Product catalog summary

Introduction
Rooftop units are crucial in the HVAC industry due to their comprehensive design, ease of installation, cost-effectiveness, and versatility. The RTACS series is tailored for heating or cooling spaces such as cinemas, shopping malls, and restaurants. These units can be remotely controlled via microprocessor and integrated with building management systems. They offer 27 main and 340 intermediate models, with cooling capacities from 8 kW to 500 kW, and can function in ambient temperatures from 5°C to 56°C.

Features and Benefits
The units are constructed with specially rolled steel profiles and panels with double-layer sheets and insulation options. They are Eurovent certified with 50 mm rockwool insulated panels. The exterior is made of electrostatically painted galvanized steel, with special rubber gaskets to prevent air leakage. The evaporator and condenser coils consist of copper tubes and aluminum fins, tested under 40 bar pressure. High-efficiency scroll compressors and independent cooling circuits are used for capacities over 25 kW. Safety features include emergency stop buttons and safety switches.
