Description and Design:
The Circular Duct Water Coolers (CWC) are designed for cooling ventilation air in systems or individual rooms. They feature circular duct connections, a chilled water coil with three tube rows made from hydrophilic aluminum, and a stainless steel drip tray for condensate collection. The casing is made of Aluzinc-coated sheet steel, and the unit includes an openable cover for easy inspection and cleaning. The duct connections have rubber seals, ensuring air tightness class D to EN 15727.

Operating Data:
Maximum operating temperature is +110°C, and maximum operating pressure is 1.0 MPa (10 bar). The coils are tested for leakage.

Capacity and Installation:
The CWC units are available in six standard sizes and must be installed in a horizontal duct with airflow in the arrow direction. They require external regulators, sensors, valves, and actuators for control, which are not included.

Dimensions and Model Marking:
Each model is marked with its duct diameter and number of tube rows. Dimensions vary by model, with specific measurements provided for each size.

Capacity Details:
Capacity data for models CWC 125-3, CWC 160-3, CWC 200-3, CWC 250-3, CWC 315-3, and CWC 400-3 are detailed, including water temperature in/out, air flow, air pressure drop, inlet air temperature, inlet air humidity, outlet air temperature, output, water flow, and water pressure drop.

Product Warranty:
The product warranty covers malfunctions under normal operating conditions for 24 months from the date of the manufacturer's invoice. Warranty service is provided free of charge for issues arising under normal conditions, but any unauthorized manipulation voids the warranty. Contact an official "Ventmatika" dealer for service.
