Product Description

Modulating actuators enable flow rate changes, and consequently heat output changes, to quickly match demand requirements, therefore, modulating actuators should be chosen for forced convection terminal units. Modulating actuators allow all intermediate flow rates between full flow and no flow.

Product Features

  • Natural convection (passive) terminal units, i.e. passive Chilled Beams and underfloor heating are designed to be less responsive to changes in room temperature than forced convection terminal units
  • On/off actuators only allow for full flow or no flow
