Essential chiller maintenance checklist
/in Articles /by KALTRAEvery chiller or chiller plant should be, for the most part, relatively self-reliant. Yet like all heavy machinery, regular preventive maintenance can improve performance, prevent breakdowns, and extend the service life of the equipment. Chillers should be inspected leastwise two times a year if they are only used during the cooling seasons and four times a year in case of continuous operation.
We recommend the following procedures to keep your chiller system at peak performance and avoid unexpected shutdowns and costly downtimes. The below checklist has been compiled to help chiller plant operators conduct detailed and reliable maintenance on air-cooled and water-cooled chillers.

Microchannel heat exchangers: fabrication process
/in Articles /by KALTRAAir-conditioning and refrigeration industries have been evolving rapidly over the past decades. The latest energy efficiency regulations and phase-out of ozone-depleting refrigerants spur further development of air-to-refrigerant heat exchangers, making microchannel heat exchangers the better alternative to conventional heat exchangers for the majority of HVAC manufacturers. Heat transfer technology based on microchannel coils offers the largest potential for improving energy efficiency, reducing refrigerant volumes required, while also providing a number of other benefits.

Optimization of refrigerant distribution for microchannel evaporators
/in Articles /by KALTRAMicrochannel heat exchangers have been broadly used in automotive applications due to their advantages of compactness, low weight, and high efficiency. There are numerous heat exchangers designs based on microchannel technology with folded fins and flat tubes which are connected to manifolds. These designs are predominantly used for automotive radiators, condensers, and, more recently, automotive air conditioning evaporators.
