Chilled water precision air conditioning units for mission-critical applications with accurate thermal control and high energy efficiency.

Microchannel condensers are the most efficient air-to-refrigerant heat exchangers, offering heat transfer rates several times higher than those of traditional finned-tube coils. Their high efficiency, combined with other advantages—such as low airside pressure drops, reduced refrigerant charge, lighter weight, and smaller face areas—makes microchannel condensers an indisputable choice for modern HVAC and refrigeration systems.

Kaltra’s microchannel evaporators utilize advanced techniques to ensure uniform refrigerant distribution across microchannel tubes, effectively minimizing superheated regions. This results in optimal thermal performance across a wide range of operating conditions and loads, addressing key design challenges. With the capability of operating in reverse acting as condensers, our microchannel evaporators are ideally suited for air-source heat pumps.
