Perkenalan produk

A fresh air handling unit treats the full outdoor-air load required for ventilation, process exhaust replacement and building pressurization. Its treatment train normally includes weather intake protection, staged filtration, cooling and dehumidifying coils, reheat and optional humidification. Because outdoor conditions vary widely, coils and valves are selected for peak latent as well as sensible duty. The supply fan modulates to the scheduled ventilation quantity while frost protection and drainable wet sections protect the unit during seasonal operation.

Fitur utama:

The unit processes 100% outdoor air without recirculating contaminants from occupied or process spaces.

Deep cooling followed by controlled reheat separates moisture removal from final supply-air temperature.

Intake screens, dampers and prefilters protect coils from weatherborne debris and particulate loading.

Supply-air volume can track facility exhaust or pressure demand through variable-speed fan control.

Kekhawatiran produk pelanggan

Outdoor air imposes the widest temperature, moisture and contamination range on a cleanroom HVAC system.

Humid summer air raises cleanroom dew point even when room temperature is acceptable.A deep cooling coil removes latent moisture before reheat establishes the required supply temperature.

Exhaust systems pull the cleanroom negative during high process operation.Fan airflow tracks the measured replacement-air or pressure requirement.

Wind-driven rain reaches filters and shortens their service life.A weather louver, drainage section and staged prefiltration protect internal treatment components.

Cold outdoor air freezes the first water coil during low-flow operation.Low-temperature detection, preheat and coordinated damper/fan control protect the coil circuit.
