LEO-CHILL PACKAGED DA SERIES OXYGEN PLANT CHILLERS
LEO-CHILL PACKAGED DA SERIES OXYGEN PLANT CHILLERS
- LEO-CHILL range of DA Series Chillers is the latest version of packaged chillers designed and tailored to specifically meet Oxygen & Nitrogen manufacturing Industries.
- LEO-CHILL range of DA Series Chillers has been engineered to offer Many Features in a Compact, Space constraint design.
- DA Series Chillers range is built with advance Dependable Controls, which give optimum performance under variable operating conditions.
- The DA Series Refrigeration unit has 2 specially designed evaporators, which are tested at 70 kg pressure.
- Evaporator 1 is for 1st stage where air from compressor enters into the evaporator at 22°C and is reduced to 10°C, and is moisture free.
- Evaporator 2 is for 2nd stage where air from drier enters into the evaporator 2,And the temperature is reduced from 15 to 16°C to 7°C, and subsequently entersthe Molecular Sieve Column for further process.
- Complete Electrical and refrigeration protection and to ensure Precise process Fluid Temperatures a Microprocessor based Controller is standard in all DA Series range of Chillers.
- All Wiring and Refrigeration circuits are Colour Coded for quick and simple servicing.
- Well-designed, easy to operate, In built Control Panel incorporating fuses, Switchgears, Terminal connectors with full function control. Micro processor temperature Controller Gauges with protection HP/LP switch (Alco), Expansion through High quality Dual Danfoss Expansion valve, LED display for fault detection.
- The DA Series are also available for larger oxygen production systems viz, 400, 500, 600, 1200.
