EC Fan In-Floor Cooling Unit - raised access flooring contractors

Description

Airflow Management Solutions

Air direction raised floor is able to blow the cold-blast air to cabinets angularly , almost eliminate the the side stream to save the energy efficiently.

Variable air volume of EC fan supply the air to heating load directly and respond timely according to the sensor monitoring device installed in cabinets.The assistance module provide the modified scheme to owner who have installed the raised floor to deal with investing vast fund to retrofit the ground facilities in the use of high-density cabinet. We provide a new concept in the design of raised floor to facing the challenge of introduction of new technology and the continuously developing of technology and infrastructure in data center.It involves in the use of extreme high density cabinet , variable change of heating load in cooling and economy of investment. The most important is that in-floor cooling solutions can be easily applied to the renovation of computer room facilities and new construction. So, we provide a new perspective to solve the problem of cooling in data center .

Airflow & Fan Control

The work is done by a single EC axial fan. Its air volume is variable, so it speeds up as the temperature sensors in the cabinets report a rising load and eases back when the load falls away. Soft start keeps the initial draw gentle each time the unit comes on, and because the fan is a single axial structure it also maintains a minimum ventilation rate through the panel when the unit is not boosting. That is the practical side of raised floor cooling: airflow follows the load under each cabinet instead of being pushed across the room at one fixed rate.

Installation & Commissioning

Choose the panel opening that serves the hottest cabinets on the row and agree which way the unit should face before anything is lifted.
Check that the opening matches the panel grid in your data center raised floor, and that the airflow path to that position under the floor is clear.
Lower the unit into the opening. It is a floor panel in its own right, so it sits level with the surrounding tiles.
Bring the power feeds and the sensor leads from the cabinets to the unit, keeping the cable route off the airflow path.
With the room unloaded, confirm the discharge is landing on the cabinet intake before the floor is handed over.

Retrofit & Operating Economy

Retrofit without rebuilding the floor: the unit occupies a panel position, so an existing raised floor can be upgraded for denser cabinets without renewing the ground infrastructure underneath.
Staged spending: each unit works on its own, so a room can start with the positions that run hottest and add more as density grows, instead of cooling the whole hall to the standard of its worst row.
New-build planning: on a new fit-out the units are specified alongside the floor layout, so airflow, power and sensor routing are agreed before the first tiles go down.
Part of a wider system: this is one element of our raised floor solutions and it works with the panels, tiles and underfloor airflow already in the room.
Supplied for project work: we supply these units to raised access flooring contractors and to in-house facility teams running a staged upgrade, with both models available for a single fit-out.

Scale & Supply Capability

As a raised access flooring supplier, we cover a complete system rather than single items: pedestals and stringers, antistatic PVC and HPL tiles, PVC skirting, panel lifters and cutting blades, air diffusers, brush grommets, flip outlet boxes and in-floor cooling units. Our structural components suit OA, steel, wood core, calcium sulphate and aluminium raised floors, with pedestal heights from 70 to 1500 mm. Specifications such as stringer size and thickness can be customised to your project, so contractors can source compatible components, installation tools and cooling accessories from one supplier for data center, computer room and commercial fit-outs.

FAQ

Q1. How does the unit react as the load in a cabinet changes?

Sensors in the cabinets feed temperature back to the unit, and the fan is set to move through three stages: a start temperature at which it begins to run, a full-speed running temperature, and an alarm temperature that flags a problem. In a data center raised floor, load moves between hosts through the day, so all three settings are tuned to the site rather than fixed at the factory. The unit then responds to the room's real behaviour instead of running to a schedule.

Q2. Can several units be monitored as one group?

Yes. Each unit carries an RS485 or LAN interface and works with the Modbus communication protocol, so a row or a whole room can be read as one group. Group control is usually planned for a later phase, which means addressing is preferably agreed while the first units are being commissioned. Tell us how the room will be managed and we will confirm the point list before the wiring goes in.

Q3. What happens to the airflow if the mains supply fails?

The air temperature controller takes two feeds, one from the grid and one from the UPS, and switches to the UPS automatically when the grid drops. The fan keeps moving air across the load through the event instead of stalling, which matters most in a room running close to its thermal limit. Both feeds are part of the unit's power arrangement and the changeover is checked at commissioning.

Q4. Where do the temperature sensors go, and how many can one unit take?

A single controller can take one, two or three temperature sensors. They are the monitoring devices placed in the cabinets themselves, so the unit reads the temperature where the equipment actually sits rather than at the panel. That lets one unit watch more than one cabinet, and the number you fit depends on how many positions it is asked to serve.

Q5. What routine attention does the unit need?

Treat it like the rest of the floor. Keep the panel face and the fan free of dust, tape and debris so air can move freely, and leave the underfloor path to the position unobstructed. During normal inspections, check that the sensor leads are still fixed inside the cabinets and that the display reads as expected, since the controls sit level with the floor and are easy to reach.

Q6. How is this different from a standard airflow panel?

A standard airflow panel releases plenum air straight up and depends on the pressure under the floor to push it through. This unit uses its own EC fan and a 15° angled discharge to aim cold air at the cabinet intake, where it does useful work, and it trims the side stream that otherwise drifts into the aisle. That difference is what counts in raised floor cooling at high density.
