NAK takes pride in the ability to serve our customer base quickly and efficiently without compromising quality. The company has several fully staffed construction crews that can respond to all of our customers’ needs. Available field services range from complete kiln rebuilds to annual outages to on-site inspections and assessments.
NAK offers on-demand scheduled services for various industries and facilities across the continental United States. Projects vary in size depending upon our customers’ needs. NAK has the capabilities to supply and install new complete kilns, with several of these projects having been completed over the last 5 years. A majority of NAK’s work is performing annual outage work for facilities across the US.
As a collective, the NAK team has the knowledge and means to deliver quality results to our customers. Our field superintendents possess decades of combined knowledge and have the expertise needed to deliver excellent results and keep rotary equipment running at its best.
Annual maintenance is key to long lasting, reliable equipment. Our team members work with plant employees to put together yearly maintenance plans that are proven to extend the life span of the kiln. Many key components of these machines have lead times of 10-20 weeks. If one of these components were to unexpectedly fail, the plant could experience a long shutdown with costly effects.
Bearing and gear inspections are performed often by our construction crews to prevent our customers from experiencing significant shutdowns due to unexpected failures.
Shell section replacement is a service frequently performed by our craftsmen. Our experienced field personnel are key to successful and efficient installations. Personnel are trained to follow industry and safety standards which plays a large role in our success. NAK’s foremen collectively contain decades of kiln experience and have a wealth of knowledge in rigging and lifts.
A damaged shell should not be run for an extended period of time. Continuing to operate a kiln with a damaged shell can result in excessive unscheduled downtime, increased refractory costs, and could lead to catastrophic failure of the shell and/or collateral damage to the surrounding equipment. NAK has the means to prevent and repair this issue.
NAK offers a variety of drive train repair services. Capabilities include:
1. New gear and pinion installation
2. Drive train inspection
3. Component replacement (includes drive base, reducers, couplings, motors, and clutches).
4. Coupling alignments
5. Gear reversals
NAK offers 24/7 emergency repairs and kiln preventative care services. A technical advisor can be on site in 24 hours or less in the case of an unexpected kiln failure. We understand the importance of getting equipment back up and keeping downtime to a minimum.
We can repair or replace rotary tires and the many related components. All service work meets or exceeds OEM standards. Our available services range from on-site inspections and assessments to field installation and calibration.
Wear profiles on the faces of tires and trunnions create conditions that cannot correct themselves. Uneven contact surfaces (concave, convex, or taper) can make it difficult to control the thrust of the kiln, which in turn leads to a slew of other problems.
NAK offers onsite machining and grinding services for tires, rollers, and thrust rollers. Tires can be machined up to a speed of 3.5 rpm tires and 5 rpm for rollers. Our technicians remove the deepest pitting and concave/convex profiles using patented mobile machining and grinding technology.
Unlike many of our competitors, we offer fixed pricing for our grinding services.
Following the replacement of a roller or gear, a kiln technician should be present for the heat up of the kiln. These technicians monitor the kiln for any high thrust, hot bearings, or unexpected issues. NAK can supply a technician(s) to oversee your next kiln startup at request.
Rotary Kilns are subject to many static and dynamic stresses that are sometimes due to underlying mechanical or thermodynamic problems. A kiln alignment will address these issues and optimize the longevity of constituting elements in the system while resetting the kiln to OEM parameters.
Hot kiln alignments are performed when the kiln is running. Cold alignments are performed when the kiln is shut down.
The effect of an unexpected shutdown or component failure could be devastating financially and mechanically. NAK’s offered alignment services save our customers from unexpected downtime & more. These surveys are also a helpful tool when planning for future shutdowns. A formal report will be sent to the customer following the procedure that records all results and recommendations and provides a timeline of when critical repairs need to be performed.
Elevate your kiln operations with our comprehensive consulting services. We understand the critical role kilns play in industrial processes and offer specialized expertise to optimize their functionality.
Utilizing advanced technology, we conduct comprehensive 3D shell profile analyses, providing a detailed assessment of kiln structures. This process allows us to identify potential weaknesses, heat distribution issues, and optimize the kiln’s overall performance, extending its lifespan and minimizing downtime.
Our team specializes in crafting cutting-edge systems tailored to optimize industrial kilns for peak performance. We analyze existing setups, strategize improvements, and implement custom designs that enhance efficiency and productivity while ensuring safety standards.
Equip your team with the latest industry knowledge through our engaging and informative training seminars. Led by experts in kiln repair and maintenance, these sessions cover a range of topics, from best practices in upkeep to troubleshooting common issues, empowering your staff to handle kiln-related challenges effectively.
The mission of NAK is to prevent our customers from experiencing costly unscheduled, yet predictable, mechanical failures. This is accomplished by expert understanding of kiln mechanical components and complimented by a dedicated effort to form relationships with those we serve.
