HT-DG90A1 Industrial Dehumidifier | 90 L/D Moisture Control

HT-DG90A1 is an industrial dehumidifier option for warehouses, production rooms, storage areas and equipment spaces where moisture control affects comfort, corrosion risk, product storage or process stability.

Capacity90 L/D
PowerAC220V-50Hz
Airflow420 m³/h
Selection factors: At 90 L/D with 420 m³/h of circulation and 1,200 W, this model covers a medium workshop or store without needing three-phase power.
Placement check: keep air inlet and outlet paths clear, plan drainage where needed, and avoid positions where condensate or dust can block airflow.

Application fit

Where this model fits, and what to verify first

Best fitMedium workshops, storage rooms and light production areas on a 220 V supply.
Check firstWhether 90 L/D covers the daily load with margin, and whether the 420 m³/h air path reaches the whole room.
AvoidUsing it in a large open warehouse where the moisture load will exceed 90 L/D.
Buyer noteA middle step in the range: more capacity than the 60 L/D unit while staying on single-phase power.

Best-fit Applications

This unit suits rooms where moisture builds through the working day: a workshop with wet processes nearby, a medium store, or a room where damp air puts tools and stock at risk. The 420 m³/h airflow helps distribute dry air across a medium space rather than only around the unit.

It stays on a 220 V single-phase supply, so it can go where three-phase power is not available, while the 1,200 W draw is higher than the compact model and should be planned into the circuit.

  • Workshops: holds humidity down where damp air affects tools and finished work.
  • Medium stores: protects cartons and metal parts across a larger footprint.
  • Light production: keeps working conditions stable in a humid but not wet room.

Selection guide

  • Moisture load: target litres per day for the room, allowing for door traffic.
  • Air distribution: use the 420 m³/h circulation to cover the room, not just one corner.
  • Drain route: plan continuous drainage for long running periods.
  • Supply: single-phase 220 V, with a circuit sized for 1,200 W.
  • Temperature: check the working range where the room runs cool.

What NOT to Buy

HT-DG90A1 Industrial Dehumidifier | 90 L/D Moisture Control technical and selection table
Situation Risk Better action
Load exceeds 90 L/D The unit runs continuously without reaching target RH. Confirm the load, then consider the HT-DG158A-B.
Very large open space A single 90 L/D unit cannot hold a big warehouse. Use larger capacity models or several units.
No drain route Continuous running fills the tank fast. Arrange a gravity or pump drain first.
Ignoring air path Dry air stays near the unit, leaving far corners damp. Check circulation and clearances.

Industrial Dehumidifier Buyer Checklist

Use the source-backed product information on this page as the starting point, then confirm site conditions before approving the final model.

  • Daily moisture load and door-opening frequency
  • Room volume against the 420 m³/h circulation
  • Continuous drain method and route
  • 220 V circuit sized for 1,200 W
Selection note

HT-DG90A1 is positioned for compact industrial humidity control; confirm capacity, drainage and site humidity load before final selection.

Quality Assurance & Warranty

Dehumidifier orders are verified at the factory before shipping, because a unit sized for a humidity target is only useful if it arrives working to that target.

Applied to this model: Capacity 90 L/D, Power AC220V-50Hz. These checks are run against that specification before the unit ships.

Unit-level humidity checkChecks cover compressor start, coil and drain integrity, airflow, humidity sensor response and model-to-table parameter matching.
Documented complianceCE LVD/EMC and RoHS files cover the listed HT, LG and HT-DG dehumidifier families; see the documents section below.
Warranty supportWarranty for dehumidifier orders is confirmed with the quotation for your destination market.

OEM/ODM & Supply Options

For distributors and contractors working on moisture-control projects, the supply side adapts to your market instead of one fixed cabinet build.

For this model (Capacity 90 L/D, Power AC220V-50Hz), the OEM route can start from that base specification rather than a blank sheet.

FAQ

How do I choose dehumidifier capacity?

Estimate the daily moisture load in litres and check that 90 L/D covers it. The 420 m³/h airflow matters too, because it decides how evenly dry air reaches a medium room rather than just the area near the unit.

Can it run continuously?

Yes, with continuous drainage. It runs on 220 V at 1,200 W, so plan the circuit and the drain route before installation, and confirm the room load stays inside 90 L/D. Check the filter regularly, keep the 420 m³/h air path clear, and confirm the drain runs freely. In a workshop with airborne dust, filter cleaning is the item that most often gets missed.

Why do some model names differ?

Some source rows use HT model codes while the website/PIM layer may use LG model codes. Both are shown to avoid silent normalization.
