Quick facts
The Fujitsu UTZ-KXRA high humidity insulation kit is the genuine supplementary insulation for the Fujitsu AIRSTAGE AUUH circular flow cassette. Fujitsu lists it on the spec sheet for its AUUH systems under the name “High Humidity Insulation Kit”.
When the ceiling space gets humid
The circular flow cassette is often used in stores, restaurants or large rooms, with capacities from 18,000 to 48,000 BTU. In some of these places, the air in the ceiling space becomes hot and humid, especially in summer. The UTZ-KXRA kit then supplements the unit’s original insulation. In a dry ceiling space and an ordinary room, it is rarely needed.
Cassettes listed by Fujitsu
- AUUH**KUAS: H-series R-32 circular flow cassette
The right kit for the cassette
Fujitsu offers two high humidity insulation kits. The UTZ-KXRA goes on the AUUH circular flow cassette; the UTZ-KXGC goes on the ACUH compact cassette. During the visit, we assess the humidity of the space and tell you whether the kit is warranted.

Frequently asked questions
Is my cassette compatible?
Fujitsu lists the UTZ-KXRA for the H-Series AUUH**KUAS circular-flow cassette. Send us your cassette’s model number and we confirm.
Do I need it?
Rarely in an ordinary space. In a restaurant, shop or humid ceiling space it can be justified: we assess it during the visit.
Can I use the UTZ-KXGC instead?
No. The UTZ-KXGC is meant for the ACUH compact cassette; the circular-flow cassette takes the UTZ-KXRA.
Can you install it?
Yes. We fit it with the cassette, everywhere in Greater Montréal.
