CRI Device Cooling Solutions

Designed and Built Under One Roof

Common Cooling Applications for CRI Controls

Built for OEMs who require precise, closed-loop temperature control for mission-critical hardware—from high-density data centers to medical diagnostic devices. By embedding proprietary functionality into your thermal management system rather than relying on restrictive standard controls, you can outperform the competition on reliability and efficiency. Every product is designed and manufactured in the USA under one roof by the same engineering team that supports you from prototype through final production.

CRI Cooling Designs Built Around Your Needs

Our product tiers are structured to match your exact thermal engineering and budget requirements:

Catalog Controls

Catalog Controls are standard, off-the-shelf controllers ready to ship immediately for baseline cooling applications like enclosures, medical equipment, and electronic devices.

Modified Standards or “Specials”

Modified Standard or “Specials” alter those core control boards with specific hardware or firmware modifications. These include adjusting dynamic fan-speed curves based on precise temperature sensors, adding critical thermal safety delays, optimizing for specific fan or motor types, and removing unnecessary features.

Fully Custom Design

Full Custom Designs are built completely from the ground up—whether evolved from an existing thermal platform or developed from a brand-new concept—to handle unique equipment enclosures, complex multi-fan consolidation, or specialized communication requirements across high-demand thermal environments including data center liquid/air cooling, telecom enclosures, medical device cooling and high-density electronics cooling.

Why OEMs Customize Device Cooling Systems

Off-the-shelf components shouldn’t dictate your product’s potential. Our custom engineering capabilities give you total control over form, fit, and function—allowing you to build precisely what you need, exactly how you envisioned it. Whether you are managing dense thermal loads in data center cooling, maintaining strict regulatory temperatures in medical device cooling, or ruggedizing systems for telecom cooling and electronics cooling, we engineer the exact brain your system requires.

Here are some reasons OEMs choose the custom route:

Tailored Signal Control & Integration

Stop forcing your equipment to speak a generic language. We design around your specific system architecture to maximize compatibility and performance—whether you are controlling fans, blowers, compressors, valves or other air handling or thermal control equipment.

Flexible Control Curves: Easily adjust and fine-tune dynamic control curves to match your device’s exact thermal profile. Program specific variables—such as CFM airflow, static pressure, or localized temperature thresholds over time—completely bypassing the limitations of rigid, pre-programmed curves. For example, if your enclosure or medical device requires a strict minimum volume of airflow for component safety, you can lock in an idle speed to meet that requirement down to the exact percentage point. You can also adjust the control slope to customize overall system response time. (See the graphs below for single-speed and two-speed device application examples).

Unique Signal Inputs: Move beyond restrictive, generic 0-10V inputs. We support specialized voltage ranges (e.g., 0-3V) to fit your precise architecture.

Direct PLC Reading: Streamline your setup with the ability to read a PWM signal directly off a PLC, eliminating the need for awkward converter modules in complex data center cooling infrastructures.

Single Speed Applications

Two Speed Applications

Data Efficiency

Get more functionality out of your existing bandwidth without upgrading your entire infrastructure:

Proprietary Data Formats

We replace standard, bulky character streams with compressed, proprietary data formats optimized for industrial and commercial environments.

Advanced Error Correction

By packing data more efficiently and adding robust error correction, we free up valuable processing space. This allows us to inject bonus functionalities—like predictive failure alerts or advanced telemetry—into your system using that reclaimed bandwidth.

Reliable Communication Protocols

We prioritize high-reliability control systems. By utilizing Modbus and optimized proprietary protocols instead of direct IoT or Bluetooth integration, we minimize firmware complexity and eliminate the common points of failure associated with wireless stacks. When wireless or cloud connectivity is required, we utilize external gateways to isolate the primary control logic.

Infinite Adaptability (Any Shape, Any Space)

Don’t redesign your enclosure to fit a standard board. We build the brain to fit the body.

System integration and board consolidation

Application-Specific Form Factors

We engineer custom PCBs that adapt perfectly to your specific dimensions, tight spatial constraints, and unique connector requirements. From ultra-compact medical device cooling systems to tightly packed server racks, if you have the space, we can fit into it.

System Integration & Board Consolidation

Reduce your bill of materials (BOM), minimize failure points, and save physical space by merging separate components into a single, intelligent unit.

All-in-One Architecture

Why use four boards when you only need one? We can seamlessly combine thermostat control, time delays, alarm relays, and multiple complex inputs into a single cohesive controller. This drastically simplifies supply chains and boosts reliability for mission-critical medical and telecom applications.

Device Cooling

What are the Advantages of Custom Cooling Controls?

Acoustic Management

Intelligent speed scaling ensures your fans only run as fast as necessary, minimizing noise and vibration.

Thermal Longevity

Predictive cooling stabilizes internal temperatures to prevent heat soak and significantly extend the operating life of your critical electronic components.

Fault Detection

Integrated tachometer monitoring provides real-time failure alerts, allowing your system to trigger safe-mode protocols before reaching catastrophic thermal shutdown.

Energy Efficiency

Our device cooling controls modulate fan speed based on thermal demand, which means your system draws only what it actually needs.
