The primary function of the CO2 Absorption Unit is to remove carbon dioxide from the atmosphere in a submarine in the event of an emergency and to deliver purified air with a reduced CO2 content.

Air purification is initiated when the electric motor within the unit is activated by a crew member. The motor drives a fan which draws carbon dioxide contaminated air through four soda lime canisters. Purified air is then delivered into the submarine either through tubing, or via the submarine's ventilation trunking.

Power is supplied to the unit via a power supply regulator which runs off the submarine's main battery. The regulator controls the amount of purified air delivered into the submarine's ventilation trunking. Should the submarine's main battery supply be unavailable, i.e. in an emergency situation, a changeover switch operates to connect the unit to the submarine's sea water batteries.

	Unit design can be adapted to fit any size navy regulation soda lime cannister.
	Vibration and noise levels are kept to a minimum so the unit is virtually undetectable by an enemy submarine.
	Each unit is lightweight (262lbs) which makes it very easy to move for submarine maintenance or refurbishment purposes.
	Ease of operation means that crew require very little training.
	Units are extremely reliable and require little or no maintenance.

We provide a full training programme to appointed navy representatives, operations manuals plus spares and on-going maintenance support. Bryant Symons' engineers can undertake yearly checks of each unit as part of our after sales service if requested by the customer.

The CO2 Absorption Unit has historically been used on military submarines, but can also be adapted for use on non-military submarines (i.e. for diving purposes). Other potential uses include providing purified air in the event of an emergency for underground facilities such as tube or metro systems, long distance tunnels, and recreational caving facilities.
