Hebei Hanlan’s Balance Load Bank Runs Stably at an Overseas Compressor Station in Harsh Conditions

• Next

Hebei Hanlan Environmental Technology Co., Ltd. recently announced the successful commissioning and stable operation of its self‑developed balance test load bank for a compressor station at an overseas project site characterized by extremely harsh environmental conditions. The equipment has earned recognition from the customer for its dependable performance in the field.

Faced with an outdoor, dust‑prone operating environment, reliability was the foremost challenge. From the initial design phase, Hanlan’s load bank was engineered with environmental adaptability as a top priority, directly targeting the severe site conditions. The unit is designed to withstand ambient temperatures ranging from ‑15 °C to +48 °C, and is suitable for altitudes up to 1,000 meters and humidity levels below 80%.

The load bank enclosure is fabricated from corrosion‑resistant 304 stainless steel, and incorporates a sealed system with automatic louvers, achieving a static protection rating of IP54 or higher to effectively shield against sand and dust ingress. Critical components – including a dual‑power Automatic Transfer Switch (ATS) from a leading brand, electrical elements with ample safety clearances, and insulated protection for all exposed conductors within the cabinet – collectively form a robust safety architecture. All wiring and components are marked with clear, corrosion‑resistant labels, greatly facilitating accurate and efficient maintenance over the equipment’s service life.

The dummy load bank is equipped with a high‑performance PLC controller that continuously monitors the real‑time output of the generator set. When the load factor drops below the preset health threshold of 50%, the system automatically, accurately, and seamlessly engages the load bank, ensuring that the generator set consistently operates within an ideal load range above 200 kW. This prevents internal damage caused by prolonged low‑load operation, significantly extends overhaul intervals, and reduces the risk of cylinder carbon buildup, accelerated wear, and other faults associated with light‑load running.

After delivery to the overseas site, the complete system underwent installation and commissioning, and has since been operating continuously in sandy and dusty conditions. The automatic load engagement and disengagement actions have been consistently accurate, with all electrical parameters remaining stable. This successful case clearly demonstrates that Hanlan’s balance load bank products are well‑suited to harsh outdoor conditions such as those encountered at oil and gas compressor stations – with high dust loads and wide daily temperature variations – effectively protecting generator sets, lowering long‑term maintenance costs, and ensuring reliable, stable power supply at remote field sites.
