 Hey  PK,
 
 Simply  Brilliant.  Is  the  system  running  smoothly?  How  expensive  is  the  Ti  coil  compared  with  Al  coil?
 
 Cheers
 
 Vince
 
 Mods,  this  is  gotta  be  a  Sticky.
 
 Edit:  Just  read  that  you  paid  9k  for  6m  Ti  coil.

 Vince,  so  far  so  good!!!  but  the  only  issue  is  that  when  the  chiller  is  off  the  tank  temp  goes  off  to  about  36C!!!  he  he  he...
 
 just  had  a  pump  failure  inbetween  but  that  was  rectified  and  system  is  operational  without  any  issues  currently  increased  the  operational  temp  to  26-27C...  and  great  going  no  issues
 
 yes  i  did  pay  that  much  for  the  Ti  Coil.  and  it  is  the  max  expensive  component  of  the  system,  but  it  is  worth  every  penny.  In  regular  chillers  the  Ti  used  is  only  2meters.

 Hi  PK,  your  innovative  DIY  chiller  is  truly  an  excellent  execution.
 My  tank  is  set  up  near  the  window.  The  Mumbai  summer  temperatures  peak  to  40C.My  tank  holds  about  265  litres  of  water,  which  is  a  lot  less  than  what  your  tank.  How  could  I  possibly  apply  your  innovation  for  my  tank?

 Surya,  sorry  for  the  delayed  reply...  you  can  use  a  DIY  canister  (like  mine),  have  the  Ti  coil  in  it  with  the  A/c  outdoor  unit  in  the  outside.  send  water  from  your  tank  into  the  canister  and  done  it  will  be..  for  your  tank  size  a  0.75  ton  outdoor  unit  will  be  sufficient.

 Natbox..  thanks  for  your  appreciation..  i  will  defenitely  write  an  article  on  this,  just  that  time  is  not  permitting  me  to  do  so..  
 
 as  for  your  information,  i  wanted  to  see  how  efficient/performance  oriented  my  chiller  is  compared  to  the  market  available  chiller  and  entered  into  an  expensive  proposition:   
 i  just  bought  a  Hailea  500A  (1/2hp)  chiller  rated  @  1200  litre  tank  for  my  tank  that  is  900  ltrs.  It  has  been  running  for  the  last  24  hrs..  the  start  up  temperature  was  29.6C  and  it  went  down  today  morning  to  28.6C  and  now  it  is  upto  29.6C...meaning  it  has  been  continuously  running  for  24  hrs  and  absolutely  it  is  unable  to  remove  the  heat  load  in  the  system  that  is  being  introduced  by  my  pumps  and  lights  (Actually  lights  are  off  most  of  the  time).  I  might  be  wrong  in  my  conclusion  if  there  is  no  coolant  in  the  chiller,  but  it  is  brand  new  one...  might  be  i  might  be  the  unlucky  guy  to  get  a  brand  new  chiller  without  GAS  in  it!!!  but  time  will  tell...
 
 whereas  my  chiller  was  working  perfecto!!!  just  that  i  needed  a  backup  chiller  just  in  case  my  DIY  chiller  conked  or  broke  due  to  some  reason..  hence  i  went  into  this  adventure..  and  found  that  my  chiller  works  far  better  than  anything  in  the  market!!!

 Mr.Sampathuuuu...  i  think  it  is  a  poor  mans  chiller  considering  the  fact  that  it  is  about  1/2  the  price  of  the  market  available  chiller  actually  of  lesser  rating..  whereas  if  you  are  looking  at  a  TECO  chiller  T60  i  think  the  pricing  of  a  1HP  is  nearly  1  lac...  so  defenitely  a  poor  man's  chiller  on  a  comparative  note
 
 Natbox,  i  think  the  chiller  is  unable  to  take  the  additional  load  that  is  being  put  into  the  water  by  the  motors.  i.e.,  the  rate  at  which  the  chiller  is  cooling  the  water  is  much  less  than  the  rate  at  which  the  motors  are  increasing  the  temperature  of  the  water..  and  this  is  exactly  the  same  principle  why  experts  say  DORM  fridge  wont  work  for  marine,  but  will  work  for  smaller  planted  tanks.
