Jensen Ventilation with head office and production in Malmoe, Sweden, is part of the AB Chr Jensen group. The company was formed in 1879, and is one of the oldest companies in the world specialising in processing PVC-coated material. The group produces and finishes various types of PVC-coated fabric. It manufactures storage structure halls, tarpaulins, party marquees, protection against weather and flooding, truck covers and a wide range of tailor-made products. Since the 70s, Jensen Ventilation has been producing and marketing flexible ducting systems. The products are represented by agents around the world.

Together with Bends, Y- and T-branches and cones, which are made out of extremely solid fabrics with welded seams, Jensen Ventilation offers a complete and dependable ventilation system.

Manufacturing methods Jensen Ventilation is using a welding system, based on a superior welding method developed in our company and patented in 1981 in Sweden. The advantages with this superior welding system is partly a 40 mm wide welding seam giving the seam almost the same strength as the material itself.

Materials Long experience and major research work enable

us to produce fabrics with minimal elongation of

the base fabric. The result of this development is

to be found in our today’s qualities JP 551,

JP 651 and JP 753, which will give you less

elongation in the length direction and practically

no extension of the diameter of the ducting. All

qualities are fire retardant and we also supply

antistatic alternatives.

The ductings are as standard available in dimensions from 300-3000 mm diameter, with 100 mm interval. Lengths 10, 20, 25, 50, 100 and 200 m are available.

For connecting, Jensen Ventilation offers three options:

Changes in air speed will result in an alteration of the dynamic pressure, to the disadvantage

for efficient ventilation with loss of energy as a consequence. A straighter and tighter tube in

the coupling area will lead to better results at the end of the ventilation canal and reduced

costs for high kW performance of the fan and reduced operative expenses on account of

energy-saving.

- A True Breath of Fresh Air

1. Traditionally with a galvanized coupling clamp outside and one or two steel rings welded in the end of the ducting.

2. A special made zip-

connection; very strong and durable.

3. Strong and easy-handled

velcro connection.

Suspension The galvanized steel hooks are packed in boxes and placed together with ducting. The hooks are to be hooked on a longitudinal steel wire on the tunnel ceiling. The suspension is constructed in such way, that if there would be an extraordinary force on the ducting, the steel hooks will break and leave the reinforcements without damage. Steel hooks are available as spare parts and can easily be reassembled on the ducting.

JP Jensen Ventilation Repair Kit

Incl. Repair fabric, PVC-glue, glue brush,

glue spatula, cleaning, needles, thread and

suspension hooks.

(extra: hot air gun, not incl)

Four methods: 1) Needles / thread 2) Glue 3) Needle / thread & glue 4) Hot air gun

Always have clean and dry fabric to work on. If you sew, use double thread

and choose distance between each thread depended on damage. For better

results, sew “up and down”. This method is for quick repairing and should not

be permanent because of leakage. For better durability and density use glue

after sewing. It is also common to use glue only. When using glue, always have

something on the inside to press against until the glue dries. At the same time

you avoid that the ducting fixative together on the inside.

As extra we can deliver the repair kit with a hot air gun. Repairing with a hot

air gun is the most professional and optimal way to repair ducting. The result is

a strong repair with no leakage. When using hot air gun, always have some

protective base direct under the area you are repairing! It’s very hot, be careful

when using it and protect yourself!

Determine the length of the hole. The repair

sleeve should cover the hole with at least 0,5

meters margin.

Remove the suspension hooks which will be

covered by the repair sleeve.

Hook the hooks from the repair sleeve onto the

suspension cable.

Wrap the repair sleeve over the duct. Make sure

the hole is well covered by the sleeve and the

zipper is at least 0,5 meter away from the hole.

Close the zipper and the repair is finished.

Jensen Ventilation Repair Sleeve

The repair sleeve is a fast and secure tool for repairing holes and tears of flexible ducting. The sleeve is made

from standard duct material and a longitudinal zipper is attached for closing the sleeve. The sleeve is made

approx. 0.5% smaller than the nominal duct diameter which will allow the sleeve to be really tight against the

duct once the duct is pressurized. With the repair sleeve, the repair will be professionally done and the leakage

from any hole will be reduced to a minimum. The repair sleeves are manufactured in standard lengths 1.0, 2.0,

3.0 and 5.0 m. Other lengths will be manufactured upon request.

VENTILATION

GENERAL

The primary objective should be to reduce emissions of contaminants at source and hence reduce the need for ventilation.

Where atmospheric contaminants remain, a purpose-built forcing, exhausting or circulation ventilation system should be employed, depending on the contaminants which have to be rendered harmless.

The concentration of oxygen, dust, toxic or potentially explosive fumes or harmful gases in the tunnel atmosphere should be routinely monitored and steps taken as necessary to ensure contaminant levels do not exceed those laid down by national legislation or guidance. Where a specific work activity known to generate significant contamination, such as shotcreting or welding, is being carried out, local monitoring with additional ventilation as necessary should be undertaken.

In the absence of national legislation or guidance, legislation or guidance from another nation giving contaminant exposure levels should be selected as the base standard. Records of all routine monitoring should be maintained.

As a guide, the quantity of air supplied or extracted from the face should be such that the average flow in the full cross section of the tunnel or shaft should be between 0,3 m/s and 2m/s at all times.

Minimum quantity of air for personnel to be 1,5m3 per minute per man and 4m3 per minute per kW rated power for diesel machines. Additional air may be required for cooling purposes.

Ventilation air entering a tunnel should be free from dust, smoke or other impurity.

Ventilation should be such that in every underground working area, safe and healthy conditions exist and fumes or gases shall be diluted to the extent that they are rendered harmless. A minimum oxygen concentration of 19% should be maintained at all times when persons are at work underground. No-one should remain underground when the ventilation system is not operating.

The wet globe bulb temperature (WBGT) should not exceed 28o C. Ventilation can be used as a means of removing excess heat from the workings.

_______________________________________________________________________________________________________________



To minimize dust generation, wet drilling techniques should be used in a tunnel in preference to drilling machines fitted with appropriate dust collection equipment.

Dust generated during shotcrete spraying should be minimized as part of the mix design process. Other machines and processes creating dust should be fitted with appropriate dust suppression and collection equipment.

Diesel-driven internal combustion machines should be fitted with particulate filters. These machines should be kept in good order and should not be left idling in the tunnel.

In a tunnel with a risk of a potentially explosive atmosphere occurring, safety critical equipment such as firefighting equipment, pumping equipment, ventilation equipment, communications and atmospheric monitoring equipment should be explosion protected as necessary so that it remains operational even when potentially explosive gases are present.

For guidance on selection of duct material see ITA Report # 8

VENTILATION LAYOUT

The layout of the ventilation should be as clear and straightforward as possible.

Ventilation ducts should be kept as tight and straight as possible to reduce air losses and friction resistance.

Reductions or obstructions of ventilation ducts should be avoided.

Booster fans in the ventilation duct should be avoided.

High pressure in ventilation ducts (above 300 Pa) should be avoided to reduce power consumption, air losses, repair issues and induction of heat.

The air velocity at the end of the vent duct should be around 15 m/s to allow the airflow to reach the tunnel front.

A minimal free space of 0,2 m in between vent ducts and loaded vehicles should be considered.

The position of the fresh air intake should avoid the recirculation of contaminants and smoke.
