External Product Range (ECP)

ECP wet boxes can be installed externally or inside a plant room. The ECP60-01 is supplied as a down discharge unit with top and side discharge configurations available. The ECP60-02 is supplied as a top discharge unit with a down discharge configurations available.

Filtration: EcoCooling offer a number of filtration options for both supply and recirculated air. Filtration is avaliable up to EU7 grade for use in installations using ECP units.

Fans: ECP wetboxes should be fitted as part of a mechanical ventilation system. Various sizes and configurations of EC fans are stocked for use in ECP installations.

Dampers: EcoCooling stock a larger range of dampers which are compatible with our control systems.

Internal Product Range (ECT)

The ECT range of coolers are designed to be installed internally. The units come complete with EU4 filtration, supply fans and dampers. Multiple configuration options allow for air to be supplied either directly, through duct work or raised floors.

Filtration: ECT products include EU4 grade filtration for both supply and recirculated air.

Fans: ECT units are supplied with in built EC (Electronically Commutated) supply fans. Additional extract fans may need to be purchased depending on the installation.

Dampers: ECT units have in buult recirculation dampers Additional supply and fire dampers may be required depending on the installation scheme.

How CRECs Operate in Different ConditionsCold ambient temperatures: Attemperation mode: Hot exhaust air is mixed with cold external air to supply air at a constant temperature.

Hot ambient temperatures: Cooling mode: On hot days, air is passed over wetted cooling pads. The air temperature is reduced by the evaporative cooling process.

The cooling process: All of our products contain evaporative cooling pads . Water is brought into the cooler from the mains water supply and is pumped up to the top of the unit using a circulation pump. The water is then dispersed over the Celdek pads using a water distribution system which allows the water to flow continually over the pads.

The pads become saturated, air is drawn through and the water evaporates causing the air to cool. The cool air is then ducted round the building by means of supply and extract fans.

Products, Controls and Commissioning Service

Evaporative cooling is a completely natural alternative to air conditioning, they work as part of a mechanical ventilation system and can reduce cooling costs by up to 90% when compared to the refrigeration alternatives. EcoCooling CREC products can provide supply air temperatures of under 25°C all year round in the UK. Increased fan efficiency means PUEs of less than 1.05 have been recorded in buildings using EcoCooling products and controls.

Advantages of using direct evaporative cooling

• Requires ~90% less energy than AC alternative• No refrigerants, completely natural cooling process• Low running and maintenance costs• Low carbon and energy use • Exploits the maximum amount of free cooling available• Low energy use even at partial population• Qualifies for Salix funding

Why use EcoCooling CREC products and controls

• Experienced innovators in fresh air solutions and controls

• 350 IT installations worldwide• Modular systems can reduce capital cost• Patented products and controls• UK manufacturers, coolers and spares all ex-stock• Worldwide remote commissioning

EcoCooling’s commissioning service is delivered once the CREC installation has been completed. The service optimises the performance of the mechanical system and adjusts the control set points and parameters according to the client requirements. The commissioning service can be completed remotely.

Depending on the installation and operation of CREC systems, return on investment can be achieved in under a year. Below are operating cost calculations for some of our products. For cost calculations for your project and location please contact us directly. Costs used: Electricity at 10p/kWhr. Water £1.00 p/m3. London location. 24/7 usage. ΔT=10°C

What is ΔT? In the above calculations and table to the right ΔT signifies the heat gain over the servers (the difference between supply and exhaust temperature). This can be used to determine the cooling capacity of our coolers and systems.
