AQUATRAP® AT450S All-Temperature, High-Capacity LGR Dehumidifier
“As good, if not better, than any other LGR high-temperature dehumidifier on the market…” – Kurt Bolden, Hydro Lab
The powerful AQUATRAP AT450S All-Temperature, portable LGR Dehumidifier from Abatement Technologies® delivers unsurpassed structural drying power for large-scale commercial water restoration projects. The anodized aluminum AT450S has the capacity to remove 180+ pints per day at AHAM, with performance optimized at 95° F. But what really sets the real-life performance of this LGR dehumidifier apart from the competition is its ability to outperform under a wide range of jobsite conditions. As a result, your crews can efficiently remove water at high temperatures (up to 125° F), at low temperatures (33° F), and everywhere in between!
Superior dehumidification performance features of the AQUATRAP AT450S LGR Dehumidifier include:
- 180+ pints/day water removal @ AHAM and up to 300 pints/day @ saturation
- Powerful 450 CFM airflow
- Exceptional grain depression
- 33° F to 125° F operating range
- Performance optimized @ 95° F
- Unique automated heat pump defrost technology
Industry-Leading Heat Pump Technology for Faster, More Effective Large-Scale Structural Drying at Both High Temperatures and Low Temperatures
State-of-the-art heat pump technology provides the AT450S High-Performance LGR Dehumidifier with its unique ability to operate efficiently in all types of drying environments. This technology enables the AT450S to defrost only when needed, and to remove water even in defrost mode.
Superior “Beyond Bypass” Technology
Systems utilizing “bypass” technology must slow down airflow (cfm) by up to 50% as the air is cooled moving across the evaporator to condense water. Not so with the AQUATRAP AT450S that utilizes heat pump technology! The AT450S provides a constant 450 cfm airflow – especially in hot conditions above 100° F – keeping work crews productive and structures drying faster.
Lightweight Anodized Aluminum Cabinet
The cabinet of the AQUATRAP AT450S is made from a marine alloy of hard anodized aluminum. Anodized aluminum retains the basic advantages of aluminum while providing greatly improved durability, corrosion resistance and thermal resistance.

Easy-to-Operate
Automated user controls make using the AT450S a snap. Simply set it up and let it do the work. Additional ease-of-use features include a protected bottom drain that removes residual water from the unit and protects the internal pump from cracking when operating or storing in freezing temperatures.
