COIL – PT/4

  • for heating dry interiors
  • identical in dimension to convectors PT, PO but it has a higher output Q
  • supplied with thermostatic head as standard

DIMENSIONS

total width
303 mm
construction height
125 mm
length
900 - 3000 mm

USAGE

COIL PT/4 is recommended for individual use in interiors where COIL PT does not efficiently cover the heat requirement. COIL PT/4 can be also combined with COIL KT and MT, which have a significantly higher heat output.
