Substation & Control House Cooling
Cooling for transmission and distribution control houses, relay and protection enclosures, and e-houses across the Denver region.
Protect relays and controls in harsh conditions
Relay switching and protection equipment in a T&D control house has to keep working through heat waves, blizzards and dust storms. Overheated control houses lead to nuisance trips, shortened equipment life and costly outages.
PrecisionAir units are designed to operate efficiently in the extreme conditions energy professionals work in. BBCOND installs and services them on control houses, relay enclosures and electrical houses for utilities, cooperatives, renewable developers and industrial owners.

Serving sites within an hour of Denver
Substations on the plains and along the foothills face wide temperature swings, high winds and hail. NEMA 3R construction, galvanized or optional stainless steel housings and a -40°F to 131°F operating range suit Colorado yards. We work on sites within about an hour of Denver and coordinate with utility safety and access requirements.
