Application:
ESKS integral light/Sight Glass units have a quick release closure, so that they are a combination of charge/access port and light/Sight Glass. The integrated luminaire illuminates the internal of boilers, tanks, bunkers, silos, mixers and other vessels in all non hazardous areas. SKS type Sight Glass ports are of the same design, except they have no luminaire. Both types are suitable for food processing. Usually these units come with a weld flange, but for flat vessel walls they can also be installed with a bolt-on flange.
Safety Precautions:
Warning: The unit must never be opened before the pressure inside the vessel is reduced to zero!
Protection:
When correctly fitted, dust and waterjet proof to IP 65, EN 60598.
Ambient Condition Operating Range:
The unit is vacuum proof and resistant to:
pressure up to
-
8 psi, type SKS/ESKS 225
-
15 psi type SKS/ESKS 150
max. vessel temp:
ambient temp:
Electrical Data:
power supply 24 V or 120 V, halogen lamp 50 or 100 W, 2-pin socket GY 6.35.
Transformer:
Transformer can be supplied as extra item.
Combinations:
ESKS and SKS units can be combined with SW I type wipers (see data sheet 02.01).
Mechanical fitting:
The unit comes ready assembled. Before welding, the Sight Glass frame and the hinge assembly should be removed from the base flange. Check desired position i.e. direction of swing. The lug and hinge assembly holes are not identically spread. The weld flange must be welded into the vessel wall free of distortion; bolt-on flanges require an entirely flat vessel wall.
- Lumiglas luminaire (only with ESKS)
- luminaire with Sight Glass
- weld flange (resp. bolt-on flange with drilled holes)
- closure knob
- closure lug
- hinge assembly
- fastening ring (only with SKS)
- 'O' ring seal
Lamp Change:
Caution: Since the unit must be opened for lamp change, reduce pressure in the vessel to zero, and put vessel out of operation. Check vessel for pressure and temperature before opening a Sight Glass fitting!
