Air-cooled chillers · 3 – 25 kW · R513A
The FQBE series of liquid chillers represents the natural evolution of the historic QBE series, designed for high efficiency, reliability and sustainability in modern industrial applications.
Environmentally friendly R513A refrigerant for safe indoor installation
The FQBE series uses R513A refrigerant, a gas with a low GWP factor of 631, which is non-flammable and non-toxic, making it an environmentally responsible and safe solution.
Thanks to the use of R513A refrigerant, FQBE chillers can be safely installed indoors, meeting sustainability goals without compromising performance or safety.
Compact design and high energy efficiency
FQBE chillers feature compact dimensions, excellent energy efficiency and the use of advanced next-generation components. These characteristics make the series highly flexible and suitable for a wide range of industrial cooling processes, where limited space and energy consumption are key factors.
Standard configuration and main components
All standard FQBE models are equipped with carefully selected components that ensure efficiency, durability and ease of operation:
Robust construction and easy maintenance
The steel frame and panels are powder-coated, providing corrosion resistance and making the units suitable for use in industrial environments.
All fasteners are made of stainless or electro-galvanized steel, ensuring long-term mechanical reliability.
Removable panels provide easy access to internal components for routine maintenance and repairs. The clear component layout, together with the simple design of the refrigeration and hydraulic systems, enables intuitive operation and efficient servicing.
All models are equipped with lifting hooks, while FQBE008–025 models also feature lifting openings in the base, facilitating handling and installation.
