Pre-engineered and customizable dehumidification architectures built to withstand challenging marine and subtropical moisture loads.
Engineered for extreme dew point depression down to -70°C, integrating deep sensible pre-cooling for ultra-dry lithium battery production and pharmaceutical encapsulation.
Integrated climate shell, low-leak envelope design, and multi-stage refrigerative pre-treatment built to international cleanroom and GMP manufacturing metrics.
Sub-cooling condensation recovery array designed to extract VOCs and N-Methyl-2-pyrrolidone vapors with over 99% operational recovery efficiency.
Synergistic cryogenic deep-cooling condensation combined with regenerative thermal oxidation (RTO) for chemical, coating, and timber processing plants.
New Zealand's unique geography—defined by maritime boundary layers, high ambient relative humidity (often exceeding 80–90% in regions like Auckland, Waikato, and the Bay of Plenty), and strict bio-security compliance—creates intensive latent load demands across essential processing hubs.
In dairy processing capitals like Canterbury and Southland, seasonal ambient moisture swings distort spray drying yields and provoke hygroscopic agglomeration. Our refrigerative pre-coolers strip mass latent loads from intake air before reaching primary heat exchangers, ensuring standard moisture ratios and eliminating seasonal throughput drop.
Marlborough’s winemaking industry and Hawke's Bay fruit preservation depots depend on non-fluctuating thermal and relative humidity envelopes. Uncontrolled vapor pressure leads to barrel evaporation, label mildew, and premature enzymatic breakdown. Hangzhou DryAir delivers refrigeration cycles tuned precisely above freezing points to avoid surface desiccation.
Sub-zero logistics facilities across Tauranga Port and Christchurch encounter severe frost accumulation on evaporators, causing expensive defrost cycles and slick flooring. Mechanical refrigerative dehumidifiers pre-treat air at loading docks to condense high-humidity maritime drafts before entering deep-freeze chambers.
Evaluating refrigeration-based moisture removal against desiccant chemistry: optimizing psychrometric transition zones to cut kilowatt consumption per kilogram of water extracted.
Refrigerative dehumidifiers operate on basic Carnot thermodynamic principles: warm, moist process air passes across an evaporator coil chilled below its dew point temperature. Water vapor condenses into liquid runoff, and the chilled, saturated air is reheated by passing over the condenser coil before supply.
Where processing targets demand dew points beneath 5°C (such as lithium battery assembly or effervescent pharmaceutical processing), mechanical refrigeration faces mechanical frost barriers. Here, Hangzhou DryAir utilizes refrigerative DX pre-cooling coils as the upstream stage, extracting 70-80% of ambient moisture before the air hits our desiccant rotors.
Operating from Qingshan Industrial Park in Hangzhou, DryAir leverages automated sheet-metal fabrication, robotic seam-welding, and comprehensive thermodynamic test stations to provide international markets with verifiable engineering excellence.
Validated by global tier-one enterprises including Tesla, Northvolt, CATL, BYD, and TTI. Our systems sustain non-stop operational availability inside gigawatt battery lines where unpredicted downtime carries astronomical operational costs.
Certified under both civil ISO 9001 systems and the rigorous GJB national defense framework. Every unit undergoes aerodynamic wind-tunnel benchmarking, refrigerant pressure integrity verification, and helium mass-spectrometer leak audits prior to dispatch.
Equipped with globally serviceable industrial components: Copeland or Bitzer scroll/screw compressors, Danfoss expansion valves, Schneider electrical controls, and low-GWP refrigerants (R410A, R134a, R513A) aligning with New Zealand's Climate Change Response Act.
Importing industrial thermal equipment into New Zealand demands meticulous alignment with local health, electrical, seismic, and environmental standards.
Control consoles, motor starters, and VFD modules are systematically assembled following AS/NZS 3000 electrical standards. Complete IP55-rated enclosures, segregated extra-low voltage control paths, and verified short-circuit ratings guarantee seamless sign-off by registered New Zealand electrical inspectors.
Given New Zealand’s high seismic activity, our structural frames incorporate reinforced base skids engineered according to NZS 4219 specifications. Structural calculations and dynamic load anchors accommodate peak horizontal accelerations encountered across Wellington, Christchurch, and Bay of Plenty facilities.
Hangzhou DryAir supports low-GWP refrigerant options compatible with the New Zealand Synthetic Greenhouse Gas (SGG) levy framework. Pressure equipment structures comply with AS/NZS 1200 / ASME pressure vessel fabrication tolerances, paired with burst protection valves and accessible service manifolds.
