CIRCULAR DUCT WATER HEATERS
CWC/CWH
3
The duct water heater CWH can be installed in a horizontal or vertical duct, with the air flow in
either direction. The heater should not be fitted too close to a fan outlet or a bend in the ducting
because then there is a risk that the air flow through the heat exchanger is uneven which might result
in lower efficiency. The heater is normally fitted after the fan.
The heater is controlled by external
regulators, sensors, valves and actuators, which must be ordered separately.
The duct water cooler CWC can be installed in a horizontal duct only, with the air flow in either
direction
.
The duct water cooler is partly insulated. A drain pipe is required to drain off any condensed
water with drain connection of G
½
. The heater is controlled by external regulators, sensors, valves
and actuators, which must be ordered separately.
The heat exchanger must be cleaned regularly in order to retain the best performance from the
heater/cooler. The cleaning interval depends on the air cleanliness and on the correct maintenance
of the whole system.
The heat exchanger is easily accessible for cleaning when the lid of the heater/cooler is
removed. Whole heater/cooler can be cleaned by compressed air, water or steam.
