ECOOLERS – Marine Chillers for Sustainable, Future-Proof Cooling

Marine and offshore operators face a clear, immediate challenge: reduce greenhouse gas emissions and regulatory exposure while maintaining reliable, efficient cooling in harsh sea conditions and avoiding costly retrofits. Aeron ECOOLERS directly address that problem with the MWC 410-CO₂-5B, the world’s first DNV-certified marine water chiller that uses CO₂ (R744), a natural refrigerant with near-zero global warming potential (GWP = 1) and zero ozone depletion potential (ODP = 0). By replacing high-GWP HFC refrigerants, the system virtually eliminates direct refrigerant emissions and is not subject to F-gas restrictions, removing a major compliance and retrofit risk. The chiller’s advanced design automatically switches between transcritical and subcritical operation to preserve high COP across varying ambient and load conditions, and an optional heat-recovery module captures waste heat for additional energy savings. Safety and reliability are integral: CO₂ is classified ASHRAE A1 (non-toxic, non-flammable) and DNV certification verifies robust performance for marine environments. The practical value is twofold—significant reduction in refrigerant-related GHG exposure and a measurable impact on operating expense through improved efficiency and heat reuse—delivering sustainable, high-efficiency HVAC-R that future-proofs vessel cooling systems against tightening environmental regulations.
