DH-18ASY
18000 m3/h, 1.1 kW, 380V manual or 220V LCD.
Mobile evaporative coolers and portable spot coolers from Foshan, China — duct evaporative units, refrigerant spot coolers and small portable coolers for workshops, warehouses, farms and outdoor venues.

A duct evaporative cooler is an evaporative cooler with a duct. The duct is the point: it lets you put the unit where water, power and air intake suit, and deliver the cooled air where people or animals actually are. The DH-ASY series is built for exactly that — portable on casters, axial, with a 300-litre tank and a duct discharge.

Every figure in that table comes from the manufacturer's product page for the duct series. Within a size, the standard and BP versions differ only in voltage and control; airflow, body, water use and tank are identical. That makes the choice straightforward: pick the size on airflow, then pick the version on your site's voltage and on whether you want manual or multi-speed LCD control.
A duct lets one unit serve a zone rather than a spot. In a workshop, that means cooled air aimed at the line, not at the wall behind the unit. In a warehouse, it means air delivered to the picking face rather than diffused across the whole volume. In a poultry or greenhouse building, it means air where the animals or plants are. The cost is pressure and placement: a duct run needs routing, the unit needs intake air, and the space still needs an exhaust route, because evaporative cooling adds air to the building and that air has to leave. None of that is a reason not to use a duct. All of it belongs in the layout conversation before ordering, not after delivery.

Before ordering, confirm: the exact model and voltage for your site, the airflow and size you need, MOQ, lead time, and warranty. This page lists only what the source material verifies; anything not listed here is a question to ask, not a specification to assume.
Send your space size, heat source, and voltage, and ask for a layout using the equipment families on this page. Before payment, confirm MOQ, lead time, voltage, and warranty for your order.
