CIAT Equips Bulgaria's Burgas and Varna Airports

CIAT has installed more than 40 rooftop units to ensure the air quality in the new terminals of Burgas and Varna airports, which were inaugurated last summer. Delivered in just two months' time, CIAT's Space PF rooftop units reduce energy consumption and feature high-efficiency filtration systems.

New terminals have been added to the existing infrastructures at Bulgaria's Burgas and Varna airports to cope with the increase in air traffic. The Space PF rooftop units installed by CIAT will heat and cool the air in these terminals, from lobbies and departure lounges to technical premises and utility rooms.


All 44 rooftop units are IPF MRC 11 units, i.e. they are reversible (they cool and heat) and integrate auxiliary heaters that supplement the thermodynamic circuit when it is unable to keep up with demand.

Thanks to their tandem compressors, free-cooling function and active heat recovery system, which reclaims waste energy from exhaust air, these units offer the highest energy efficiency.


CIAT's Space rooftop units also help with the air exchange in the terminals by extracting stale air outdoors and drawing fresh air indoors. They feature high-efficiency F7 filtration systems with activated carbon filters that trap odours.

The models installed at the terminals range in size from IPF 90V MRC 11 to IPF 1200V MRC 11 and each have cooling capacities of 30 to 350 kW.

Although the required delivery times were very short, all 44 units were manufactured in just two months!
