Compact reciprocating heat pumps for high efficiency heating
The GEA RedGenium is a compact, energy-efficient heat pump designed for small- to medium-capacity industrial heating. Based on the successful GEA BluGenium chiller concept, this series is highly adaptable, low in ammonia charge, and arrives fully piped, wired, and ready for installation.
At the core of the range is the GEA Grasso V XHP series, delivering supply temperatures up to 95 °C – the only standard reciprocating heat pump on the market to achieve this level. For mid-range requirements, the GEA Grasso V HP (up to 70 °C) and Grasso 5HP (up to 80 °C) models offer cost-effective, high-efficiency solutions.
The RedGenium is ideal for process heat in industrial operations and integration into district heating networks. It can draw heat from diverse sources – Including wastewater and groundwater – or utilize an optional cascade evaporator to recover waste heat directly from existing refrigeration systems.
