About SupEd Server Pro


a compact fanless PC for harsh environments with Xeon and Quadro


a high-performance ruggedized fanless PC for edge computing and  industrial applications that require deployment in harsh conditions.  Based on Intel® Xeon® Processor E3-1275 v6 with an optional NVIDIA  Quadro P4000 – both passively cooled using Compulab proprietary Natural  Airflow technology and with a volume of just 7.5 liter – SupEdAir Pro  redefines the performance level of compact fanless PCs.

Other remarkable features of Airtop2 are up to 64 GB DDR4,  high-performance storage sub-system with 2x NVMe + 4x 2.5” SATA SSDs /  HDDs, tool-free service and a broad selection of FACE Module extensions.

SupEdAir Pro is available at an industrial temperature range of -40°C to 70°C and ships with 5 year warranty.

Note: SupEdAir Pro is intended for professional  applications. A variant of Airtop2 intended for silent-PC enthusiasts  named “SupEdAir Pro Inferno” powered by GeForce GTX 1080 graphics card will  be introduce separately during Feb-2018.


Natural Airflow technology

Passive cooling is silent, reliable and requires no maintenance.  Airtop2 achieves fourfold improvement in passive-cooling efficiency by  Compulab’s Natural Airflow cooling technology – a novel heat-exchange  system that stimulates airflow without moving parts, and by cooling each  of the 3 major heat sources (CPU, GPU and storage devices) using a  dedicated thermal zone independent of the other two.

Natural Airflow (NAF) technology is based on a multi-stage  heat-exchanger. The first stage is a mirror-polished copper-plate  attached to the hot spot. The 2nd stage is a set of high-performance  flat heat-pipes arranged in a crisscross array that spread the heat  evenly onto the surface of the air-tubes panel. The last stage is upward  airflow generated inside the air-tubes by the stack effect due to the  temperature gradient between the air-tubes and the air within.

Natural Airflow cooling is effective at an extremely broad  temperature range. This allows Airtop2 to operate under load at ambient  temperatures exceeding 70°C. NAF cooling is not subject to clogging, is  not sensitive to dust and moisture and requires no maintenance thanks to  not having any moving parts, filters or tight airways found in  computers with traditional forced-air cooling.


Industrial design

Despite being small and fanless Airtop2 excels in ease-of-use. RAM  and storage-devices are easy to reach with a tool-free clamshell opening  mechanism. The front panel incorporates the I3M (Integrated Interactive  Information Monitor) which shows on an embedded OLED display data like  temperatures and power which the I3M acquires from the motherboard and  operating system in real time.

“With a 2nd generation product like Airtop2 we usually observe high  customer satisfaction” said Irad Stavi, Chief Product Officer at  Compulab. “NAF cooling worked extremely well in Airtop1 and is now  considered field-proven technology. In Airtop2 the core components –  CPU, graphics and RAM are modernized with increased capacity and  performance, the storage system is completely revamped and is now not  only on-par with storage of current small-form-factor PCs but has  best-in-class performance, capacity, cooling and serviceability.  Professionals and enthusiasts alike have a keen interest in Airtop2 but  while professionals focus on ruggedization and modularity, enthusiasts  care for performance and silent operation. Airtop2 is geared towards  professionals. For enthusiasts we are introducing an  enhanced-performance variant – the Airtop2 Inferno.”

Airtop2 7.5 liter housing is all-aluminium. The die-cast and machined  parts fit seamlessly to make a ruggedized enclosure with functional  elegance.

Motherboard and core-components

 SupEdAir Pro  core-components are selected to provide balanced high  performance for the most demanding edge-computing workloads.  Core-components comprise of a Xeon-E3 CPU coupled with a Quadro GPU  (both cooled passively) supplemented by up to 64 GB DDR4.

The motherboard is designed from the ground up to combine effective  NAF cooling, optimal serviceability and enhanced reliability. The  motherboard includes many novelties like redundant power supplies,  sockets facing the clamshell door for simple tool-free upgrades and  rigid-flex PCIe adapter to install full-height cards parallel to the  motherboard.

“A design goal of Airtop2 is to be able to operate unattended  indefinitely.” said Yuval Sela, Airtop hardware architect. “For that we  completely redesigned one of the most sensitive circuits on a  motherboard– power sequencing. Instead of an analog power-sequencing  circuit Airtop2 has a dedicated programmable logic device that monitors  power control signals. It allows an always-accurate response to changes  in power-states and fluctuations in external power. This brings a new  level of reliability and stability to Airtop2.”


Graphics and display

SupEdAir Pro  is the only small-form-factor PC in the market that includes a  passively-cooled 120W graphics card. Airtop2 can drive the displays of  discrete and integrated graphics simultaneously for a total of 7 4K  displays.

Having a ruggedized, small, silent and maintenance-free system with  workstation-class graphics is beneficial in control rooms, outdoor  digital signage and many other use-cases. With the increasing use of  GPUs for computation Airtop2 opens new possibilities for running  computation-intensive applications in harsh environments.

The graphics card in  SupEdAir Pro  can be upgraded. Compulab supplies a ready-to-use NAF-cooled graphics card that is easy to install.
