Ensure efficient pump and motor operation in high ambient temperatures

Boiler rooms often exceed 50°C, which means feedwater pumps must be able to handle high ambient temperatures to remain operational.

For boiler systems with high feedwater temperatures, our air-cooled CRE pumps are ideal, as they can handle temperatures of up to 180°C. This is particularly useful in systems with economisers, which transfer energy from exhausts to the water, significantly increasing water temperature. Standard pumps cannot cope with such high temperatures, meaning you need specially designed pumps.

Additionally, our electronic pumps are equipped with high-efficiency motors (IE5/IES2) and integrated frequency drives that are designed to operate efficiently at full load operation at ambient temperatures up to 60°C. They require less cooling, ensuring your customers get a system that stays fully operational even in the hottest conditions. Unlike standard frequency drives that need to be derated when they go above 40°C, our motors with permanent magnet technology generate less heat, which allows them to maintain full shaft power at higher temperatures.

Built-in derating protection reduces power output if cooling is insufficient, while ‘flowlimit’ and ‘stop at minimum speed’ functions ensure the pump stops when the controller is in saturation, maintaining optimal performance.

Our solutions ensure that even under challenging conditions, your customers’ boiler feed systems operate efficiently and reliably, providing the necessary support for maintaining high performance.
