions
- Wide capacity range: cooling 205–1,810 kW; heating 275–2,400 kW
- Hot water up to 95 °C; cooling from –15 °C to +15 °C
- Stepless capacity control (VSD, slide valve, cylinder cut-off)
- Fully welded shell-and-plate heat exchanger
- Multiple plate material options for media compatibility
- Smart control with GEA Omni
