Hi and thank you for your thoughtful question! Kaltra’s https://www.kaltra.com/microchannel-heat-exchangers microchannel heat exchangers are actually well-suited for use with natural refrigerants like ammonia and propane. Their designs are adaptable to a wide variety of fluids, which is key for anyone planning to future-proof their systems against changing environmental regulations. The reduced internal volume and high efficiency also mean less refrigerant is needed overall, which not only lowers environmental risk but can also lead to improved cost efficiency. Kaltra pays close attention to the requirements for using low-GWP and natural refrigerants, so you can be confident you’re making a choice that’s both forward-thinking and sustainable for the long term.
