Regulation of temperature is essential in industrial as well as commercial areas. Likewise, laboratories also require efficient chilling systems for the right cooling processes.

A Laboratory Chiller helps take the heat out from one place and transfer this heat into the ambient air or any other system.

A Laboratory Chiller is compressor-based equipment used in not just cooling but also adjusting the temperature of the liquid.

The filter present in the Laboratory Chiller prevents the contact of the machine with harmful substances.

You can adjust the temperature, pressure, and flow of your Laboratory Chiller according to your choice.

There are various benefits of using Laboratory Chiller over other cooling systems, which are discussed in this guide.

This guide will present you with plentiful information in knowing all about the Laboratory Chiller.

What is Laboratory Chiller?

A Laboratory Chiller is a machine used for extracting excess heat from a liquid. This can happen based on vapor compression or vapor absorption.

Now, the liquid passes through a heat exchanger for cooling the air or the appliance as per your need.

As a result, waste heat is produced by the Laboratory Chiller. Now, it is essential to restore this heat for heating purposes or to release the heat into the ambient air.

The major role of a Laboratory Chiller is to take heat from one source and pass this heat to the water or ambient air.

Laboratory Chiller offers a major role in various applications essential in a lab. These include MRI scanning; blood cooling, CT scanning, Radio therapies, Laser systems, and many more.

Laboratory Chiller Flow Switch

How Does Laboratory Chiller Work?

Laboratory Chiller converts heat from one object to another, typically by the use of a liquid.

It is a system that extracts heat from a liquid through a vapor-compression or absorption refrigeration cycle.

This liquid in the Laboratory Chiller will then be pumped through a heat exchanger to cool machinery or a certain process stream (like air or process water).

Refrigeration: To start chilling, the Laboratory Chiller must first be refrigerated.

The heat produced by the equipment is transferred through this refrigeration process, which lowers the temperature of a Laboratory Chiller.

Evaporation: As the cooling process begins, the heat is dissipated using either water or air (depending on whether you’re using a water-cooled or air-cooled Laboratory Chiller).

The water or air will bubble and turn into a vapor as a result of this evaporation.

Compression: As the vapor is produced, it is passed through a compressor, which raises the temperature and pressure.

Condensation: The vapor then travels from the compressor to a condenser, which reduces the temperature and converts the vapor down to a liquid.

When a liquid form is reached again, it is metered into the evaporator, and the loop begins again.

What is the Importance of Laboratory Chiller for your Application?

Laboratory Chiller performs a variety of important functions in laboratories and provides several benefits. Continue reading to learn more about the role of Laboratory Chiller.

• Enhanced accuracy

One of the key reasons Laboratory Chiller is so critical is that the Laboratory Chiller will help ensure the precision of an experiment or test.

If there is even one degree of difference in environmental conditions such as temperature, test findings may be skewed.

Laboratory Chiller plays a critical role in ensuring that trials and measurements can be performed in the proper environment while maintaining precise temperatures.

• Improved sustainability of labs

When using cool water to chill samples, a large amount of tap water is needed, which can be incredibly wasteful. Laboratory Chiller helps labs become more effective by offering an alternative to this inefficient activity.

Moreover, it is becoming more important to own as laboratories grow more aware of their water use and how inefficient activities adversely affect the environment.

• Cost savings

The cost savings provided by Laboratory Chiller is one of the key reasons for being a valuable piece of lab equipment.

Laboratory Chiller will conserve tens of thousands of gallons of water per week by eliminating the need for large amounts of fresh water to cool samples.

This equates to a significant amount of money. As a result, using it will result in a very fast return on investment as well as long-term savings.

• Increased convenience

Laboratory Chiller has a consistent and dependable supply of liquid coolant, unlike other conventional cooling systems such as water, dry ice, liquid nitrogen, and ice, which can be inconvenient to use.

As a result, Laboratory Chiller has unrivaled comfort, which is critical in busy laboratories.

• Improved safety

Laboratory Chiller is essential for the protection of lab workers. If chemicals or other substances used in an experiment are not kept at specific temperatures, they can react differently.

It is important to use it to regulate the temperature of an experiment to preserve the safety and health of scientists to avoid unintended and potentially harmful reactions.

Easy to Move Portable Laboratory Chiller

 How to Maintain Your Laboratory Chiller?

