Technical Overview

Cannon Water Cooling solutions work on the air to water heat exchanger principle:-
Warm air from a cabinet, room or aisle is forced through a heat exchanger fan coil by high efficiency fans.

system water chiller(s) (not included).
The heat in the warm air will naturally dissipate into the fins of the coil as they are colder than the air, by this process the heat is

The now cold air is carried out of the coil and blown into the cold aisle or cabinet.
The water that has been warmed by the heat exchanger coil is returned to the main system chiller loop though a variable flow control valve
(optional automatic).

Performance of the system is dependant on many climatic and environmental conditions:-
The Computer room should be sealed from outside heat sources and fresh air minimised within reason.

from the equipment fans open.

All unused rack space should be blanked off.

Cannon computer rack cabinet / aisle water cooling systems are not traditional air conditioners, they do not regulate humidity. In humid
atmospheres they will remove water vapour as condensate when the humidity level is high.
The condensate drain should be run to a normal gravity drain sump. An optional condensate pump may be fitted if required.
In some situations the room humidity may be too low, and static electricity may cause a hazard to persons and equipment.

The climate inside a data center should meet the standards set by ASHRAE:-

Thermal Guidelines for Data Processing Environments, Second Edition, ASHRAE 2009b
ISO 14644-1 Class 8 dust and particulates standard should also be met.

Cannon equipment is designed and built to comply with BS EN60950 and the low voltage directive / SELV where appropriate.
Any installations must meet local building and electrical supply regulations where applicable.
