The H-Block units are made of original frameless sandwich panels, registered with the Industrial Property Office in its database of industrial designs. The structure of the unit chamber consists of 50 mm thick frameless sandwich panels. The shell is made of two steel zinc plates with a thickness of 0.8 mm. Inside the panel is mineral wool insulation with volume weight 50 kg/m³.


These air-conditioning units are made as one complex unit. The units are designed for installation on the floor, and are delivered with a base frame. Suction and exhaust holes are located on the upper side of the chamber and are equipped with flexible adapters with end flanges for connection to pipes. Output pipes of exchangers, service holes and fittings are located on the service side of the unit. Access to ventilators, filters and the frequency convertor is provided by doors that are fitted with latching hinges.
