The domnick hunter MAXI
Regulation 2, not as a pressure vessel, but as a pressure containing component, such as equipment that is not
fabricated or welded (e.g. filters, pressure regulators, refrigerant dryers).
The period of inspection under the regulations is to be decided by the owner of the equipment, but domnick

E) DESICCANT SAFETY INFORMATION
Instructions for use of 'SNOWSTORM' filler
domnick hunter 'snowstorm' fillers must always be used when recharging PNEUDRI compressed air
dryers with DRYFIL
THE "SNOWSTORM" FILLER
To ensure optimum performance from PNEUDRI, it is essential to 'snowstorm' fill with DRYFIL
material, recharging using a genuine domnick hunter "snowstorm"
filler.
The filler controls the flow of desiccant material to achieve maximum
packing density, and avoids channelling and fluidisation, preventing
attrition and rapid deterioration of the desiccant bed.
USE OF THE "SNOWSTORM" FILLER
After removing the expended desiccant, place the filler on top of the
empty dryer column, using the pins in the base for positive location
over the centre of the column chamber.
Pour desiccant into the filler ensuring continuous filling is maintained
where possible. As the chamber becomes full, it is possible to monitor
through the perspex base the quantity of desiccant required to
complete the filling process without causing spillage.
When re-charging a Heat Regenerative PNEUDRI with desiccant,
ensure the heater wires are positioned under the slot in the base of the
filler, and positively located away from the filling area. This ensures no
obstructions are created within the chamber, and allows a continuous
flow of desiccant.
IMPORTANT NOTE:
To ensure reliability, always refill PNEUDRI with DRYFIL
