Merdec One Only Chain Scrapers
Chain & Flight type Sludge and Scum Collectors
Merdec
With over 30 years’ experience in chain and flight collector systems design and manufacturing has given us a solid base to bring a new updated system to the market. During the designing of this system, Merdec has carefully taken into account all the most important factors for the benefit of the customer.
The "One Only" Merdec chain scrapers are suitable for various types of rectangular settling tanks and our components can also be used in many existing systems in the market. Our chain scrapers can be provided as top, bottom, 4-shaft, 3-shaft or multi-layer scraper systems for many types of applications such as wastewater treatment, DAF, desalination or water treatment.:
- Most Merdec Chain scraper components are suitable in almost all existing systems.
- Suitability in wide range of applications and operation conditions
- One piece chain link and other carefully designed features ensure the system is easy to install and maintain
- Long service life and low operating costs (minimal water absorption, changing most of components without emptying the tank, design solutions to allow for minimal wear and tear)
- Cost-effective price structure (Quick ROI)
- High quality construction materials and components
Scraper component sales
Additionally, to complete systems, Merdec provides components for almost all existing chain scraper systems in the market whether it’s spare parts or for refurbishing. Our components are compatible with most of non-metallic Chain and Flight Collectors. We also provide and design complete systems to customers by supplying the complex parts while designing some parts for the customer to be produced locally (e.g. stainless steel shafts and rails). When heavy and bulky parts such as stainless-steel components are produced locally avoiding transfer through sea, it saves both the customers’ money and the environment!
