AIREF Standered CHILLERS are designed and fabricated as per good engineering practice. However for special requirement, chillers can be designed and manufactured. Multiple refrigerant circuits and pass arrangement permit a wide range of chiller application. Removable refrigerant heads permit easy access to tubes for routine inspection. Baffle spacing are selected to produce the most efficient heat transfer for all water flow rates. Suitable for Refrigerant -12, 22,500&502.  
RANGE : 5TR to 120TR.
SHELL : Standard ERW pipes / shells rolled from quality steel plates.
TUBES   : Plain Copper tubes (20 / 21 gauge) are expanded into tubes sheets holes.  
TUBE SHEET : Steel plants with adequate thickness for strength and proper expansion of tubes.  
HEAD : Steel fabricated heats are provided with multipass arrangement on refrigerant side.  
REFRIGERANT CONNECTIONS   : Inlet and outlet connections are provided (socket / pipe).  
FINISH : After proper cleaning Chillers are painted with two coats red-oxide.
PRESSURE TESTING   : Chillers are tested for 17 kg/ Pneumatic on tube side and 17kg/ Hydraulic pressure on shell side.
