Description
EAST SDD Series · Model SDD-138L The SDD-138L removes up to 138 liters (290 pints) of moisture every 24 hours at 30°C / RH80%, while hanging safely overhead so every square foot below stays usable for plants, racks and equipment. Engineered for overhead duty and long-term reliability — every feature converts into real benefits for your grow room or warehouse. Feature: thickened frame metal plate body designed for permanent ceiling installation. Advantage: strong enough to be mounted overhead for years without sagging or vibration. Benefit: install it once and forget it — zero floor space occupied by your humidity control. Feature: clear structural design and refined manufacturing crafts on every unit. Advantage: smooth airflow channels and tidy internal layout improve heat-exchange efficiency. Benefit: consistent dehumidifying performance and easier maintenance over the machine’s lifetime. Feature: world-famous compressor, large heat exchanger and centrifugal fan as standard. Advantage: high airflow with low energy consumption and reduced operating noise. Benefit: lower running costs and lower overall investment for owners. Built-in intelligence and flexible accessories let you match the unit to your exact growing or storage conditions. Pre-wired with a comprehensive logic circuit. Plants need different humidity at different growth stages — set the target for each stage directly, no extra controller purchase needed. Third-party controller systems can also be connected on SDD OEM models when requested in advance. Choose normal, medium-efficiency or high-efficiency filters to match your air-quality and branding requirements. Duct kits can be connected on both inlet and outlet, so airflow can be routed exactly where your space needs it. Full parameters in both imperial and metric units. Different capacities match different room sizes; the SDD series covers up to 960 L/D (2020 pints) for the largest grow operations. The SDD-138L overhead design suits any space where floor area is precious and humidity must stay under control. Suitable humidity is essential for plants. Set stage-by-stage targets to maximize growth performance. Keep goods in a stable humidity condition and protect inventory from moisture damage. Refrigeration-type dehumidification in two simple cycles — air circulation and refrigerant circulation. Wet air is drawn into the machine and passed through the heat exchanger. Moisture condenses into water on the condenser, and dry air is released back into the room. High-pressure refrigerant liquid is throttled by the capillary and evaporates in the evaporator, absorbing heat from the air. The compressor then raises it to high-temperature, high-pressure gas that releases heat in the condenser — completing a continuous drying loop. EAST is open to branding buyers worldwide. From private control panels to full production supervision, customize the SDD series to your market. Your own panel layout and branding on every unit. Specifications, logo printing and name plate making all provided. Combine functions to fit your market requirements. Monitor production via videos, photos or formal inspection reports; order tracking system keeps your business on schedule. Wood packing is a must for international dehumidifier shipping. To port or to door — flexible, reliable and affordable solutions that fit your business. Long-term support that protects your investment from day one. The SDD-138L typically covers 1300–1500 sqft (90–120 m²). Actual coverage depends on room height, airflow and moisture load — our team can help you size the right model. Yes. EAST is an OEM/ODM manufacturer: private controller panel, logo printing, name plate making, extra function combinations and buyer-supplied manuals are all available on request. Yes.
