Spares and Extras
EcoCoolers have very few mechanical parts compared with refrigeration technologies and are simpler to maintain. All coolers come with a preprogrammed test sequence which will highlight faults with core components to allow for easy diagnostics. EcoCooling spares for all units are available ex-stock. A spare parts list can be requested from firstname.lastname@example.org.
Common CREC Spares:
Effective control of the volume flow rate of the various air streams within an EcoCooling system is essential to its successful function. The range of dampers offered by EcoCooling has been specified so that they offer the required flow regulation and integrate easily into CREC controllers. Features offered include:
- Tip Seal Blades – minimising air leakage between damper blades
- Sealed Blade Carriers – minimising air leakage between damper blades and the damper frame#
- Spring Return Actuators – ensuring rapid response in case of emergency or power failure
EcoCooling are also able to provide fire rated dampers, but these should not be used alone for volume flow control in a mixing system. The ECT range of units has integrated intake and recirculation dampers. An additional exhaust damper is recommended in general and is required when the units are used within a system using either backup air conditioning or fire suppressant gas.The ECP range of units require dampers to control air intake, recirculation and exhaust air flow rates when included in a system that requires attemperation.
When fresh air is used in a sensitive environment there can be a risk of either particulate or gaseous contamination. The quality of the air in the locality of the data centre can affect the feasibility of the use of fresh air.
The ECT units have inbuilt filtration. The ECP units require filtration to be built into the ventilation system design. EcoCooling stock a variety of filters in different grades up to F7. This range has been specially selected so they are easily incorporated into our systems.
- Pre-filter jackets: These fit around the outside of the external coolers, prefiltering the supply air.
- Cartridge filter: These can be fitted as part of the attemperation loop to ensure recirculated air is also filtered.
- Filter bags: These are used in the ECT10800 units to filter both supply and recirculated air.
- Dual Filtration: Air intake filtration (pre-filter jackets) is designed to eliminate potential contamination from external air, prolonging the lifetime of the cooling pads. In addition cartridge filters can be used in either ducting or as replacement ceiling tiles to filter the recirculated air.
The Small EcoCooler is provided with inbuilt fans as standard.
Noise Controls: For installations where there are noise restrictions the fan can be upgraded and anti vibration mounts added to the unit before dispatch.
All ECT units and the Large EcoCooler are supplied with inbuilt EC fans. They are also specified by EcoCooling for any ECP CREC systems as standard. EC Fan models most commonly used in EcoCooling systems are available ex stock. Electronically commutated (EC) fans are driven by a micro-controller instead of a traditional AC motor. The technology provides the following advantages:
Electronically commutated (EC) fans are driven by a micro-controller instead of a traditional AC motor. The technology provides the following advantages:
- Increased speed control: EC technology enables continuous adjustment of the fan speed to meet the cooling demands of the data centre. EcoCooling control systems are designed to take advantage of the energy savings which can be gained by reducing fan speeds.
- Low power usage at partial loads: The power used by a fan is proportional to the cube of its speed. Operating the fan at half speed means it will only use an eighth of full speed power. Operating the EcoCooling system at half speed reduces the fan energy use by over 85%.
Plenums are used as a standard solution for air distribution in industrial installations. EcoCooling stock a number of plenums which can be incorporated into system designs.
Some installations require a colour coating of units due to external building regulations or to improve the installation aesthetically. Both the external and internal ranges can be colour coated when a RAL number is provided.
