Danfoss is a leading global manufacturer of refrigeration components and systems, offering a comprehensive range of innovative, reliable, and efficient products. Its offering is designed to meet the needs of commercial, industrial, and sustainable refrigeration systems, with a focus on energy efficiency and environmental protection.

1. Refrigeration Compressors

• Reciprocating compressors: Hermetic and semi-hermetic, suitable for a wide range of traditional and low environmental impact refrigerants, with powers from 0.2 to over 20 kW.

• Scroll compressors: The MLZ and LLZ series, ideal for medium and low temperatures, ensure efficiency, silence and reliability.

• Turbocor® centrifugal compressors: Oil-free, equipped with magnetic bearings and variable-speed permanent magnet motors, guarantee energy savings of between 30% and 50%.

2. Unità Condensatrici Optyma™

Compact and versatile condensing units for commercial applications, such as refrigerated cabinets and cold rooms, are optimized for A1 and A2L class refrigerants. They offer high performance, easy installation, and low noise.

3. Thermostatic Expansion Valves (TXV)

Danfoss expansion valves are essential for efficiently managing the refrigerant flow within the evaporator, ensuring precise superheat control.

• Available in various capacities and configurations to suit any refrigeration system, from small commercial units to complex industrial plants.

• The thermostatic bulb measures the suction line temperature to regulate the refrigerant flow in real time.

• Compatible with traditional refrigerants (R134a, R404A, R407C, R410A) and natural refrigerants (CO₂).

• Electronic versions (EEXV) available for more precise and dynamic control, with integrated electronic regulation, ideal for systems with variable needs or advanced energy management systems.

4. Refrigeration Filters

Danfoss offers a wide range of filters for the protection and maintenance of refrigeration systems:

• Filter Driers: Effectively remove moisture, acids and contaminants from the system, protecting components from corrosion and damage.

• Mesh filters: They retain solid impurities and metal particles present in the circuit.

• Filtri olio: Specific for keeping the compressor's lubricating oil clean, ensuring performance and durability.

• Materials and designs resistant to high pressures and temperatures.

• Available for all major refrigerants, with versions also suitable for natural refrigerants and new low-GWP blends.

• Some models are equipped with service valves and clogging indicators to facilitate maintenance and diagnosis of the system.

5. Electronic Regulators and Controls

• Electronic controllers to optimize the operation of compressors, fans, valves and defrost systems.

• Control systems with advanced connectivity, remote monitoring and integrated diagnostics.

• Software and apps (e.g. Coolselector®, KoolConnect) to support the design, configuration and maintenance of systems.

6. CO₂ Refrigeration Solutions

Danfoss is a leading supplier of components and systems for transcritical and subcritical systems using CO₂, a natural and sustainable refrigerant with low environmental impact.

• Valves and compressors specifically designed for the unique characteristics of CO₂.

• Smart Store systems for supermarkets and food retail, integrating energy efficiency and connectivity.

7. Accessories and Complementary Components

• Pressure switches, temperature sensors, safety valves, fittings and pipes.

• Communication modules for integration into Building Management Systems (BMS).

• Diagnostic and maintenance tools.
