Product and documentation changes

SKOV A/S reserves the right to change this manual and the product described herein without further notice. In

case of doubt, please contact SKOV A/S.

Date of change appears from the front and the back page.

In case of misoperation or improper use, cooling systems can result in production loss or cause

loss of lives among animals.

SKOV A/S recommends that cooling systems be mounted, operated and serviced only by

trained staff and that a separate emergency opening unit and an alarm system be installed as well

as maintained and tested at regular intervals, according to SKOV A/S’s terms and conditions of

sale and delivery.

Qualified personnel must perform installation, service and fault-finding of all electrical

equipment in accordance with the applicable national and international standard EN 60204-1

and any other EU standards that are applicable in Europe.

The installation of a power supply isolator is required for each motor and power supply to

facilitate voltage-free work on the electrical equipment. SKOV A/S does not supply the power

supply isolator.

Note

the express written permission of SKOV A/S in each case.

• SKOV A/S has made reasonable efforts to ensure the accuracy of the information contained in this

DA 100B HD Pad Cooling

1 Product description

DA 100B HD pad cooling is applied for cooling of large air quantities in tunnel ventilation systems. Fresh air is

directed through pads by means of negative pressure in the house. When cooling is required, the pads are kept

moist with water, which circulates from lower gutter to the top of the pad. Pad cooling can be mounted on the

wall or on the floor.

Pad cooling DA 100B HD is specially designed for cooling in hot and dry climate zones (zones with high

cooling potential). This is a result of optimization of the water amount and cooling on-time, which creates a

uniform cooling across the pads.

The system exists in 2 versions:

1. The water performance is aligned to 9 liter/min/meter pad. (System 1)

2. The water performance is aligned down to below 9 liter/min/meter pad. (System 2)

DA 100B HD Pad Cooling

2.2 Safety guidelines - intended use

These Operating Instructions include the most important information in connection with operating the pad

cooling system in a safe manner.

The relevant guidelines for the prevention of accidents as well as other generally recognised

technical safety and medical regulations for the workplace must be observed.

Check that the safety and functional equipment works safely and correctly:

• prior to start-up

• at appropriate intervals

• after modifications or maintenance.

The specifications outlined by the water and energy utility companies must also be observed.

The system is exclusively intended for cooling/air-conditioning. Usage for other purposes is not intended, like

e.g. pumping other liquids than water. The manufacturer/supplier is not responsible for damage resulting from

this. The user is solely responsible for the use.

To the intended use also belongs the attention of the manual and the adherence to of the maintenance

conditions.

2.3 Electrical system

Qualified personnel must perform installation, service and fault-finding of all electrical

equipment in accordance with the applicable national and international standard EN 60204-1 and

any other EU standards that are applicable in Europe.

The installation of a power supply isolator is required for each motor and power supply to

facilitate voltage-free work on the electrical equipment. SKOV A/S does not supply the power

supply isolator.

Mount the pump according to the supplier instruction manual.

The pump must be shielded from direct sunlight (50°C).

Mount the frequency converter according to the supplier instruction manual.

Note that the frequency converter must be placed next to the controller.

All tasks extending beyond the framework of system maintenance may only be carried out by qualified

personnel.

Always isolate the power supply when working on the device and secure against unauthorised reactivation by

another person.

Examine electrical cables for visible damage prior to commissioning.

Replace any damaged lines before putting the device into operation.

Damaged or destroyed plug devices must be replaced by a qualified electrician.

Covering electrical components can give rise to heat concentration with high temperatures which can in turn

destroy the equipment and cause fires.

3.4 Opening for pad cooling

The following measurement are required to make the

opening in the wall:

• Minimum 340 mm from level floor.

• Height of opening = Pad height minus 115 mm.

• Length of opening = Pad length minus 50 mm.

It is important that the vertical sides are

perpendicular to the horizontal sides.

• Use a square to make the sides perpendicular.

• Use a chalk line as guide when cutting the

opening.

Make sure that the edge of the opening are covered and waterproof before mounting the pad system.

Following measurements must be done:

• Make a horizontal chalk line 340 mm from the row of

openings along the edge.

• When you mark out for bracket screw holes, the base

of the bracket must follow the chalk line.

• Mark out for position of the supply unit to start with.

See below if necessary.

• Hereafter, there should be an interval of max. 750

mm between the brackets

• End brackets must be placed with a distance of 100

mm from the end of the opening.

• Mount the brackets for the supply unit in the desired

position, in that way the water gutter follows a

horizontal line.
