High Density Cartridge Heater (RAC)
The form of construction of these heating elements, allows its use in adverse conditions, such as vibration and high temperatures and that can reach over 500 ° on the surface of the cartridge.
Consult in each case with our technical department.
High Density Heaters (RAC), are ideal for the installation of a high power in minimal space.

Instructions (for guidance) to place and mount
HOLE TOLERANCE CHART
The adjustment of the cartridge in the hole is very important for the proper functioning and performance.
The regulation of the temperature is essential and for this we recommend to place the measuring point not more than 15mm separately from the cartridge.
Connection types for cartridges with built-in THERMOCOUPLE
We can place thermocouple type J (Fe Cu Ni), type K (Ni Cr Ni), type T (Cu Cu Ni)
If the customer says otherwise the thermal sensor is installed always insulated to avoid problems on sensitive control devices.
OPTION 1. THERMOCOUPLE ON THE CARTRIDGE BASE ISOLATED
STANDARD Placement of the thermocouple. Right choice to avoid problems sensitive control devices.
OPTION 2. THERMOCOUPLE ON THE CARTRIDGE BASE GROUNDED.
Option indicated when rapid measurement is required.
NOTE: This option is not valid for highly sensitive regulation devices
OPTION 3. THERMOCOUPLE ISOLATED AND CENTERED
This option can be performed on elements from 3/8 “(9,52) ø
CARTRIDGE HEATERS WITH PT-100 SENSOR
They can be manufactured as follows:
Position 1. Starting from 6.35 mm ø.
Position 2. Starting from 12.50 mm ø.
