Introduction

1. Introduction

This manual contains guidelines for transport, installation and service of the Sabroe enclosure

and instructions on how to ensure access to the equipment inside the enclosure.

Transport

2. Transport

2.1 Transport

The enclosure is top heavy. See the centre of gravity location on the specific GA drawings.

2.2 Lifting the enclosure

A crane, which can lift the stated weight of the enclosure, is required. Further, a lifting yoke

must be used to make sure the panel plates are not damaged when lifted, see Fig. 1

Fig. 1

Transport

2.3 Fixing the enclosure during transport

Place the enclosure on straws and fasten it by lashing straps to prevent it from tipping during

transport, see Fig. 2.

Fig. 2

2.4 Enclosed trailer

If there is a risk of salt from the road or somewhere else, the enclosure must be transported in

an enclosed trailer.

2.5 Enclosure preparations

The door panels must be stabilised during transport. By inserting blocks underneath the doors

as shown in Fig. 3 and Fig. 4, the hinges are protected from damage.

The threaded plunger from the safety relief system should be closed with tape or a plug during

transport, see Fig. 5

Installation on site

3. Installation on site

3.1 Lifting brackets

When the enclosure is placed on site, the lifting bracket should be disassembled and stored, if

needed. See Fig. 6.

Fig. 6

3.2 Safety relief system

Remove the plug or tape to assemble the rest of the safety relief system with the included pipe

fittings. The opening should point down, see Fig. 7 and Fig. 8.

Installation on site

3.3 Electrical connection

The enclosure is supplied with a reinforced panel for cable lead-in. The exact location of the re-

inforced panel is shown in the GA drawing, see also Fig. 9. The panel section is reinforced with

a glued double outer plate to mount cable glands for cable entry. The construction of the rein-

forced panel is illustrated in Fig. 10.

Fig. 9 Fig. 10

3.4 Settings for heating panels

The heating panel secures against frost. The turn-on temperature should be set at 5°C and the

turn-off temperature at 15°C.

To install the thermostat, follow instructions in ”Nobø NCU-2Te” manual, see Fig. 11.

4. Service of the plant and enclosure

4.1 Safety

Safety box

The enclosure is classified as a machinery room. As the room is not part of a building, some re-

quirements can be waived. There is light inside and an emergency exit light above the doors.

Manual control of the fans, main switch and emergency stop is possible from the front of the

safety box. It has indicators for Fan running, Gas detector (low and high alarm) and Tempera-

ture from inside probe.

Fig. 12

For more specific information, please see the electrical drawings in the appendix.

4.2 Access for service

Fig. 13 - Fig. 16 show the access options for a specific “6 high” version enclosure. The number

of sections and the positioning of doors may vary depending on the plant inside. However, in

general, access will be possible as shown in Fig. 13 - Fig. 16 through the doors or demount-

able panels.

Opening the doors

The doors provide the main access. They are locked in the top, middle and at the bottom. Use

the supplied square key to unlock the three latches, see Fig. 17.

Fig. 18 shows how the open door provides access to part of the compressor and the WHC

system.

Access through the panels

For extra service access, the panels can be disassembled by loosening the pan head screws,

see Fig. 19.

Fig. 19: Loosen the pan head screws and remove the panels. Press your hand against the panel when loosening the last screws

to make sure it does not tip over on you.

4.3 Sensors

Two sensors are mounted at the top of the enclosure: one for ammonia and one for ventilation.

Fig. 20 Fig. 21

Fig. 20 shows the ammonia detector, which activates the ventilation system at certain quanti-

ties (350 mg/m3starts a prealarm) and turns off the plant at other quantities (21,200 mg/m3

starts the main alarm).

Fig. 21 shows a temperature sensor, which starts the ventilation system at 35°C.

4.4 Ventilation

Check regularly that the ventilation filter is not clogged with dirt. The filter is accessible from

the inside of the door panel, see Fig. 22 and Fig. 23.

Fig. 22 Fig. 23

4.5 Oil trap for protection of safety valves

Check regularly that the oil trap has oil. The green ball should float in the sight glass, Fig. 24.

The oil trap prevents moisture from getting into the safety valve and cause jamming. If the oil

trap is empty, check if there has been a pressure relief from the vessels. If necessary, there is

a nipple for charging and one for draining oil, see Fig. 24.

4.6 Siren and alarm

Do NOT open the door, if the siren and alarm are on.

If the siren and alarm are on, gas has been detected. The detection will also activate the venti-

lation system to let fresh air into the enclosure and ensure that the gas concentration cannot

cause explosion hazard.

When a leak is identified, it must be determined whether it is so severe that it requires full

emergency procedures, or if it can be contained by trained personnel on site.

The siren and alarm are placed on the outside of the enclosure over the double door in the end

or over the control box at the front.

Fig. 25

4.7 Access for major repairs or service

If major repair is required, the entire front can be demounted. Pay attention to disassembly of

panels with pipe penetration as they will require new insulation and covering at the pipes. Also

be aware of the three-part panel section with the control box, which is not optimal to disassem-

ble because of wires etc.
