How Does a Portable Water Chiller Work?

Several steps take place to complete the cooling cycle of a Portable Water Chiller. These steps are broken down for your easy understanding in this section.

  • The hot process fluid via the process valve reaches the pump reservoir.
  • The pump pulls water from the storage and sends it to the evaporator. This takes place by passing it through a flow switch and a filter.
  • The evaporator cools the fluid and returns it to the process via the tube and the process valve.
  • The refrigerant is vaporized and turned into a gaseous state by the evaporator. This is accompanied by heat removal from the process fluid.
  • The compressor compresses the low-pressure vaporized refrigerant. As a result, it is changed into high-temperature and high-pressure vapors sent to the receiver.
  • Municipal water or water tower removes heat from the vapor. As a result, the high-pressure vapor is converted into a high-pressure liquid.
  • The expansion valve (TXV) returns high-pressure liquid to the evaporator and converts it to low-temperature low-pressure liquid.

What are the Components of a Portable Water Chiller?

Different parts join together to form a well-functional Portable Water Chiller. Some of the main components are mentioned below, along with their purpose.


It comes with highly efficient solid-state interior motor protection. This is rubber-mounted, which helps in the reduction of vibration and noise.


During the condensation process, the vapors can cool to a liquid state. This takes place without difference in pressure, latent heat, or temperature.

Expansion Valve

It is necessary to lower the valve opening if the temperature at the evaporator’s outlet is extremely low.

It is necessary to increase its opening if the temperature is higher. This helps in controlling and maintaining the required evaporation temperature.

Filter Dryer

The refrigerant is filtered via molecular sieves desiccant to eliminate traces of moisture and impurities.

Using this filter means you won’t have to worry about it wearing out. This is because it comes with easy operation and indefinite life.

Liquid Line Solenoid Valve

A solenoid valve is installed at the filter dryer outlet. This valve prevents the liquid refrigerant from approaching the compressor when the system is shut down.


The fluid is cooled using a heat exchanger, either a tube in tube type or plate type. The evaporator generates turbulence to improve heat transfer. It is engineered to have a smaller pressure drop than other systems.


Stainless-steel impeller housing pump features high volume and high and low-pressure maintenance.

A mechanical seal is guaranteed to last for a long time and not leak. Overload is prevented by a safety feature provided by the pump motor.


When there is reduced heat transfer from a closed tank, FRP or stainless steel well-insulated tank conserves the energy.


All internal components are approachable for free maintenance. The weather-resistant paint coating is added to withstand tough environmental conditions.

What are the Benefits of a Portable Water Chiller for your Business?

There are a lot of benefits of using a Portable Water Chiller. Some of the most notable benefits you can get are written below:

  • Easy to maintain and repair
  • High flow efficiency and performance
  • Comes with compact efficiency
  • Convenient wash down due to rugged protection
  • Highly economical, reliable, and durable

What are the Process Flow Adjustments for your Portable Water Chiller?

A trouble-free and effective operation requires determining and setting the optimum water flow rate.

In the process loop, the pressure losses tell the water flow rate. More significant flow rates generally lead to more turbulent flow, resulting in low maintenance and better temperature control.

The evaporators are usually flow-sensitive; hence, operation efficiency depends on the liquid flow.

In order to achieve maximum Portable Water Chiller efficiency, the flow rate per ton of rated capacity should be around 2.4 GPM.

When the liquid flow is low, the efficiency is reduced. The evaporator might also be damaged in certain situations due to ice building.

The motor overload safety circuit will be tripped with an excessive liquid flow.

For adjusting process flow, follow these steps:

  • To start the process pump, turn it on.
  • Allow a few seconds for the system to be cleared of any air.
  • Look for a consistent reading on the digital coolant pressure gauge.
  • Perform flow tests on the unit to see if it is functioning correctly.
  • All process valves must be open if a low flow condition exists.

Portable Water Chiller Water Flow Switch

Portable Water Chiller Water Flow Switch

If the flow is low and all process valves are open, the following information should be considered:

  • The low refrigerant pressure limit switch might trigger due to low flow.
  • A flow bypass must be installed in the processing circuit to run at low flow. There is a chance that a portion of the flow will be redirected back to the Portable Water Chiller.
  • As a result, the overall flow remains higher than the limit.
  • A bypass may have been pre-installed on some models.

How to Adjust the Low Flow Bypass of your Portable Water Chiller?

Adjusting bypass valves is a critical step for the normal functioning of your Portable Water Chiller. It also helps maintain the flow and prevents the system unit.

  1. For Manual Low Flow Bypass Valves

In case of adjusting the low flow bypass valve manually, follow this guide:

  • Begin with the bypass valve, which is closed, and slowly open it.
  • Stop when the digital display shows that the low refrigerant pressure is in the desired operating range.
  1. For Automatic Low Flow Bypass Valves

In case of adjusting the low flow bypass valve automatically, follow this guide:

  • The top of the valve has an adjusting stem or a “T” handle.
  • When the stem or the “T” handle is turned clockwise, there is a reduction in bypass flow. It is because more pressure is applied to the valve’s spring.
  • The spring is relieved, and the counterclockwise bypass flow turns the adjusting stem and “T” handle.
  • Keep going until the digital low-pressure display reading for your Portable Water Chiller refrigerant is within the usual operating range. Now stop moving the adjustable stem or the “T” handle.
  • Lower the spring pressure to increase bypass if the digital lower pressure display reading is lower than average.

What are the Control Components of a Portable Water Chiller?

