Access to industrial refrigeration net-zero cooling systems is well established, with many manufacturers offering products and training support across the globe but market share remains relatively low. Products featured include chillers and direct ammonia or CO2 systems. Recent developments reducing the charge size of ammonia systems are allaying safety concerns.
