REFURBISHMENT OF TRANE A LENNOX ROOFTOP UNITS

At present, the company is engaged in intense work on the project of energy saving measures implemented on rooftop air-conditioning units manufactured by TRANE and LENNOX, U.S. based companies. The project has been in progress for two years, during which we have refurbished 82 shopping centers in the Czech Republic and Slovakia, in total representing more than 400 rooftop units.

The refurbishment consists of the delivery and installation of a new electrical switchboard and a controller with newly developed and implemented software. At the same time, we install new gas burners manufactured in Sweden. This equipment is certified and has high safety of operation and low emissions.

The unit is equipped with new functions contributing to the compliance with hygienic standards, which effectively use the different temperatures inside and outside the building and save energy in the form of electricity, gas and hot water. The system is linked to the controller bus. The system visualization is created and installed to the computer in the maintenance office. Respective parts of the equipment, sensors and protective features are displayed in the visualization. A potential defect as well as temperature, CO2 volume etc. may be easily detected.

The visualization is accessible by connection to the internal network through the remote desktop, which enables monitoring the system also from the service center.

The company operates a dispatch center and emergency service in the Czech Republic and Slovakia.
