CASE: Innogas, Finland
Customer
OY Innogas, Finland (Porvoo plant)
The customer's challenge
Innogas needed a complete upgrade of their plant at Porvoo, taking into consideration the vast diversity of the cylinder types to be processed; 16 sizes ranging from 2 kg to 18,4 kg made from composite, aluminium and stainless steel using clip-on, hand wheel and FLT valves.
Our solution
We installed a main line with a 24 post filling carrousel to handle small and medium sized cylinders. All posts are equipped with dual filling heads to fill both top entry and side entry valves respectively incl. automatic valve opening and closing system. A separate line is dedicated to filling large cylinders on in-line filling scales.
The outcome
We delivered a filling plant with state-of-the-art equipment that yields an output of up to 800,000 cylinders per year with an outstanding filling accuracy: between 98.8% and 100% of the cylinders come out correctly filled.
Scope of supply
- 24 post filling carrousel
- Dual head filling heads on carrousel
- Automatic valve opening and closing system
- 4 in-line filling scales for large cylinders
- Check scales
- Leak detectors
- Chain conveyors
In 2007 Innogas approached Siraga (today known as MAKEEN Energy) to discuss a project to completely upgrade their filling plant at Porvoo, near Helsinki. A project that eventually turned into a replacement of the existing filling plant installed by another supplier in the beginning of the 1990s. The contract was signed in 2008 and the equipment installation began in January 2009. The plant has been running at its full capacity since February 2009.
A unique solution to meet a unique requirement
The Porvoo plant processes 16 different cylinder types on an everyday basis equipped with different valve types including clip-on, FLT and various hand wheel types, and cylinders made from composite, aluminium, steel or stainless steel.
To process such a diverse cylinder park Siraga decided on two separate filling lines. The main line boasts a 24 post filling carrousel fitted with dual head filling heads for top entry and side entry valves for small and medium sized domestic cylinders. The system features automatic valve opening and closing. The second filling line is dedicated to filling large cylinders on four in-line filling scales.
Both lines are fully equipped with safety functions such as weight-checking and leak detection of all cylinders.
The philosophy behind the project
The entire philosophy of this project can be summarised in five statements.
- Independence - Each machine and each filling line operate independently in order to avoid critical and costly production stops during the peak season.
- Flexibility - The cylinders may be filled on the carrousel and/or on the in-line scales. Both lines are easily adapted to a change of production in less than five minutes.
- Modularity - The plant layout of the required processes considers both the present needs as well as future expansion plans.
- User-friendliness - The operators at the plant and the local health & safety authorities validated and approved the safety and user-friendliness built into Siraga's solution. This includes machine cycle modifications, extra functions and on-going consultancy.
- Expertise - Innogas' own measurements prove that Siraga's technical solution yields an outstanding filling accuracy of 98.8% to 100% of all cylinders being correctly filled.
