General Description
The AM-4 is an electrically powered dry heat warmer that supplies external heat to the L-fusion disposable warming bag. The L-fusion set is placed between the two aluminum heating plates in the AM-4.
*Operating temperature:
 AM-412 : 31 ºC - 40 ºC (87.8 ºF - 104 ºF)
AM-413(AM-412-T) : 30 ºC - 37 ºC (86 ºF - 98.6 ºF)
Flow rate:
 0 ~ 60ml / min (gravity flow), 0 ~ 160ml / min (using an infusion pump)
Safety:
Three independent circuits for prevention of overheating, audible and visual alarm circuits, fire prevention safeguards, splash-resistant, dry heat
Size/weight: 266 (H) x 182 (W) x 78.5 (D) mm / 3kg
* Effluent temperature is affected by initial fluid temperature, room temperature, flow rate

Standard Type (Model : LF-D)
 
 
  1) Automatic Temperature Control
Heating is controlled by one effluent temperature sensor and two heating plate temperature sensors.
  2) Temperature Display
Easy to read by LED display shows the temperature of the fluid. Accurate fluid temperature increments of 0.1 ºC degrees.
 
  3) Alarm
An audible buzzer and visual alarm are activated at a fluid temperature of
41.5 ºC (AM-412), 39 ºC (AM-413).
The alarm buzzer volume is adjustable.
 
  4) Spare fuse
A spare fuse is included inside the AM-4 unit.
     
  5) Quick set-up
The L-fusion set is placed directly between the heating plates.
 
  6) Rapid warm-up
Ready to use in 2~3 minutes
     
  7)

Safe performance
Protection from over-heating, electric shock and contamination.
Protection from air bubbles is provided via the air chamber in the L-fusion disposable set.
 
  8) High durability
Simple construction and shock resistant.
