Water cooler (chiller) 94/09/CE ATEX EExp
This
is a range of Recirculating Water Coolers (R.W.C.) ;Recirculating Water
Coolers Heater (R.W.C.H.) ; Ventilating Air Conditioning ( V.A.C ) and Heated
Ventilating Air Conditioning (
H.V.A.C) equipment designed for use in potentially explosive atmospheres.
The
main , original , unique feature of this equipment is that safety is achieved by
air purging rather than by the more common use of explosion proofing. This novel
approach offers advantages both in the size and weight of the equipment as well
as performances .
Each
unit is ATEX Group II 2 G certified EExp IIC T3 and systems are
totally enclosed and maintained at an overpressure with respect to the outside
atmosphere by means of clean air. This totally eliminate the corrosion of copper
heat exchange components associated with traditional systems installed in harsh
environments .
Main
specifications of water coolers and air conditioners:
Cooling
capacity : 200 to 12 000 Kcal/hr or 800 to 50 000 Btu/hr
Ambient
operating conditions : - 20 to + 60°C
Chilled
water/antifreeze ( brine ) flow : 200 to 2 000 L/hr
Conditioned
air flow : 250 to 1 250 Sm3/hr
Condensing
unit water cooling : max.water temperature 50 °C ; water flow depends on
application
No
condensation of water on cooled surfaces due to the low dew point of
pressurising air.
Enclosures
are ingress protected to IP65 so may readily be sited outdoors with no
additional protection.
Range
of water coolers and air conditioners:
Systems
may be supplied with air or water cooled condensing unit
( water cooling is recommended ).
Systems
with water cooling condensing unit are rack mounted , removable .
An
optional heater may be fitted in the reservoir of the chiller units (R.W.C.H.)
or in the air loop of air conditioners (H.V.A.C.).
The
Air conditioner may also be fitted with dust and condensate removal features .
Air
conditioners can also be used to provide
overpressure of a room where an explosion hazard can exist in this case the
fan is engineered for the application.
