Evaporative Peds & Other Equipments
The reason to use Timfog Evaporative Pads & Other Equipments (referring to the complete Pad-and-Fan system) is to achieve high-capacity, low-energy cooling and humidification, particularly essential in regions with hot and dry climates where traditional ventilation is insufficient.
1.Highly Efficient Evaporative Cooling
Adiabatic Principle: The system works on the principle of adiabatic cooling. The exhaust fans (like the TEF-140) draw hot, dry outside air through saturated cellulose or plastic pads (the "peds").
Heat Transfer: As the water in the pads evaporates, it draws the necessary latent heat from the incoming air, causing the air temperature to drop significantly—often by -5 to -10 or more.
Cost-Effective Cooling: This method consumes significantly less electrical energy than mechanical refrigeration or air conditioning, making it the most economical solution for major temperature reduction in arid zones.
2.Optimized Pad Performance and Durability
High Saturation Efficiency: Timfog selects pads designed for maximum surface area and structural integrity, ensuring high saturation efficiency (i.e., maximum temperature drop for a given air flow).
Controlled Water Management: The "Other Equipments" include the sump, water distribution lines, recirculation pumps, and float valves. Timfog engineers this complete loop to ensure uniform saturation across the entire pad surface and manage water quality to prevent mineral buildup (scaling) on the pads, which maintains cooling efficiency and extends pad life.
3.Integrated Climate Strategy
Humidity Boost: Beyond cooling, the system provides essential humidification to the incoming dry air, helping growers maintain the optimal Vapor Pressure Deficit (VPD) for crop transpiration and preventing plant desiccation in very dry climates.
Complementary Cooling: The Pad-and-Fan system works synergistically with the exhaust fans and can be used in combination with fogging systems (for additional control or higher-humidity environments) or heating systems (used only when the fan system is off) to provide a complete, managed climate strategy.
In summary, Timfog's Evaporative Pads and associated equipment provide a robust, low-cost, and high-efficiency solution for simultaneously cooling and humidifying large greenhouse volumes, making year-round cultivation possible in challenging, hot, and dry climates.