Various control components work together in providing smooth and easy control of your Portable Water Chiller. These components are:

  • Setpoint lockout jumper
  • Illuminated on/off switch
  • Probe calibration
  • Up and down arrow keys

What Does the Water System of your Portable Water Chiller Include?

The automated water makeup system constantly monitors the storage tank, which tops it off as needed. The structure of the water system involves the following steps:

  • Fluid pipes or appropriate hoses should be used for building the connection.
  • Build a link between the plant’s water supply and the water makeup.
  • Makeup water supply pressure should be no less than 20 psi at all times.
  • In the makeup water supply line, install a shutoff valve. Outside the unit, attach this valve.
  • For the sake of protecting your water from contamination, use a reverse-flowing prevention device. Use one that complies with the local codes.
  • When using glycol at temperatures below 48°F, do not use an automated water makeup mechanism.

How to Check the Refrigerant Charge of your Portable Water Chiller?

To the evaporator, the metering devices used are known as thermostatic expansion valves. This remains standard in all Portable Water Chiller models.

There also is a moisture detector in the sight glass installed in all models. Refrigerant charge should be checked when the system is running normally by taking the following steps:

  • Sight glass is covered by a plastic cap that must be removed.
  • Let system temperature and pressure settle by turning the system on.
  • No foam or bubbles should be seen in the sight glass when running the machine at 100% capacity. It should not be operated in the capacity control mode.
  • An experienced refrigeration technician should be called if any foam or bubbles are seen in it. It is because these bubbles are an indication of refrigerant loss.
  • The moisture indicator is represented by the “dot” in the center of the sight glass. At all times, it should be green.
  • Compressor life is shortened if the color is yellow or white, indicating that moisture has entered the system.
  • Replacement of the filter-drier should be done by a refrigeration professional.

What are the Optional Accessories for your Portable Water Chiller?

Different optional accessories available for your Portable Water Chiller are:

Low Flow Bypass Valve

If the process requires flow rates less than those specified in the design, you will need a low flow bypass valve.

Overhead Piping Kit

Installing an overhead piping kit can help keep the storage tank from overflowing when overhead piping is turned off.

In the “from process” line, a full line-size solenoid valve is interlocked with the pump. There is a check valve in the “to process” line (a valve that only moves in one direction).

Process Line Shut Off Valves

To and from process lines are connected via full-size ball valves at the unit exit. The flow rate of the process may be adjusted using these valves.

The flow rate can also be cut off to isolate the Portable Water Chiller.

E-Stop Button

The E-stop button is a mushroom-shaped button that, when pressed, stops all of the activities.

Fused or Non-Fused Disconnect Switch

An on-board disconnection button makes it easy to turn off the unit’s power supply.

Visual and or Audible Alarm

These alarms help in telling about the out-of-spec operation circumstances. Two different types of alarms exist:

Audible Alarm

A simple buzzer can trigger alarms.

Visual Alarm

An audible sound is emitted, and a beacon is flashed.

Reverse Flow Piping

For open-circuit operations, a reverse flow Portable Water Chiller is the best choice. The process functions as the reservoir keeping the flow circuit is nearly the same.

The water is returned to the pump suction under the action of gravity. Since the chiller lacks a reservoir, so external level control and water makeup are required.

What Type of Alarms is Present in a Portable Water Chiller?

When the controller detects an alarm, both the specified and displayed process variables alternately flash on display.

When a safe state is reached, these alarming problems should be solved. When a power-up situation exists, additional warnings are displayed, such as RST being flashed on the controller’s display.

The alarm stage is the last place where information is sent to the user. The “on” LED flashes whenever an alarm is triggered.

The controller has three sorts of alarms built-in, which are discussed below:

1-First Alarm Type

The first sort of alarm is a sort of annunciating cycling, and it’s the most common. However, the compressor will continue to run even if this alert is triggered.

This is followed by code flashing contrary to the process variable. These alarms are discussed below:


The change from the setpoint alert will turn on for a more extended period than allowed by the deviation temperature setting (dT).

This is when the time exceeds deviation temperature ignore time (dtt).


A warning alert will flash when the process temperature exceeds the alarm setting (htA).

2-Second Alarm Type

Before latching and needing a reset, the second annunciating type will follow three cycles in one hour. This sort of alert is the PAL low refrigerant pressure alarm.

The strobe and the bell will energize when the system is under low pressure. But when the pressure is restored, they will turn off.


When the lower refrigerant pressure switch detects a low pressure for an extended period, the (Pressure alert low) flashes (lpl), it will cycle thrice in an hour.

3-Third Alarm Type

Latching type alarms are the third type of alarm. The compressor is automatically cut off when this alarm goes off, and it must be individually reset when the problem is fixed.

This sort of alarm indicates excessive sensor and pressure failure. When the alarm is on, the following lights will flash:


Flashes after a power loss are restored.


The high-pressure refrigerant switch is illuminated with flashes. A manual reset of the high-pressure switch may be required to recognize this latching alarm.


It tells that the process temperature sensor is indicating range exceeding.


Indicating that the compressor has been turned off due to the process’s high temperatures, which might cause harm to the compressor (Hts)


When the low flow state continues for a more extended period than allowed, the flow alarms low light flashes, which must exceed the low flow of ignoring time.


As soon as the sensor for leaving water senses a temperature lower than the low-temperature alarm setpoint, the compressor is switched off (spl).

The compressor maintenance alarm serves as the final alarm. The run light flashes, but the display would not show that an alert has occurred.
