42TW/MW
Chilled-Water Low-Height Fan Coil
300 to 2,000 nominal cfm
The 42TW/MW standard cooling low height chilled water fan coil units are available in airflow range from 300 cfm to 2,000 cfm. All series are available with a 3 or 4 row coil.
Each unit is designed to occupy a minimum space. Piping and drain connections are readily accessible and mounting holes and slots are pre-drilled to save installation time and field labor expense.
42TW Series are available in 8 sizes designed for medium external static pressure up to 0.25 inches water (63 Pa) in low false ceiling applications with nominal cooling capacity from 12 to 60 KBtu/Hr.
42MW Series are available in 2 sizes designed for high external static pressure up to 0.5 inches water (125 Pa) in low false ceiling applications with nominal cooling capacity from 48 to 60 KBtu/Hr.
