Jinsheng Mist Forest-High Pressure Mist System is one of the leading manufacturers and suppliers of evaporative cooling fog unit in China. If you're going to wholesale cheap evaporative cooling fog unit made in China, welcome to get free sample from our factory. All customized products are with high quality and low price.
The Evaporative Cooling Fog Unit is a packaged high-pressure misting system for localized evaporative cooling in workshops, warehouses, logistics areas, loading zones, greenhouses and covered industrial spaces. Filtered water is pressurized and distributed through high-pressure misting lines to fine atomizing nozzles.
The unit typically operates at 50–70 bar and produces droplets of approximately 5–15 μm, depending on nozzle type and operating conditions. Pump flow, motor capacity and nozzle quantity are selected from the required cooling zones, water supply and installation layout.

Cooling System Selection
Cooling Area
The cooling area determines the number of active zones and the required misting-line layout. Production sections, warehouse aisles and loading areas can be configured as separate operating zones.
Pump Flow
Pump flow is calculated from the combined flow rate of the nozzles operating at the same time. The selected pump must provide the required flow at the specified operating pressure.
Nozzle Quantity
Nozzle quantity is determined by individual nozzle flow, installation spacing and the size of each cooling zone. The total nozzle demand forms the basis for pump sizing.
Water Supply
Available inlet flow, water pressure and water quality are reviewed before equipment selection. Filtration is matched to the incoming water condition and nozzle requirements.
Typical Applications
Workshops
Misting can serve defined production and working areas where localized evaporative cooling is required. Zone arrangement follows the workshop layout and operating areas.
01
Warehouses
Misting lines can be installed along storage, picking and material-handling areas. Individual zones allow cooling demand to follow the actual working layout.
02
Loading Areas
Covered loading docks and transfer areas can use localized misting around active work zones. Nozzle locations are selected according to installation height and available airflow.
03
Greenhouses
Fine water droplets provide evaporative cooling for greenhouse areas. Nozzle spacing, flow and operating intervals can be matched to the required environmental conditions.
04
Semi-Open Spaces
Covered industrial areas and logistics shelters can use high-pressure misting where natural airflow supports evaporation and distribution of cooled air.
05
System Configuration
Pump Unit: The pump assembly raises filtered water to the selected operating pressure and supplies the required flow to the misting network. Pump capacity is matched to the total active nozzle demand.
Filtration: The filtration stage removes particles from the incoming water before high-pressure delivery. Filter selection is based on water quality, nozzle requirements and expected operating conditions.
Misting Lines: High-pressure lines transfer water from the pump unit to each cooling zone. Line sizing and routing are selected according to flow demand, line length and zone arrangement.
Atomizing Nozzles: Nozzle orifice size and flow rate determine water consumption and atomization characteristics. Nozzle spacing is established from installation height and the required distribution pattern.
Cooling Performance Factors
Relative Humidity
Evaporative cooling depends on the moisture content of the surrounding air. Relative humidity is therefore an important input when assessing cooling conditions and system capacity.
Air Movement
Air movement supports evaporation and distributes cooled air within the treated area. Existing ventilation and natural airflow should be considered during nozzle placement.
Water Flow
Water consumption depends on individual nozzle flow and the number of active nozzles. Zone control allows the operating flow to correspond with the areas requiring cooling.
Installation Height
Nozzle height affects spray distribution and evaporation distance. The mounting structure and available installation height should be considered during system layout.
Manufacturing & Inspection
Component Assembly: Pump, filtration, control and high-pressure connection assemblies are configured according to the selected system specification. Each connection is matched to the corresponding component and line requirement.
Pressure Verification: The assembled water circuit is checked under operating conditions to verify pressure stability and connection integrity throughout the high-pressure section.
Flow Matching: Pump capacity is checked against the calculated nozzle demand. This establishes the relationship between pump flow, operating pressure and the number of simultaneously operating nozzles.
Final Inspection: The completed unit is inspected for assembly condition, connection quality, filtration arrangement and operating performance before packing and shipment.
Installation & Maintenance
Installation
The pump unit is positioned according to the available water and electrical connections. High-pressure lines are routed to the defined cooling zones, with nozzle positions established from site layout and installation height.
Filter Service
Filter condition should be checked according to water quality and operating hours. Cleaning or replacement intervals are determined from actual operating conditions.
Nozzle Inspection
Nozzles should be checked for consistent water flow and physical condition during routine service. Inspection frequency depends on water quality and operating hours.
Pump Service
Pump pressure, operating condition and high-pressure connections should be inspected according to the equipment service schedule and operating environment.
Procurement Information
Site Data: Provide the cooling area, installation height, number of operating zones and preferred misting locations. A site layout or marked floor plan can be used to establish line routing and nozzle positions.
Utility Data: Water inlet pressure, available water flow, water quality and electrical supply are required for equipment sizing. These values directly affect pump, filtration and control configuration.
Operating Requirements: Expected operating hours, simultaneous cooling zones and control requirements should be confirmed before final selection. These conditions determine the required pump flow and system capacity.
Configuration Review: The final specification is established from the site conditions and utility data. Pump flow, motor capacity, nozzle quantity, filtration and misting-line configuration are then matched to the intended cooling zones.
FAQ
Q: What is the operating pressure?
A: The typical operating pressure is 50–70 bar. The final working pressure depends on the selected pump, nozzle specification and system configuration.
Q: What droplet size does the unit produce?
A: Typical droplets are approximately 5–15 μm. Actual droplet characteristics vary with nozzle type, operating pressure and water conditions.
Q: How is pump flow selected?
A: Pump flow is calculated from the combined flow rate of the nozzles operating simultaneously. The pump is then matched to the required pressure and total system demand.
Q: Can different cooling zones operate independently?
A: Yes. The misting network can be divided into separate zones, allowing individual areas to operate according to the required cooling schedule.
Q: What information is required for a quotation?
A: Cooling area, installation height, water supply, electrical supply, operating zones, expected operating hours and preferred nozzle locations provide the main information required for system configuration.
