Everything You Wanted to Know About MicroChannel Condenser

microchannel condensers

While buying an air conditioner people look for cooling capacity, and energy efficiency but nobody notices the condenser. So the condensers are equally important and help in long-term durability, cooling effectiveness, etc.

Microchannel condensers are best used in HVAC air conditioning systems.

It is the best option to target the needs of the HVAC industry. Furthermore, this helps to improve efficiency and cost also. In a Microchannel heat exchanger, only one fluid flows either water or refrigerant flows through the tube or enclosed channels while the air flows between the connected fins.

Types of Microchannel Condenser

  • Air-cooled condensers
  • Water cooled condenser
  • Combined water and air-cooled condenser

These condensers are also called evaporative condensers and they are cooled by spraying water from above and then this cold air enters from the bottom and is blown across the coils.

The refrigerant inside the coil condenses as the water evaporating from the coil generates a cooling effect. The coil’s refrigerant gas is heated. Just by combining the water that was sprayed with the large column of moving air that was provided by the fan, it transformed into a liquid condition. Using a pump, the water that does not evaporate is cycled once more.


Many industries like transportation and chemical processing have been using micro-channel heat exchangers for decades. Additionally, due to its improved efficiency, it is widely used in the HVAC system. So due to its increased demand, the manufacturers are focusing on aluminum materials and brazing construction. As it is made up of single material there is a consistent heat transfer rate. It produces strong metallurgical alloy at the joints due to the high temperatures used in brazing. Thus, in this way, the resistance to heat transfer is reduced. We focus on limiting condensation, and corrosion thus improving the fluid flow. 

Benefits of Microchannel Condensers

There are multiple technical benefits due to small hydraulic diameter channels. It is best to use a microchannel heat condenser in the HVAC industry due to its efficiency. It provides more surface area to refrigerants than larger tubes in the same space. It also requires less refrigerant. Due to its increased efficiency, it means smaller fans are used and thus lowering the overall energy of the system. On the other hand, there is less noise due to the small fans. 

Comparison Between Copper And Aluminum Condensers

Aluminum condensers are light in weight as compared to copper condensers.

Condensers are always in contact with air so they are more resistant to corrosion. However, both are resistant to corrosion because an air conditioner’s cooling capacity is widely affected.

Aluminum Radiator Benefits And Its Working Process

aluminum radiator

Although we all have heard of radiators, most of us are unaware of their purpose. An aluminum radiator is an important component of a vehicle’s cooling system. The primary function of the radiator is to prevent it from overheating by regulating its temperature. When the radiator doesn’t work properly there is an increased chance of overheating the vehicle. 

In earlier times, there were radiators made from copper or brass in most vehicles but eventually, these radiators are replaced with radiators of different materials like an Aluminum radiator.

Benefits of Aluminum Radiator :


  • Cost-effective 

It is less expensive and easy to repair than copper and brass. Additionally, they are less expensive than plastic radiators.

  • Lightweight 

They are lighter and due to aluminum radiators and being light in weight the vehicle is more fuel efficient.

  • Durable

There are fewer chances of radiators cracking as they are durable even under high temperatures.

  • Corrosion resistant

Less susceptible to corrosion and rust too.

  • Recyclable

These aluminum radiators are recyclable and are one of the most abundant metals on Earth.

One of the important benefits of these radiators is that they are made up of recyclable metal which is also good for the environment. Aluminum radiators are conductors of heat and absorb it faster, so it allows the hot coolant going through tubes to cool more quickly.

How does an aluminum radiator work?

The main goal of a car radiator is to keep the vehicle cool. The heat is generated when the engine in a vehicle burns fuel. So it is the utmost to remove this heat from the engine and prevent it from damage.

Thus radiators are an important component to eliminate excessive heat. Further, the thermostat detects the excess heat and then the coolant or water is released by the radiator and absorbs the excessive heat.

The excessive heat is absorbed by the liquid and is sent to the radiator which works to blow air across it and thus cool it down. During this process, the radiator utilizes thin metal fins which are effective and they allow the air to escape outside the car. The fins are helpful to blow air across the radiator.

Automotive radiator price and how much they last for

Check out the best quality, genuine and high-performance car radiators available at Narain cooling. Additionally, these radiators are eco-friendly and they can run for a long. So the automotive radiator price is worth paying as they are ideal to use. An aluminum radiator lasts for a longer period, usually 8-10 years.

What are the common signs of failure of automotive radiators?

Every car owner or driver wants to avoid being on the side of the road due to overheating of the engine. So to avoid such a situation vehicle owner must keep a regular check about the signs of failure of the radiator to avoid expensive repairs.

Some common signs of failure of the radiator are: 

  • Rise and fall of temperature in the cluster temperature gauge.
  • Sometimes there might be the smell of smoke under the hood of the car.
  • There are chances to collect the coolant under the vehicle and this is usually green in color.
  • On the components of the cooling system, rust can be visible.
  • However, there are mechanics to keep a check on the cooling system and radiator so they can last long.

Truck Radiator Importance And How It Prevents Overheating Of Vehicles.

truck radiator

Most people are not aware of the importance of radiators. The Truck 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 Truck Radiator :

1) The core
2) The pressure cap
3) Outlet Inlet tanks
4) 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 Heavy Truck 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 Truck Radiator

A vehicle may be heated again and again, the Truck 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 Air Cooled Condenser Are Best To Remove Excessive Heat

Air Cooled Condenser

Air Cooled Condenser is used in various applications as they are highly efficient. They are high in performance and are widely used in the radiator and automotive condenser coils. The condensers are resistant to corrosion and have better heat transfer. The Air Cooled Condensers meet all the cooling requirements as they have high heat exchanger capacity.

