The 9-321-44-1 horizontal evaporator coil, manufactured by 3R, is a crucial component of a refrigeration or air conditioning system. This evaporator coil is designed for horizontal installation, making it an excellent choice for applications where space is limited in the vertical direction.
Measuring 30 inches in length, this evaporator coil is well-suited for medium-sized systems. Its width is standard at 14 inches, and its height is 21 inches when installed, including the thickness of the insulation.
The 9-321-44-1 evaporator coil is engineered with copper tubing and aluminum fins. Copper is a preferred material for coils due to its excellent thermal conductivity, ensuring efficient heat transfer. Aluminum fins, on the other hand, offer high surface area for heat dissipation and are lightweight, making the coil easier to install and maintain.
This horizontal coil features a low-pressure drop design, which ensures a consistent airflow through the system. It also includes a factory-installed drain pan, making installation more convenient. The coil is designed to operate with a refrigerant charge of R-134a.
The 3R 9-321-44-1 horizontal evaporator coil is engineered for durability. It features a corrosion-resistant coating on the aluminum fins and a protective coating on the copper tubing. This coating not only enhances the coil's resistance to corrosion but also reduces the need for frequent maintenance.
Installation of the 9-321-44-1 horizontal evaporator coil is straightforward. It comes with pre-drilled mounting holes and can be installed using the provided mounting hardware. The coil also includes factory-installed insulation, making it ready for use right out of the box.
In summary, the 9-321-44-1 horizontal evaporator coil by 3R is a reliable and efficient component for refrigeration and air conditioning systems. Its copper tubing and aluminum fins ensure effective heat transfer, while its low-pressure drop design promotes consistent airflow. The coating on the aluminum fins and copper tubing enhances its durability, making it a long-lasting investment for your system.
