Service Tips

 
 During the fall and early spring months, when the temperatures are cooler in the morning and air conditioning is needed getting a water cooled chiller to operate can be tricky.  DB chillers require a differential between suction and discharge pressure to operate safely,  if the cooling tower water is too cool the chiller can experience an SDD alarm. An SDD alarm is an unsafe Suction discharge differential pressure, at least 30 PSI is required to move oil and lubricate the bearings of the compressor. To alleviate this it is recommended to install a condenser water 3 way by-pass valve, the valve can easily be installed in the piping close to the chiller. The logic of our microprocessor can drive the valve to operate so the correct SDD is maintained and our chiller can operate in any conditions. This option can be selected via the SPEC selection program.

TF WCFX-E 3 Compressor Chiller

Tip of the Month

 

 Redundancy is the key to designing a chilled water system. When using a dual or 3 compressor chiller, the design engineer can take into account the block loading. For example, if the total load of a new building is 1,000TR, if we provide (2) compressors per chiller with (2) chillers of 500TR each, in the event should a compressor fail there will still be 75% of full load available. If our competition uses a single centrifugal compressor, and they use (2) 500TR chillers and in the event of a failure then only 50% of the full load is available. For them to achieve 75% they would have to use (2) 750TR chillers. When designing a system with consulting engineers please drive in the point that redundancy is the key and a multiple screw compressor chiller is required.
