What is high-pressure misting?

Adiabatic technology producing 5-10 µm micro-droplets via 70-100 bar pump + stainless nozzle. Plunger pump + inverter standard. 20-2,000 kg/h.

Four modules: water conditioning (filter+RO+UV+tank), HP pump (70-100 bar AISI 316), distribution + nozzle matrix (AISI 316L), control panel (PLC+sensors+BMS).

Why 5-10 µm droplet target?

Evaporation time scales with d². 5 µm ~0.2 s, 10 µm ~0.8 s, 50 µm ~20 s. The 5-10 µm band travels 0.3-1.2 m at 1.5 m/s airflow and evaporates before floor.

Why RO + UV mandatory?

Two reasons: (1) Mains clogs nozzles in 2-4 weeks, RO drops hardness <5 ppm. (2) Aerosol Legionella risk, UV (30-40 mJ/cm²) inactivates. Tank circulation + Ag-ion cartridge add-on.

Three components: air-change + infiltration + process. 5,000 m² × 4 m × 2 ACH × 30→65% RH ≈ 150-200 kg/h. Summer-winter ratio 1:3.

Natural-choice applications?

Five bands: textile weaving/spinning/dyehouse, print + packaging, wood + furniture, greenhouse + agriculture, large warehouse + logistics. High capacity + medium-low hygiene + year-round.

Why high-limit sensor mandatory?

Safety layer against local overshoot. Watches 85% RH; when exceeded, stops pump and closes solenoid. Prevents condensation, duct dripping, contamination.

Maintenance schedule?

Four frequencies: Monthly (30-45 min) (filter+nozzle+alarms; Quarterly (1 h)) filter change; 6-monthly (3-5 h) (nozzle clean+tank disinfect; Annual (1 day)) UV lamp+performance; 24-36 monthly, RO membrane.

How to choose SKH vs SKVF?

Three axes: ceiling ≥4 m → SKH; 200 kg/h or >5,000 m² → SKH; small volume → SKVF/SKV. Standalone → SKVF; AHU-integrated → SKV; production hall → SKH. Hybrid common.

NKT proposal package?

Six steps: site analysis + load calculation + pump/nozzle sizing + RO+UV pretreatment + control strategy + commissioning + 6-month validation. Maintenance contract included.

What Is Adiabatic Humidification? How It Differs from Steam Humidification

Adiabatic humidification raises humidity by atomising water or evaporating it from a wetted surface, an isenthalpic process that cools by drawing heat from the air. Thermodynamic difference from steam, three technology families (SKH/SKV/SKVF) and application matching.

Hygiene Risk and Water Treatment in Adiabatic Humidification
