Industrial Evaporative Air Cooler High Efficiency Large Airflow Durable

The Huachi industrial evaporative air cooler, also known as a water-cooled air conditioner, delivers the most energy-efficient space cooling available today. Using the natural process of water evaporation, a single 1.1 kW unit generates an astonishing 24.82 kW of cooling capacity — equivalent to a 10-ton conventional air conditioner — with an unmatched energy efficiency ratio of 21.75 kW/kW, certified by China’s National Compressor and Refrigeration Equipment Quality Inspection Center.

Designed for the extreme heat of Southeast Asia and the Middle East, our coolers force large volumes of fresh, chilled air across your facility, achieving whole-room, zone, or spot cooling through ducting up to 30 meters. The core is a 5090 high-efficiency evaporative cooling pad with superior water absorption and over 90% evaporative efficiency, removing PM10 dust by 90%+. The housing uses UV-stabilized PP modified engineering plastic or stainless steel, ensuring decades of corrosion-free life. Equipped with a fully enclosed pure copper IP55 motor, a twelve-speed intelligent controller, and automatic cleaning and water-shortage protection, this unit provides set-and-forget cooling at a fraction of the energy cost of traditional air conditioning.

Across factories, warehouses, commercial kitchens, and agricultural sheds in hot climates, four problems make traditional cooling impossible:

• Prohibitive air conditioning costs: Compressor-based AC for large, open, or semi-open spaces demands enormous electrical infrastructure and generates unpayable monthly bills.
• Ineffective fans: High-speed fans simply move hot air around, offering no temperature reduction and often stirring up dust.
• Heat stress and low productivity: Workers and livestock suffer in still, 40°C+ heat, leading to health risks, lower output, and increased mortality in poultry and livestock.
• Dry, dusty air: In the Middle East and parts of South Asia, the air is not only hot but painfully dry and dust-laden, causing respiratory problems and equipment wear.

The missing element is affordable, large-volume cooled fresh air that can be directed exactly where it is needed.

Huachi evaporative coolers solve these problems by pulling hot outside air through a continuously saturated cooling pad. As water evaporates, it absorbs an immense amount of heat, dropping the air temperature by 4–10°C and delivering it as a powerful, fresh breeze. This cools people, equipment, and animals, while also humidifying and filtering the air — a triple benefit no AC or fan can match.

• Certified ultra-efficiency: The 1.1 kW motor produces 24.82 kW of cooling, meaning you can ventilate and cool an entire workshop for the cost of running a small household appliance.
• Advanced 5090 cooling pad: High-density, odor-free cellulose media with minimal air leakage (10–20% less than inferior pads) and 90%+ PM10 dust removal delivers cleaner, cooler air that can lower effective temperatures by an extra 1–2°C.
• Multi-mode intelligent controller: A full-function LCD panel or remote provides 12 fan speeds, forward supply and reverse exhaust modes, pre-cool wetting, automatic post-shutdown drying, and a 1–99 hour self-cleaning cycle. Water pump dry-run protection eliminates fire risk.
• Built for harsh climates: The premium PP engineering plastic housing is impregnated with anti-UV and anti-aging masterbatch to withstand relentless sun. The IP55, F-class insulated motor operates reliably from -20°C to 60°C, and optional stainless steel bodies offer additional durability for corrosive environments.
• Flexible cooling strategies: From flooding an entire factory floor with cool air, to ducting spot-cooling to specific workstations up to 30 meters away, our coolers adapt to your layout.

*Custom frequencies (e.g., 60Hz) and voltages available upon request. All models include: IP55 pure copper motor, 5090 high-efficiency cooling pad, integrated dust filter mesh, fully framed pad with black-blue aesthetic finish, automatic cleaning, and multi-function intelligent controller (12 speeds, remote, water shortage protection).

• Heavy industry: injection molding, die-casting, metalworking, printing plants.
• Light manufacturing: garment and textile factories (benefits from added humidity), electronics assembly, footwear.
• Commercial & public: large restaurants and canteens, gymnasiums, exhibition tents, supermarket warehouses, bus stations.
• Agriculture: poultry and swine barns, greenhouses (cooling and humidification), dairy holding areas.
• Spot cooling: assembly line workstations, loading docks, and any high-heat point up to 30 m from the unit via flexible ducting.

1. Hot, dry air intake: A powerful axial fan pulls outside air through a dust filter and then through the honeycomb-structured 5090 cooling pad, which is kept constantly saturated by a water pump from the internal tank.
2. Adiabatic cooling: As the air passes through the wet pad, water evaporates into it, absorbing a huge amount of latent heat. The air temperature drops sharply (by 4–10°C depending on ambient humidity) while its moisture content increases.
3. Clean, cooled air delivery: The now-cool, filtered, humidified air is blown out through the front grille or connected ductwork directly into the occupied zone.
4. Continuous exchange: The positive pressure pushes hot, stale air out of open doors, windows, or exhaust fans, maintaining a constant flow of fresh, cooled replacement air. The intelligent controller automates the entire cycle, including water replenishment and pad drying to prevent mold.

• Whole-room cooling: For open workshops and halls, simply replace the room’s air volume 20–30 times per hour with cooled air.
• Spot cooling: For workstation cooling, one 20,000 m³/h unit can typically serve 4–8 personnel via ducting.

Required Airflow (m³/h) = Room Volume (m²) × Ceiling Height (m) × Air Changes (typically 25–30 for factories)
Example: A 500 m² × 4 m workshop needs 500 × 4 × 25 = 50,000 m³/h. Two KWY-KT-30K units (60,000 m³/h total) or one KWY-KT-40K plus a smaller unit would be ideal.

• Standard: PP modified plastic for durability, UV resistance, and value.
• Corrosive or ultra-harsh environments: Stainless steel models (25K/30K/40K).

We can supply 220V single-phase or 380V three-phase units, 50Hz or 60Hz. Contact us with your power specifications for the correct configuration.

In hot, dry climates typical of the Middle East and inland areas, the outlet air can be 8–10°C cooler than the outside air. In more humid tropical conditions (e.g., coastal Southeast Asia), expect a 4–6°C drop, with the added benefit of a massive cooling breeze that makes it feel significantly cooler on the skin.

No, the cooler is designed for open or well-ventilated spaces. The slight increase in humidity is continuously exhausted along with the hot air. In textile mills and greenhouses, the added moisture is an advantage, reducing static electricity and plant stress. Our automatic post-run drying cycle also prevents moisture build-up inside the unit.

With the built-in automatic 1–99 hour cleaning cycle and use of clean water, the 5090 pad typically lasts 3–5 years under continuous operation. It is easy to inspect via the side access panel, and replacement is simple. Regular flushing of the water tank is the only routine maintenance needed.

Yes, this is independently certified. The fan and water pump together consume 1.1 kW of electricity. The cooling effect comes not from a power-hungry compressor, but from the physical property of water absorbing heat as it evaporates. The energy efficiency ratio of 21.75 is precisely why this is the cheapest industrial cooling method to operate.

The intelligent controller has a water pump shortage protection function. If the water level drops below the safe point, the pump automatically stops to prevent dry-running and burnout. The fan can continue to operate as a ventilation fan until water is refilled. This eliminates any fire risk associated with a stalled pump.

Yes. All models can be fitted with distribution ducting up to 30 meters in length. We supply accessories for designing a system that drops cool air directly to individual workstations on an assembly line, maximizing comfort without cooling empty spaces.
