- Computer Room Evaporative Cooler

0

This is a derivative of the standard CREC DT cooler specifically designed for the cooling of data centres. The air is discharged through the side of the cooler and the attemperation is provided by a patented single damper on the top of the cooler. The CRST has a nominal output of 9,000m3/hr@130Pa external pressure. This is a lower output than the CRDT as it only has 3 sides available for cooling.

Control - A special control system has been designed for use with the CREC which is purchased in addition to the cooler. Each controller can manage up to 6 CRECs and is designed specifically to meet the requirements of each client. Based on a Schneider Crouzet PLC, the controller continually monitors key environmental parameters and then sets damper positions and fan speeds to control the temperature and optimise performance. All key sensors are duplicated and monitored and where refrigeration is used as a back-up this is automatically enabled in fault conditions. For more information on the CREC control system please visit our control section

Water Control - A patented water control system using a 4 probe system prevents excess water usage and ensures that the tank is drained completely to prevent the build-up of bacteria in the sump.

The CREC ST is classed as LOW risk with regards to Legionella but in line with health and safety regulations a full legionella risk assessment can be provided when the units are commissioned should this be required.
Availability - stocked item lead time 5-10 days.
