Effective Heat recovery ventilation systems

Genvinding af varme

By implementing heat recovery ventilation, you can drastically reduce your energy consumption and thereby minimize your electricity bill. Typically, surplus energy comes in the form of heat, steam, or water, where the potential is not fully utilized. At Bardram, we are dedicated to helping you harness this untapped energy reservoir through advanced heat recovery systems.

Optimal Utilization of Heat Recovery

In certain production processes, excess heat is generated, which can be efficiently utilized in other production areas. The most economical solution is achieved when there is a parallel process that can directly receive the collected heat energy. The higher the temperature of the outgoing heat discharge, the better the economic benefits.


However, it is not always possible to channel the collected heat directly to other processes. This can lead to fewer operating hours where the benefits of heat recovery are realized. Alternatively, heat accumulation can be implemented, but both approaches extend the payback period for the heat recovery system. Our expertise in heat recovery has been crucial in various industries, including:

Pig production

In pig production, efficient heat recovery plays a crucial role in sustainable operation. Our ventilation systems with heat recovery harness heat from pig ovens in pig slaughterhouses. Our systems capture and reuse the heat from the ovens, reducing not only energy costs but also contributing to more environmentally friendly production. The optimized heat recovery also supports precise temperature control in stables, crucial for the well-being and productivity of pigs.

Poultry production

In poultry production, maintaining precise temperature and humidity levels is essential to ensure optimal production conditions. Our ventilation systems with heat recovery are designed to utilize excess heat from exhaust systems used in scalding and plucking chickens.

Slaughterhouses

In the slaughterhouse industry, effective heat recovery is essential to minimize energy waste and optimize production processes. Our custom-made ventilation systems with heat recovery utilize excess heat from exhaust systems in slaughterhouses, contributing to savings in energy costs.

Reduced Energy Consumption

The energy consumption of a ventilation system is crucial for its efficiency and depends on three primary design parameters:


Regulation of the system's performance

We adjust the system's performance according to current needs and outdoor temperatures. This ensures optimal energy use and comfort in your production environment.

Design of capacity and ventilation principles

Our professional ventilation experts consider capacity, ventilation principles, injection system, fans, pressure drop, and insulation to ensure that your ventilation system operates efficiently and economically.

Recovery of heat from exhaust air

Heat recovery is crucial to minimize energy waste. By utilizing heat from exhaust air, we can significantly reduce your energy consumption.


These three parameters work in harmony and must be balanced in relation to the need to heat the incoming supply air. Our approach also considers the customer's requirements for payback time, as this is crucial for the choice of energy-efficient heat recovery systems. Whether our customers aim for a payback period of 3 months or 10 years, we respect their decision.

Custom solutions for ventilation with heat recovery

We do not offer a standard solution, as all businesses and production environments are unique. Instead, we use the customer's payback time as our guide during the design process. This ensures that we tailor the most energy-efficient heat recovery system to your specific needs and conditions. Bardram is your reliable partner in heat recovery technology, offering a wide range of advanced solutions, including:


Rotor exchangers

Rotor exchangers are advanced heat recovery units used in ventilation systems to optimize energy efficiency. These units use a rotating heat exchanger, allowing the transfer of heat between the incoming and outgoing airflow. Rotor exchangers are particularly effective as they allow high heat transfer while minimizing the risk of contamination between the two airflows.

Counterflow exchangers

Counterflow exchangers are a common type of heat exchanger used in ventilation systems. These units allow the air in the incoming and outgoing flows to pass each other in opposite directions. This configuration enables efficient heat transfer, as the warm air leaving the building transfers its heat to the fresh air being drawn in. Counterflow exchangers are known for their high heat recovery capacity and are ideal for situations where space is limited.

Crossflow exchangers

Crossflow exchangers combine the characteristics of both counterflow and parallel flow exchangers, representing a versatile solution for heat recovery. These units allow the incoming and outgoing airflow to cross each other at an angle, enabling more efficient heat transfer compared to counterflow exchangers. Crossflow exchangers are suitable for applications where high heat recovery is crucial, contributing to maintaining optimal temperatures in the building by recycling the heat from the exhausted air.

Connected batteries

Connected batteries represent a key component in optimal energy management systems. These advanced battery solutions are designed to work together and evenly share the load, ensuring a stable and continuous energy supply.

Mixing chamber systems (recirculation)

Mixing chamber systems, including recirculation systems, represent an environmentally friendly and energy-saving approach to industrial processes. These systems enable the reuse of resources by recirculating and reusing materials or media, reducing the need for continuous supply of new resources.
