Description
The EVA-170 HS from Evapoler is a high-static industrial evaporative (direct) cooling unit designed for situations where large volumes of fresh air must be cooled and distributed over long duct runs or into large spaces. It belongs to the “HS” series (High Static) — which indicates its suitability for heavier duty ducting, longer throw, or situations where it needs to overcome higher resistance (ducts, filters, fans) compared to simpler evaporative coolers.
Key Specifications
Based on manufacturer-published data:
Airflow: ~ 17,000 m³/h for the side discharge version.
Static pressure: ~ 40 mm Wg (~392 Pa) for the 17,000 m³/h model.
Power: ~ 2.2 kW motor for this particular variant (17,000 m³/h).
Voltage/Frequency: 415 V / 50 Hz as standard for the HS series.
Discharge options: Side / Top / Down configurable in the HS series.
Body / Cabinet Info: While exact material specs for this model aren’t fully listed, HS series units from Evapoler highlight heavy-duty build, use of thick honeycomb pads (~100 mm) and industrial-grade motors/blowers.
Features & Highlights
High static capability: The 40 mm Wg (~392 Pa) static pressure indicates the unit can drive air through more substantial duct lengths or with multiple outlets. This is useful if your installation has duct resistance or you need long throw.
Large air volume: With ~17,000 m³/h, it’s suited for large halls, workshops, industrial spaces, or duct‐distribution systems rather than simple blowers.
Evaporative cooling efficiency: As part of the HS “evaporative cooling” suite, it uses large cellulose/paper honeycomb pads, water evaporation to cool air (no refrigerant cycle), and is thus more energy efficient under favourable ambient conditions (dry/hot, good ventilation). For example, documentation shows HS units offering up to “~15°C drop for suitable ambient” and “up to 80% lower electricity cost” in certain scenarios.
Flexible installation: The discharge type (Side/Top/Down) allows flexibility in mounting (roof, wall, floor) depending on your layout.
Industrial build: As per the HS series sheet, components like copper-wound motor, thick pads, mist eliminator, large tank (for some models), heavy-duty blower, filters are standard.
Suitability & Use-Case
Given its specs and features, the EVA-170 HS is especially well suited for:
Large industrial halls, warehouse spaces, manufacturing units where fresh air intake and cooling are required (not just recirculated cooled air).
Ducted air delivery systems where the cooler must push cooled air through ducts, vents, possibly multiple outlets.
Environments with substantial heat loads (machinery, lighting, people), and where ventilation + cooling is needed rather than just closed-loop air conditioning.
Applications where the ambient air is suitable for evaporative cooling (i.e., relatively lower humidity, or good airflow/ventilation to remove humidified air).
Situations where energy efficiency and fresh air are priorities (for example, want to avoid high-cost refrigerant AC, or need ventilation for dust/fume removal).
Considerations & Installation Tips
Ambient humidity & ventilation: Evaporative cooling’s performance depends strongly on ambient relative humidity. In high humidity conditions, the temperature drop will be less. Also, because it introduces fresh or outside air, the space must allow for air to escape (exhaust, openings) so that humidity doesn’t build up and reduce comfort.
Duct layout and static losses: Because this unit is designed for higher static pressure, you still need to ensure your ductwork, bends, diffusers, filters do not exceed its capability. Ensure you estimate duct resistance and select accordingly.
Water system & maintenance: Although specific tank size isn’t given for this exact model, HS series documentation references tanks and pad maintenance. Regular cleaning, pad inspection, pump maintenance, water quality and drainage matter.
Electrical supply: Check that your site has (or can handle) 415 V / 50 Hz supply (likely 3-phase) as indicated for this model. Confirm motor current draw, breaker size, wiring.
Installation space & access: Consider mounting height, airflow direction, clearances for maintenance (pad replacement, filters, blower access). For example, large footprint typical of HS units; the specification sheet lists dimensions for 17,000 flow model ~1600×1840×1650 mm ±100.
Noise & actuation: Industrial blowers can generate noise; ensure acoustic planning if installed near sensitive areas.
Expect realistic performance: The 17,000 m³/h and 40 mm Wg are ideal conditions; real performance will vary with pad condition, ambient air humidity, duct design, cleanliness of filters and water system.
Integration with system: Since this is a “direct evaporative” unit delivering fresh air, consider how it integrates with building ventilation, how humidified air is managed (especially if you already have HVAC or dehumidification systems).
