JWI J-Mate Sludge Dryer | JWI 360G Parts & Replacement Dryer
The JWI J-Mate sludge dryer has been one of the most successful continuous sludge dryers utilized throughout the metal finishing and industrial wastewater industries. Originally developed by JWI and later sold through US Filter, Siemens, Evoqua and Xylem, thousands of pounds of metal hydroxide sludge are dried every day utilizing these systems.
Although ownership of the product line has changed several times over the years, many JWI J-Mate sludge dryers remain in service today.
Met-Chem provides engineering support, replacement components and complete replacement sludge drying systems for every generation of the J-Mate dryer.
We support:
- JWI J-Mate Dryers
- US Filter J-Mate Dryers
- Siemens J-Mate Dryers
- Evoqua J-Mate Dryers
- Xylem J-Mate Dryers
Whether you require replacement components or are considering replacing an older system entirely, our engineers can help.
Batch Sludge Dryer
Is It Time to Replace Your JWI J-Mate Sludge Dryer?
The JWI J-Mate 120G, 180G, and 360G continuous sludge dryers have earned a reputation for durability, and many units installed in the 1980s and 1990s are still operating today. For facilities with well-maintained equipment and consistent sludge production, repairing an existing dryer may continue to be the most economical option. Met-Chem continues to support these legacy systems with replacement parts, technical assistance, and engineering support.
However, every piece of equipment eventually reaches a point where increasing maintenance costs, aging electrical controls, obsolete components, and reduced reliability begin to outweigh the cost of continued repairs. If your facility is experiencing frequent downtime, difficulty locating replacement parts, or increasing energy and maintenance expenses, it may be time to evaluate a replacement sludge dryer rather than another major rebuild
Why Many Facilities Are Choosing Met-Chem Batch Sludge Dryers
Although the original JWI J-Mate was designed as a continuous sludge dryer, many industrial wastewater treatment facilities have found that a batch sludge dryer better matches the way their wastewater treatment systems actually operate. Since most industrial filter presses operate in batches, a batch sludge dryer allows operators to load an entire filter press discharge, dry it under controlled conditions, and discharge the material only after the desired moisture content has been reached.
Met-Chem batch sludge dryers use indirect heating with continuously mixing augers to provide even heat distribution and consistent drying while minimizing the risk of localized overheating. Available in natural gas, electric, steam, or hot water configurations, these dryers can often reduce sludge disposal costs by 50–75% while offering simple controls, externally mounted bearings for easier maintenance, and designs that can be customized to fit existing plant layouts. Typical payback periods range from one to two years, depending on sludge volume and disposal costs.
Whether you decide to repair your existing JWI J-Mate or upgrade to a new Met-Chem batch sludge dryer, our engineers can help evaluate your current equipment, operating costs, and production requirements to recommend the solution that provides the best long-term value.
Considering an Upgrade?
If your JWI J-Mate 120G, 180G, or 360G is becoming difficult to maintain, contact Met-Chem for a no-obligation evaluation. We'll help you determine whether rebuilding your existing dryer or replacing it with a modern batch sludge dryer provides the best return on investment.
