Constant Temperature And Humidity AHU For Hospital

Product series which we can do:

1. Constant temperature and humidity type unit
2. Clean room constant temperature and humidity unit
3. Heating and cooling heat pump type unit (including fresh air type)
4. Heating and cooling type unit (including fresh air type)
5. Single cooling unit (including fresh air type)
6. Multifunctional unit
7. Double cold source deep dehumidification unit
8. Double cold source fast cooling air conditioning unit

Application:

Purification engineering: including electronic information, semiconductors, optoelectronics, precision manufacturing, medicine and health, biological engineering, aerospace, automotive spraying and many other industries

Advantage of direct expansion air handling units:

No water system, no secondary heat exchange, no large computer room and control, simple installation and construction

The difference with other air conditioning units:

1. Good sealing, heat preservation and pressure bearing performance (low air leakage rate, low deformation rate, no cold bridge);
2. Avoid secondary pollution (dry water tray, hydrophilic membrane surface cooler, no belt dust, no bacteria breeding)
3. Adjustable air volume (fan motor frequency conversion);
4. High filtration level (primary, middle and sub-high efficiency);
5. Complex functional sections (filtration, cooling, heating, dehumidification, humidification, noise reduction, disinfection);
6. The front wind speed should not be too high;
7. Centralized control is required (reserved information panel interface).
