Evaporation Cooling Unit
The Heart of HVAC Systems

Single-Stage Evaporative Cooling Unit (Air Washer)

A Single-Stage Evaporative Cooling Unit, commonly referred to as an Air Washer, is a highly efficient and environmentally friendly system that leverages the natural process of water evaporation to cool and ventilate air. Ideal for industrial plants, warehouses, workshops, and commercial settings, this system delivers high volumes of fresh air with low energy input and no chemical refrigerants.

Designed for maximum cooling performance and long-term reliability, our air washers feature rugged construction, smart water distribution, and low-maintenance operation. With airflow capacities ranging from 2,000 to 180,000 CFM, they are suitable for a wide range of applications requiring dependable, sustainable cooling.

Supports sustainable design and green building initiatives.

Double-Stage Evaporative Cooling Unit (Air Washer)

Our Double-Stage Evaporative Cooling Unit is an advanced, energy-efficient air cooling solution that combines both indirect and direct evaporative processes. Designed for large industrial and commercial spaces, this system delivers lower temperatures with better humidity control—offering superior performance over traditional and single-stage cooling units.

With no refrigerants or compressors involved, it ensures eco-friendly operation and minimal energy consumption. The unit is built for durability and high airflow, making it ideal for facilities requiring consistent thermal comfort, even in moderately humid climates.

Key Features

Two-Stage Cooling Process

Stage 1 - Indirect Cooling: Air is first cooled via a heat exchanger without adding moisture, keeping humidity in check.
Stage 2 - Direct Cooling: Pre-cooled air then passes through wetted cellulose pads for further temperature reduction.
Enables more precise control of air conditions compared to single-stage systems.

Superior Cooling Efficiency

Achieves higher temperature drops (up to 12–18°C) depending on ambient conditions.
Provides enhanced thermal comfort with lower indoor humidity.
Ideal for areas with moderately humid climates where conventional systems underperform.

Energy Saving & Eco-Friendly

Functions without refrigerants or compressors—just water and air.
Consumes significantly less power than traditional HVAC systems.
Supports sustainable, low-carbon cooling for green buildings.

Durable Construction

Built with galvanized or powder-coated steel for corrosion resistance.
Optional double-skin panels with PUF or rockwool insulation for enhanced thermal and acoustic performance.
Modular and scalable design simplifies installation and future expansion.
