Refra specializes in designing and manufacturing both transcritical and subcritical CO2 refrigeration systems, backed by over 10 years of expertise. These systems are custom-made to meet the specific needs of each customer, ensuring high-quality, reliable performance. Transcritical solutions provide efficient low and medium-temperature cooling, with options for integrated booster systems and heat recovery for additional heating applications. Subcritical systems excel in cold storage and industrial cooling, particularly in cooler climates, offering significant energy savings. Refra also delivers cascade systems combining CO2 and propylene refrigerants for outstanding efficiency in warmer regions, ensuring versatile and sustainable refrigeration solutions for diverse industries.

Refra’s standard Galaxy series of air-cooled chillers represents a comprehensive solution for the cooling needs of industrial and commercial buildings. Designed to accommodate a wide range of power demands, Galaxy chillers offer cooling capacities from 45 kW to 465 kW, making them suitable for various applications, from small office buildings and supermarkets to large factories and distribution centers.

All Galaxy chillers come standard with propane (R290) refrigerant, which has a low global warming potential (GWP) and contributes to lower energy consumption. With over a decade of experience in producing refrigeration equipment with Propane and CO2, Refra actively promotes the use of natural refrigerants as part of its commitment to reducing the environmental impact of industrial processes.

A key feature of the Galaxy series is its adaptability, achieved through a modular assembly system that allows for easy integration of additional options, such as built-in hydraulic modules and heat recovery systems. This flexibility ensures that each chiller can be customized to meet specific operational requirements, providing a tailored solution for any cooling challenge. The range covers different power needs, making it an ideal choice for environments with varying demand levels, whether they require a smaller-scale solution or a high-capacity system.

Galaxy chillers are engineered with a strong focus on reliability and operational continuity. Depending on the model, the chillers are equipped with one to four independent cooling circuits. This design ensures that even in the event of a circuit failure, the remaining circuits can continue to operate, maintaining cooling performance and minimizing downtime. This redundancy is particularly valuable in critical applications where uninterrupted operation is essential.

Constructed with high-quality materials and advanced technology, Galaxy chillers are built to perform in the most demanding environments. These Chillers feature a robust galvanized steel frame with a durable powder coating and effective insulation, providing both protection and noise reduction. For applications where noise is a concern, the option to add 50 mm of rock wool insulation further enhances the quiet operation of these units. The integration of microchannel heat exchangers, reciprocating compressors, and EC fan motor technology ensures high efficiency and long-term reliability.

What sets Galaxy series apart is its user-friendly design, rooted in Refra’s commitment to a plug-and-play ideology. This approach simplifies installation and operation, allowing customers to quickly deploy their cooling systems with minimal effort. The ease of use, combined with the chiller's adaptability and reliable performance, makes the Galaxy series an excellent investment for customers seeking efficient, long-lasting, and customizable cooling solutions.

Refra’s reversible Propane Heat Pump line delivers a versatile and high-performance solution for heating and cooling across a broad spectrum of commercial and industrial applications. The product line ranges from compact models suitable for smaller commercial settings to robust units designed for large industrial facilities, covering heating capacities from 20 kW to 550 kW and cooling capacities from 20 kW to 480 kW.

At the core of this product line is the use of R290 refrigerant, a natural refrigerant known for its low global warming potential (GWP). This choice reflects Refra’s commitment to environmental sustainability, providing customers with an eco-friendly option that also enhances energy efficiency and lowers energy consumption.

Refra heat pumps are designed with full-inverter technology, which optimizes energy use and enhances overall performance. This technology allows the units to adjust their output based on current demand, leading to significant energy savings and improved operational efficiency.

The construction of these heat pumps emphasizes durability and performance. They feature a compact frame made from galvanized steel with powder coating for added protection and longevity. The design includes high-quality components such as EC fan motors, finned tube heat exchangers, and reciprocating compressors. For enhanced performance in challenging conditions, the units incorporate features like water drain outlets and electric heating cables for defrosting. Some models offer additional rock wool insulation for quieter operation, catering to environments where noise reduction is crucial.

The heat pumps are also designed with operational safety in mind. Many models come with multiple independent circuits, ensuring continuous operation even if one circuit fails. This redundancy is especially valuable in critical applications where uninterrupted heating or cooling is essential.

Refra’s propane reversible heat pump line combines advanced technology, environmental responsibility, and robust construction to offer reliable and efficient solutions for a wide range of heating and cooling needs.
