The AlumaTuff™ evaporator coil is a matched system of all-aluminum coils, composed of aluminum tubes, tube sheets, and plate fins. According to the manufacturer, all-aluminum coils prevent formicary corrosion, rusty tube sheets, and help avoid pinhole leaks. The coil still uses copper-to-copper refrigerant line connections so that standard installation procedures can be followed. They are available for different cabinet widths and are designed for a flush fit and easy attachment with upflow, downflow, and horizontal left airflow. According to the company, refrigerant charging or evacuation is made easy and quick with an external service port, along with a nonbleed thermostatic expansion valve for refrigerant replacement without brazing. Features include a two-way, sloped noncorrosive drain pan, easy access to the internal components, and foil-faced insulation. The coil is backed by a 10-year limited warranty.
