Operational Instructions

1 Description and Specifications

Heat management in Underground Mining continues to be one of mining’s foremost risks to both the health and

safety of mine workers and the operational stability of the mine.

This compressed air driven, portable “air conditioner” can deliver super cooled additional air to a workplace.

“THE COOL TUBE” Developed and manufactured for the intended use of –

Mining activities such as Longwalls, Development units.

Additional ventilation to frictional ignition areas without gas recirculation.

Confined space locations such as vessels, dragline tubs and hoppers.

Fixed equipment and infrastructure cooling.

Surface exploration drill rig operator and recovery tent cooling.

Positive pressure air conditioned refuge chambers, COBs and crib areas.

Marine Engineering Spaces and Tank Compartments.

Air condition containers storing items such as chemicals and electrical parts.

Any hot and or humid work area with access to compressed air.

*The Cool Tube cold end outlet air temperature is a linear temperature drop from the compressed air inlet

temperature. The Cool Tubes have been modelled on an average compressed air temperature of 28°C at 7 Bar giving

a linear drop of approximately 23° C -25° C , to give the best volume of cold fraction air against warm air discharge.

Variations to this can be made upon request.

2 The Cool Tube User Instructions

1. Remove shaft locking pin & swivel mount arm of cooling tube to desired angle. Replace pin.

2. Connect compressed air supply and secure as per site standard.

3. If installing a 2” diameter hose extension (Recommended for maximum dB reduction) on the warm air

discharge ventilated heat shield, remove the round warm air discharge end cap that is tethered to the unit.

Ensure that the hose length does not have any “dips” that could reduce the efficiency of the cool tube, by

allowing water from the compressed air supply to be trapped, which will in turn inhibit the escape path of

the warm air. A baffle can be installed or a restriction in the end of the bull hose to reduce any residual

noise. Ensure that the bull hose covers all of the slots on the warm air discharge end of The Cool Tube. Keep

the radial 3mm holes around the warm air discharge clear and free of build-up.

4. Connect earthing cable clamp to grounded location if required by site risk assessment. The Cool Tube is fully electrically bonded and no non-conductive components used to ensure no static generation in the units, however an earth clamp has been added as a feature as a secondary control when used in hazardous environments.

5. Turn on compressed air supply. Cold air supply should be immediate; however steady state temperatures

may take up to 2 minutes to settle. If installing a flexible extension hose on the cold end, ensure that cross

sectional area of the hose or ducting is equal to or greater than the cold outlet of “The Cool Tube”. A back

pressure of greater than 4 PSI on the cold end will reduce the performance of “The Cool Tube” by as much as

3°C.

6. The Cool Tube can be flushed with pressurised water for internal cleaning if required due to compressed air

contaminants.

3 Extension Adaptor User Instructions

1. Screw male end of adaptor into nut on cooling tube adjustable arm.

2. Screw female end of adaptor onto rib bolt or magnet or mounting point.

3. Tighten firmly

3 Muffler Extension User Instructions

1. Screw male end of muffler extension into female 1” BSP exhaust fixed muffler.

2. Tighten firmly.

5 Magnetic Base Adaptor User Instructions

1. Remove shaft locking pin & swivel mount arm of cooling tube to desired angle. Replace pin.

2. Screw cooling tube onto mag base adaptor.

3. Ensure ferrous item to act as the mounting plate is clean and flat otherwise performance of the magnet

will be affected. Holding strength depends on material thickness. Mounting plate thickness >5mm is

ideal.

4. The magnetic base is not a lifting device and no other items are to be supported by it.

5. Place mag base on clean surface, turn and engage the magnet lever into the locked position.

6. Ensure to connect safety tether from mag base to fixed location on mounting point. The tether is

intended only to support the fall of the cooling tube due to poor magnet mounting technique and

should not be used for any other manner.

7. Test connection strength while tethered before leaving fully unattended.

NOTE: The Cool tube will continue to function as intended for an indefinite amount of time if cared for,

used as intended, not tampered with and used as directed.
