The Danfoss Solenoid Coil is an essential electrical component that generates a magnetic field to control the operation of a solenoid valve. The coil consists of a copper winding around a core; when an electric current passes through, it creates a magnetic field that moves the valve plunger, allowing refrigerant flow to open or close as needed.
Danfoss coils are specifically designed for perfect compatibility with Danfoss solenoid valves—such as the EVR® series—ensuring smooth, efficient, and reliable operation in refrigeration and HVAC systems.
Key Features of the Danfoss Solenoid Coil
High Compatibility and Model Variety
Danfoss solenoid coils are designed to fit a wide range of Danfoss valves of different sizes and specifications, supporting diverse cooling and air-conditioning applications. They are available in multiple voltage options — both AC (24V, 115V, 230V, 400V) and DC (12V, 24V) — including dual-voltage / dual-frequency models for greater flexibility.
Durable and Robust Construction
Engineered to withstand demanding industrial environments, the coils feature strong housing materials resistant to vibration, humidity, and temperature fluctuations. Models such as Robust Coil and ToughCoil provide high ingress protection (IP67 / IP69K), making them ideal for harsh refrigeration applications.
Reliable Magnetic Performance
The coils provide consistent magnetic force to ensure precise valve operation, enabling accurate open/close control of refrigerant flow and enhancing overall system efficiency.
Easy Installation with Clip-On Design
Many Danfoss coil models use a Clip-On mounting system, allowing quick installation or replacement without tools. This reduces downtime and simplifies maintenance operations.
Benefits in Refrigeration Systems
Precise and Responsive Refrigerant Flow Control
Ensures fast and accurate valve actuation for critical refrigeration functions such as liquid injection, hot-gas bypass, or expansion control—maintaining optimal system temperature and pressure balance.
Improved Energy Efficiency
With precise refrigerant control, the cooling system operates efficiently according to load demand, minimizing overworking and reducing power consumption.
Protection Against Equipment Damage
Proper refrigerant management prevents liquid refrigerant return (liquid slugging) and other issues that could damage compressors or major components, improving long-term system reliability.
Enhanced Safety and Automation
The electrically operated design enables remote control or automated programming, improving system safety and minimizing human error in operation.
Simplified Maintenance and Reduced Downtime
The modular clip-on structure allows for quick coil replacement without disassembling the entire valve from the piping system—reducing maintenance time and costs.
