Ammonia screw compressor for industrial refrigeration
Experience high-efficiency cooling with reduced leakage risk using modern ammonia screw compressors, ideal for enhancing your industrial refrigeration systems.

The GEA CompaX series, offered by GEA Heating & Refrigeration Technologies, is a suite of semi-hermetic ammonia screw compressors designed for high-efficiency cooling applications. These compressors are exceptional for minimizing leakage risks and offering robust performance in ammonia refrigeration systems.
Operating with a shaft-seal-free design, the GEA CompaX ensures minimal vibration and noise, making it suitable for installations near populated areas. This line handles a flow volume of up to 372 m³/h at speeds up to 6,000 rpm, accommodating small to large capacity requirements. The dynamic variable internal volume ratio and wide speed range optimize energy use, reducing overall operating costs.
Particularly suited for the food, beverage, and pharmaceutical industries, these compressors are integral to processes in frozen food production, such as Danish pastries and frozen bakery goods. They facilitate precise temperature management, essential for maintaining product quality.
The GEA CompaX series also simplifies systems integration with its compact and cost-efficient design, reducing installation footprint. It uses the natural refrigerant ammonia in compliance with the 2015 F-gas regulation, providing an environmentally friendly solution. With decades of screw compressor expertise, GEA offers a reliable, low-maintenance option for industrial refrigeration challenges.
