CHWAS - Evaporative cooler
An indirect evaporative cooler for underground workings and high‑risk rooms. It removes heat through water evaporation and connects to group or central air conditioning.
// DESCRIPTION
What it is
High temperatures cost money. They shorten working time, lower efficiency, and increase risk. CHWAS cools the air indirectly. A forced air flow through the cooler, for example by a fan, meets the water spraying system, thereby removing heat.
The cooler consists of two elements: the cooler and the drip tray. The housing and the tray are made of steel sheet. Handles facilitate transport and installation at the workplace.
CHWAS operates in group or central air conditioning systems. The connections are compatible with coolers from other manufacturers, so replacing the device does not require rebuilding the installation. It 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.
