In contrast to direct free cooling, in which the outside air is used directly for cooling, indirect free cooling transfers the cold via a pipe system to a water-glycol mixture. The mixture is cooled with fresh air using a drycooler. Air-water heat exchangers are then integrated into the cooling water circuit of your cooling system. The heat load is dissipated to the outside air via the heat exchangers. In an optimal case, the entire system can realize the necessary cooling capacity of your plants completely by indirect free cooling. Power-intensive chillers are only switched on when the outside temperature is too high (over 18 degrees).

From many customer projects, we have developed useful features such as fans that can be opened upwards for cleaning, and devices that are specially coated to protect against aggressive outside air.


Chillers are a classic method for your cooling applications. 

In an air-cooled chiller the condenser cooled by a fan absorbs the heat from the evaporator in the cooling water circuit. It is controlled by a controller whose function is comparable to that of a thermostat. This allows you a high reliability and availability.

In a water-cooled chiller the condenser is cooled by external liquid, instead of an air-to-water cooling coil. This makes the chiller more compact and it can be placed either inside or outside the building, making it more versatile in locations where space is scarce.

Here we use special devices of the most modern design, including modern Turbocor compressors and Siemens S7 controls according to the equipment standard of the customer.


Absorption Chillers use the hot wastewater for cooling, replacing the electrical energy with heat energy in the chilling process. Refrigerants with GWP (Global Warming Potential) are completely absent.

Our new, special low-temperature absorber can be operated with 70-degree hot water around 20 degrees colder than previous solutions on the market. This opens up many more possibilities for the customer to produce cold water from waste heat at a low temperature with almost no additional use of electrical energy.


Adiabatic Cooler

Adiabatic coolers use water evaporation as the cooling method. By vaporizing the sprayed water, there is a cooling effect that can be utilized in the system.

Climate cabinets

Climate cabinets make the backbone of the cooling system. The Paper Line cooling cabinets by BM Green Cooling are purposefully engineered for paper industry, including features like coated pipes and coils, Siemens S7 as standard control units and extremely large coil surface areas to optimize the fluid temperatures.

L-units for ceiling installation

L-Units offer a space saving solution for climate cabinets, offering all the benefits from our Paper Line climate cabinets, but requiring less foot print in the E-room.

Air handling units

Air Handling Units we offer are state of art and made in Germany. When the space inside the building is limited, cooling can be carried by Air Handling Units placed outside. With only the ducts inside the building, this can solve many problems in moving the air when the cooled space is tight.

Due to the lack of space, some control rooms do not allow the use of our indoor special air-conditioning cabinets for the paper industry.

That’s why we use project-related outdoor climate cabinets that are positioned outside the control room.

Such devices can also be positioned above, below or even in the area of ​​the paper machine. From there, they then air-condition the control room.

Heat exchangers

Heat exchangers are essential for every cooling system. We offer water-water heat exchangers that are specifically designed for the demanding conditions they are intended to work in.

In order to minimize the difference between the ambient temperature and the medium temperature, and thus to increase the possible free cooling percentage per year, particularly powerful, optimized heat exchangers are used here, which are often implemented in redundant configurations.
