Description
The EVA-340 HS is a high-static industrial evaporative cooler from Evapoler’s “HS” series (Hi-Static) designed for large-scale air movement and cooling. It is intended for factory halls, workshops, warehouses and similar large spaces where long-distance air throw and fresh-air supply are needed. According to the manufacturer, it offers “100% fresh, clean & cool air” and is “Green & sustainable evaporative technology”.
The model is built for high static pressure and long-distance air delivery.
Key Specifications
According to Evapoler's published specs:
Airflow: approx 34,000 m³/hr (≈20,000 CFM) for the EVA-340 HS.
Static pressure: 40 mm wg (millimetres water gauge) for HS series models.
Power: 7.5 kW (for this model) at 415 V / 50 Hz supply.
Vent (discharge) size: 900 × 900 mm (L×W) for the EVA-340 HS.
Side & back cooling pad sizes: Back Pad: 770 × 1530 × 100 mm (2 Nos.). Side Pad: 620 × 1530 ×100 mm (2 Nos.).
Dimensions: 1850 × 2100 × 2150 mm (L × W × H) approximately (±100).
Net weight: 435 kg; Operating weight (with water) approx 835 kg.
Tank capacity: 400 litres.
Evaporation (cooling) efficiency: around 85%.
Key Features & Benefits
High static pressure & long-distance air throw: The HS series is explicitly designed for “high static air pressure and long distance air delivery”.
Energy efficiency: Because evaporative cooling replaces traditional refrigerant-based cooling in many scenarios, Evapoler claims usage of up to ~80% less electricity compared to conventional air conditioning.
Fresh air & air quality: It provides 100% fresh air (not just recirculated), helping with dust, odour and fumes removal in industrial spaces.
High-performance build quality:
Honey-comb cooling pads (high saturation levels) for effective evaporation.
100% copper windings in motors, aluminium casing for heat dissipation.
AMCA certified forward-curved DIDW centrifugal fan.
Rust-free stainless steel tank, pre-dust filters, float valve, water level monitoring.
Customisable & easy maintenance: Designed for easy access, filters, pads, and belts/pumps. The cabinet is powder-coated GP sheet for durability.
Typical Applications
Large industrial halls, factories, manufacturing plants, warehouses.
Spaces which benefit from high-volume, long-throw air delivery rather than only spot cooling.
Environments where energy efficiency and fresh air ventilation are priorities (for example hot & dry climates).
Workshops or settings where dust, heat, exhaust fumes need to be expelled and replaced by fresh air.
Installation & Considerations
Ensure adequate clearance for the unit’s size (approx 1850×2100×2150 mm) and for the discharge vent (900×900 mm).
Because static pressure is high, ductwork and discharge openings should be designed with minimal resistance (fewer elbows, smooth transitions) to maintain performance.
Water quality & maintenance: The evaporative pad system and sump tank (400 L) require regular maintenance: cleaning, checking float valve, ensuring non-clogging distributor.
Power supply: 415 V, 50 Hz (three-phase) required. Ensure motor protection, correct wiring.
Suitable for dry/hot climates; in very humid ambient conditions evaporative cooling efficiency may drop.
Noise: ≤70 dBA when installed correctly.