Laboratory Chiller will need a variety of forms of servicing overtime to maintain the equipment running smoothly.

• Keep Tubes Clean for Optimal Heat Transfer

Both Laboratory Chiller tube systems will need cleaning regularly to keep them operating at peak performance.

Tubes can accumulate pollutants over time, reducing performance dramatically, but cleaning would avoid this.

• Treat Condenser Water to Prevent Scale and Chiller Corrosion

Water treatment would be needed for condensers that use open cooling sources such as atmospheric cooling towers to avoid corrosion and biological growth that could damage the system.

As a result, it will use less electricity, which means it will consume less power.

• Analyze the Compressor Oil

Compressor oil should be tested for moisture content, acids, and other toxins that affect the output of Laboratory Chiller on an annual basis.

• Lower Incoming Water Temperature

You can improve the performance of Laboratory Chiller much further by lowering the temperature of the incoming water.

• Keeping an Eye on the maintenance of Laboratory Chiller

Operating logs are one of the most important things in the maintenance of a Laboratory Chiller. The log tracks data related to equipment operation. The technicians and operators use log data to evaluate performance.

After viewing the statistics and data, you can spot a slowly developing performance trend that might go and notice in daily operations.

Technicians also can use log data to diagnose specific Laboratory Chiller problems. To be the most effective tough operator, it must enter at least once daily, and someone must review the data regularly.

Information in the log varies by Laboratory Chiller. A piece of minimum information should include time, date, drive motor current, and voltage.

Also, the information should include immediate drive motor current and voltage supply and return temperature of condenser water supply.

It should also contain the return temperature of the chilled water evaporator and condenser pressure and the oil temperature and pressure.

Technicians also need to record any maintenance they have performed.

A scheduled inspection is also essential for proper maintenance, depending on the component technician inspects during the procedure.

Typically this can take place or daily, weekly, monthly and will provide various benefits. A large Centrifugal Chiller is scheduled for inspection once per year.

However, the types of chiller you are using require different frequencies of maintenance and inspection.

In general, instructions require only a few minutes to complete and don’t interfere with the operation.

However, in other cases, such as tube inspection, your Laboratory Chiller must be shut down to undergo the inspection procedure.

In both cases, inspections are designed to maintain efficiency and identify minor problems so the technician can correct them before they become more destructive for the Laboratory Chiller.

Technician Evaluating Laboratory Chiller Performance by Using Log Data

 How to Choose the Right Laboratory Chiller for your Application?

The size of a Laboratory Chiller is determined by the amount of heat it can extract per unit of time, which is determined by the application’s heat characteristics.

Calculating the appropriate size may seem difficult, but it is very easy if you know the formula and a few other details.

The Laboratory Chiller expert technician, on the other hand, will be happy to help and will also do all of the measurements necessary to properly scale the Laboratory Chiller for your precise operation.

The size of a Laboratory Chiller you need can be determined using a simple formula. However, there are a few things you should be aware of before getting started:

• The temperature of the incoming water
• The temperature of the water needed
• The flow rate

The four basic factors that determine Laboratory Chiller sizing and selection are discussed below in detail.

1. 1. The temperature of the coolant that you want to use.

This is the temperature of the coolant at the process or equipment’s inlet. It is critical to take temperature readings at this point to account for coolant heating as it passes from the Laboratory Chiller to the process.

The higher the potential heat gain, the longer the distance to be covered. By insulating the cooling line and placing the Laboratory Chiller as near as possible to the equipment or process to be cooled, this heat gain can be reduced.

2. The amount of heat produced. 

This is the total amount of heat to be removed. BTU/hour or watts are the most common units of measurement.

The Laboratory Chiller manufacturer will often have the heat load value. If not, the following formula can be used to measure it:

Heat load = Flow rate x Fluid density x Fluid specific heat x Constant x ∆T°

If the Laboratory Chiller will be working at ambient temperatures above 68°F (20°C), at high altitudes, or if the heat output of the system is variable, and it is problematic.

Here it is normally recommended that a safety factor of 20 to 50 percent be applied to the measured heat load to provide a safety factor.

This will also include a safety net for potential cooling requirements.

However, avoid the urge to add more safety factors to your Laboratory Chiller than is required.

