nnnn

PTC based convection heaters for

nnnn

controlling the formation of condensation

nnnn

within electrical cabinets or for using in

nnnn

areas subjected to the action of frost or

nnnn

ice formation.

nnnn

• Compact heaters from 15 to 150 W;

nnnn

• IP65 protection type;

nnnn

• Seawater resistance anodized aluminium;

nnnn

• Ready to install;

nnnn

• Custom sizing and power for all applications.

nnnn

INSTALLATION NOTES

nnnn

• Big cabinets need more heating power and

nnnn

require multiple heaters ( parallel connection ).

nnnn

Ask us about specific power and length;

nnnn

• To maximize convection effect prefer a

nnnn

vertical installation and ensure a minimum

nnnn

clearance of 50 mm around heaters;

nnnn

• PTC based heaters are self- power and

nnnn

temperature limiting appliances. No additional

nnnn

safety devices are normally needed;

nnnn

• Use a hygrostat/thermostat for triggering

nnnn

■M heating at a preset level of relative

nnnn

||y humidity/cabinet-temperature ( keep

nnnn

ON heating circuit even when cabinet is

nnnn

powered OFF).

nnnn

POWER CALCULATION

nnnn

• Use the following formula to calculate the

nnnn

required electrical heating power:

nnnn

P = K x S x At

nnnn

P-> required heating power in Watt;

nnnn

K-> transfer coefficient in W/m2 °C;

nnnn

Depending on cabinet material:

nnnn

K = 3,5 W/m2°C polyester cabinet;

nnnn

K = 3J W/m2°C stainless steel cabinet

nnnn

K = 5,5 W/m2°C painted sheet cabinet;

nnnn

K= 12 W/m2°C aluminium cabinet.

nnnn

S-> equivalent cabinet surface in ml;

nnnn

At-> required temperature difference between

nnnn

internal (target) and external cabinet

nnnn

temperature.

nnnn

MOUNTING OPTIONS

nnnn

Clips to a

nnnn

35 mm DIN rail;

nnnn

• Screw mounted (four mounting holes);

nnnn

Please ask us for special fastening options.
