Kadant

Kadant is a global supplier of industrial process equipment, specializing in steam technology, rotary joints, fluid filtration systems, and thermal management for the paper, cardboard, and industrial manufacturing industry. The company, headquartered in Westford, Massachusetts, USA, delivers advanced engineering solutions for process optimization and energy efficiency. At Verkopershulp.nl, more than 817 Kadant products are available.

Kadant's core range includes rotary steam joints and siphons for steam-heated cylinders in paper and cardboard mills. These rotary joints provide continuous steam supply to rotating cylinders while efficiently draining condensate. The Kadant Johnson and Kadant DRYING division are market leaders in drying cylinder technology and supply products for improving energy efficiency in paper and board drying processes.

Kadant also delivers complete fluid filtration systems for the paper industry, including pressure screens, clean water filtration systems, and retention aid dosing systems. This equipment is essential for producing high-quality paper and cardboard with minimal wastewater. The Kadant Lamort series rotary drums and pressure screens are renowned in paper fiber preparation.

In addition, Kadant offers industrial heating and cooling systems, steam condensate management systems, and oil extraction equipment for wood and biomass processing industries. The acquisition of multiple specialized companies has expanded Kadant's portfolio to dust separation, hydraulic systems, and industrial cutting machines.

At Verkopershulp.nl, you can order the complete Kadant parts range. Our specialists advise you on the correct rotary joint technology, steam cylinder accessories, and filtration systems for your process installation.

Kadant also delivers complete consultancy and engineering services for optimizing drying processes in paper and cardboard mills. Kadant technical teams analyze steam systems, measure energy losses, and advise on improvements resulting in significant energy savings and higher productivity. This service-oriented model distinguishes Kadant from purely component-oriented suppliers and makes it a strategic partner for producers in the paper and packaging industry.

Beyond core technology for the paper industry, Kadant has expanded its activities to markets such as bio-energy and industrial biomass processing through its Kadant PAAL division for compacting and baling systems. The wood and biomass processing division supplies complete processing lines for the production of wood pellets, energy biomass, and recycled wood. This diversification strengthens Kadant's position as a fully developed technology company for creating value from biomass and paper fiber.

History

Kadant was founded as Johnson Industries in 1899 and grew into a technology company specializing in steam technology for the paper processing industry. After multiple name changes and strategic acquisitions, including the takeover of Lamort in 1997 and Black Clawson in 2012, the name was consolidated to Kadant Inc. The company moved its headquarters to Massachusetts and expanded its technology portfolio with advanced filtration systems and biomass processing equipment. Today, Kadant is a publicly listed technology company with more than 3,000 employees and offices in more than 20 countries. Kadant's technological expertise was reinforced by the acquisition of Thermo Fibertek in 1999, adding advanced fluid management and fiber preparation technology to the portfolio. The strategy of targeted acquisitions has transformed Kadant from a steam technology specialist into a full platform for paper industry technology and biomass processing.

Frequently Asked Questions

What is a rotary steam joint and what is it used for?
A rotary steam joint is a mechanical seal that transfers steam or hot fluid from a fixed pipe to a rotating cylinder or drum without leakage. They are extensively used in the paper industry for heating drying cylinders via steam and draining condensate while the cylinder rotates.
Which Kadant rotary joints are suitable for high-pressure steam applications?
Kadant Johnson delivers rotary joints for steam pressures up to 20 bar and temperatures up to 215 degrees Celsius. The FH series and MR series are specifically designed for high-pressure applications in paper drying cylinders with large cylinder peripheral speeds up to 35 m/s.
Are spare parts available for Kadant rotary joints?
Yes, we supply seals, bearings, couplings, and other wear parts for Kadant Johnson rotary joints. Timely replacement of seals and bearings significantly extends the service life of the rotary joint and prevents costly production loss due to steam leaks.
How quickly are Kadant products delivered through Verkopershulp.nl?
Common spare parts in stock are shipped the same business day. Delivery in the Netherlands is typically within 1-2 business days. Non-standard parts or complete rotary joints are typically delivered within 2-6 weeks from the Kadant production center.
Which Kadant pressure screens are available for paper fiber preparation?
We carry Kadant Lamort rotary drums and pressure screens for paper fiber suspensions, including pressure sorting machines for primary and secondary screening of paper fiber. These are available in various capacities for both virgin fiber and recycled fiber processing.
Does Kadant also offer complete steam-condensate system solutions?
Yes, Kadant delivers complete steam condensate management systems for paper drying installations, including steam rotary joints, siphons, steam traps, condensate return lines, and associated measurement instrumentation for energy optimization of the steam system.
Are Kadant products compatible with existing non-Kadant drying cylinder installations?
Yes, many Kadant rotary joints and accessories are designed as drop-in replacements for existing installations from other manufacturers. Our technical department helps you identify the correct replacement based on your existing flange dimensions, connections, and operating parameters.
What energy savings are achievable with Kadant steam optimization technology?
Kadant steam optimization systems can reduce steam consumption in paper drying installations by 5 to 20 percent through improved condensate management, more uniform steam distribution across drying cylinders, and minimization of steam leaks. This leads to significant cost savings at high steam rates.
