Thermal Oil Secondary Circulation Pump System
In standard heating layouts, thermal oil coming directly from the boiler experiences pressure drops and heat loss, creating "cold spots" across different press platens. This uneven heat is the primary cause of un-cured glue, film bubbling, and board warping.
Achieve flawless surface lamination with the Thermal Oil Secondary Circulation Pump System from Geelong Machinery. Engineered as the critical temperature-control bridge installed between your primary heating boiler and the multi-opening hot press, this secondary loop system is indispensable for film faced plywood laminating lines and high-end board processes

FAQ
Q1: Why should I install a secondary thermal oil circulation system between my boiler and hot press?
A primary boiler system distributes heat over a long distance, often resulting in uneven platen temperatures inside the hot press. Installing a secondary circulation system creates an independent, fast-flowing oil loop directly at the press. This eliminates platen temperature differences, ensures uniform bonding, prevents board warping.
Q2: Is this secondary circulation pump system compatible with phenolic film paper lamination?
Yes, it is highly recommended for phenolic film paper laminating hot presses. phenolic-impregnated papers are extremely sensitive to heat variations; insufficient heat causes "white spots" (un-cured resin), while excess heat burns the film. This system provides the precise, stable temperature required for perfect phenolic surface finishes.
Q3: Can Geelong Machinery customize the system to fit my existing non-Geelong hot press?
Absolutely.Geelong Machinery provides fully customized retrofitting solutions. Regardless of your hot press brand or boiler type, we can design the piping layouts, valve interfaces, and structural skids to integrate seamlessly into your current production setup.
