Cold Chain

Cold Storage Solution

Cold storage refrigeration solutions for food processing, pharma and chemical cold chains — cascade CO2 units running at −38 °C nominal with the small NH3 charges that keep plant floors safe.

The constraint we design for

Deep cold, small refrigerant inventory

Cold storage and food processing plants push refrigeration toward lower temperatures — and stricter safety and environmental rules. MOON-TECH’s answer is the AIST NH3/CO2 cascade: NH3 stays in the high-temperature circuit at a small 110–220 kg charge, while CO2 — zero ozone depletion, zero greenhouse forcing — carries the −38 °C evaporating duty.

Food processing plants

The AIST series is widely used in cryogenic refrigeration in food processing, at home and abroad, with 271–526 kW modular capacity steps.

Safe on the plant floor

Skid-mounted in a container housing with no refrigeration control room, micro-pressure-drop small-charge condenser, and an integrated active defense system with real-time monitoring, alarm and spray device.

  • Frequency conversion start and run — no impulse current, significant energy-saving advantage
  • High system automation — less manual commissioning time, lower operating cost
  • Higher cooling capacity per unit volume of CO2 and higher heat transfer efficiency

The rest of the cold chain

Pharma & chemical cold duty

Low-temperature process cooling for pharmaceutical and chemical applications, including dangerous operating areas.

Natural refrigerant policy

NH3 micro-filling chiller units and CO2 systems align your plant with HCFC substitution direction — MOON-TECH has run phases of the national HCFC substitution demonstration project.

Energy closed-loop

Pair cooling with steam booster heat pumps: the heat you reject is upgraded back into high-grade saturated steam for the process.
