Engineered Products for Harsh Environments

Built to Perform Where Others Don't

Every product line was developed from real application experience. In substations, on Navy vessels, underground in mines, and in industrial facilities where the environment makes engineering shortcuts expensive. These are not catalog items adapted to fit. Low-volume. Custom configurations. Made in Iron Mountain, Michigan.

Most products can be configured to application-specific requirements, and in every case, engineering support is part of what you’re buying, not an add-on. If you’re not sure which product fits your application, then let’s start a conversation.

Relay Control Panels Built to Your Specifications, Delivered On-time

Substation control panels built to your relay selection and configuration requirements, with full wiring, testing, and documentation, at low and medium volume.

Electric utilities, co-ops, and municipalities need relay control panels for substations: recloser controls, circuit switcher racks, and protection relay panels that monitor and direct power distribution equipment.

When you partner with ACS, you get relay control panels built to your supplied specifications with the same engineering rigor a large contractor brings to a 500-panel run. Full wiring, functional testing, and complete documentation on every order, regardless of quantity.

Applications:

Recloser control panels for distribution substations
Circuit switcher racks and protection relay assemblies
Battery enclosure and auxiliary control systems for electric utilities
Custom substation panels for co-ops, municipalities, and independent power providers

You Get:

Low-quantity orders taken seriously, with the same engineering attention and documentation quality as a large panel program
Per-panel customization accommodated without the friction of working against a standard product line
A supplier built for the procurement realities of small utilities and co-ops, not just large transmission operators

Custom Industrial Control Panels Engineered for the Equipment, the Environment, and the Installation Reality

Engineered control panels for industrial applications, designed for the environment, the equipment, and the requirements you haven’t fully defined yet.

Panel shops build to drawings. When you have a specific outcome in mind but not a complete specification, that distinction matters. For industrial customers who need a control panel that integrates with specific equipment, fits a specific footprint and environment, and requires advanced functionality, working with a supplier that has real engineering capability changes what’s possible.

With ACS, you get a partner that designs and builds custom control panels for pumps, blowers, compressors, fans, and heavy industrial machinery, and helps you get from a defined outcome to a complete specification. The panel is the product. The engineering that defines it is what separates ACS from an average panel builder.

Applications:

Motor control panels for industrial pumps and blowers
Machine control systems for custom or legacy industrial equipment
Harsh-environment panels rated for dust, heat, vibration, and continuous-duty cycles
PLC-based controls replacing obsolete relay logic in active industrial equipment

Key Benefits:

An engineering partner who helps you define the requirement, not just execute against one
Panels built for your environment, your equipment, and your installation reality, not adapted from a standard design
Real engineering judgment on every project, so you don't get a panel that works on the bench and fails in the field

Naval HVAC Controllers

Naval HVAC Controllers Designed for Shipboard Qualification from Day One, Not Adapted After the Fact

Proportional heater controllers, fan controls, and air handling unit controls built for shipboard qualification and U.S. Navy program requirements.

Shipboard HVAC systems operate in conditions that disqualify most commercial control products: vibration, corrosion, shock loads, and documentation requirements that don’t stop at delivery. When you need an HVAC controller that can pass naval qualification and come with a complete documentation package, adapting a commercial product to fit is not the answer.

ACS has designed and supported HVAC control systems for U.S. Navy programs for over 20 years, including proportional heater controllers, fan coil unit controls, and air handling unit controls sourced by shipyards and HVAC system integrators. These controllers are designed from the qualification requirements forward. You get full CDRLs, test documentation, and engineering support that naval programs require, with no documentation scramble at the end of the program.

Applications:

You Get:

Controllers designed for shipboard qualification from the start, with documentation packages built in, not assembled under pressure at the end
Over 20 years of U.S. Navy HVAC program experience behind every product, not a new supplier learning the requirements on your program's timeline
Full engineering support through design reviews, qualification testing, and any program changes that come after initial delivery

UNREP Systems

UNREP Systems Engineered by a Team With 20+ Years of Dedicated Underway Replenishment Program Experience

Underway Replenishment control and mechanical systems from an engineering team that has been building UNREP equipment for the U.S. Navy for over two decades.

Underway Replenishment systems operate in one of the most demanding environments in naval engineering: open ocean, continuous operational use, and zero tolerance for equipment failure during a connected replenishment. When you’re sourcing a UNREP subsystem or lifecycle support for a system already in service, you need a supplier whose experience with the application is real, not claimed.

ACS has been designing UNREP equipment for the U.S. Navy for over 20 years. That’s not a reference. It’s the engineering foundation every UNREP project is built from. When you partner with ACS on a UNREP program, you get an engineering team that has navigated the qualification requirements, documentation demands, and fleet-entry challenges of this application before, and can do it again on your program’s timeline, not in spite of it.

ACS supports UNREP programs from concept and requirements definition through manufacturing, qualification, and lifecycle sustainment, including repair, retrofit, and engineering support for systems already in service.

