Retail chains in many countries are reviewing their carbon footprint and are focusing on refrigeration systems, particularly on choosing non-HFC, environment-friendly gases. While transiting to lower GWP refrigerants, among which flammable and mildly flammable gases like propane and HFOs, refrigerant quantity and, correspondingly, gas circuit volumes become essential factors in systems’ design.
High global warming potential refrigerants for refrigeration systems are being phased out because they are one of the culprits of climate change, while, at the same time, nearly 50 alternative refrigerants are classified as environment-safe.
Due to the high and constantly growing market demand for compact microchannel coils, Kaltra expands its manufacturing capabilities of serpentine heat exchangers by installing new tube bending machines and assembly lines equipped with semi-automatic core builders, fin mills and fin inserting machines.
Propane (R290) is a naturally occurring hydrocarbon used successfully in industrial refrigeration for many years received attention from designers, contractors, operators, and retailers to reduce greenhouse emissions. An indication of the increasing acceptance of propane is its adoption by many key customers from large supermarket and shopping mall chains to franchise food stores and minimarts at gas stations throughout the world. The latest trend in this market segment is adopting microchannel heat exchangers – condensers and evaporators.
Kaltra offers the latest heat transfer technology for electronics cooling, cooling of laser devices, medical appliances, and other small cooling applications with serpentine heat exchangers based on microchannel technology.
