Even after regular checkups and maintenance of chiller machines, they can face issues and degradation over the years due to the continuous workload or damages on different parts of the system. Whenever a client calls in to report an issue of the machine, the respective HVAC chiller services take an immense effort in reaching down to the customer and repairing it for better performance.

1. 3 Basic Problems of
Chiller Systems and their
Possible Causes

2. Even after regular checkups and
maintenance of chiller machines, they
can face issues and degradation over
the years due to the continuous
workload or damages on different
parts of the system.

3. Whenever a client calls in to report an issue
of the machine, the respective HVAC chiller
services take an immense effort in reaching
down to the customer and repairing it for
better performance. There are three basic
problems that are usually seen in chiller
machines and here are some of the most
possible reasons behind these failures.

4. CHILLER MACHINE DOES NOT
POWER ON
One of the most common causes of a
machine not turning on would be a
loose contact or an improper voltage
line that gets high and low at times,
whereas a chiller requires a constant
voltage source.

5. In cases of three-phase units, an
incorrect phase connection could
result in this problem.
There is a possibility of the circuit or
fuse to be blown or tripped that cuts
the current supply.
It could also be a simple mistake of
not noticing that the machine is in an
“off” position.

6. Constant fluctuations in the voltage
can result in this issue.The fluid stored
in the reservoir would be insufficient
for a powerful flow.
INSUFFICIENT FLUID FLOW

7. There is a high chance that the
process line, process valve, fluid
filter etc. are pinched or blocked
with dirt restricting the fluid flow.
This issue can also arise if the
process piping is too small when
the requirement is higher.
A failure of the pump.

8. Fluctuating voltage sources may cause
this issue of inadequate cooling.
The air filter or the condenser could be
clogged.The coolant fluid within the
machine could be unsuitable for
temperature requirements.
INSUFFICIENT COOLING EFFECT

9. Fluctuating voltage sources may cause
this issue of inadequate cooling.
The air filter or the condenser could be
clogged.The coolant fluid within the
machine could be unsuitable for
temperature requirements.
INSUFFICIENT COOLING EFFECT

10. The earlier heat transferring
properties of the coolant fluid
must have deteriorated over the
years.
There could be a refrigerant leak.
The evaporator could be filled
with ice.

11. These three are the most common problems
seen around chiller machines that trouble the
effective functioning of the system. The best
chiller repairing in UAE and other parts of the
world are definite in providing their qualified
services in repairing and fixing all the chiller
related problems for better functioning of the
machine in the future.
