Silica & Electronics Manufacturing
Process heat for sand processing, cleanrooms and specialty glass
A new industrial frontier is taking shape in Central Luzon. The Pax Silica initiative — with its proposed AI and advanced-manufacturing hub at New Clark City and expanded high-purity silica sand and quartz processing in the region — is expected to pull an entire ecosystem of plants along with it: sand processing and refining, semiconductor assembly, testing and packaging facilities, specialty glass lines and the supplier industries around them. Almost every link in that chain runs on industrial heat.
Upstream, turning raw sand into high-purity silica is heat-intensive work. Washing circuits use large volumes of heated water; purification steps such as acid leaching typically run at elevated temperatures sustained by steam; and every tonne of processed sand must be dried before shipment — classic duty for steam or thermal-oil fed dryers. Fire-tube WNS units suit batch washing and leaching loads, while water-tube SZS boilers carry the continuous steam demand of larger refining lines.
Downstream, electronics-grade facilities need heat of a different character: precisely controlled steam for cleanroom HVAC humidification, stable hot water for ultrapure-water plants and facility services, and thermal-oil systems where specialty or solar glass processing calls for high temperatures at low pressure. These are exacting, always-on loads where N+1 redundancy and tight controls matter more than raw capacity — the same reliability engineering we already apply in pharmaceutical and food plants. Wherever these projects land, our engineers can size the heat plant around the actual process from day one.
