Mechatronics offers a variety of AC fans with a tachometer alarm option. Equipped with a Hall Effect sensor, these units allow for monitoring of the fan’s rotation via a one-pulse-per-revolution square wave output. This can be a great solution to monitor fan speed and/or operation to protect your system from overtemperature failure due to low airflow.
Features
- Ability to monitor fan RPM
- DC alarm output signal
Applications
- Industrial
- Telecommunications
- HVAC

Mechatronics DC Fans with thermal speed control enable the fan to automatically adjust RPM at set temperatures. For example, at 25° C or less, the fan will operate at roughly half speed. This promotes high energy efficiency and the lower RPM reduces the noise significantly. At 35° C or greater, the fan will operate at full speed. Between 25° and 35° C, the fan speed will automatically adjust based on the ambient temperature. Choose between a hub mount or remote mount thermistor to best suit your application needs.
Features
- Automatically adjusts RPM based on temperature
- Hub or remote mount sensor
- High energy efficiency and low noise when full speed is not needed
Applications
- Medical
- Servers
- Telecommunications

Mechatronics strives to advance their product designs to improve performance and usability. In doing so, Mechatronics offers the standard motorized impeller package as well as a unique configuration that combines the impeller and inlet ring in one complete package. The integrated inlet ring doubles as a mounting plate.
Standard motorized impeller integration requires an inlet ring to block the exhaust air from re-entering the air intake. For optimal performance, the inlet ring must be mounted to an adjacent surface aligning it with the impeller intake.
Mechatronics integrated inlet ring option eliminates the need for an additional adjacent surface for an inlet ring. Simply mount the device and power it up. This simplifies integration as well as reduces your assembly labor time.
Advantages of the Integrated Inlet Ring
- Easier to install
- Reduces labor time
- Optimizes air intake for optimal performance
Applications
- HVAC
- Refrigeration
- Rack cooling
- Heat exchangers
- Exhausting

Standard and Custom Fan Trays
Fan trays provide your equipment racks and enclosures with high-volume airflow to keep your equipment cool. These fan trays can be assembled using AC, EC, or DC fans with options for vertical or horizontal airflow. All fan trays are between 1 RU and 3 RU and are designed to fit any 19” rack application. Temperature-controlled fans are available as an optional add-on for EC and DC fan trays. Standard fan trays are available in dual voltage, low-noise, and high-speed models. Optional monitoring and alarm systems are available for applications with limited access. EC Fan Trays offer a universal voltage range for more design flexibility.
Modular Fan Trays
Built with modular fan assemblies on a 1RU high heavy-duty steel frame, Orion Fans’ modular fan trays are ideal for use in enclosures, cabinets, equipment racks, or ventilation hoods. These fan trays are prewired for three fans, six fans, or nine fans to accommodate specific cooling needs. A three-fan expansion module is available for the user to expand the tray as needed should design requirements change.
Short Fan Tray Series
Our short fan tray series is 1 RU (1.75in) high and features a shortened body. It is available in either a three-fan or six-fan configuration. This tray is perfect when extra space is needed behind the unit.
1 RU High Fan Panel with Redundant Power Supply
This fan tray option comes with six front exhaust fans perfect for cooling networks and rack enclosures. An optional redundant power supply will switch on seamlessly when the primary supply encounters a power loss.

Forced convection is a mechanism in which fluid motion is generated by an external source like a pump, fan, or other device. While the term forced convection can be used to refer to any fluid, it is most commonly associated with forced air cooling. Because of the usually high airspeeds associated with forced convection, significant amounts of heat can be transported quickly and efficiently. The amount of surface area on the heat sink is an important factor in helping meet the desired thermal performance, but too much surface area will cause the heat sink to have a large pressure drop. The greater the drop in pressure, the greater the strain put on the fan, which results in decreased fan performance. Wakefield Thermal engineers will help find the optimal operation point to achieve your thermal requirements.
Skived Fin heat sinks can be an alternative to extruded heat sinks when looking for a fin density that can’t be achieved by extrusion technology. Skived heat sinks can be manufactured from either copper or aluminum and usually have 0.5 (0.020”) thick fins. Skived heat sinks are produced using a series of sharp knives that, as they pass over the material, curl up a small thickness of metal which is then bent vertically to form the fin. Skived fins are produced from a bar of material that is approximately 16 feet in length and then cut to length as required by the final application. The final heat sink can be machined using normal fabrication techniques. Because of the thin fins, care must be taken in handling to prevent damage. It is suggested that a shroud be placed over the fins to help prevent damage.
Zipper Fin heat sinks can be an alternative to both extrusion and skived when looking for high-density structures. Unlike skived fin, a zipper fin heat sink is an assembly of a base and a fin stack that are soldered or bonded together. The fin stack is created using a set of individually stamped fins which are joined together in several locations along the top and bottom edges. The location and number of joining features are determined by the design. Since the fins are stamped individually, they may have any shape and include other stamped features. While zipper fins are most often used with a base plate, they can also be used with heat pipes. Hole(s) is/are stamped into the fins and the fin stack set is placed on a series of heat pipes to form the heat sink. This type of construction is generally found in CPU coolers. Zipper fins can be manufactured from either copper or aluminum and it is possible to mix the different materials within a fin stack. The base can be either aluminum or copper as well. Depending upon the materials used, the finish is either a nickel plate or a chromate, either of which will improve the thermal performance and provide environmental protection.
