A Laboratory chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. After that liquid can be flowed through a heat exchanger for air cooling or other equipment. Cooling creates heat waste that must be released to the environment or, for better efficiency, recovered for heating purposes. Concerns in design and selection of chillers include performance, efficiency, maintenance, and product life cycle environmental impact.
The benefits of chillers
The benefits of the chiller are many:
-Energy Savings
- Works in a large space
- Suitable for the environment
- Long shelf life
- Suitable for a wide range of places in the industry
-Retains moisture in the air
What is the cooling temperature?
Chillers (cooling systems) come in a variety of different temperatures. Each chiller is suitable for a different type of work. Therefore it is important to choose the right chiller for you. The temperature is determined by the coolant used. The temperature will usually be up to 20 degrees.
Application of Laboratory chillers
The use of chillers is very diverse in the field of industry and laboratory. Chillers can be found in: Cooling rotary evaporators, reactors, furnaces, flanges, laser machines, CNC machines,controlled cooling of products,chemical processing, pharmaceutical formulation, food and beverage processing,hospitals and more.
In different laboratories it is necessary to cool water for chilling samples.:
Analytical Instruments:
Used to cool high-performance liquid chromatography (HPLC) systems, mass spectrometers, and other analytical instruments.
Medical Equipment:
Chillers are crucial for medical imaging equipment, such as MRI machines, where temperature control is vital for accurate readings.
Industrial Processes:
Many industrial processes, including chemical reactions, semiconductor manufacturing, and laser systems, require precise temperature control provided by laboratory chillers.
Principle of operation of laboratory chillers
Removing heat from one object to another using a liquid.Basically a machine that removes heat from a liquid through a cooling cycle of steam or absorption.
Key Features:
Temperature Range:
Laboratory chillers come with different temperature ranges to accommodate various applications. Some can reach extremely low temperatures for applications like cryogenics.
Coolant Compatibility:
Ensure that the chiller is compatible with the type of coolant required for your specific application. Common coolants include water, ethylene glycol, or a mixture of both.
Cooling Capacity:
The cooling capacity is the amount of heat the chiller can remove per unit of time. It is crucial to match the cooling capacity with the heat load of your application.
Temperature Control Accuracy:
Precision is essential in laboratory settings. Look for chillers that offer accurate temperature control to meet the requirements of your experiments or processes.
Safety Features:
Laboratory chillers should include safety features such as temperature alarms, pressure controls, and automatic shutdown in case of malfunctions.
How to know what size a chiller needs?
It all depends on the amount of heat the chiller can remove in a period of time.Consider the amount of water entering, water temperature required, flow rate
What are Recirculating Chillers
These are compact, portable units that circulate a coolant through the system to absorb heat from the equipment or process being cooled.
Ideal for small to medium-sized applications where precise temperature control is necessary.
