Counterflow Heat Exchanger

A counterflow heat exchanger is an integral part of our custom-made ventilation systems designed for industrial and commercial use. Counterflow heat exchangers play a crucial role in efficient heat and energy exchange within the ventilation process.

How does a counterflow heat exchanger work?

A counterflow heat exchanger operates by directing incoming and outgoing airflows in opposite directions without actually mixing them. This allows for optimal utilization of the heat energy in the air, as the warm air from the exhaust is transferred to the cool air from the intake. This maintains a comfortable temperature in the indoor environment while minimizing energy consumption.

Benefits of using a counterflow heat exchanger

Integrating a counterflow heat exchanger into your ventilation system comes with significant energy savings and a reduction in heating costs. This method of heat recovery not only contributes to a more sustainable operation but can also result in substantial cost savings over time.

Counterflow heat exchangers enable a high degree of heat transfer between incoming and outgoing air, resulting in significant energy savings.

Another advantage of counterflow heat exchangers is their ability to improve indoor air quality. By recycling heat from the exhaust air, the need for constant heating of fresh air from outside is reduced, minimizing the influx of potential pollutants. This creates a more comfortable working environment and can have positive effects on the health and productivity of employees.

Counterflow heat exchangers are suitable for large temperature differences, as they are effective even when there are significant variations between incoming and outgoing air temperatures.

It is also worth mentioning that our counterflow heat exchangers are designed with a focus on durability and long lifespan. We use high-quality materials and advanced production methods to ensure reliable operation and minimal maintenance. This not only helps preserve the system's performance but also reduces the need for frequent repairs, resulting in cost savings for your business.

Drawbacks of using a counterflow heat exchanger

It's important to note that there are certain drawbacks to counterflow heat exchangers. To maintain optimal performance, they require regular inspection and cleaning to avoid the accumulation of particles and contaminants that could potentially affect efficiency. Additionally, the complexity of the system may at times require professional advice to ensure optimal operation, similar to rotary heat exchangers and cross-flow heat exchangers.

Although there are certain drawbacks to counterflow heat exchangers, at Bardram, we are dedicated to minimizing these issues through a combination of careful planning, installation, and maintenance. Our experienced technicians are always available to provide professional advice, ensuring you can maintain an optimal ventilation environment in your business.

Ventilation is a key solution for companies that need to maintain production environments and keep turning profits. Knowledge and insight about your company are important to us when we design solutions.


Process extraction

In rooms with high temperatures, steam, or contamination, process extraction is the way to go. Dust, heat, or contamination can be extracted from the source and create a better environment for your employees.


In all production rooms, machines and other processes will release heat. To maintain a good working environment, it is necessary to cool these rooms down — our products will help with this.


A dry production environment is key to safety. Steam and condensation on your work site can cause big challenges and loss of production time. Our solutions are designed to keep work areas dry so your team can get back to work sooner. 


Public guidelines determine how much noise is allowed in your work area, and some production units are too loud. Whether excess sound comes from processes in your production or ventilation units on the roof, we can reduce noise and make both employees and neighbors happy.


The smell of food can be wonderful, but if you are surrounded by it every day it might become too much. With different techniques, we can help you limit the odors created during production inside and outside of the working area.


Save unnecessary expenses by getting your current ventilation system checked. Usually, we can find ways for you to save electricity and money, by reusing the power already generated during production.


We have created our own products, that enables dehumidifying and cooling which will lead to a better working enviroment and increased production time.
