UKAS-650/B - Air conditioning unit
The power machine of the cooling system, featuring a screw compressor. It compresses the refrigerant and forces its circulation, lowering temperature and humidity in underground workings and high‑risk rooms.
// DESCRIPTION
What it is
There is no cooling without a chiller. UKAS‑650/B increases the refrigerant pressure and gives it kinetic energy, forcing flow in a closed circuit. Cooling occurs through refrigerant evaporation, either in a direct expansion evaporator or an indirect chiller, depending on the system's operating mode.
An electric motor‑driven screw compressor handles the compression. The design was developed for refrigeration and air conditioning. It operates in single‑stage and multi‑stage systems, with all typical refrigerants and many process gases, so you can match it to the installation you already have.
An N‑ARPEX disc coupling, made of steel and multi‑plate, transfers the drive. Torque is transmitted precisely and without backlash, even when the shafts are not perfectly aligned. Less stress on the shaft means longer operation without downtime.
The device operates in rooms with "a", "b", or "c" degree of methane explosion hazard, and in class A or B coal dust explosion hazard rooms.
UKAS‑650/B works with SHPAS and CHPAS coolers, the CHWAS evaporative cooler, and the PAS evaporator.
