Sanden is way much better than DENSO:
Now let me explain you guys some details of why DENSO or Sanden are rated better:
- There is no temperature issue as a brother above said. Both compressors can work on high temperatures
- In any car (esp. 1000cc) compressor size really matters alot.
- Not only does a compressor play an important part in cooling, but evaporator and condenser also play a very important role. (internal freezing unit : condenser)
Now in Pakistan, especially in alto 1000cc the internal freezing unit is very small. Now if you just get that changed with a japanese alto unit, i swear man itni aalaaa cooling ho jati hai k u wont believe it.
I have had a sanden unit in my alto for 3 years.
A. it never failed
B. Only once i got the compressor seal re-done
C. It was described by alot of alto driving people as the best chilled AC experience they had in a 1000cc Alto.
So if you want to enjoy a low-cost compressor, just give it the right thing...
P.S remember, do-not use large sized compressors for MEHRAN because it already has a very congested engine place for cooling and may cause over-heat issues.
But for large cars, don't use small compressors cause they are low-priced.
