ECT10800 Internal Evaporative Cooler

ECT10800 Internal Evaporative Cooler

Features

The ECT 10800 is part of EcoCooling’s internal evaporative cooler range. At it’s design flow rate of 10,800m3/ hr it can service a cooling load of 35kW with a COP of 39. The coolers compact size means is easy to install and maintain making it the ideal option for larger server or telecommunications rooms. The ECT range is also avaiable in a 5400 model for smaller IT loads (~15kW).

  • Water supply and drain through the sides of the unit
  • 3~ power supply
  • Extract fan or non return damper
  • Additional temperature sensors (2 included)

CORE FEATURES

Controller

The cooler is controlled by a Carel PLC which can be linked into standard BMS and fire systems. Software
can be managed through an ESCROW account. The control system comes with a GUI (touchscreen) as standard. Remote monitoring and control is also available through a wallmounted touchscreen GUI.

Dampers and Temperature Control

The cooler uses a dual damper attemperation system to supply air at a constant temperature. Hot air is recirculated back into the supply airflow to maintain the desired set point. Once the external temperature
exceeds the set point then the cooling function is enabled. The recirculation damper is situated on the top of the unit. The fresh air intake damper is situated on the back of the unit.

Fan:

A Ziehl-Abegg 630mm FE2owlet ECblue fan drives the airflow. Use of EC fans results in significantly quieter and more energy efficient operation than AC alternatives.

Filtration:

The airflow is subject to EU4 filtration both at the fresh air intake and at the point of supply.

Plinths:

The cooler supplies air through a plinth at its base. The standard plinth has louvres on 3 sides and is designed to deliver air from the front. An alternative plinth can be supplied if required which allows for a ductwork connection.

How it Works

Ventilation Mode

Internal Evaporative Cooler from Ecocooling

Cooling Mode

Internal Evaporative Cooler from Ecocooling

In ventilation mode, the supply temperature is met by mixing warm room temperature air with the incoming cool air using the attemperation damper. The level of attemperation, or mixing of recirculated warm air with fresh air, is controlled by the damper.

In cooling mode, the unit can operate with or without attemperation to achieve the required supply temperature. In this mode, the water circulation system is in operation and the cooling pads are wetted. The evaporation of water from the pads results in a reduction in air temperature.

WATER SYSTEM & LEGIONNAIRES

EcoCooling's process control system ensures the risk of legionella is kept to a minimum. The risk factors for Legionnella formation have all been addressed in the design and controls of the ECT units.

COMMISSIONING AND SERVICING

EcoCooling offer a commisioning service after installation of the ECT unit. It is recommended that the cooler is serviced every 3 months. Standard EcoCooling components are used, which are avaiable exstock. Please contact sales@ecocooling.org or 01284 810586 for more information and installation examples.
