Liquid/liquid heat exchanger

microchannel

NNOVATIVE HEAT TRANSFER TECHNOLOGY Our range of microchannel condensers comprises models with horizontally- or vertically-oriented multiport tubes, in single or multiple pass design, suitable for use with various refrigerants. In addition to a wide span of dimensions, the customer may choose from various combinations of multiport tubes, fin types and fin pitches, connections, mountings, and protective coatings. 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. An integral baffle assures proper coil operation and liquid refrigerant return. Compared to finned tube condenser designs, our microchannel condensers are a robust design with major technical benefits. With proven field experience, we offer many competitive advantages for OEM equipment and new applications. Equipment designs incorporating advanced microchannel condensers span a wide range of systems designs, including air-cooled chillers, heat pumps, condensers, and rooftop systems. FEATURES AND ADVANTAGES Microchannel condensers have a number of advantages over traditional finned tube designs that significantly improve HVAC systems’ performance: Up to 40% higher heat transfer efficiency Lower airside pressure drops Closer approach temperatures Up to 20% smaller coil face area Less weight – up to 50% Less refrigerant charge: typically 40% to 60%
