A Thermocold Airtop rooftop unit with gold-coloured condenser coils and an R454B badge sits in front of a wall listing the range: AIRTOP, AIRTOP ONE, AIRTOP XL and AIRTOP MEGA, with capacity bands such as "CC: 16 - 60 kW" and "HC: 14 - 58 kW". Open-frame units and the blue portals of the stand appear behind.
