Helix Earth^™

Advanced Humidity Control Code-Ready Ventilation Drier Air, Healthier Spaces Drop-in Solution Lower HVAC Energy Use

From space to your rooftop. The first retrofit system that gives commercial buildings fresher air, lower humidity, and lower energy costs without replacing a thing. Powered by NASA technology.

The Problem

A 100-Year-Old
Problem Nobody Fixed

For over 100 years, air conditioning has done two jobs at once: cooling the air and removing moisture. That combination is the problem. In humid climates, removing moisture consumes up to 80% of your AC’s energy. Compressors work overtime. Equipment wears out faster. Utility bills climb. Mold takes hold. And comfort is still terrible. The industry's answer has always been, "That's just how it works."

We disagree.

Key Benefits

Meet Helix MICRA^™

The filtration breakthrough powering our bolt-on solution for separating humidity from cooling. No more overcooling. Your AC works less. Your building performs better. Your equipment lives longer.

Fresh Air, No Humidity

Bring in more outdoor air without the humidity penalty. Lower CO2, eliminate odors, and stop mold before it starts.

Equipment That Lasts

Helix Earth™ strips moisture before it reaches your AC. Less strain on compressors. Fewer breakdowns. Longer equipment life.

Lower Energy Bills From Day One

When humidity is handled separately, your AC uses dramatically less energy.

Code-Ready Ventilation

Meet ASHRAE outdoor air requirements for up to 5x less cost than other systems.

Bolt-On, Not Rip-and-Replace

Retrofit onto existing rooftop units with no major construction and no downtime.

Built on NASA Technology

Engineered from technology originally developed for spacecraft life support and proven under extreme conditions.

Technology

How It Works

We follow a systematic process to deliver high-quality product.

STEP 1

Separate Humidity from Cooling

Traditional HVAC forces your compressor and coils to cool humid air, wasting massive energy overcooling air just to fight moisture.

Helix Earth removes humidity first. Dry air flows to your cooling system. Your AC finally does the one job it was designed to do, instead of two.

STEP 2

The Helix MICRA™ Filter

Our patented filter is unlike anything commercial HVAC has ever seen.

What makes it different:
Helix MICRA™ filter is a rigid material embedded with helical channels. Think of it as a precision-engineered sponge that spins liquid droplets out of airflow and captures them instantly, with no moving parts.

Liquid desiccant sprays into incoming humid air
Desiccant absorbs moisture on contact
Helix MICRA™ filter separates desiccant droplets with moisture from dry air with minimal pressure drop
Unique design virtually eliminates carryover

STEP 3

Closed-Loop Regeneration

Our regenerator removes the water from the desiccant
Dry, cooled air flows to your HVAC system
Warm, humid air vents to the outdoors

The result:

Compact, lightweight systems that fit where others can’t
No drains. No plumbing.
Continuous operation with minimal maintenance

Use Cases

Why Helix Earth Technology Changes Everything for HVAC

Precondition Outdoor Air

Dry and filter incoming air before it ever touches your cooling system.

ASHRAE 62.1 and 90.1 Ready

Hit ventilation and efficiency targets without blowing your capital budget.

Equipment That Lasts Longer

When your AC is not fighting humidity, not just compressors, the entire AC unit run easier and break down less.

Real Comfort at Higher Setpoints

Dry air feels cooler. Raise your thermostat and make your occupants more comfortable.

Energy Efficiency

Your AC uses less energy when it is not fighting moisture.

The Performance Advantage That Started at NASA

Competing technologies utilize membranes, structured packing, thin films, or solid desiccants. These are all slow, large, and energy-intensive.

Helix MICRA™ accelerates mass transfer by orders of magnitude. Faster process. Smaller footprint. Lower energy draw. That is what makes a true bolt-on retrofit possible.
