Speed controller for air-cooled condensers. The P216 is a pressure-controlled speed controller for air-cooled condensers. The controller reads pressure changes in the refrigerant circuit and modifies the motor speed depending on this pressure change. The pressure range of the speed controller is determined by a DIP switch setting. Not only does the P216 offer stable operation at all times of year, it also saves energy and reduces operating costs. The P499Vxx-405C pressure transducers are available in sturdy 17-4PH stainless steel. The pressure transducer head is made as a single piece and does not require any O-ring seals. Refrigerant losses at the transducer are therefore practically impossible. The pressure-side connection is made using a 7/16”-20 UNF inner thread incl. valve opener.