Types of Microchannel (Air Cooled Condenser)

Based on the condensing medium, three different types of Air Cooled Condensers are used to remove heat from the system. This depends on the situation and which condenser is appropriate for the particular situation.

There are three types of Microchannel condensers

  • Water cooled condensers 
  • Air-cooled condensers
  • Evaporative condensers

Water cooled condensers

These condensers are used with compressors of 1hp or more. This condenser is economical as this water is used. In this, the water cools the hot refrigerant and converts it into liquid. These condensers are widely used where there is a continuous supply of water.

There are three types of water-cooled condensers

  • Double tube
  • Shell and coil condenser
  • Shell and tube condenser 

Air Cooled Condenser

A finned continuous tube coil makes up condensers. Vapor from the compressor discharge enters the top of the coil, and liquid exits the bottom, flowing into receivers beneath the base. The condenser coil is blown with air by a fan that is installed on the pulleys of the compressor motor.

The unit must be located in a ventilated and cooled place. If the temperature of ambient air is low then less power is required for the same capacity. Its main advantage is that it is simple and the installation cost is also low. They are mostly used in water coolers, air conditioners, etc. This air is used as the external fluid to reject heat from the system. Moreover, these condensers have copper coils and the refrigerant flows through them. 

The Air Cooled Condensers are of two types.

  • Natural convection
  • Forced convection

Natural convection

When the air comes in contact with the hot coil, it absorbs refrigerant heat inside the coil and increases the temperature. The warm air replaces the cold air as it is lighter in weight and also the cold air touches the hot coils to reject heaters. This process continues till the refrigerant loses heat.

Forced convection

The heat from the refrigerant inside the coil is removed by a fan or blower. The fan blows the air inside the coils. The fins in these condensers are tightly placed. It is mostly used in air conditioners, water coolers, etc.

Evaporative condensers

Air flows upward into the refrigerant coil through spray, eliminator, and fan and is discharged at the top of the unit. Refrigerant enters the top of the coil and flows down 

Coolants enter the coil at the top and flow downward. The receiver, which is frequently housed in the water tank, receives the condensed liquid and uses it to further cool the liquid refrigerant. A pump that is placed on the unit draws water from it and releases it through a spray nozzle that points downward above the refrigerant coil.

The circulating water evaporates and is transferred to the tank through a valve. The salt concentration is increased in water due to evaporation. Due to the increase in salt concentration water treatment is recommended.

Comparison between the three condensers

Evaporative condensers are mostly used in places where the supply of water is less. They are also more cost-effective than water-cooled condensers. When the weather is cold, the evaporator is kept outside and the water pump is turned off to avoid freezing water.

Additionally, the maintenance cost of air-cooled condensers is low in comparison to water-cooled condensers.

Why are PTC Heaters Safe And Powerful?

ptc heaters

Traditional heating products are prone to overheating, and PTC heating elements have an open-loop self-regulating design that prevents them from overheating. Unlike conventional heating, these PTC heaters do not need coils or cables, so they save money and are much more efficient.

PTC heaters consist of heating discs that are made from ceramic materials. They have automated systems and thus reducing the risk of overheating. These heaters are safe, powerful, and energy-efficient, which results in outstanding heat production and transfer in even small areas.
In self-limiting PTC systems, less money is needed on specialized equipment to prevent overheating. In addition, the PTC heater runs more smoothly, and less maintenance is required.

The Two Types of PTC Heaters

PTC Fin air heaters and
PTC Honeycomb air heaters
These heaters have several benefits over traditional heaters.

Is it Cost-Effective to Run PTC Heaters?

These heaters are highly efficient in terms of energy usage. The cost of running a circuit would be lower if it used no more electricity than was required to reach a specific temperature. Furthermore, no additional equipment is needed to manage the temperature, thus lowering expenditures.
However, PTC heaters are less expensive to run based on those two factors and are less costly than a standard resistive heater.
These heaters are incredibly cost-effective to install and operate and require very little maintenance over the device’s useful life. For industrial use, there is no better way to generate heat at a cheaper cost.

PTC Fin Air Heater

Fin PTC air heaters are self-regulating, temperature-limiting systems that eliminate the risk of overheating, because of their self-regulating features. Fin PTC air heaters always function at maximum safety levels. This results in increased conductivity and efficiency, resulting in a heating system that lasts longer than others.
Due to large aluminum fins, these machines circulate air, ensuring homogeneous heat transfer. The users can adjust airflow volume to regulate the system at any time.

PTC Honeycomb Air Heater

These heaters are extremely safe and energy-efficient for everyday usage as they operate at temperatures below the point of combustion of paper. The small discs serve as the heating element and can be directly connected to a power source to convert electricity to heat.


PTC heating elements in industrial applications

PTC heaters are ideal for applications that require less voltage and electricity but require temperature control at all times.
The enclosed cabinets and electronic devices require precise temperature control. PTC heating elements provide an ideal solution to remote SCDA where electronics need protection from extreme environments.

Why is it better to use PTC heaters?

PTC heaters reduce the risk of overheating. It is efficient and safer to use PTC heaters and is ideal for products requiring safe and uniform heating.
As the temperature rises, the PTC materials restrict current flow, and If the temperature drops, the materials allow the current to flow.
