For Sale - SRP - 3120 - Cartridge Heaters

Ace Heat Tech offers cartridge heaters both high watt and low watt density. These heaters are designed for a long life and outstanding performance.

Applications:
Cartridge heaters can be specified to meet the demand of special applications:
- Moulds and dies.
- Labeling machines
- Packaging equipment
- Laminating equipment
- Heating liquids and gases

High Watt Density Cartridge Heater:
The construction of this type varies from Low Watt Density Cartridge heater in two aspects. The space between ceramic bricks and the tube filled with selected grain size of high purity Magnesium Oxide (MgO). This is swaged to an extent of producing excellent heat transfer capability and dielectric strength and long life.

The tube used to house the ceramic brick arrangement is of SS 316 sheath or Incoloy 800 with maximum watt density of 12 Watt/sq. cm.

Features:
- Nickel - Chromium resistance wire precisely wound on a Magnesium Oxide core.
- Heavy wall Incoloy or SS 304 sheath provides for maximum protection against oxidation and corrosion.
- High purity Magnesium Oxide is thoroughly compacted and the entire assembly is swaged to give the excellent heat transfer.
- These are available with inbuilt thermocouple 'J' or 'K' type.
- Termination of heaters can be supplied as per customer's choice.

Technical specification:
- Maximum voltages: 240 V in 1/4" and 480 V in 1"
- Maximum ampere: 4 in 1/4"
- Wattage tolerance: + 5 percent, - 10 percent
- Resistance tolerance: + 10 percent, - 5 percent
- Length tolerance: +/- 2 percent
- Diameter tolerance: +/- 0.05
- Maximum temperature: 800 Degree C.
- Min. length: 25 mm in 1/4" and 45 mm in 1"
- Max. length: 600 mm in 1/4" and 1500 mm in 1"

We maintain stock of over 100 sizes of High Watt Density Cartridge Heater of standard diameter ranging from 1/4 inch (6.30 mm) to 1 inch (25.4 mm)

Low Watt Density Cartridge Heater:
Coil is made up of helically wound coil of Nickel Chrome wire. This coil is passed through specially designed circular ceramic bricks in such a way that it is evenly stretched to form stacks of ceramic bricks. This arrangement is housed in a tube of SS 304 sheath with maximum watt density of 4 watt/sq, cm.

Technical specifications:
- Diameter tolerance: +/- 0.3 mm
- Length tolerance: +/- 1.5 percent mm
- Wattage: 4 W/cm2 (max.)
- Wattage tolerance: + 5 percent, - 10 percent
- Connection voltage: 230 V
- Optional: 400 V (max.)

Testing information:
Quality control systems include following inspection procedures:
- Resistance test
- Inspection of physical test
- Voltage breakdown test
