VT-1C Desert Air cooler in Dubai, UAE for Outdoor.

In this article lets review VT-1C desert cooler which is offered by CtrlTech in Middle East countries. VT-1C desert air cooler is most suitable for industrial environment conditions. It is best air cooler if we compare cost vs air flow with respect to all other outdoor cooler available in market. This cooler is suitable to use not only in industrial application but large public places like outdoor restaurants, marriage hall, party lawn, outdoor pool area etc.

Working Principle of VT-1C Desert cooler.

VT-1c Desert cooler for oudoor use works on evaporative principleVT-1c desert cooling unit consist of three major parts; which is fan motor, water pump and cooling pad. Fan motor is responsible to rotate fan to suck air through wet cooling pad and through it front side. Water pump is responsible to pump water on cooling pad continuously so that it will always wet condition. Cooling pad maintain moisture so that when fan sucks air through it, air should be get cooled.

When you start unit, first water pump will start which will pump water from water tank to top of cooling pad. This pumped water discharges at top of pad and hence it make pad wet. Pump continuously pumps water and keep cooling pad wet. After delay of two minutes fan motor will start. This fan motor sucks air through wet cooling pad. When air passes through cooling pad, due to evaporation temperature of air drops and cold air thrown front site.

Water pump transport the water from water tank to the water distribution and cooling pad at the same time. Air goes through the cooling pad, water evaporation dry away the surrounding heat and caused the drop in temperature of air. The water continuously wetting the cooling pad surface, the wind evenly through the cooling pad, absorbing heat from the air, transforming into cool air.

Features of VT-1C Outdoor Desert cooler.

VT-1C desert cooler has air flow of 22000 cubic meter per hour.  Unit is provided with strong lockable four wheels. Hence this unit easy move. Cooling pad has large surface area and hence cools large amount of air same time. Extra net mesh provided on cooling pad to protect pad from duct. This net mesh is removable and washable. At bottom of this desert air cooler, a water tank of 100 liter is provided. Water can be added in unit manually. Unit also has facility to connect direct connection of tap water to this tank. Floating valve is provide in unit which will cut off supply of water when tank is full. Fan motor is very powerful of 1100 watt capacity. Fan of VT-1C desert cooler is 30 inch size which can generates 22000 cmh air flow.  Unit has LCD display control panel. This panel shows working condition of air cooler. If tank has low water then then this LCD display will show low water level indication. Pump of this outdoor cooler can be switch on or off on demand to use this unit as fan if required. Panel has fan speed button with which unit can be set into low, medium or high speed model. This desert cooler design has swing function for front window. Swing option can be switch on or off from panel.

Applications of VT-1C Desert air cooler.

Applications of VT-1C desert air cooler are as follow:

Manufacturing Industry: Mechanical manufacturing, Ceramic, Metal, Textile industry, Foundry industry, Injection molding industry etc.

Processing Industry: Mechanical processing, Electronic processing, Printing processing, Rubber, Food processing, Tobacco and Floor industry.

Other Applications: Staff dormitory, office, Schools, Hospitals, Waiting rooms, Entertainment, Supermarket, restaurants, Bakery, Kitchen, Golf Course, Living room, Housekeeping, Laboratory, Guesthouse etc.

Evaporative Industrial Outdoor desert air cooler.

VT-48 desert air cooler in DubaiIn this article we will try to understand basics of air cooler which commonly called as desert cooler. Evaporative coolers are economical way of cooling. It is commonly use in large areas like factory, bus stop, lawn, hospital, marriage hall etc. It has many advantages over air conditioning unit. In this article we will try to understand different parts of desert cooler and functions of each part. Also we will try to understand working of evaporative cooler.


Working principle of an evaporative portable air coolers is simple. It consisting you Fan, Fan motor, Cooling Pad, Pump and controller. Fan is attached directly to motor which sucks air through cooling pad. Pump continuously drops water at top of cooling pad so that cooling pad always wet and water film get form at cooling pad. Controller controls motor and fan. From controller one can switch on/off air cooler, set speed, switch on/off pump, set timer etc.

how desert cooler workWorking: When you switch on air cooler, fan motor start rotating and so as fan. Fan sucks air from back side which passes through wet pad. As mentioned before pump continually pours water on tope of pad due to which pad get wet and water film get formed at pad. Hot Air passing though wet pad get in touch with water in pad and looses it’s thermal energy instantly which leads to drop in temperature of hot air and cold air get pushed by fan. In many desert cooler design in steady of cooling pad desert cool rediators are get use. To reduce temperature of air from desert cooling system, two pads are get use in some designs which called as Two stage Evaporative cooler.

Advantages of Evaporative Desert cooler.

As mentioned before evaporative type desert air cooler has many advantages. Major advantages as follow:

  • Low Running cost: Evaporative air cooler has 90% less operating cost than that of traditional refrigerant air conditioner.
  • Low Electricity Power requirement: Desert air cooler take low power than air conditioner.
  • Lower Peak Energy Requirement: Evaporative coolers has lower peak energy requirement which will give benefit of low cost wiring and these cooler can be use with solar energy also.
  • Desert cooler air conditioning has low maintenance cost than refrigerant type air conditioner.
  • Portable evaporative air coolers are more environment friendly than refrigerant type of air conditioner.
