Kaltra - Aluminium Microchannel Condensers

Innovative heat transfer technology

The patented innovation of microchannel condensers incorporates vertical microchannel tubes to enhance condenser operation, avoid oil return issues, and ensure predictable coil performance. Unlike any other microchannel coils, 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, dry coolers and rooftop systems.

Advanced microchannel condensers significantly improve HVAC systems performance. The benefits include:

• Up to 40% higher efficiency compared to fin/tube designs

• Lower airside pressure drop

• Closer approach temperatures

• Up to 20% smaller coil face and thin design

• Less weight (up to 50%)

• Less refrigerant charge (typically 40% to 60%)
