Description
The EVA-1700 HS is part of Evapoler’s “HS” (High Static) series of direct evaporative cooling units designed for large scale industrial spaces where there is a need for fresh-air supply, high airflow and long throw / high static pressure capability (i.e., the system can push air through ductwork or over large distances). According to the Evapoler specification sheet, the model has discharge types Side/Top/Down and is designed for very large capacity.
The “HS” designation indicates suitability for heavy-duty industrial installations (factories, large workshops, warehouses) rather than smaller room-cooling units.
Key Specifications
Based on the catalogue data, here are the known specification highlights for EVA-1700 HS:
| Parameter | Typical Value / Notes |
|---|---|
| Airflow | 170,000 / 100,000 (units likely m³/hr / CFM) |
| Static Pressure Rating | 40 mm wg (millimetres water gauge) |
| Motor Power | 22 kW × 2 units (i.e., dual motors) |
| Supply Voltage / Freq | 415 V / 50 Hz (Three-phase) |
| Vent Size (WxH) | ~ 1260 × 1260 mm – 2 nos. for major discharge |
| Cooling Area Coverage | Up to ~ 20,000 sq ft (approx) |
Note: Some values such as airflow “170,000/100,000” may be indicative of two configurations (e.g., side vs top discharge) or may represent m³/hr vs CFM; it's important to confirm exact units with the manufacturer. Also, “22 x 2” motor notation indicates two motors each 22 kW.
Features & Benefits
High Static / Long-Throw Capability: With a 40 mm wg static rating, the unit is designed to overcome duct resistance or deliver air across large spans.
100% Fresh Air Supply: As an evaporative cooling system, the unit draws in fresh air, passes it through cooling pads and supplies into the space—helping with ventilation, removal of dust/fumes/odours.
Energy Efficiency: Evapoler’s HS series is advertised to reduce electricity use by up to ~80% compared with traditional refrigerated AC systems in suitable ambient conditions.
Robust Industrial Build: Key components typically include heavy duty submersible water pump, rust-free stainless steel tank, high-efficiency honeycomb cooling pads, 100% copper-wound motors, AMCA certified centrifugal fans. (These features come from the HS series brochure for other models)
Adaptable Mounting: Side / Top / Down discharge configurations allow flexibility in mounting (roof, floor, wall) depending on space and duct layout.
Large Coverage: With airflow and capacity geared for very large spaces, it is suited for large industrial halls, manufacturing plants, warehouses.
Typical Applications
Large industrial halls, manufacturing plants, heavy-engineering workshops, warehouse spaces with high heat loads.
Situations where fresh ventilation + cooling are required (not just recirculated air).
Facilities where ducting of cooled air or long-throw supply is needed.
Regions with hot and relatively dry ambient because evaporative cooling performs best in such conditions.
Installation & Considerations
When planning to install the EVA-1700 HS, here are important considerations:
Ensure ambient conditions are suitable for evaporative cooling — high humidity will reduce the temperature drop performance.
Ductwork and discharge design must minimize losses (fewer bends, smooth transitions) to take advantage of the high static capability of the unit.
Power supply: Two motors at ~22 kW each means a substantial electrical infrastructure (three-phase, proper protection, wiring, starter etc).
Water supply and maintenance: The system will need adequate water supply, pad maintenance (cleaning / replacement), sump/tank management, drainage/overflow safety.
Clearance / footprint: Big unit size means space around for maintenance access. Also orientation (side/top/down) has to match building layout.
Noise and vibration: Large industrial fans may require acoustic treatment or vibration isolation in certain environments.
Exhaust / Out-flow: If supplying fresh air into a space, ensure there is appropriate exhaust or air path (so that air does not become trapped or recirculated in inefficient manner).
