Forced draft cooling towers

A forced draft cooling tower is particularly well-suited for locations with limited headroom or heightened noise control requirements. Since the fans are located on the sides of the housing, the overall height of the system can be kept relatively low. In addition, silencers can be integrated in front of and behind the fans. Indoor installation with connection to appropriate air ducts is also possible.

At MULTI Kühlsysteme, we are committed to the continuous development of modern cooling technology. How well a forced draft cooling tower performs in everyday operation is rarely determined by its rated capacity alone, but rather by the details that, during continuous operation, influence energy consumption, hygiene, and maintenance requirements.

This is exactly where we focus with the MC-D series. From fan control to material selection to water flow, every component is designed to ensure that your cooling tower continues to operate reliably and economically even after many years. These features set the series apart:

• Adjustable EC fans: The speed adapts to actual demand, saving electricity and reducing operating costs.
• Robust stainless steel housing: The housing, basin, and hood are made of corrosion-resistant stainless steel sheet metal in a bolted construction, ensuring a long service life even under harsh industrial conditions.
• Well-designed water drainage: An angled basin allows residual water to drain completely, while generously sized industrial nozzles prevent clogging. Both features contribute to hygienically sound operation in accordance with VDI 2047 Part 2 and the 42nd BImSchV.
• Adaptable to the installation site: Whether it’s additional sound insulation, PLC integration for operational monitoring, or remote access via MULTI CONNECT, the towers can be fully tailored to your operations.
• Ready for upcoming regulations: The models already comply with the EU Ecodesign requirements that will take effect in 2026.
• Flexible substructure: Available in hot-dip galvanized steel or stainless steel, suitable for virtually any installation site.

Our cooling technology for your business is 100 percent manufactured in Germany. Complete assembly at our headquarters in Aue also shortens transport distances and reduces CO₂ emissions, a factor that is becoming increasingly important in competitive bidding processes.

In a forced draft cooling tower, silencers can be installed both upstream and downstream of the fans. This provides various options for adjusting noise emissions to meet the requirements of the specific site. This can be particularly important during nighttime operation or near residential areas. For the MC-D series, noise control measures are designed to suit local conditions.

The MC-D cooling towers use variable-speed EC fans whose output can be adjusted to meet current cooling demands. Depending on the configuration, the MC-D 750 is equipped with two or four fans, while the MC-D 1500 has four or six. The connected load per fan is 5.85 kW. Demand-based speed control helps reduce energy consumption, particularly during periods of lower load.

A cooling tower of this type is an interesting solution when high cooling capacities must be provided in a limited space. This applies, for example, to buildings with low ceiling heights, retrofit projects, or locations near residential areas. Thanks to its sound insulation capabilities, the system can be adapted to demanding acoustic conditions. The forced draft design also offers significant advantages for planned indoor installations.

A forced draft cooling tower can be operated energy-efficiently through demand-based fan control. The EC fans in the MC-D series adjust their speed to the cooling capacity currently required. As a result, the system does not have to operate continuously at maximum fan power. This can reduce electricity consumption and thus operating costs, particularly during part-load operation.
