Cooled Condenser Cleaning    

 

The  Haskris  R1600  chiller  includes  two  air-cooled  condensers  which  draw  a 
substantial amount of air across the condenser fins and coil.  As dust and debris 
collect,  heat  transfer  becomes  less  efficient,  resulting  in  the  loss  of  cooling 
capacity.    To  remove  the  accumulation  of  debris,  vacuum  the  condenser  fins 
thoroughly during regular services. Additional cleaning may be required in some 
extreme environments. Nearby vegetation, such as cotton wood trees, etc. should 
be avoided or removed if found to be problematic. A brush may be used to loosen 
compacted  debris  being  careful  not  to  damage  the  fins  or  the  condenser  coil 
coating.    HASKRIS  DOES  NOT  RECOMMEND  THE  USE  OF  A  PRESSURE 
WASHER AS THIS MAY DAMAGE THE FINS OR CONDENSER COIL COATING.

Finding the Pressure Setting of the Bypass Valve    

To  find  the  pressure  setting  of  the  bypass  valve,  restrict  the  flow  water  from  the 
Haskris  R1600  chiller  by  closing  the  Supply  Side  Isolation  Valve  (Figure  2.9).

CHILLER IS IN OPERATION.  

CHILLER IS IN OPERATION.  

CHILLER IS IN OPERATION.  The pressure gauge will then indicate the valve set-
point.  As noted above, the valve does not snap open and shut.  It will crack open 
approximately 16-18 psi (1.1-1.2 Bar) below its set-point, depending on the valve.  
The  valve  continues  to  open  gradually,  increasing  the  amount  of  bypass,  as 
pressure approaches the valve set-point.  When the set-point is reached, all of the 
flow from the pump is being bypassed.  For this reason, the valve should be set a 
minimum 20 psi (1.4 Bar) above the normal operating pressure to ensure full flow 
of the pump through the closed loop.
