VT-28 Evaporative Cooling System.

Evaporative Cooling System.

There are direct and indirect evaporative cooling methods. The Evaporative cooling system is the most effective and low-cost cooling method. In general, these units consist of a cooling pad or heat exchanger and a fan. Air loosed its temperature when a fan draws the air from a moist pad. VT-28 can cool 14000 cubic meters per hour of cold air. Through the user panel, users can set cooling fan speed.

VT-28 evaporative cooling fan.

VT-28 evaporative cooling fan works on the direct evaporative cooling principle. Thus, the quality of the heat exchanger, which is a paper pad, is the most important. VT-28 uses a high-quality, thick, durable pad with a fan motor and a pump. The body casing of this cooler is made up of durable plastic, which makes it light and elegant. A large tank of this desert cooler is well enough to run the unit for at least 6 hours. Also, this unit is silent with options of different fan speeds. the auto water connector.

VT-28 uses a single-stage evaporative cooling method. But on-demand, we can supply a customized two-stage evaporative cooler. VT-28 is easy to clean with a discharge knob at its bottom. The swing motor fitted on the front grill helps to air 180 degrees. The water pump gets switched off when water gets low.

FAQs of evaporative cooling system.

This method used primary and secondary air streams. The indirect evaporative cooling process consists of a secondary heat exchanger, preventing direct air contact with the moist surface. Secondary air goes through the cooling pad, cools primary air, and removes some moisture. Thus, this method delivers low humid air.

What is indirect evaporative cooling?

Inside a direct evaporative cooler, the air is sucked through the wet cooling pad. In other words, air directly gets in touch with the moist surface for evaporation. As a result, it delivers cold but humid air into the room. This method is unsuitable for equipment rooms where machines can get corrosion due to moist air.

What is direct evaporative cooling?

UV sterilization lamps can kill bacteria present in the water. Water is supplied to the

  1. The direct evaporative cooling generated cold but humid air. The indirect method generates cold but dry air.
  2. The indirect evaporative coolers are expensive, and it needs more power.
  3. Direct cooling machines can cause the corrosion of metals.
  4. Indirect coolers are suitable to use even in a room with inadequate ventilation.
  5. Indirect evaporative cooling is more expensive than direct cooling machines.

Both direct and indirection cooling systems are available with single and multi-stage cooling. As the name suggests, a single-stage evaporative cooler has only one heat exchanger. In contrast, a multi-stage system has several heat exchangers. Multi-stage evaporative cooling generates excess cold air, but it is expensive.

VT-21 is a first-rate evaporative cooling system with top-grade components. It has a silent operation and a small footprint. Thus, it is suitable for public areas like restaurants. The Control panel is located at the top of the unit. VT-28 is a direct evaporative cooling model. It can deliver up to 14000 CMH of cold air and is suitable for a space of 1615 square feet. Along with the 60 liters tank, it has a hose connection knob. Adiabatic evaporative cooling units are recommended to avoid foul odor. But, it is recommended for areas where we need to maintain low temperature and humidity. Indirect evaporative cooling systems are more expensive. VT-28 has a more oversized evaporative cooling pad, which processes large amounts of air. This outdoor cooler is used in gardens, supermarkets, restaurants, RV parks, exhibition halls, etc. CtrlTech offers evaporative air coolers of different capacities in Dubai, Abu Dhabi, Sharjah, Al Ain, Ras Al Khaima, Al Fujairah, and Umm Al Quwain. Amongst all cooling methods, the evaporative cooling cost is minimal.
