Saunders P345 Pneumatic Actuator UK & Ireland

Saunders P345 Pneumatic Actuator

The Saunders® P345 Polymer Pneumatic Actuator is designed to reduce operating pressure requirements to 4.5 bar, which can reduce your carbon footprint and energy costs by 11% (see below for details). The lightweight piston-type pneumatic actuator has been developed to deliver sustainable performance for Sterile Biopharmaceutical applications. The piston-type actuator permits remote operation of the valve, either as an alternative to manual operation or as an integral part of a control system.

The P345 housing is manufactured from a hybrid construction of polished 316 Stainless Steel and glass-filled Polyamide, producing a robust design, a clean OD profile, and an attractive appearance. It can withstand typical industry washdown regimes.

Saunders® P345 Actuator Data Sheet

Energy Savings

Comparison savings when using a P345 Saunders HC4 pneumatic actuator.

Note: The following comparison / savings is based on a compressor system running at a typical 6 barG supply.

Note: This is currently the common supply an actuator requires) and by comparison a compressor system using the P345 Saunders actuator requires only 4.5 barG supply and therefore the following energy savings can be expected. Based on over 50 energy assessments of mid-sized industries, we found that the average unit energy cost of compressed air ranges from about $0.15 to $0.35 per thousand standard cubic feet and frequently comprises between 5% to 20% of a plant’s annual electric costs

A 6 bar supply compressor system = 111.85 Kw power.
Using a P345 Saunders actuator, requires a 4.5 Bar supply, providing the user with a 11% power saving, reducing the power to 99.68 Kw.
Using the same comparison (6 Bar vs 4.5 Bar) Kw per year on a 6 Bar system = 979,806 Kw/year vs 873,223 Kw/year, proving the user with a 106,583 Kw/year reduction/saving.
At a cost of $0.35 kWh the Saunder P345 actuator provides a $37,304 monetary saving on power consumption.
The CO2 Emissions reduced by 14,380 per year CO2 kg per Kw.
This saving is the equivalent of planting 14 new trees (A typical tree absorbs 21 CO2 kg/year).
