Why are Condenser Coil Better Than Traditional Condensers?

condenser coil

Microchannel Condenser Coil is widely used as they provide high performance. They are significantly used in various applications. The traditional heat exchangers are less capable than it. By reducing thermal resistance and system size, there is an increase in the efficiency of the system level. It is widely used in radiators and automotive Condenser Coil.

The coils are made of aluminum and are mostly used because of superior heat transfer due to increased surface area. 

This technique differs significantly from the traditional copper-aluminum condenser and is more than reliable; nearly it’s a standard in the automotive industry. The microchannel condenser is constructed entirely of aluminum, and the fins are put between the two successive tubes and fixed. These fins are procured from a single-channeled aluminum sheet. 

Along the tubes, a variable number of channels can have different geometry. Compared to the tubes utilized in copper-aluminum coils, the internal sections of these channels are incredibly narrow. 

Advantages of Condenser Coil

The condenser coil is generally more efficient than its copper-aluminum counterparts of the same size due to these characteristics, enabling an efficient heat exchange between the condensing fluid and the battery channels. 

The main advantage of a microchannel battery is its low volume which means less refrigerant inside the condenser.

However, conventional condensers are 30% to 50% of the total refrigerant mass of the machine, the microchannel condensers decrease the whole mass of the refrigerant and its respective price. Microchannel condensers greatly enhance the performance of HVAC systems compared to conventional finned tube designs.

  • An increase in heat transmission efficiency drops lower airside pressure

Another important advantage of microchannel heat exchangers over conventional HVAC coil designs is their low airside resistance. The similar size microchannel heat exchanger has a 60 percent less airside pressure drop than a 6-row finned tube heat exchanger of the same size and capacity. Thus, it lowers the fan power consumption and noise level generated by the fans 

  • The coil face area is reduced 

Aluminum microchannel heat exchangers have gained much popularity in the automotive industry due to their lightweight, small size, and low internal volume. These qualities are essential in the cooling systems industry, particularly when it comes to mobile cooling systems. Their reduced size and weight relate not only to the cheaper transport and handling costs but also to the lowered employment cost.

  • Resistant to corrosion

The corrosion potential of the all-aluminum microchannel coils is substantially lower than that of multi-metal coils as there are no dissimilar metals. As a result, microchannel coils are fundamentally a superior option for installations near the ocean, in polluted areas, or in any other situation where corrosion might be a problem. Compared to manually brazed heat exchangers, microchannel coils only need one braze operation in a controlled environment, lowering the possibility of leaks.

  • Protective coating 

The multi-metal finned tube coils are more susceptible to galvanic corrosion than aluminum microchannel coils. So installing multi-metal finned tube coils may require a high level of protection. We advise employing microchannel heat exchangers in petrochemical facilities, adiabatic systems, installations in extremely contaminated areas, or maritime atmospheres to ensure long service life.

Car radiator all essential guide you should know

car radiator

What is a radiator in a car?

Most people are not aware of the importance of radiators. The car radiator is the vital component that is responsible for cooling vehicles. Its function is to monitor the temperature of the vehicle and prevent it from overheating.

Components of radiator 

  • The core
  • The pressure cap
  • Outlet Inlet tanks
  • Radiator hoses

The core is the important part that allows hot coolant to flow through the engine releasing its heat and the radiator cools it for the next trip around the heat exchange.

The pressure cap ensures the cooling system remains pressurized by sealing it. The coolant is pressurized in the radiator and prevents it from boiling. In this way, it helps the system to become more efficient.

The inlet and outlet tanks are located in the rotator head where the coolant flows in and out of the radiator. The inlet tank allows the hot liquid to flow from the engine and when it is cooled goes out through the outlet tank and then back to the engine.

Radiator hoses help the coolant move through the engine. It is important for connecting the inlet and outlet tanks to the radiator and engine. The water pump and the thermostat are other important cooling system parts that work alongside your radiator. 

The temperature of the engine is regulated by the thermostat. The thermostat will let more coolant in if the engine requires cooling. If the engine is at the right working temperature, then it won’t let off the coolant.

The coolant is forced through the system by the water pump. The engine drive belt typically turns on the pump, which then spins the pump’s blades to push liquid through the system as needed. The coolant is kept inside gaskets and seals. Coolant is also important as it prevents the engine from overheating. This also helps to lubricate the different parts.

Check the car radiator if it has an issue

  • Check if the coolant leaks

Sometimes when you park the vehicle and if you notice low coolant levels then there must be a crack in your radiator. This leaking of coolant can be easily seen on the ground.

  • Discolored coolant

The coolant is green and yellow and is thin in consistency. Rust can change the color of the radiator and it becomes dark and rusty in color and becomes thick and consistent. This prevents the engine from cooling.

  • Overheating of car radiator

A vehicle may be heated again and again, the car radiator can be the reason for it since it is the way by which engine heat is removed.

  • Damaged fins

Due to damaged fins, the airflow is blocked to the radiator. The fins are generally damaged due to too much pressure while cleaning them.

Why do we?

We have built a good reputation amongst clients and have eight years of experience. Our team members continuously contribute to the company’s development and help clients in all possible ways. If you are looking for high-quality car radiators, you should consult the experts at Narain cooling. Buy car radiators from trustworthy manufacturers.


Radiators are an essential part of any engine system. Moreover, a car radiator is important for the engine to work efficiently. India is the main industry for car radiators and it is a more vital component of an engine than any of its components. Due to regular use, the engines of vehicles generally tend to warm up. Additionally, radiators prevent overheating of vehicles by relieving the engine of excess heat. We are the best car radiators manufacturer and provide quality radiators to their clients.

