Product information
The RackChiller range of products provide cooling to rack mounted IT equipment in data centers.
They have been designed with energy efciency and high equipment density in mind.
They can replace the traditional approach to data center cooling or work alongside existing data center
designs as it is modular and scalable.
Designed to be connected to existing or new external cooling plant, RackChiller units are made up of a heat
exchanger, fans for airflow and a Centralised Management System (CMS) which oversees the control and
interfaces with BMS or other management systems.
The CMS lies at the heart of the RackChiller In Row solutions, keeping the room ambient temperature
controlled locally and at cabinet level. It automatically adjusts the fan speed, flow rate and, if necessary,
the output temperature resulting in a consistent delivery of cooled air into the data center with no operator
intervention. The whole process can also be overseen and controlled at individual cabinet level, room level
and remotely via any of the industry standard communication protocols. Water cooled variants of the In
Row system keep water above dew point which keeps the system free of condensation.

Important safety information
Safety instructions
• The RackChiller Systems contains no user serviceable parts inside.
• The RackChiller system requires an external means of isolation for both the incoming power and
cooling supplies.
• Protect the power cord from being walked on or pinched, particularly at the hinge, plugs and outlets.
Should a power cord become damaged, isolate the system and remove from service until an
appropriate replacement can be sourced and tted.
• Do not block any ventilation openings.
• Refer all servicing to qualied personnel experienced with these types of installations.
• Should a fault occur with the product, immediately isolate and disconnect the incoming power.
• This unit has a dual supply – isolate both supplies before carrying out any work. Pull out both
cables to shut off. The end user is to be guided on other methods of isolation.
• Always ensure the machine is level when in use.
The units must be installed vertically on a level, dry floor.
• The machine should be used as provided and should not be tampered with or altered as the
machine contains inbuilt safety systems which could be compromised by any interference.
• This equipment is designed to be installed in an ofce or data center environment and is for indoor use only.
• The installation and operation should be conducted in accordance with local regulations and
accepted codes of good practice.
• Adequate ttings to be used – they must not be to the detriment of any UL or local standard.
• The appropriate Personal Protection Equipment (PPE) should be worn at all times.
