Nortek Global HVAC released Micro-Channel condenser coils in 2012. A year later, we launched indoor, Micro-Channel evaporator coils. Many Micro-Channel systems are easier to install due to their smaller footprint and lighter weight. AND, they use less refrigerant than other coils, making them easier on a contractors wallet and more eco-friendly.
The patented innovation of microchannel condensers incorporates vertical microchannel tubes to enhance condenser operation, avoid oil return issues, and ensure predictable coil performance. Unlike microchannel coils with horizontal tubes, the lower header serves as a mini-receiver to reduce critical refrigerant charge issues and provide easier system charging.
What You Need to Know About MicroChannel - HVAC SchoolFeb 19, 2018 · Microchannel is a coil type used in many evaporator and condenser coils. You can easily identify it by its flat tubes, and its fins appear as waves between the tubes. The technology was developed for use in the automotive industry and is used for radiators and automotive A/C condenser coils.
FEATURES AND ADVANTAGES. Microchannel coils present significant advantages over traditional finned tube coil design in every respect, including heat transfer efficiency, operating reliability, environmental safety, measurements, and cost:20% to 40% higher heat transfer
