Package Units SM 1: Blue Anti-corrosion-fin and Coated Copper Tube Protects aluminum and copper pipes from toxic gases generated from foods, retards refrigerant leakage, and prolongs the cooling capacity. SM 2: Expansion Valve Allows safe storage of foods with a feature that self-adjusts the circulation of refrigerant as the internal temperature changes, thus recovering the required temperature fast. SM 3: Compressor Protected Solenoid Valve Decreases the inflow of refrigerant into the compressor when it is restarted after a stop. This extends compressor life and reduces compressor failure. SM 4: 18% Bigger Condenser than the Standard The condenser’s efficiency affects most of the refrigerator’s performance. Particularly, when used in a small compartment under high ambient temperatures or a dusty area, the package unit’s condenser needs to be bigger than standard ones in order to achieve the best performance. In consideration of the environments that our products may be subject to, condensers utilized in our products are 18% larger than competitors’. SM 5: Energy Efficient EC Motor Through the use of a highly efficient EC motors, our products reduce energy consumption and lower electricity costs, thus protecting the environment. Our products are designed with easy to replace motor and fan blades. SM 6: Highly Efficient Air Circulation Enclosure Designed to release hot air to the outside faster than competitors’ and to enhance the cooling efficiency. At the same time, it retards elevation of compressor temperature and keeps refrigerant pressure from increasing, thus saving energy as a result. * Hot gas condensate system is not included in outdoor units. Instead, a drain kit is installed.
