Call us at (262) 288-2524 or visit our Locations page for full details.

Is Centrisys/CNP equipment made in the USA?

Yes. Centrisys/CNP is a US manufacturer, and our sourcing and manufacturing process meets Build America, Buy America (BABA) requirements — important for facilities using federal funding. We are also ISO 9001:2015 certified, supporting consistent quality management throughout our operations.

What industries does Centrisys/CNP serve?

We serve municipal water and wastewater treatment, animal protein and by-products, dairy and manure separation, food and beverage, mining and materials, oil and gas, pulp and paper, site remediation, steel and primary metals, and tunneling.

How does Centrisys/CNP customize a solution for my plant?

We start by listening to your goals and challenges, then run lab analysis of the abrasiveness, corrosiveness, and nature of your solids. We evaluate your plant and sludge conditions, conduct on-site pilot testing, and adapt the centrifuge design or treatment process to your findings. Design concepts are prototyped and tested in SOLIDWORKS before final delivery — so the equipment fits your actual operating conditions, not a generic spec.

Equipment Service & Repair

Does Centrisys/CNP service centrifuges from other manufacturers?

Yes. Our service team provides nationwide and global decanter centrifuge repair and on-site field service for all centrifuge brands. This includes retrofit and upgrade work for existing equipment, regardless of the original manufacturer.

How often should a decanter centrifuge be serviced?

Most facilities benefit from an annual inspection, with maintenance intervals adjusted to run hours, feed characteristics, and abrasiveness. Our Centrisys Service Inspection (CSI) Program provides a structured annual checkpoint to catch wear before it causes unplanned downtime. High-abrasion or high-throughput applications may need more frequent attention — our team can recommend an interval based on your operating conditions.

What is the CSI Program?

The Centrisys Service Inspection (CSI) Program is an annual, one-day, on-site inspection of a single decanter centrifuge or sludge thickener. Drawing on 30+ years of centrifuge service, our team checks 40+ critical areas that affect performance, reliability, and safety. The inspection produces a detailed report with photos, notes, color-coded condition ratings, and clear recommendations.

Do you offer emergency or urgent centrifuge repair?

Yes. When a centrifuge goes down during peak flow, every hour matters. Our field-service team is available 24 hours a day, 7 days a week for emergency repairs on all centrifuge makes and models. Contact us directly at (262) 288-2524 for urgent service needs.

Can Centrisys/CNP retrofit or upgrade my existing centrifuge?

Yes. We offer retrofit and upgrade services to improve the performance, reliability, and efficiency of existing centrifuges, including non-Centrisys equipment. Common upgrades include control panel modernization, wear-part replacement, and efficiency improvements.

Where can I find repair parts for my centrifuge?

Centrisys/CNP stocks a wide range of repair parts for our own equipment and for many other centrifuge brands. Visit the Service & Repair section of our website or contact our team to source the parts you need.

Industries & Applications

What is a decanter centrifuge used for?

A decanter centrifuge separates solids from liquids using high-speed rotation. In wastewater treatment, it is used to dewater or thicken sludge and biosolids, reducing volume for lower hauling and disposal costs. The same separation principle supports industrial applications such as manure separation, mineral processing, and produced-water treatment.

Can Centrisys/CNP equipment handle industrial applications, or is it only for wastewater?

Our equipment serves both municipal wastewater treatment and a wide range of industrial applications, including food and beverage processing, mining and materials, oil and gas, pulp and paper, animal protein and by-products, dairy and manure separation, site remediation, steel and primary metals, and tunneling.

What solutions does Centrisys/CNP offer for animal waste and manure management?

Centrisys/CNP provides dairy manure separation systems and decanter centrifuges built for animal-waste applications. These systems separate solids from liquid manure efficiently, supporting nutrient management, odor reduction, and resource recovery on agricultural operations.

Do you have solutions for the oil and gas industry?

Yes. Centrisys manufactures decanter centrifuges used in drilling-fluid management and produced-water treatment. We also manufacture a vertical cuttings dryer designed for oil-based drill cuttings management, for operators concerned about drilling-fluid losses and the environmental impact of oily cuttings.

Dewatering Centrifuge Rentals & Pilot Testing

Does Centrisys/CNP offer centrifuge rentals?

Yes. We maintain an active fleet of decanter centrifuge rentals for short- or long-term needs. Rentals are ideal for covering planned or emergency downtime, supplementing capacity during peak periods, or running operational trials before committing to a permanent purchase.

How much does a centrifuge rental cost?

Rental cost depends on the centrifuge size, rental duration, and the configuration your application requires, so we provide a quote based on your specific needs. Many facilities use rentals to avoid the larger capital cost of a purchase during planned maintenance or unexpected downtime. Contact our team at (262) 288-2524 to discuss availability and pricing for your situation.

Can I pilot test Centrisys/CNP equipment at my facility before buying?

Yes. We offer sample analysis and pilot testing at municipal or industrial plants, so you can evaluate performance under your actual operating conditions before making the investment. Pilot testing is a core part of how we size and configure the right solution for your specific needs.

How do I request a pilot test or sample analysis?

Visit the Sample Analysis & Pilot Testing section in our Resources area, or contact us directly through our website. Our engineering team will work with you to design the appropriate test protocol based on your sludge characteristics and treatment goals.

Are rental centrifuges available immediately in an emergency?

When unplanned downtime hits, getting equipment on-site fast is the priority. We maintain an active rental fleet and work to deploy equipment as quickly as possible for emergency situations. Contact us at (262) 288-2524 to discuss availability and logistics for urgent rental needs.
