BEYOND ENERGY SAVINGS: THE GHT ADVANTAGE
While standard HRV/ERV systems struggle in extreme temperatures, the GHT Geothermal Pre-conditioning module acts as a "force multiplier" for your ventilation—protecting your building's physics and delivering unmatched indoor climate stability.
Building Risks Avoided
-
Winter Defrost Imbalance Prevents negative pressure cycles during standard defrost modes, which draw freezing air through micro-cracks and compromise building integrity.
-
Ductwork Condensation & Mold Strips excess moisture from humid summer air, physically stopping mold spores from developing inside your ventilation ducts.
-
Summer Overheating (Fake Bypass) Unlike a standard HRV bypass that blows hot +30°C (+86°F) outdoor air directly indoors, GHT actively cools the air first.
-
Peak Electricity Spikes Completely removes the reliance on energy-hungry electric pre-heaters (PTC/TEN) during sub-zero winter days.
Premium Comfort Gained
-
True "Free Cooling" Utilizes the earth's natural thermal inertia to cool incoming summer air, costing only the minimal power of a small circulation pump.
-
Active Dehumidification Lowers absolute humidity to create a crisp, highly comfortable indoor climate, eliminating the "stuffy" and muggy summer feeling.
-
Maximized HRV/ERV Lifespan Keeps your core ventilation unit operating in its optimal, safe temperature zone year-round, extending equipment longevity and efficiency (COP).
-
100% Guaranteed Air Balance Delivers continuous, uninterrupted, and perfectly balanced fresh air 365 days a year, regardless of extreme outdoor weather events.
How GHT Pre-Conditioning Works
Forget inefficient electric pre-heaters and fake summer bypasses. See how harnessing the earth's stable temperature guarantees 100% continuous air balance and true free cooling.
Nature’s Energy, Engineered.
Stop fighting humidity with expensive electricity. GHT uses sable 12°C (54°F) ground energy to passively cool and dehumidify your air.
100% Frost protection. Even at -22°C ( -8°F ) and beyond, GHT delivers 0°C (32°F) air to your ventilation unit without electric heaters.
See the Technology in Motion.
The GHT Solution is engineered to address the most critical challenges of modern ventilation. Traditionally, HVAC systems struggle to pre-condition air without massive energy spikes. Our technology utilizes the stable temperature of the earth to passively pre-treat incoming air—delivering it to your unit at an ideal range.
