Costa Rica

Costa Rica’s approach to industrial refrigeration is shaped by its national sustainability agenda. Ammonia is widely used in food storage, agriculture, and beverage processing, where energy efficiency and safety are priorities. Regulations reference both local law and international codes, but implementation can vary by sector. With its strong environmental policies, Costa Rica is well positioned to expand the role of natural refrigerants under a structured regulatory framework.
