HotSpotr Fan Assisted Data Center Airmovers
- Frequently Asked Questions
 

• What is the HotSpotr Data Center Airmover HT-510?
  • a. The HotSpotr HT-510 is an under floor active air mover mounted beneath a perforated tile for a raised floor data center. Its purpose is to boost the amount of cooling air delivered to IT racks. Temperature sensors mounted at the top-intake-side of the racks monitor and control air delivery.
• What is the difference between the HT-510 and the HT-510-T?
  • a. The HT-510 comes with a mounting kit that attaches to the stanchions under the raised floor, and should be used with a customer’s existing perforated tiles. We recommend perforated tiles of at least 50% open area to gain the full benefit of the HT-510.
  • b. The HT-510-T comes attached to the underside of a 56% open Tate® GrateAire® Tile, and does not require a separate mounting kit.
• How much power does the HT-510/HT-510-T consume?
  • a. When the fans are at full speed, the HT-510 consumes 2 Amps @120V. However, the fans are typically running at between 30% and 50% speed and consume less than 1 Amp @120V. Put into the context of the server racks they cool, the HT-510 consumes approximately 2.5% of the power being consumed by the rack.
• How long is the power cord? What type of plug does it have?
  • a. All North America market HotSpotrs come with a 6 foot power cord with a Ground Fault Circuit Interruption module at the end of the cord. There is a standard U.S. 120V 5-15 3-Pin grounded plug on the module.
• How many kilowatts per rack can the HT-510-T cool?
  • a. The HT-510 can safely cool between 10 and 12 kilowatts per rack (assuming that the customer has enough cooling tonnage available in the data center to support the IT load).
• How shallow can the raised floor be? What is the minimum floor depth that is required?
  • a. The HT-510-T can be installed in a 6 inch (or deeper) raised floor as measured from the slab to the top of the raised floor.
• Does the HotSpotr “steal” air from the adjacent perforated tiles?
  • a. No. We have conducted tests at various customer sites and we have never encountered a situation where we have starved adjacent racks of airflow. This is due to the thermostatically controlled VFD fans in the HT- 510. It will only draw enough air to maintain 77°F at the rack top intake and not waste cooling. Of course there needs to be enough total CRAC tonnage available to support the total IT load in the room.
• How much air can the HT-510/HT-510-T deliver?
  • a. At full speed, through a 56% Tate® GrateAire® tile, the HT-510 can supply 1200 CFM.
• What type of floors will the HT-510 and HT-510-T fit into?
  • a. The HT-510 can fit into any raised floor that uses 24” (or 600 mm. ask for etails) tiles.
  • b. Because it is supplied with a Tate® tile, the HT-510-T will fit into all Tate® compatible flooring systems. However, we also provide an adaptor kit that should allow the HT-510-T to also fit most non-Tate® flooring systems. The adaptor kit consists of spacer blocks attached to the supplied tile that insures proper fit with the surrounding tiles.
• Can the sensors in the HT-510/HT-510-T be networked?
  • a. Yes. We also offer a more comprehensive solution for total Data Center cooling and energy savings – “Demand Based Cooling or DBC for short. During the installation of the DBC solution, any HT-510 or HT-510-T HotSpotrs that the customer has already purchased can be incorporated into the DBC solution.
• What is the shipping size and weight of an HT-510 or HT-510-T
  • a. The HT-510 box size is 24.5 inches x 25 inches x 7 inches, and its weight is 25 pounds.
  • b. The HT-510-T box size is 24.5 inches x 25 inches x 7 inches and its weight is 38 pounds
• You claim to solve hotspots in 3 minutes. How is this possible?
  • a. When installed and powered on, the HT-510 will sense and deliver enough cool air to bring rack and server temperatures under control in under 3 minutes.
  • b. Physical installation of the HT-510-T is 30 minutes or less with no special tools required.
