Pilot valve
Pilot valves are often used in larger refrigeration plants with many consumers. A pilot valve is an add-on to the in-line valve. It enables a small force to operate the larger valve like in a hydraulic piston.
Plate heat exchanger
A plate heat exchanger is a heat exchanger that is used to transfer heat from one fluid to another.
Pressure is used to circulate liquid in a heating or cooling system and is induced by means of pumps. The pressure in a system is positive in relation to atmospheric pressure.
Pressure boosting system
A pressure boosting system is designed to increase low pressure in a water system in order to achieve sufficient water flow and pressure to consumers.
Pressure reducing valve
A pressure reducing valve measures the pressure of the discharge side of the valve. Its task is to hold the set pressure constant.
Pressure transducer
A pressure transducer is fitted in a heating-, cooling-, or ventilation system. It measures the pressure in a specific location in a system and converts it into a signal which can be read by an instrument.
Pressure transmitter
Measuring and transmitting pressure plays a key role in system monitoring and controlling pumps/fans in order to achieve a required pressure at any given time
PROFIBUS is a network technology mostly used in process industries but you can find it also in building automation. It is a standardised technology for data communication, managed by Profi International.
PT 100 sensor
A PT 100 sensor is a temperature sensor which works by measuring electrical resistance through platinum (Pt) metal. A PT 100 sensor can measure temperatures up to 600 °C
PUR foam
PUR foam is used for insulation of almost all cooling pipes and cooling installations due to its impermeablity and is therefore used extensively in the production of insulation jackets for pipes, fittings, etc.
