| 1. EKCO2 Series |
 |
NH3/CO2 brine unit
Refrigerant: NH3 Brine: CO2
CO2 brine temperature: -5℃ to -40℃
Uses: Freezing, refrigeration, low-temperature air-conditioning, showcase cooling, freezer cooling, etc.
Features:
1) Uses non-fluorocarbon NH3 as the primary refrigerant and CO2 as the brine.
2) Offers a 10% efficiency improvement over existing systems (Mayekawa data).
3) Requires no control of brine concentration or PH and the absence of corrosion reduces maintenance cost concerns.

NH3/CO2 dual unit
Refrigerant: High side: NH3; Low side: CO2
CO2 evaporation temperature: -40℃ to -55℃
Uses: Freezers, ultra-low temperature warehouses, vacuum freezing systems
Features:
1) Uses non-fluorocarbon NH3 for the high side and CO2 for the low side.
2) Offers a 30% efficiency improvement over existing systems (Mayekawa data).
3) The high efficiency of this unit is achieved through use of a proprietary CO2 high-pressure freezer unit.
