42TD/MD

District Cooling Chilled-Water Low-Height Fan Coil

300 to 2,000 nominal cfm

The 42TD/MD district cooling low height chilled water fan coil units are available in airflow range from 300 cfm to 2000 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.

42TD 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.

42MD 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.
