Water channel cooler for round air duct VEAB CWK 315-3-2.5 – Ø315 mm 1410m3 1260L/PU 8.3KW

The CWK 315-3-2.5 is installed directly in a circular air duct and uses chilled water as the energy carrier. This allows the air passing through the ventilation system to be cooled without the need for a direct evaporative freon heat exchanger.

The design is designed for easy maintenance - the housing has an opening cover for inspection and cleaning , and condensation is drained via a stainless steel tray and a G½" drain connection.

📐 Dimensions

According to the current VEAB technical documentation for CWK 315-3-2.5 :

💨 Cooling power

Cooling capacity is not a fixed value . It depends on the flow rate and temperature of the air, its humidity, as well as the temperature and flow rate of the cold water.

For example, at water 6/12°C , the VEAB table gives the following indicative results for CWK 315-3-2.5:

These values are indicative design points and not constant product output. For a specific system, VEAB recommends calculating according to the actual air and water parameters.

💧 Management and automation

The CWK itself is a water-air heat exchanger . For automatic temperature control, the system can be supplemented with:

temperature controller → sensor → control valve → servomotor → frost protection.

For example, VEAB lists a two-way valve ZTV15-1.6 (Kvs 1.6) for the CWK 315-3-2.5 as a suitable option in its selection table.

This is important for the product page – control components should not be presented as included by default unless the specific offer explicitly states so.

💦 Condensation drainage

When cooling warm and humid air, the temperature of the heat exchanger can drop below the dew point and condensation can form.

Therefore, the CWK is equipped with a stainless steel tray that collects the water and allows it to be drained via a G½" drain connection .

🛠️ Construction and maintenance

The heat exchanger uses copper tubes and aluminum fins , and the casing is made of protected sheet metal. The opening cover provides access to the interior for periodic cleaning and inspection.

Rubber seals on the round connections facilitate its integration into the ventilation system.
