UKAS-4 - Air conditioning unit assembly
A complete air conditioning assembly for cabins and rooms, both underground and on the surface. It lowers the temperature where people work, and comes as a ready‑to‑use system, not a set of parts to assemble.

// DESCRIPTION
What it is
An operator in a hot cabin works slower and makes more mistakes. UKAS‑4 is a ready‑to‑use system that changes this. Air directed to the cabin flows through the evaporator and transfers heat to the evaporating refrigerant, so it enters already cooled.
The same assembly serves a machine cabin in a mine working, a control room, a workshop, or a social room. There is only one condition: the area must not be at risk of exceeding permissible gas and dust concentrations, and the ambient temperature must not exceed 50 degrees Celsius.
You receive a complete assembly. The UKAS‑4/230VAC/ZS controller powers the chiller and controls it. You connect the UKAS‑4/230VAC/ZZ power supply unit to a 500 V/50 Hz IT isolated network, and it delivers 230 V AC to the controller. You do not need to select anything separately.
