CIRCULAR DUCT WATER HEATERS

 

CWC/CWH

 

 

 

 

The  duct  water  heaters  CWC/CWH  with  circular  duct  connections  are  designed  for 

heating/cooling the ventilation air in a ventilation system. The CWH/CWC can also be used for heating 
or cooling individual rooms or zones. For controlling the room or supply air temperature, the duct 
heaters can be supplemented with regulators, sensors, actuators, valves and anti-freeze protection.  

 

9 standard sizes (9 heaters and 9 coolers);  

 

Water coils with 2 or 3 tube rows (cooler with 3 rows only); 

 

Casing of Aluzinc coated sheet steel, AZ 150; 

 

Openable cover for inspection and cleaning; 

 

Circular duct connections with rubber seals; 

 

Air tightness class D to EN 15727; 

 

Coils are used with water (

0/+110°C

), as well as glycol (-

40/110°C

);
