AnyHz FST‑650L VFD Retrofit Delivers 32% Energy Savings for Indonesia Palm Oil Mill Circulation Pump System

Medan, Indonesia — October 28, 2026 — Anyhertz Drive (Shenzhen) Co., Ltd. (AnyHz), a global specialist in variable‑frequency drive manufacturing, has completed a full energy‑saving retrofit project for a large‑scale palm oil processing mill in North Sumatra, IndonesiaANYHZ.

The mill originally relied on traditional valve‑throttling regulation for its large circulation pump group. Even during low‑production shifts, pumps kept running at full‑speed, generating massive unnecessary power loss. Motor frequent direct‑on‑line starting also brought mechanical shock, shortened pump seal and bearing service life, and increased routine maintenance costs.

AnyHz technical team carried out on‑site audit and load analysis. Based on real‑time production fluctuation characteristics of palm oil processing, the team selected FST‑650L general‑purpose VFD series for 28 sets of circulation pump motors ranging from 30 kW to 110 kW. The VFDs realize closed‑loop automatic speed adjustment according to pipeline pressure and flow requirements, replacing old mechanical throttling control completely.

Beyond energy savings, variable‑speed operation smoothed pipeline pressure fluctuation, avoiding frequent pressure spikes that damaged pipe fittings. The mill calculated the project return‑of‑investment cycle at approximately 14 months.

“Palm oil processing plants face heavy energy pressure, especially for continuous pump‑and‑fan loads. Simply changing control logic via VFD retrofits can unlock huge energy‑saving potential without overhauling main process equipment,” commented AnyHz senior application engineer. “Our FST‑650L is well‑adapted for tropical high‑temperature, high‑humidity workshop environment in Southeast Asia, with robust thermal design and dust‑resistant cabinet options.”

So far AnyHz VFD products have entered more than 100 countries worldwide, delivering localized technical support for water supply, printing, food‑pharmaceutical, mining, and agricultural processing industries AnyHz.
