Explosion-proof fan coil unit applicable locations:

Suitable for Class II, Groups A, B, C explosive gas environments.

2. Suitable for environments with temperature categories T1 to T5.

3. Suitable for flammable and explosive hazardous areas such as extraction, storage, battery manufacturing, warehousing, and refining, particularly for small chemical warehouses, storage facilities, and spaces with limited space.

Explosion-proof ceiling fan coil product features:

The indoor unit features a low-noise design, with thermal insulation and soundproofing materials attached to the inner wall. The indoor fan utilizes a high-quality, efficient centrifugal fan, providing you with a quieter experience.

Energy-saving operation setting function allows the minimum temperature (cooling) and maximum temperature (heating) for a room to be set on the hand-held controller. For instance, if the cooling minimum is set to 25°C, other operators will only be able to set the room temperature above 25°C, preventing waste due to incorrect operation.

Utilizing high-quality compressors, the latest hydrophilic membrane aluminum foil, efficient internally threaded copper tubes, and motors, combined with meticulous system design, the unit boasts superior performance and reliable operation.

Indoor explosion-proof fan coil units (explosion-proof duct fans) and supply/return air ducts are installed within the ceiling, creating a harmonious layout and an elegant production environment for explosion-proof central air conditioning systems, where one can fully enjoy the refined taste.

Remotely controllable from a distance, with power failure memory, weekly scheduling, and fault self-diagnosis capabilities.

Field installation requirements: Explosion-proof fan pipe units (explosion-proof duct fans) can flexibly determine the air supply and return patterns (bottom return or rear return), as well as the condensate discharge direction (left-hand or right-hand). Moreover, they can be matched with various air outlet types to meet your design requirements.

Design and manufacturing of explosion-proof fan pipe sets (explosion-proof duct fans) strictly adhere to national standards.
