DEFROST SYSTEMS
For room temperatures where ice-build up can be expected
and where the coil can not be defrosted by the room air, an
defrost system is available. Water defrost
On top of the coil block a removable water defrost tray is
Heating section mounted. The height of the water defrost tray is 80 mm,
The air cooler can be carried out with a heating section with which increases the total height of the air cooler. The
electric heating elements to heat up again dehumidified air standard discharge head of the water in the water defrost
The heating section is compared to the air flow placed after tray is 25 mm, the maximum speed in the water supply line

holders against the coil block or completely integrated in the the temperature of the defrost water must be between + 15
casing. ° C and at + 30 ° C. The water defrost tray is executed with
handles, easy for disassemble and cleaning.
Hot gas defrost
The coil block is as standard suited for hot gas defrost ( hot
gas supply through the suction header). Against an extra
price the drip tray can be provided with a copper hot gas
spiral. This is enclosed in aluminium profiles that are rigidly
secured to the under side of the aluminium inner drip tray.
As a result, a very good heat transfer is realized. As with
electric defrost a distinction is made with light defrost (room
temperature around 0 ° C) and heavy defrost.
FAN HEATING
The fan fan heating prevents ice build-up between
the fan impeller and fan bellmouth during the defrost
cycle. This prevent damaging of the fan. Connection box

DEFROST SOCKS
(Draw-through air coolers)
The defrost socks may be used at draw-
through air coolers and optimizes defrosting
in particular freezing applications.
In the cooling phase and activated fans, the defrost
sock is inflated. In the defrost phase, when the fans
are turned off, the defrost sock close the the fan hole
and supports the defrost process of the coil block.
Execution
Suitable for food industry, 100% polyester endless

-60 to 110 ° C, very flexible, Fire resistance E
(EN13501-1: 2003), double stitched, tear resistant. Standard execution

Advantage
The defrost sock prevent draw in the air cooler during the
defrost process. The heat remains in the air cooler and
ensures that the defrosting time is considerably shortened.

• Lower absenteeism through draft-free workplaces
• Optimal climate for sensitive products
• No condensation, because of the breathable
fabric no dew point exceedance occurs.
Attention!!
When selecting the air cooler, you need to take pressure loss into account.
