Danfoss ORF Orifice Assembly | Multi-Refrigerant | 067B2771
Product Description:
The 067B2771 (Orifice No. 01) is the essential component for contractors in the UAE who need to match expansion valve capacity to smaller cooling loads precisely. In the diverse UAE market—from small laboratory chillers in Abu Dhabi to specialized beverage coolers in Dubai—this orifice offers the flexibility to handle multiple refrigerants. It is fully compatible with traditional gases like R22 and R404A, as well as the modern, lower-GWP alternatives such as R448A and R452A. Each assembly includes a high-quality filter screen that protects the valve’s internal seat from system contaminants, ensuring a longer service life and consistent performance in demanding Middle Eastern environments.
Key Features & Benefits:
- Extensive Refrigerant Support: Compatible with over 10 different refrigerants, making it an ideal stock item for UAE technicians servicing various cooling systems.
- Effective System Protection: The integrated filter screen captures debris and copper shavings, preventing valve blockage and ensuring smooth operation in UAE industrial zones.
- Interchangeable Flexibility: Allows for quick on-site capacity adjustments without the need to replace the entire valve body, reducing downtime for UAE businesses.
- Precision Metering: Optimized for smaller mass flow rates, ensuring accurate superheat control and energy-efficient evaporator operation.
- Robust Build Quality: Fabricated from premium materials to maintain consistent flow characteristics despite the intense heat and heavy-duty usage cycles in the UAE.
