Danfoss

Danfoss is a Danish international company regarded as a world leader in energy-efficient solutions for refrigeration, heating, drive technology, industrial automation, and hydraulic systems. With over 85 years of experience and operations in more than 100 countries, Danfoss delivers products and systems that reduce energy consumption, increase productivity, and support sustainable infrastructure.

The Danfoss range is broad: VACON NX and VLT series frequency inverters (0.37 to 22,000 kW) for energy-efficient motor control, EX and MSG series refrigeration control valves for cooling systems and heat pumps, AVTA and AVPQ thermostats for heating systems, hydraulic pumps and motors (Danfoss Power Solutions), BITZER and Turbocor turbo compressors, and an extensive line of thermostatic fittings for building installations.

Danfoss VLT frequency inverters are particularly popular in the pump and fan industry: by dynamically adapting motor speed to actual demand, VLT drives typically save 30-60% energy compared to uncontrolled motors. Integrated HVAC functions (sleep mode, bypass, PID flow control) greatly simplify installation in air handling systems.

Danfoss Power Solutions (formerly Sauer-Danfoss) supplies hydraulic open and closed-circuit piston pumps (Series 42, 45, 90), hydraulic motors, proportional valves, and electronic control systems for mobile hydraulics in heavy off-road vehicles, agricultural machines, and industrial applications.

At Verkopershulp.nl we carry over 2,511 genuine Danfoss parts, including frequency inverter modules, refrigeration control valves, thermostats, hydraulic components, and control modules. As an authorized distributor we guarantee fast delivery and technical advice.

History

Danfoss was founded in 1933 by Mads Clausen in Nordborg, Denmark. The company began producing thermostat valves for refrigeration systems. This product laid the foundation for Danfoss' long-term focus on energy-efficient solutions for cooling and heating systems. In the 1950s Danfoss expanded into heating control components and became a European leader in hydraulic heating systems. From the 1960s to the 1980s Danfoss diversified into industrial electronic drive technology with the introduction of its first frequency inverters. The acquisition of Sauer Inc. in 2000 (hydraulic transmissions for mobile machines) was a milestone that transformed Danfoss into a broad industrial group encompassing hydraulics, electronics, and refrigeration technology. Today Danfoss has approximately 40,000 employees and annual revenues exceeding €10 billion. Following the acquisition of Eaton's hydraulic division in 2021, Danfoss Power Solutions is one of the largest providers of hydraulic systems for mobile machines worldwide. The company is investing heavily in decarbonization solutions, green hydrogen, and energy transition technologies.

Frequently Asked Questions

How do I select the correct Danfoss VLT frequency inverter?
Select the VLT based on motor power (kW), supply voltage (200-240V or 380-480V or higher), application type (pump/fan = VLT AQUA Drive, general = VLT AutomationDrive, crane/hoist = VLT Crane Drive), and required IP protection rating. Consider overload capacity (150% for 60s for standard, 160-200% for heavy-duty) and ambient temperature.
Are Danfoss VLT drives EMC certified for use near sensitive measurement equipment?
Yes, Danfoss VLT drives are CE certified and comply with EMC directive 2014/30/EU. For installations with high EMC requirements, built-in EMC filters are available (Cat. C2 or C3). Use screened motor cables and correctly tighten EMC clamps for minimal emission. In sensitive installations an additional output filter (sine filter or DU/DT filter) may be necessary.
How do I configure the PID controller in a Danfoss VLT drive for pump applications?
Activate the PID controller via parameter P20-00 (Closed Loop) and set the setpoint (desired pressure or flow). Connect the feedback signal (4-20mA pressure sensor) to the analog input. Configure P20-21 (proportional gain), P20-22 (integration time), and P20-23 (differentiation time). Use Danfoss MCT10 configuration software for easy parameterization and monitoring.
Which Danfoss refrigeration control valve should I use for HFC refrigerants?
Danfoss offers TUA, TUAE, and TEAT expansion valves for HFC refrigerants such as R134a, R404A, and R410A. The TEAT series provides electronic expansion valve functionality for optimal energy efficiency. Ensure the valve capacity (kW) matches your cooling system and that the valve construction is compatible with your refrigerant and operating conditions.
Are Danfoss hydraulic pumps suitable for use with synthetic oil?
Danfoss Series 42, 45, and 90 hydraulic pumps are designed for mineral hydraulic oil ISO VG 32-68. Use of biodegradable and synthetic oil is possible but requires verification with the Danfoss compatibility guide, as some seal materials and coatings are not resistant to all synthetic fluid types.
How do I program a Danfoss VACON NX drive via fieldbus?
VACON NX drives support PROFIBUS DP, PROFINET, EtherNet/IP, Modbus RTU/TCP, CANopen, and DeviceNet via optional fieldbus boards. Configure fieldbus parameters (station address, baud rate) via the local operator panel. Load GSD/EDS files into your PLC engineering software (TIA Portal, Step 7, etc.) for automatic parameter mapping and diagnostics.
Does Verkopershulp.nl supply Danfoss thermostatic valves for district heating?
Yes, we supply Danfoss RA, RAS-C, and RTD-N thermostatic valves and thermostatic heads for district heating and underfloor heating systems. These are available in M30x1.5 and Danfoss RA connections. We also supply electronic radiator thermostats (Danfoss Eco, Living Connect) for smart temperature control. Delivery within 1-2 working days for common models.
What is the difference between Danfoss EEV and TXV expansion valves?
A Thermostatic Expansion Valve (TXV) uses mechanical pressure and temperature feedback from the evaporator outlet for control – simple, reliable but limited in precision. An Electronic Expansion Valve (EEV) uses a stepper motor and electronic control for more precise modulation, faster response, and optimal refrigerant distribution at variable loads. EEV provides 5-15% higher energy efficiency at part load.
