PAS - Evaporator
A direct expansion evaporator for underground workings and high‑risk rooms. It cools the air without intermediary chilled water, right where your crew works.
// DESCRIPTION
What it is
High temperatures cost money. They shorten working time, lower efficiency, and increase risk. PAS cools the air directly. The refrigerant flows through the copper tube exchanger core, counter to the air stream, making heat exchange more effective.
The housing is made of steel sheet and features handles to suspend the evaporator at the workplace. You can also mount it on a support structure, on feet, or on skids. A built‑in anemometer continuously measures the amount of flowing air.
The connections are compatible with evaporators from other manufacturers, so replacing the device does not require rebuilding the installation. PAS works with UKAS chillers manufactured by ATUT or chillers from other manufacturers with similar parameters.
The device operates in underground mines and tunnels, in rooms with "a", "b", or "c" degree of methane explosion hazard, and in class A or B coal dust explosion hazard rooms. The safety level according to the PN‑EN 60079‑0 standard is Mb.
