Direct Expansion Air Conditioning Unit

Our Direct Expansion Units work in a different way. They send refrigerant directly to the evaporator inside the unit. In winter, the same coil works as a condenser for heating. This replaces the need for a separate heating coil and cooling coil. The system includes several sections: return air, exhaust, mixing, primary filtration, evaporator (or condenser), spray humidification, secondary heating, supply fan, fine filtration, sterilization, and supply air. This design saves money. It removes the step of cooling water first and then pumping it to the unit. Yancheng Lima Air Conditioning Engineering Co., Ltd. has been innovating since 1996.

This unit is good for places that need clean or sterile air. Our Direct Expansion Units combine many functions in one system. They provide constant temperature, humidity, pressure, and clean air. The built-in sterilization section adds an extra layer of protection. This makes the unit a good fit for hospitals, labs, and pharmaceutical facilities. Our factory in Yancheng uses advanced equipment. We have laser cutters, bending machines, and automatic welding machines. We build each unit to meet high quality standards.

Traditional systems need extra parts. They require chillers, pumps, and piping. Our Direct Expansion Units simplify this. The refrigerant does the work directly. This means lower equipment costs. It also means lower operating costs. Installation is simpler too. You have fewer parts to set up. Our service team helps you from start to finish. We help with selection, installation, and maintenance. We have multiple patents and certifications. Our products are sold in 23 provinces and in countries like France and the USA. You can trust us for a smart, efficient solution.