Applications:

Controls for UNREP systems and equipment
Mechanical drive and tensioning systems for connected replenishment equipment
Retrofit and lifecycle support for UNREP systems in active service
New program engineering support for UNREP-adjacent shipboard equipment

Partnering with ACS gives you:

Custom Shipboard Controls Built to Pass Qualification, Perform for the Life of the Vessel, and Arrive with the Documentation Your Program Requires

Custom shipboard control systems and panels built for Navy compliance, harsh-environment performance, and the documentation discipline naval programs demand.

Shipboard control systems must pass qualification before they see the water, and they must perform for the life of the vessel after they do. When your program requires a custom control system or panel, you need a supplier who treats compliance documentation as part of the deliverable, not a follow-on task.

With ACS, CDRLs, submittals, and reps and certs are built in from day one. You get a supplier that works with shipyards and prime contractors at all phases, from requirements definition and system design through manufacturing, installation support, and qualification. When design changes come, and they will, you get a partner who stays engaged through revisions, testing, and sea trials, not one who ships and steps aside.

Applications:

Custom shipboard control panels for Naval vessels and support craft
Electrical control systems for ship machinery, auxiliary systems, and mechanical equipment
Qualification-ready control packages for new construction and modernization programs
Engineering and documentation support for shipboard systems at any program phase

You Get:

Compliance documentation built in from day one so your procurement team isn't chasing submittals at the end of the program
An engineering partner that stays engaged through design changes, testing, and sea trials
Low-volume custom shipboard controls taken seriously and prioritized because of their unique demand in your system

Jackshaft Systems That Reduce Maintenance Downtime and Extend Bearing Life on High-Horsepower Applications

Engineered jackshaft systems with integrated belt tensioning for 500+ HP applications, built to extend bearing life, reduce maintenance time, and lower total operating cost.

Standard slide-base jackshafts get the job done until belt tension is off, maintenance windows stretch from two hours to eight, and bearing failures start shortening equipment life. When you’re running rock crushers, pumps, or blowers continuously in a mining or industrial environment, that math gets expensive fast.

With an ACS jackshaft system, you get an engineered drive solution built for high-horsepower belt-driven applications, typically 500 HP and up, with integrated belt tensioning that gives your maintenance team a repeatable, gauge-controlled process. Belt changes that take a full shift on a slide-base system take two hours on an ACS tensioned jackshaft. Belts last longer. Bearings last longer. Drive efficiency improves.

ACS sells primarily to OEM crusher and equipment manufacturers who build the tensioning advantage into their product offering, and to mining operations and industrial facilities buying direct for aftermarket replacement or upgrade.

Applications:

Rock crusher jackshaft systems for surface and underground mining operations
High-horsepower pump and blower drive systems with integrated tensioning
Replacement jackshaft systems for aftermarket and OEM upgrade applications
Industrial belt-driven equipment above 500 HP requiring engineered drive solutions

You Get:

A documented reduction in belt change time that justifies the investment to operations and maintenance leadership
Extended belt and bearing life through accurate, repeatable tensioning on every maintenance cycle
An engineered solution sized and configured for your specific equipment, not a catalog part adapted to fit

Belt Tensioning Systems That Cut Maintenance Time, Extend Belt Life, and Reduce the Cost of Running High-Horsepower Drive Equipment

Standalone automatic belt tensioning systems for high-horsepower industrial and mining applications. Reduce maintenance time, extend belt and bearing life, and improve drive efficiency without replacing your existing machinery.

Improper belt tension is one of those maintenance problems that gets accepted as a cost of doing business until someone actually quantifies what it’s costing. Reduced drive efficiency. Accelerated bearing wear. Shortened belt life. And a belt change that turns into a half-day operation because there’s no repeatable process for getting tension right.

With an ACS belt tensioning system, you get a standalone retrofit that installs on your existing foundation and equipment’s frame. Your maintenance team gets a gauge-controlled tensioner that takes the guesswork out of every belt change, reduces the physical effort and time required, and gives you a consistent process that delivers consistent results. The tensioner pays for itself. ACS can show you the math.

Applications:

Standalone tensioner retrofit for existing machinery and foundations
Belt tensioning for conveyor drives, pumps, and blowers in mining environments
Industrial equipment belt drive upgrades for improved maintenance intervals
High-horsepower applications where belt and bearing life are limiting operational uptime

You Get:

Longer belt life and longer bearing life through accurate, repeatable tensioning on every maintenance cycle
Faster belt changes with less physical effort and a repeatable process your team can execute consistently
Increased operating efficiency on high-horsepower drive equipment
A retrofit solution that improves performance on your existing equipment without replacing the machinery

Not Sure Which Product Fits Your Application?

Most ACS products are configured to application requirements: operating environment, load, duty cycle, and compliance context. If you’re not sure where to start, describe the application. That’s what the first conversation is for.

The Product Is the Starting Point. The Engineering Is the Differentiator.

Every product ACS manufactures comes with the engineering judgment, application knowledge, and documentation discipline that a panel shop or catalog supplier can’t provide. When the environment is harsh, the application is specific, and getting it wrong is expensive, that’s where ACS builds value.
