Acme Fans
Acme Fans are the highest quality, most efficient, long running, lowest maintenance, strongest and best greenhouse, agricultural and industrial fans in the world.
Demand for industrial ventilation fans and evaporative pad cooling systems continues to grow worldwide as businesses seek efficient and cost-effective solutions for temperature control and air circulation. These systems are especially valuable in garment factories, manufacturing facilities, warehouses, product storage buildings, greenhouses, and agricultural structures.
Effective greenhouse and agricultural building ventilation is essential for maintaining optimal temperatures and creating a suitable environment for plant growth. Solar radiation is the primary source of heat inside greenhouses, often causing indoor temperatures to rise above desired levels.
To control excessive heat, hot air must be continuously removed and replaced with fresh air. Properly designed greenhouse ventilation systems use exhaust fans to remove accumulated heat, while evaporative cooling pads help lower incoming air temperatures through the natural process of water evaporation.
Industrial Fans and Evaporative Cooling Systems for Greenhouses, Poultry, Swine, Dairy, Factories & Warehouses
Selecting the right industrial fans and evaporative cooling equipment depends on several factors, including building dimensions, floor area, ventilation requirements, and desired temperature reduction.
This brochure provides a simplified guide to calculating greenhouse ventilation requirements and selecting the appropriate exhaust fans and evaporative cooling pad systems for efficient temperature management.
Whether you need cooling solutions for a greenhouse, agricultural building, factory, or warehouse, USGR and Acme offers ventilation and evaporative cooling solutions designed to improve airflow, manage heat, and create more comfortable indoor environments.
