Flange-mounting in variable speed drives

Smarter cooling for tough conditions

ABB’s flange-mounted drives offer a compact, reliable solution for industrial and infrastructure applications exposed to dust, humidity, and extreme temperatures. Designed for push-through (flange) installation, the drive's heatsink is mounted outside the cabinet wall, while only the control section remains inside. This design separates the airflow between the control electronics and the heatsink, significantly reducing the heat load within the cabinet.

With less internal heat, your electrical enclosure can be designed with smaller cooling fans, fewer filters, and reduced need for air conditioning systems—resulting in savings on space, cost, and energy. The IP55-rated (UL Type 12) flange and heatsink ensure robust protection against dust and low-pressure water, making this solution ideal for harsh environments like mining, oil & gas, rubber, textiles, and even HVAC, water, and wastewater sectors.

Product availability

Flange mounting is available for a wide range of ABB drives, including ACS880 industrial drives, as well as ACH580-31 and ACQ580-31 variants for HVAC and water applications. Offered as a standard or plus code option depending on the drive type, this robust installation method helps simplify cabinet design and improve reliability in harsh environments.

Key benefits

Simplified Cabinet Design

With the heatsink outside the cabinet, internal components stay cooler allowing for smaller, more efficient cabinet layouts.

Reduced Cooling Requirements

Less heat inside the cabinet means smaller fans or heat exchangers are needed, lowering system complexity and cost.

Lower Air Conditioning Costs

By channeling heat outside, the drives reduce the need for HVAC systems in the electrical room—saving on investment and energy.

Robust for Harsh Environments

IP55-rated flange and heatsink provide reliable protection against dust and water, ideal for outdoor or dusty conditions.

Improved System Reliability

Lower heat load inside the cabinet leads to more stable performance and longer equipment life.

Minimized Filter Maintenance

Reduced air circulation within the cabinet extends filter replacement intervals and reduces maintenance needs.

Space-Saving Installation

Flange mounting enables more compact cabinets— especially valuable in space-limited applications like mining or marine.

Flexible Cooling Options

Compatible with back-channel and air-duct cooling systems to direct heat away from critical areas.

Available for Specialized Applications

Offered in regenerative and ultra-low harmonic variants for advanced performance and process optimization.
