Continental AP, one of the largest factories in Romania, has once again chosen our company for a large-scale project – the realization of the new ventilation and air conditioning system in the Calendering, Extrusion and Cutting areas in hall 1.

The project led by Eltrex as a general contractor includes four packages:

  • Metallic structures
  • HVAC
  • Electrical installations
  • BMS and automation

Regarding the package of metal structures, Eltrex executed and installed 6 platforms to support the CTAs, with a total weight of 140 tons of galvanized steel. The platforms are mounted outside, their legs being built inside the hall, either by lining the existing concrete pillars, or by installing new pillars. We made and installed an indoor platform on 2 levels (20 tons of steel) for the cooling station. We also made a protective wall in the High Bay Storage area (15 tons of steel).

The HVAC project consisted in the acquisition and installation on the external platforms of 6 CTAs of 45000m3 / h, 3 CTAs of 40000m3 / h, 1 CTA of 30000m3 / h. They were equipped and connected to the pipe sections built inside. A new chiller with a cooling capacity of 1244 kW and a cooling tower with a cooling capacity of 1450 kW were purchased and installed. I completely modified the old cooling station, which contained 3 chillers, in order to be able to integrate the new chiller. We connected 10 pumps to serve the new cooling system. We also made over 40 sections of ventilation pipes, with lengths between 50 and 80 m, made entirely in the production area.

In terms of electrical installations, we executed 3 switchboards for automation and automation of CTAs, a switchboard for power and supply chiller, two switchboards for supply and control of pumps, 2 switchboards for distribution and a switchboard for UPS. We delivered and installed over 200 field elements such as: sensors, pressure switches, actuators, three-way valves necessary for the proper functioning of the HVAC system to CAP standards. We executed the cable routes over the production area, always taking care not to affect the technological flow and respecting all the normal OSH. The new panels were powered using over 3000 m of NYY-J 1x150mmp cable and 2000 m of NYY-J 1X185mmp cable.

Regarding the BMS and automation part, we performed the local automation of the CTAs and the cooling station (chillers, cooling tower, pumps) by taking over 3500 signals from the field and we developed their automatic control software . The whole system works automatically, keeping the temperature in the halls constant, depending on the setpoints set in the BMS. All equipment has been integrated in the BMS (WinCC platform) so that the customer can monitor and control each element individually. At the same time, from BMS the beneficiary can follow the evolution of consumptions in the form of a graph but also in relation to the temperatures and the degree of humidity in the hall.
