The Warehouse Cooling Fog Unit is a packaged high-pressure water mist system for evaporative cooling in distribution centers, logistics warehouses, loading docks, and semi-open storage areas. It filters incoming water, raises pressure through an industrial pump, and supplies controlled water flow to high-pressure misting lines and atomizing nozzles.


The unit operates at 50–70 bar and produces fine droplets of approximately 5–15 μm. Cooling performance depends on ambient temperature, relative humidity, airflow, nozzle selection, and system flow. Pump capacity, motor power, nozzle quantity, and cooling zones are configured according to the warehouse layout, operating requirements, water supply, and available electrical power.

Cooling Method

 

Fine Water Atomization
The high-pressure pump supplies water to precision atomizing nozzles. Pressure and nozzle geometry divide the water into fine droplets, increasing the exposed water surface and supporting rapid evaporation when temperature, humidity, and airflow conditions are suitable.


Zoned Cooling Architecture
The misting network is divided into independent cooling zones based on warehouse activity and layout. Operators can activate selected areas according to working schedules, helping direct cooling capacity toward occupied or heat-intensive sections.


Calculated Flow Regulation
Water demand is based on the quantity and flow rate of active nozzles. Pump and control settings are matched to the required operating flow and pressure so each configured zone receives the designed water supply.

 

Warehouse Applications

 

Storage Area Conditioning
Overhead misting lines can be installed along defined storage sections. Nozzle spacing and mounting positions are selected according to ceiling height, rack arrangement, airflow, and the required cooling coverage.


Loading Dock Operations
Loading and unloading areas can be configured as separate cooling zones. Independent zone control allows mist output to follow operating schedules and the areas in active use.


High-Roof Facility Coverage
Warehouses with high ceilings can use elevated misting lines positioned according to roof structure and floor layout. Pipeline routing and nozzle placement are designed to distribute mist across the specified cooling area.


Semi-Open Storage Management
Covered storage areas and naturally ventilated spaces can use evaporative mist cooling where airflow supports water evaporation. System layout is adapted to the level of environmental exposure and local operating conditions.

 

Configuration Selection

 

Pump Flow Sizing
Required pump flow is calculated from the combined water demand of the nozzles operating at the same time. Pipeline length, fittings, elevation, and hydraulic losses are included in the system calculation.


Operating Pressure Matching
The working pressure range is 50–70 bar. Pressure selection is matched with nozzle flow characteristics and the hydraulic design of each cooling circuit.


Motor Capacity Selection
Motor capacity is selected according to pump flow, working pressure, and electrical supply. Available configurations range from 1.5 to 7.5 kW for different hydraulic requirements.


Nozzle Quantity Determination
Nozzle quantity is determined from cooling area, ceiling height, spacing, zone arrangement, and individual nozzle flow. Placement is based on the actual warehouse layout rather than floor area alone.

 

Water and Filtration Requirements

Water Quality Standards

The high-pressure circuit uses filtered clean water. Source water quality is reviewed during system selection to establish suitable filtration and protect the pump, piping, valves, and nozzles.

Multi-Stage Filtration

Inlet filtration removes suspended particles before water enters the high-pressure circuit. Filter selection is based on source water conditions, required flow, and nozzle specifications.

Water Supply Parameters

Available inlet pressure, supply flow, connection size, and water source characteristics are confirmed before production. These values are used to match the pump and inlet piping configuration.

 

Installation and Control

 

Pipeline Network Connection
The pump unit connects to dedicated high-pressure misting lines leading to the atomizing nozzles. Pipeline routes follow the warehouse plan, cooling zones, mounting positions, and required service access.


Multi-Zone Valve Control
Multiple cooling circuits can be connected to one pump unit when the combined nozzle demand remains within the selected pump capacity. Zone valves regulate water delivery to individual sections.


Automated System Control
Control panels can support scheduled start and stop functions, programmable operating cycles, and zone switching. Control logic is configured according to warehouse working hours and cooling requirements.

 

Manufacturing and Inspection

 
 

Skid Assembly Integration

The packaged unit integrates the high-pressure pump, motor, filtration components, pressure regulation components, and electrical controls on a structural frame for organized installation and service access.

 
 
 

Comprehensive Functional Testing

Before shipment, the assembled unit is checked for operating pressure, water flow, control response, and hydraulic connection integrity under defined test conditions.

 
 
 

Configuration Verification

Final inspection confirms that pump flow, motor capacity, filtration arrangement, pressure settings, and control configuration correspond with the approved technical requirements.

 

 

Procurement Information

Frequently Asked Questions

 

Q: What pressure does the Warehouse Cooling Fog Unit operate at?

A: The standard operating pressure is 50–70 bar. Final working pressure is selected according to nozzle flow characteristics and the hydraulic design.

Q: How is total pump flow determined?

A: Pump flow is calculated from the combined water demand of all nozzles operating simultaneously within the selected cooling zones, with hydraulic losses included in the system calculation.

Q: Can a single pump unit supply multiple warehouse zones?

A: Yes. One pump unit can serve multiple independent zones when total nozzle demand, pipeline design, pump capacity, and zone valve configuration are properly matched.

Q: What water supply parameters are required?

A: The system requires filtered clean water. Inlet pressure, available flow, connection size, and source water characteristics should be confirmed during system selection.

Q: What information is required for a formal quotation?

A: Provide warehouse drawings, cooling areas, ceiling heights, zone requirements, nozzle information, water supply data, electrical specifications, pipeline requirements, and preferred control method.
