Industrial ERV


Dpurat specialists can design and supply a wide variety of energy recovery ventilation systems for commercial and industrial use. We cater to all sizes, budgets, and specifications, offering both cost-effective and custom-made options for specialized purposes.

What is it?

Industrial energy recovery ventilation products are specifically designed for large industrial spaces, such as offices and warehouses. These products have a higher maximum airflow rate than residential ERVs, which makes them ideal for commercial use. They transfer heat and humidity from outgoing air to incoming air during colder months, reducing the demand on heating and humidification equipment. Additionally, they remove humidity from incoming air during warmer months, reducing the demand on air-conditioning or dehumidification equipment. Our heat exchangers are independently designed and tested with patented technology, offering efficiencies ranging from 55% to 82%.

Why ERV?

It's crucial to maintain a pleasant indoor environment in workplaces since we typically spend most of our working hours inside. To ensure our comfort and well-being, it's important to have clean air at the right temperature and humidity levels.

In any scenario, Mechanical Ventilation with Heat Recovery (MVHR) solutions can make a significant difference. They can help create a healthier living and working space, while also reducing a building's carbon emissions and energy consumption.

Heat recovery systems are particularly popular in school classrooms and offices, as they keep CO2 levels below 1000 and filter the air to below PM2.5. This creates an ideal environment for optimal concentration and awareness.

Benefits of Industrial ERVs?

Enhance the quality of air indoors.

Decrease exhaustion and weariness by maintaining low levels of CO2.

Prevent the growth of mould and condensation.

Recover heat that is usually lost during cold days.

Control the flow of filtered outdoor air when it's warm.

Filter air, which minimizes the amount of contaminants and pollen

Provides a constant supply of fresh air with low level of airborne bacteria and germs.

Where does it applied?

Our Commercial MVHR units are versatile and can be utilized in various settings such as offices, hair salons, schools, shops, hotels, hospitals, public spaces, and retail establishments. Air volume can be reached to 100000 m3/h.

How Does It Work?

Our ERVs are equipped with two high-performance fans, one that draws fresh air into your home and another that pulls stale air out, ensuring optimal air circulation and ventilation. The heart of our ERV system lies in its advanced heat exchanger, which transfers heat and moisture between the two air streams passing through it but never mix. This means that in the winter, the incoming cold air is preheated by the outgoing warm air, while in the summer, the incoming hot air is cooled by the outgoing cool air. This results in significant energy savings, as your HVAC system doesn't have to work as hard to maintain a comfortable indoor temperature.

What Is It Used For?

Energy recovery ventilators are ventilation systems that provide equal amounts of fresh air and exhaust air. They can regulate the moisture levels in your home, which is especially useful during the summer when excess humidity can lead to mold growth and poor air quality.

If you lack an exhaust fan in your kitchen or bathroom, it's recommended that you install one. However, if you already have an exhaust fan in these areas, there's no need for another one. It's important to note that using an HRV/ERV to remove cooking fumes is not recommended as it could harm the heat exchanger core.

How Many Types?

4 types based on installation form

there are ceiling type, floor type, cabinet type, wall-mounted type, and others;

2 types based on air flow organization

It can be divided into one-way flow and two-way flow;

2 types based on indoor air pressure

there are positive pressure type, negative pressure type.

2 types based on heat exchanger

There exist two types: heat recuperation ventilators (HRV) and energy recuperation (or enthalpy recuperation) ventilators (ERV)


Industrial ERV


Businesses can benefit greatly from commercial heat recovery, especially since commercial buildings generally consume more power than residential properties. Offices with a proper ventilation system can provide their employees with fresh air while also reducing energy costs through efficiency savings.

Investing in commercial heat recovery can yield a high return on investment. While newer buildings typically have these systems in place, older buildings may require a customized solution due to limited space for retrofitting. Although retrofitting can be costly, the right system can provide a quick payback.


ERV systems help to lessen the frequency of your heater and air conditioner usage, which in turn decreases the likelihood of wear and tear. Additionally, they serve as a barrier against contaminants that may obstruct air filters or lead to other problems like unclean or damaged ductwork. By doing so, they can help you avoid expensive and inconvenient breakdowns, while also extending the lifespan of your HVAC system.

How do you know if you need an ERV?

If you're facing issues with the quality of air inside your house, an energy recovery ventilator can prove to be quite useful. In case you've noticed a stale or unpleasant odor, and your fans or air conditioning systems aren't doing much to improve the situation, an ERV can come in handy. It's a valuable device that can help you resolve such problems.

How big of an ERV do I need?

The usual size of HRVs/ERVs is designed to provide ventilation for the entire house with at least .35 air changes per hour. To determine the minimum CFM needed, you just need to multiply the square footage of the house (including the basement) by the height of the ceiling to get the cubic volume.

Can you oversize an ERV?

When it comes to an ERV, having a larger size is not an issue and is actually recommended. Having more ventilation is usually beneficial, as long as it is properly balanced and recovers some of the heat and moisture. This is unlike a heating and cooling system.
