Warehouse in Polohy-Chobitky: four 10 kW cassette split systems for heating and cooling

Photo 01: The image shows final setup and connection of the outdoor air-conditioning units. A Ventall specialist is performing commissioning on the first unit in the row. The units are placed on individual metal anti-vibration stands mounted on a concrete base along the wall. Each unit is connected via insulated copper lines that minimize refrigerant losses and improve system durability. This linear arrangement simplifies future servicing and gives free access to each unit.

Photo 02: The image shows the rough-in stage of engineering installation at the site. A Ventall specialist working from construction scaffolding is connecting utilities to a high-capacity ducted indoor unit or a supply unit section. The unit has substantial size and weight, so it is fixed to the concrete slab with reinforced large-diameter threaded rods. A key part of the installation is the use of vibration-isolated hangers, which prevent transmission of vibration from the motor to the building structure and maintain acoustic comfort.

Photo 03: The image shows an installed cassette-type indoor unit integrated into the ceiling zone of the site. The unit is rigidly fixed to a steel I-beam, preventing vibration transfer to the sandwich roof panels. The professionally routed drain lines and refrigerant lines in white protective insulation are neatly laid along the steelwork. The decorative panel distributes air in four directions, helping maintain a stable temperature in medical halls with large amounts of equipment and staff.

Photo 04: The image shows the connection node of the indoor cassette unit. The white plastic drain pipes are clearly visible, routed along the steel profiles with the required slope for gravity drainage. Power and signal cables are protected with corrugated insulation that meets fire-safety standards for medical facilities. The unit is installed to provide free access to the service panel without blocking the main lighting sources in the hall.

Photo 05: The image shows the connection node of the indoor cassette unit to the mains. The refrigerant lines are protected with quality thermal insulation and additionally wrapped with protective tape to prevent condensation and shield the copper from external impact. The white PVC drain pipe is laid with a precise slope for effective moisture drainage from the unit's tray. The entire assembly is suspended from reinforced threaded rods attached to a steel beam, which is standard Ventall industrial installation practice for sites with exposed ceilings.
