How Do You Size a Commercial Dehumidifier for a Philippine Facility?

Commercial dehumidifiers should be sized from the facility’s moisture load and required indoor conditions, not floor area alone. Engineers consider outdoor-air infiltration, ventilation, occupants, wet products or processes, door openings, building-envelope leakage, temperature, starting humidity, and the time allowed to reach the target. A liters-per-day rating is useful only when its test temperature and relative […]

What Is Pre-Insulated Duct and When Should a Project Use It?

Pre-insulated duct is fabricated from rigid insulated panels that form both the air passage and thermal envelope, usually with protective facings. It can reduce installed weight and combine fabrication with insulation, but successful use depends on panel type, fire performance, vapor sealing, reinforcement, joint quality, pressure class, and installation workmanship. It should be evaluated as […]

How Does an Electrostatic Precipitator Treat Restaurant Kitchen Exhaust?

An electrostatic precipitator, or ESP, removes grease and smoke particles from kitchen exhaust by electrically charging them and collecting them on oppositely charged plates. It can reduce visible emissions and downstream grease loading, but it does not replace capture hoods, grease filters, duct cleaning, fire protection, odor treatment, or compliant exhaust discharge. Successful performance depends […]

How Should Philippine Offices Monitor Indoor Air Quality?

An effective office indoor air-quality program measures conditions that can guide action, not just values that look impressive on a dashboard. Carbon dioxide, fine particles, temperature, and relative humidity are common starting points. The correct sensor set depends on occupancy, outdoor pollution, building materials, activities, ventilation, and known hazards. Monitoring does not clean the air […]