Finned Tube Heat Exchanger An Brief Overview

Finned Tube Heat Exchanger

In this hot summer, we are sitting in a chilled room. Have you ever thought about how it is possible? That is because of heat exchangers. Heat exchanger applications are not only in domestic appliances but also in crucial industrial manufacturing sectors. They transfer heat between hot and cold streams to save energy. A heat exchanger with fins attached to the outer tube is known as a Finned Tube Heat Exchanger. In these heat exchangers, fins increase the surface area for heat transfer, which increases the rate of heat exchange.

What are Finned Tube Heat Exchangers?

Finned tube heat exchangers are the type of heat exchangers in which fins are attached to the outer tube of the exchanger. Adding fins facilitates the transfer of fluid outside the tube. It is for the transfer of air or another gas. 

In a finned tube heat exchanger, an overall flow pattern is often crossflow, but it can also be counterflow or parallel flow.

A finned tube is very helpful as one of the fluids is air or any other gas in an air heat exchanger. There is a low air-side heat transfer coefficient, which increases the surface area of heat transfer.


Why Finned Tube Heat Exchangers are made of Aluminum?

  • Aluminum is a lightweight metal than heavier metals like stainless steel or copper. In the case of radiators, the lightweight material improves the performance of the equipment.
  • Aluminum is a great heat conductor, making it an excellent choice for radiators. While comparing to other materials, aluminum radiators heat efficiently and quickly reach the necessary temperature.
  • It is a recyclable metal. So by buying aluminum radiators or fin tubes, you are getting an eco-friendly product.

Working Principle Of Finned Tube Heat Exchangers

In a finned tube heat exchanger, fins are outside the tubes. The liquid will flow through the finned tube with air or another gas flowing outside, increasing the heat transfer rate due to the greater heat transfer surface area.

The fins on a crossflow tube exchanger are usually circular or square radial fins. Fins should be longitudinal rather than radial in a counterflow or can be parallel flow fin tube exchangers. In an enclosed heat exchanger, finned tubes work as internal tubes. 

Uses Of Finned Tube Heat Exchanger

  • Finned tube heat exchangers are helpful in the condition where the heat transfer coefficient inside the fluid is higher than the fluid outside the tube. 
  • Other finned tube air heat exchangers include automobile radiators. The truck radiator‘s job is to cool the hot water in the tubes by circulating air through them in a crossflow pattern. Also, the objective of the air conditioner evaporator coil is to condense the air traveling through it.
  • Finned tube heat exchangers are helpful in the chemical industry, petrochemical industry, automobile (heavy truck radiators, car radiators) industry, etc.
  • Recent developments have seen dry cooling for steam power plants grow rapidly. In this method, an air-cooled condenser replaces a water-cooled condenser.
  • For different purposes, the shapes and sizes of fins are unique, like- S-shaped fins to increase the surface area for heat exchange in heavy truck radiators to increase the heat transfer rate. Therefore, these are the best truck radiators in use nowadays.

Microchannel Condenser And Their 3 Types You Should Know

Microchannel Condenser

What is a Microchannel Condenser?

In layman’s terms, a  microchannel condenser is a device that cools the temperature down. It is an object that tries to the condenser, to convert the state of a gas or a vapour into liquid. Also, it releases a concealed form of heat that plays a role in the conversion of states without changing the temperature. 

Where Is The Microchannel Condenser Coil Used?

These Condensers are used in various industries, objects and places – gas pipelines, boilers, air conditioners, chemical industries, steam power plants, chemical processes- distillation, Rankine cycle, etc.

Who Are The Manufacturers of Microchannel Condensers?

There are various manufacturers that produce condensers. Narain Cooling, one of the best manufacturers of condensers, produces them with a 100% guarantee of good quality. 

Types of Microchannel Condensers Coils

There are three main types of Condensers that are categorized on the basis of an external object they use as an agent to carry forward the process.

  • Air-Cooled – As the name suggests, this type of condenser uses air to release the heat present inside the tube in the form of vapour or steam. A visual reference can help to understand this in a better way.

           Further, the air-cooled condenser is sub-categorized into two kinds –

  1. Natural convectionHere, natural environmental air comes in contact with the coils present inside a machine and is used to produce cool air. This cool air replaces the warm air and hence continues the process of heat exchange.

They are made up of iron, steel and copper. The flow rate of the air is not that powerful because it is natural. Hence, it is used in the refrigeration systems that we use in our homes.

  1. Forced ConvectionAs the name suggests, this type of air condenser will use an external object for the inflow of air to go ahead with the process of heat exchange. 
  • Advantages of Air Cooled Condenser 
    • It has a low initial cost.
    • It requires less flow area.
    • It requires less cooling water.
    • It has low maintenance charges
  • Water-Cooled – As you can understand from its name, the water-cooled condenser uses water as an agent to release heat from the refrigerant. Water flowing through the tube exchanges the heat from the refrigerant vapour and then releases that heat through the outlet area.

They are used in the large refrigerating industries. Further, it has three sub-categories

  1. Double tube – A water tube is present inside the refrigerant tube.
  2. Shell and Coil Condenser – There is a coil of finned water tubing which is covered with a shell
  3. Shell and Tube Condenser – Here, the water tubes are present in a cylindrical shell, where the water is driven through the pipes and the refrigerant flows in the shell.
  • Evaporative It comprises a kind of pit through which the water is sprayed on the heated coil from above, and from the other side, the fan blows cool air from the bottom. Thus, both work simultaneously to discharge the hot air into the atmosphere.

It consumes less power as compared to the air-cooled and water-cooled condenser. It is mainly used in large cooling systems or where the external temperature is high.
