Description
The EVA-750 HS is a large-capacity industrial evaporative cooler in Evapoler’s “HS” (High Static) series. According to the manufacturer, it delivers 100% fresh, clean & cool air, is green and sustainable, and is engineered for high static pressure applications (i.e., where air must be pushed through ductwork or long distances).
It is aimed at big industrial spaces, warehouses, factories, where you need high airflow volume, good throw/coverage and fresh ventilation rather than recirculated cooled air.

Features & Benefits
High static air delivery: The unit is explicitly specified for “high static air pressure and long distance air delivery”.
100% fresh air supply: Ideal for industrial spaces where ventilation alongside cooling is important (dust, odour removal, fresh air exchange).
Energy-efficient & lower operating cost: Manufacturer claims up to ~80% less power consumption compared with conventional refrigerated air conditioning.
Robust, industrial-grade build:
Honey-comb cooling pads with high saturation levels for effective evaporation.
Heavy duty submersible water pump, rust-free stainless steel tank, non-clogging water distributor.
100% copper-wound motor, AMCA certified forward-curved DIDW centrifugal fan (for optimal performance under static load).
Pre-dust filters to prolong pad life and maintain air quality.
Large coverage suitable for big halls: With the airflow & coverage figures given (75,000 m³/hr, ~9,000 sq-ft), it’s designed for substantial space.
Typical Applications
Given its specification, the EVA-750 HS is well‐suited for:
Large manufacturing plants, warehouses, automobile or heavy-engineering workshops.
Facilities where long-throw ducting/air delivery is needed (rather than simple open space cooling).
Environments where fresh air intake is important (not just cooling recirculated air) — for instance for dust, fumes, smells, or process ventilation.
Climates where evaporative cooling is effective (typically hot & dry to moderate humidity) and large volumes of fresh air are acceptable.
Installation & Considerations
Ambient suitability: Evaporative cooling works best when ambient air is reasonably dry; in high humidity the cooling effect will be less pronounced.
Ducting & static losses: Because this model is built for 40 mm wg static pressure, duct design must be well done: minimal bends/elbows, smooth duct transitions to avoid excessive losses.
Water supply & quality: Ensure availability of clean water, proper pad maintenance, pump and water tank setup. The 500 L tank capacity means it must be sized/integrated appropriately.
Power supply & infrastructure: The 18.5 kW motor (415 V/50 Hz three-phase) demands adequate electrical infrastructure, protection, wiring.
Space & access: The large footprint (~2.9 m × 2.9 m) and height (~2.48 m) mean you need clearance for installation & maintenance access.
Maintenance: Although evaporative coolers are simpler than refrigerant AC in some respects, regular maintenance of pads, filters, water distributor system, and cleaning the tank are important to get expected performance long term.
Ventilation requirement: Since this is a fresh-air system pushing new air into the space, ensure proper exhaust/air-outlet so the space does not become over-pressurised and recirculation or heat gain occurs.
