Danfoss 068U1037 Orifice Assembly

The Danfoss 068U1037 Orifice Assembly is a critical HVACR component engineered for high-precision refrigerant metering. This Type ORF #07 replacement orifice is specifically designed for integration with Danfoss TUA and TUAE thermostatic expansion valves, ensuring stable superheat control across a broad spectrum of operating conditions. By utilizing this genuine Danfoss 068U103700 assembly, technicians can maintain optimal evaporator efficiency in commercial refrigeration systems and air conditioning units. The assembly supports an extensive range of refrigerants, including R410A, R404A, R134a, and R22, with a rated capacity of 3.4 TR for R410A and 2 TR for R22. Constructed for durability in demanding environments, it operates reliably within a temperature range of -40°F to 50°F. This straightway design component is essential for contractors seeking to restore OEM-spec flow characteristics and prevent liquid slugging or hunting in TXV applications.

Key Benefits:

• Broad Refrigerant Compatibility: Field-ready for R448A, R449A, R452A, R32, and low GWP blends.
• Precision Metering: The #07 orifice size provides exact mass flow rates to prevent compressor floodback.
• OEM Reliability: Direct replacement for 068U1037 and 068U103700, ensuring zero-clearance fitment within TUA/TUAE valve bodies.
• Versatile Application: Suitable for both refrigeration and heat pump systems with operating temperatures down to -40°C.
• Compliance Standards: Meets EAC and LLC CDC TYSK approvals for regulated industrial and commercial use.

Common Questions:

Is the 068U1037 interchangeable with the 068U103700?
Yes, the Danfoss 068U1037 is functionally identical to the 10-digit 068U103700 part number often found in technical manuals.

Does this orifice assembly work with R410A systems?
Yes, the ORF #07 orifice is rated for R410A with an approximate capacity of 12 kW (3.4 TR), provided it is installed in a compatible TUAE stainless steel valve.

How do I ensure this is the correct orifice size for my system?
Verify the required tonnage and refrigerant type against the Danfoss capacity tables. The #07 provides 2 TR for R22 and 1.6 TR for R404A.
