Water cooler Lessar LV-CDTW 500x250-3 E16 is designed for rectangular air ducts, providing efficient cooling within ventilation systems and targeted indoor zones. Its robust construction and thoughtful design support stable operation under demanding conditions.
Main Features
This cooler operates at a maximum water pressure of 1.6 MPa (16 bar), enabling the use of cold water or antifreeze glycol solutions as heat carriers. The unit is optimized for air velocities between 2 and 3 m/s in the duct cross-section, which ensures balanced airflow without excessive resistance. Fluid speed inside the cooler reaches up to 2.5 m/s, improving heat exchange performance.
Hydrofil coating on the heat exchanger fins enhances water drainage, reducing the risk of corrosion and maintaining efficiency over time. The 3-row heat exchanger configuration allows effective cooling capacity in a compact design, suitable for diverse ventilation setups. Eight standard sizes are available to precisely fit various channel dimensions.
Design and Construction
- Body crafted fr om sheet steel with aluminum-zinc coating ensures corrosion resistance while maintaining durability.
- Heat exchanger tubes and connection nozzles made of copper combined with aluminum fins guarantee efficient thermal conductivity.
- Integrated drip eliminators prevent water carryover into the air stream, protecting ventilation components and improving indoor air quality.
Installation Recommendations
The cooler must be installed strictly in a horizontal position to facilitate proper condensate drainage and venting. Incorporating a slight tilt during mounting aids water removal and prevents accumulation inside the unit. For flanges exceeding 400 mm in length, an additional clamp-clip is necessary to secure connections reliably.
A siphon is not included and should be arranged separately to handle condensate disposal. When placing the cooler behind suspended ceilings, ensure sufficient access for maintenance and service operations.
Application Scope
Lessar LV-CDTW 500x250-3 E16 is suited for ventilation systems requiring air temperature control in commercial or industrial premises. Its compatibility with both water and glycol solutions makes it adaptable for environments wh ere freeze protection is crucial. The unit efficiently supports zone-specific cooling, contributing to improved climate management and energy savings.
