Clean Energy Compression Corporations’ roots go back over 100 years to a Blacksmith’s shop in Chilliwack where Ironsides Machining & Welding was established in 1912.
Over decades of custom fabrication, Clean Energy Compression became an early adopter of compressed natural gas in 1984 and began building CNG fueling systems for station operators.
A sampling system is used to obtain a small product sample from a pipeline with the same proportions of oil, water, and contaminants as a running stream. OGSI supply sampling and analyzer skids that operate non-stop since fast loop sampling bypasses the main line. The sampling system is considered to be the most cost-effective solution in cases when analyzers are not required per project specifications. Check here to know more about sampling system.

On the road to green machines...how oem's can improve the energy efficiency o...Schneider Electric
While many OEMs are aware of new technologies to
make machines more energy-efficient, they are
reluctant to make changes due to the perception
that it will make their machines more expensive to
sell. The constraints of cost reduction, usage of
resources and energy reduction are becoming key
drivers in the industry as consumers require
manufacturers to be more “green”. This paper
demonstrates how incorporating sustainable
design can add value to their machines and
differentiate OEMs from the competition.
Technical overview of the research questions and findings as well as a discussion of targeted recommendations for utility energy efficiency programs and operator learning.

9. Green Solution in PCS - Introduction
Q. What is a Paint Circulation System ( PCS ) ?
A . A system that moves paints /coatings from a Can to the part
to be painted without attributing to any defect .
Pumping Module Pipe Network
Heat Exchanger System
Drop Point Station
10. Green Solution in PCS - Introduction
Flow – If the flow varies or is inadequate painting is affected.
Pressure – Low or High Pressure can affect Painting equipment and finish
quality.
Temperature – Out of range temperature cause paint defects.
Velocity – Paint movement below 60fpm cause shade variations and many
other defects.
Shear – Damages Paint pigments thereby affecting end result.
11. Green Solution in PCS - Introduction
Maintain uniform color and distribution of pigments, metallic and mica –
Maintain particle velocity 60 ft/ min +
Maintain uniform viscosity by maintaining proper circulation rate ( shear )
and temperature
Meet pressure and flow rate requirements of automatic and manual
stations
Maintain suspension which prevents settling of paint
Provide a low shear system design
Provide the best solution to meet all functional objectives with less energy
consumption thereby lowering cost of operation ( cost per unit produced )
12. Green Solution in PCS
What is the need for an intelligent fluid handling system?
Many organizations have a growing concern for the environment.
Businesses play a critical role in developing and utilizing environmentally
sound products.
Awareness of the impact fluid handling equipment can have on the
environment to find ways to reduce negative effects.
• Reduction of Energy
• Compliment with governmental regulations
• Customer demands for eco-friendly technology
• Protecting the environment
13. Green Solution in PCS
We needed to develop an intelligent fluid handling
system so it was a natural thought to create energy
saving simply by using less energy.

16. Green Solution in PCS
Now develop a fluid handling system, capable of…
…“Turning on and off the tap” self sufficient.
The patented SMART control:
”Tap OFF mode” - Open Loop
when paint needs to be circulated but is not required at any take off
point.
”Tap ON mode” - Closed Loop
when paint is required maintain required pressure but only supply the
flow needed at the user points
19. Green Solution in PCS - Differences
Typical Pulsation of most Paint systems after Surge suppression

20. Green Solution in PCS
Factors To Consider When Comparing Running Costs
Pneumatic Pump Operation Cost (Indirect Energy Source)
kW to Operate Air Compressor
kW to Operate Air Drier
kW lost due to pipework pressure drops and air leaks
High System Installation & Maintenance Costs
Air Motors may require Heaters to prevent freezing
Electric Pump Operation Cost (Direct Energy Source)
kW to Operate Electric Motor
Low System Installation & Maintenance Costs
21. Green Solution in PCS – Current

Ie. A typical Pneumatically driven PCS Pump requires 4x the
amount of power compared to a Smart Electrical Pump System
22. Green Solution in PCS
Smart Control
The ‘Smart’ system design provides for
two modes of operation.
Open Loop
Back Pressure Regulator „Unloaded‟ to
reduce the paint line pressure and
Pump pressure requirement
Pump motor will be driven to run at a
set minimum speed (Min Paint velocity)
Back Pressure
Regulator
(air pilot)
Closed Loop
Paint pressure maintained by the back-pressure regulator
Pressure sensor monitors System Pressure
Pump speed is controlled to maintain system pressure to the
pre set point value