An oversized Laboratory Chiller will not cool your equipment more efficiently, but it will cost more to buy and run.

3. Coolant temperature and flow. 

These parameters are usually given by the equipment manufacturer and are based on the process/material being cooler’s surface area and heat transfer characteristics.

Your Laboratory Chiller must produce coolant at the correct flow rate and pressure. If the flow rate or pressure is too high, the cooling equipment will be damaged.

And if it is too low, heat removal will be insufficient.

Your Laboratory Chiller supplier will assist you in determining the best form and size of the coolant pump for your needs.

4. 4. Heat dissipation in the condenser.

How the heat extracted will be dissipated is the final factor that influences chiller/heat exchanger selection.

Air-cooled condensers discharge heat into the ambient air, requiring only electricity and airflow to operate. Heat is transferred to the facility’s cooling water supply by devices with water-cooled condensers.

There is also a type of Laboratory Chiller present with remote condensers (i.e., the condenser is located outside the facility).

Such a Laboratory Chiller is quieter; it takes up less room, and does not generate heat inside the house, lowering summer cooling costs.

Such Laboratory Chiller, however, is more expensive to build and difficult to relocate.

Other considerations, such as heating capacity, remote temperature monitoring, DI water capability, and so on all influence how a Laboratory Chiller is designed in the end.

When assisting you in selecting the best Laboratory Chiller for your specific application, conscientious Laboratory Chiller vendors will take all of these factors into account.

 How to Troubleshoot your Laboratory Chiller Problems?

There are a variety of problems that a Laboratory Chiller can encounter over time, all of which will require maintenance, replacements, or new parts.

• Low-Pressure Trip

Low refrigerant temperatures, a split capillary in a power assembly, little or no water movement, clogged screens or filters, or mud or antifreeze covering the evaporator tubes may cause low-pressure trips.

• High-Pressure Trip

When water-cooled condensers have little or no discharge, when water-cooled condensers have mineral accumulation from poor-quality water, it causes high-pressure trips.

Also when air-cooled condensers are clogged with debris or have a nonfunctioning fan, or when the chilled water tank temperature is excessively high at over 80 degrees Fahrenheit, high-pressure trips occur.

• Oil Failure Trip

Low oil due to refrigerant leakage, low superheat, or damage to oil pumps may cause oil failure trips.

• Blown Fuses or Starter Trips

When an engine, compressor, or wire shorts is over-amped, it may trigger starter trips and blown fuses.

The Laboratory Chiller is operating, but it is not reaching the set temperature in this case.

When an evaporator has built-up ice inside, an antifreeze failure causes poor heat exchange or the load exceeds the capability of your Laboratory Chiller.

Laboratory Chiller Blown Fuse Troubleshooting

How to Increase the Efficiency of Laboratory Chiller?

Contaminants in a Laboratory Chiller refrigerant circuit can reduce its operating efficiency.

A Laboratory Chiller is more susceptible to contaminants because any leak allows air and moisture to enter the system.

To reduce the effect of contaminants, manufacturers initially add a purge system that separates air and moisture from refrigerants.

The system works but is not very efficient and did not remove all the contaminants in a Laboratory Chiller. Moreover, the use of purged system resulted in the loss of refrigerant.

Now, high-efficiency part systems are both efficient and very much effective.

Besides removing most air and moisture from the refrigerant in a Laboratory Chiller, it operates without allowing refrigerant to escape. As a result, the refrigerant particularly gets free of contaminants.

High-efficiency part systems are available on the new Laboratory Chiller or the manager can use them for the existing Laboratory Chiller.

In both cases, technicians should regularly monitor the unit’s runtime because any changes in the operation can indicate a developing leak.

Another exciting feature that helped Laboratory Chiller in energy efficiency is exceptional heat transfer to surfaces.

For proper functioning of your Laboratory Chiller, these grounds must be clean and unrestricted of buildups such as sludge breakdown and scale.

Even a narrow layer on the surface can mean decreased efficiency of your Laboratory Chiller.

A technician should clear the condenser tube yearly to keep the coverings clean.

Evaporator tubes need to be rinsed only every three years, so because they operate in a sealed system, while mechanics can often use brushes for the clearing of a Laboratory Chiller.

Else, a poorly folded system might call for the use of any additional chemical.
