LTA750-04 (950C)

Description

Airtorch Model: LTA750-04 (220V/230/240V, Nominal 4kW). 50/60Hz. The maximum inlet temperature is 75°C.

Maximum Outlet ~925°C/950°C. Use from 40°C to 950°C output depending on the flow.**

Temperatures above 870C should be attempted with a precision control power regulator like the BPAN-O-PLUS and a very accurate mass flow meter

The unit is a cartridge-type hot Air Generator. 4 kW Total Power (Nominal @ 240V Single Phase).

If the supply is 208V, please note that one will only obtain a maximum of ~3.3 KW. For 230 V, the power draw will be 3.9 KW. For a 277V single phase, the temperature is restricted to the output of 500°C and requires the BPAN-O-PLUS.

Unit Description: LTA Airtorch® Heavy Duty Industrial Air Heater System Model LTA750 series is an inline air heater with continuous hot air discharge designed to generate hot air temperatures of ~900°C continuous use or 950°C with intermittent use.   The LTA 750-04 has an Outlet 2″ NPT.   Inlet 1/2″ NPT male. Inlet gas not to exceed 75°C.

The picture shown may be illustrative only.  Several Airtorch® units come with an in-built Type “K” thermocouple.

Such hot air guns find applications in combustion, plastic welding, heat shrinking of thermoplastics, ceramic drying, on-site heat treatment, plastic forming, and many more. The unique steel shell construction provides efficient heat recovery and management, providing high-efficiency, high-temperature discharge. This recuperating design eliminates radiant heat loss while enhancing efficiency and maintaining a cooler outer shell temperature.

Note: Parts of the surface are hotter than 50°C (DO NOT TOUCH) during use, providing greater operational efficiency but will be hot to the touch. Please wear high-temperature gloves. The LTA series has a 1/2″ NPTM compressed air fitting for the air/gas inlet.

**MHI may substitute a  4 KW LTA (LTA750-04) with a 4 kW MTA925 (a costlier and higher-performance product, MTA925-04; click here) because of inventory, customer requests, electrical or physical supply issues, or inventory availability issues arising from requests.

Please note that the LTA and MTA products require a flow meter to set the correct flow.  In the most common configuration, a compressed air gas source is connected to the flow meter, which regulates flow into the LTA or MTA925.  The minimum Air flow is close to 8 SCFM at full power.   If using at minimum flow (close to maximum temperature), please monitor the temperature and ensure the flow does not fall below this value when the power is on.

Unit Features:

• Steel Shell Construction (LTA or MTA versions)
• Built-in Type K thermocouple
• Lightweight with a compact, ergonomic design
• 208/220/230/240V plug-in design
• Rapid heat-up
• Compressed Air/gas compatible
• Outlet 2″ NPT. Inlet 1/2″ NPT male

Specs:

• Dimensions: Unit: 4.0″ dia x 15.5″ L (slightly different for the MTA925-04 when susbstituted)
• Air Inlet: Compressed Air or Gas (DO NOT USE COMBUSTIBLE GASES) Air Outlet 2″ NPT fitting. Inlet 1/2″ NPT male.
• Weight: Lightweight with a compact, ergonomic design
• Temperature: ~900°C continuous or sometimes even 950°C with intermittent use for the MTA925.  If an MTA is substituted for an LTA, the unit will be rated to the LTA temperature.
•  Airflow: ~6.5  to 8  SCFM for 900C (maintain minimum otherwise Airtorch™ may burn).  For temperatures above 850 °C, please use the BPAN-O-PLUS temperature and power control; –  for high temperatures, please consider using the MTA925-04.
• Voltage: 208/220/230/240VAC Frequency: 50/60 Hz
• Current: ~ 18 Amps @ 208/220/230/240VAC  4 kW Total Power (Nominal @ 240V). 4 KW is the power at 240 V.  If the supply is 208 V, please note you will only obtain a maximum of ~3.3 KW. For 230V, the power draw will be 3.9 KW.
• Power Consumption: ~ 4000 Watts Output Nominal at 240V Single Phase.
• Optional Power Control: The optional BPAN-O-PLUS allows you to vary the output temperature by changing the airflow or the output power.
• The flowmeter is not included.
• Standard Accessories:
• Display – Not included
• Built-in thermocouples can be linked for external display.
• If a Control Panel is required. The BPAN-O-PLUS is recommended. Please click here.
